HPE Zerto Software Reviews

We've got two data centers, and for any of our applications that are not in some kind of a load-balanced or high-availability cluster, we use Zerto to replicate them, to make them as highly available as possible, without building that into the solution. We replicate between 100 and 150 different VMs from our North Carolina data center to our Chicago data center.

A small example of the way it's made things simpler is that we were building out a new product, and the original recommendation from the vendor when we were deploying that product was to have the application server closest to the end-users and the database server at our main data center in North Carolina. Once it was implemented, we found out that wasn't the case. We used Zerto to fail over the database to the same data center that the application server was in. We were able to do that really quickly and easily, without having to do a whole lot of extra work, such as having to rebuild the database server. That's one example of how we use Zerto, not just in a standard failover scenario. It made the process a lot easier than it would have been had we not had Zerto.

We have also used it when something happened to a configuration or a database file and it had become corrupted. It happened in the evening, after-hours. Rather than getting the backup engineer involved and trying to restore the files from a backup, we used Zerto to grab the file from a couple of hours previous, restored it, and got things back up and running really quickly. It's definitely a time-saver. We were able to handle it ourselves without needing to get anybody else involved.

One of the most valuable things about the solution is the ease of use when it comes to failing things over. The ability to easily test your failover capabilities is really nice. We can actually stand up a VM in an isolated environment, validate that the VM is up and running and that it boots properly, and we can do that in a matter of 30 seconds. Being able to show that to upper management, and that it's working the way it should, provides a lot of value.

It's one of the easiest products out there, as far as managing and using it go. The UI is pretty dead simple.

If everything is set up and configured properly, a failover of one or two systems can be done by one person. Nobody has to be involved other than the application owner, to validate everything, once the failover is done. It's a one-man show.

Continuous data protection is what it's supposed to do. Being able to bring a system up within a matter of minutes is the next best thing to having an actual high-availability cluster. If you're not building high availability into a solution itself, Zerto is the next best option. If we're talking about one or two applications or one VPG (Virtual Protected Group) a failover takes under five minutes, from the point of clicking "Start Failover" to the point of validating everything on the application end.

The only thing we've noticed that needs improvement is the backend cleanup within VMware. There are some little issues there. I would like to see tighter integration with VMware. From a recoverability standpoint, it's great when using VMware. But what we have noticed is that orphan data is an issue within VMware. It doesn't clean up properly when you're moving stuff around.

Our company has been using Zerto for several years. I took over management of it within the last six months, but I've dealt with Zerto in the past as well.

We've had no stability issues. We've had to open one or two cases on small issues, but they've been pretty trivial. There haven't been any critical issues with its stability.

It scales really well. Out of 500 VMs, we're using it for about 150 of them. That's probably not a lot compared to other Zerto customers. But as you add more ESX hosts to your environment, you just add new VRAs to the ESX host. There's not too much to have to worry about when you're scaling up.

We utilize it for everything that we don't build in a high-availability cluster. A lot of our stuff is designed as an HA cluster, but anything that is not designed that way is automatically protected by Zerto.

The technical support is as good as, if not better than, most of the technical support that we deal with. Opening tickets is easy. The support portal is easy to use. Depending on the severity—I've never had to open a Sev 1 case—Sev 2 and Sev 3 cases are answered within 24 hours.

We didn't have a previous solution.

I did not do the initial setup of the solution, but the upgrade from version 8.5 to 9.5 was very simple.

Our engineering team members, three systems engineers, are the main users of Zerto. We don't have segregated roles. I'm the point person for Zerto, and the other guys are backups for managing it and doing recoveries. Maintenance only requires one person.

We have seen ROI from a time-management standpoint.

I don't know if Zerto reduces the number of people that we need to have involved in a recovery scenario, but it definitely simplifies the process compared to using Commvault, which is our backup solution. If it's something that we need recovered from within a day or two, it's much simpler to recover that file with Zerto than it is from a backup solution like Commvault.

Anybody on our engineering team can probably recover a file using Zerto. I'm not so sure that's the case for Commvault. Our backup admin would probably have to get involved if we're doing a recovery from Commvault. Using Zerto, the UI is so much simpler.

There may be a small possibility that we will look at Zerto to replace Commvault whenever we do replace Commvault. That's a possibility, but it hasn't been brought up yet. We do know we are getting rid of Commvault at some point.

I've used other solutions, like Dell Avamar and Veeam. Veeam is definitely pretty easy to use and on par with Zerto. It's 100 times easier to use than Avamar. Ease of use is one of Zerto's strongest points.

Go for it. It's the best-of-breed for high-availability replication solutions. It really is dead simple to use and easy to implement and maintain. It's not one of those solutions that you have to spend hours a day managing. You look at it for five minutes a day and forget about it.

The biggest lesson I've learned from using Zerto is that high availability, having a good replication solution in place, doesn't have to be a big, complicated, scary mess. It can be simple. It doesn't have to be some huge hurdle that you have to overcome.

Zerto is our primary means of failing over our critical production loads that have a relatively low RPO/RTO. This is our use case for this solution.

What we like best about Zerto is its fast failover to another data center. It is simple and it works.

The limitation with Zerto is that you're required to have one Zerto Manager per virtual center, and this means that we're only able to replicate one way using this solution. Now, we are evaluating the clustering of Zerto with Microsoft clustering, so we can replicate both ways and both data centers, and have the management server in both data centers.

Historically, Zerto has started going into the backup space, and that is when they lost focus on keeping their replication product good. Now, it seems they're finally leaving that backup space, and they're just sticking with replication, so in version 9, they have fixed all of my gripes about the product, e.g. they now support VMware tags, Windows bringing over the time on the target side, etc. All of these little things, they are all correcting, because they're now sticking with the replication product.

It's been five years since I started using Zerto.

Zerto is a single use case product and it works flawlessly. It is stable.

Technical support for this product was absolutely fantastic, but that was before they were acquired by HP. They are still good, but I can tell the company is becoming too big.

We didn't previously use a different solution, as this was the first use case or first requirement that we needed to have under a 24-hour RPO/RTO.

The setup for Zerto was very simple.

We implemented this solution in-house. Implementation only took less than a day to complete. Zerto was ready to use in our environment for a DR (disaster recovery) exercise weeks later.

The return on investment from Zerto was immediate. Instead of having legacy DR failover exercises that involved multiple teams and weekends work of activity, now a single user can fail over everything and get reports to prove that it was failed over and the data integrity was all done. As far as people hours and time, the ROI was instant.

Zerto is fairly expensive. We are on a perpetual three-year subscription, but for my less than 300 VMs that we needed this functionality for, it is worth it. I'm not aware of any additional costs beyond the standard fees for this product.

We did evaluate Commvault LiveSync, Veeam, and Dell solutions, though I don't even remember what the Dell product was. We did go through RFP. We went with Zerto because it was simple and it worked, and we didn't have to worry about doing anything else.

We're a Commvault and Zerto customer.

We are on Zerto 8.5, and we are evaluating version 9 update 3.

I have no impression on the scalability of this solution, because we haven't really grown yet. We have 300 endpoints and we've always been in that range. I can't tell how Zerto fares if there's more than 300 endpoints.

We have a primary asset owner who uses this solution, who gets feedback from other IT infrastructure teams of whether their servers need to have a low RPO/RTO. That single asset owner will then put those in Zerto. For deployment and maintenance, we have the primary asset owner, then there's a backup person. The primary asset owner does everything, but if the asset owner isn't available, the backup person will help with support roles.

We don't have plans of increasing Zerto usage, as we've always had a relatively static critical VM count of around 300, e.g. we've gone down to 260, we've gone up to 300, but it's always in a range that's close to 300.

My advice to people looking into implementing this product is that if you have less than a 24-hour RPO/RTO and you need it to work in your target location, then there's no other product for it other than Zerto.

My rating for Zerto is a nine out of ten, because nothing is perfect. Nine is the best rating I could give for this solution, but the key takeaway is that it is a single use case product and it does the job.

Right now, we use it just for disaster recovery.

We have always had a centralized data center. Therefore, if we were to lose connectivity or power, then access to county resources would be cut off until that issue is resolved. If there is a hurricane, it would be the same thing. If we lose power, then we would be down until something comes up. With Zerto, I can quickly get us up and running at the disaster recovery site, provided it is still operational.

For most use cases, the failover time is a handful of minutes, if that. A single user can run the system.

Zerto will reduce the number of staff involved in a data recovery situation. As of now, we have been lucky. We have not had to deal with this type of issue. However, it will require less people going forward. So, I can dedicate people to other tasks in a situation like this.

Disaster recovery would initially require four or five people to handle just the server side. This has now been cut down to just one person.

It provides great continuous data protection. The RPOs on things are in seconds.

We have been using it for two years.

We haven't had any issues. It literally just runs. Once you have it set up, you just leave it alone.

As long as I have the resources and licensing, I can keep going from a scalability perspective.

The tech support on my latest issue wasn't so great. I had to figure a lot of stuff out myself. It could be that I had a Level 1 tech who was new or something, but it seemed like the tech was spitballing, which does not help me.

In previous instances, the technical support was great. They were able to get me up and running fairly quickly.

We didn't have a solution like this before that allowed for disaster recovery. Everything was restored from backup, then we had to wait. So, if something went south, then we would need to restore from a backup. I saw the Zerto product was literally one button click, then I can failover to a disaster recovery site and keep going. That was amazing during the initial review of the product. It was just easy.

We started looking at how long it would take to restore from a backup. Rebuilding that infrastructure would take hours, if not days, as opposed to having the ability with Zerto to do a single click, then we are up and running at another site.

It is being used in conjunction with our legacy backup solution.

It was actually fairly easy to set up the solution. Installing it, creating the VPGs, and adding the VMs to it was fairly straightforward.

Working with support on the line, we deployed Zerto in a couple hours.

It is about $1,000 per VM, so it is pricey. However, the cost and time (the manpower cost) that it would take several members of IT to restore a backup and every individual piece of the virtual environment would easily exceed the pricing cost.

If we had to trigger it, downtime would go down to whatever the RPO is at that time. Right now, our RPO average is between four and 10 seconds. This is a big cost saver for us. Anytime certain systems are down within the organization, money is lost.

The only negative part that I have seen so far has been the cost. It is kind of pricey, but you get what you pay for. Zerto is a lot faster than other solutions and you get enhanced performance.

Eventually, we will expand solution use. While there are some competitors in the market, I don't think any of them get to the ease of use and speed that Zerto has. Even Veem has CDP, which is similar, but it is not as fast, user-friendly, or worry-free.

Veeam CDP was still fledgling at the time of our evaluation. It existed, but wasn't that great. It wasn't anywhere near as robust as Zerto. Commvault had something similar as well, but even their solution doesn't do disaster recovery as quickly as Zerto.

It is important that it has both backup and disaster recovery. As I am looking for a backup and recovery solution, I am looking for something that can do everything.

The solution was bought to help with the mitigation of ransomware.

Right now, we are still in a physical data center. We haven't looked at their solution for going to the cloud. That is something which is coming up. Eventually, we will make the switch over. Right now, we are working on a new backup and DR solution. So, that will go hand in hand once we are done with the on-prem.

I would rate Zerto as 10 out of 10 based on the way that the product works.

We use it for a hot DR site for our primary production environment, allowing us to fail over all of our production servers in case of an emergency.

We are in a much better position as far as our data protection scheme is concerned, with Zerto. Compared to where we were before, it's a night and day difference, because we didn't have the ability to immediately fail over our production environment. The difference is pretty extreme for our organization. We went from just having SAN snapshots to Veeam backups, and now we have replication.

It massively decreases the time needed for us to fail back because, before, we had no way to do so for our workload. It would have been a manual process to move our workload somewhere else. We would have had to get the VMs off of the existing infrastructure and we would have had to create a whole new infrastructure and get them running somewhere else. That could take two to three weeks, in an emergency situation, with our entire team working on it, versus just pushing a button and moving it right now. We're in a whole different realm now.

There would also be massive savings in manpower to do that. We would have to create a whole new infrastructure, whether in AWS, Azure, or even procuring physical equipment and deploying it. Now that we have Zerto in place, it's there waiting and being replicated too.

The fact that it just works is important to us. We don't have to do a whole lot to it. It does its thing in the background and it's ready to go. It enables us to execute our DR plan at any time that is required. It doesn't seem to require a lot of time or management or day-to-day maintenance. 

It doesn't "complain" a lot and it's ready to go at any time, so you could call it easy to use. It's just me responsible for maintaining it, and there is a network infrastructure person involved as well. But it mostly maintains itself, once it has been deployed.

It does what it's purported to do, which is to provide continuous data protection. We have a five-second RPO. It's definitely doing its job. It's there in the background, replicating constantly.

I would like to see them continuously improve Zerto's automated functions, such as putting hosts in maintenance mode within vSphere and not having to worry as much about how Zerto is going to react. Rather, Zerto should be able to handle putting various hosts, within either the source or destination side, into maintenance mode without having to worry about the vRA appliances. Sometimes, Zerto almost holds the vSphere environment hostage when it comes to taking certain actions. You really need to be cognizant about what you're about to do. They should further automate that and increase Zerto's ability to handle things like that in a very slick, automated way, without intervention.

Zerto could also build more canned automation tools within their product, tools that automatically work with DNS updates to AWS or Azure. Maybe they could provide an area for scripting help or canned scripts, a community or a place where people could grab some scripting. Maybe they could reach into Citrix or F5 load balancer APIs.

Also, if you have a host go wrong or you need to put one in maintenance in an emergency situation, especially on the source side, it can require you to fix Zerto and redeploy vRAs or redeploy the little appliances to the host that they're going to be on.

Also, depending on what resources it has available, storage or vSphere-wise, I'd like to see it able to balance itself out within the virtual environment, with its storage usage on the destination side.

I've only run into these things briefly, so I can't speak about them at the deepest technical level, but I have noticed that they're not as perfect as they could be.

I have been using Zerto for three months at my current company, but I have about two years' experience with it in total.

For the most part, it has been stable. There have been a few points where I have had to delete the VPG group, re-replicate data, and start over, to get things back to a good spot. But overall it has been pretty stable.

We are only protecting 45 VMs. We're not a large, multinational, so I can't really speak about its scalability.

I haven't used the technical support very much.

We didn't have a previous solution, other than SAN snapshots. That's why we looked to put something in place. Previously, we were in a tenuous situation that would make anyone nervous. We went in this direction so that we wouldn't have to be nervous.

It didn't seem that difficult to set up. 

It took a couple of days, but that didn't include setting up the SAN and the secondary sites and all of the infrastructure around having it work directly. But just the Zerto solution itself did not take very long at all to set up.

Everything that we needed to do to facilitate the use of the solution was more involved and took a month or so. At the time, we also deployed a Veeam solution to do the long-term storage, and that was wrapped up in the same project, so it's hard to give an exact amount of time for the deployment. 

Everyone knows Zerto is a little on the expensive side, but what else is there on the market that does the same thing? It is more expensive per client, for what it does, compared to a backup product like Veeam.

We didn't really go into a full evaluation of other solutions. We took the recommendation of our VAR. They're a company that provides us with help in implementing projects. They recommended going to Zerto, and I had already used Zerto before at another company, so I was comfortable with that recommendation.

Zerto serves a very specific purpose in our environment, which is to fail over the entire environment in an emergency, very quickly. Veeam claims to be able to do that, but I don't think it does it as quickly or efficiently as Zerto.

The main thing is to make sure your network infrastructure is designed properly. Zerto is only going to be as successful as the network infrastructure and the automation that is created around it to help with a failover situation.

In our particular situation, we have a stretch network situation, which means we don't really have to do a lot of the automated scripting that most people might have to do, surrounding re-IP-ing the environment and DNS updates. We're in a unique situation. Because we are a telco, we own our entire network and we have the ability to stretch our network to a location that's a state away. That scenario doesn't apply to a lot of other business situations. Other institutions may not have that luxury, in which case their scripted automation, and how well that is set up, would be critical.

Because we weren't doing backup and DR management before, Zerto has probably increased the amount of staff we need. You don't need staff in place for things that you aren't doing.

HPE bought Nimble and made Nimble not as good. Hopefully, the HPE acquisition won't have a negative effect on Zerto. That's a deep concern among all people who have had to deal with things that HPE bought. They need to keep to the original intention and vision without diluting it within some other HPE product or some other HPE offering. I have no interest in seeing Zerto losing its functionality or having it rebranded as some other problematic HPE solution. We bought this as a purpose-built solution to do exactly what we want and that's the way we would like it to stay.

We use it primarily for backup and recovery of individual servers and databases. We also use it for long-term retention.

It helps us

• achieve our RPOs
• conduct successful DR tests
• provide functionality for some of our key, critical customers.

Fortunately, we haven't gone through an unplanned DR situation, but if we were to go into one Zerto would be the top technology that we would use to recover. We would expect it to function as designed to get everything back to working as normal. Otherwise, obviously, it would be a big problem for our company. Zerto is a critical, core piece of infrastructure for the IT infrastructure team. I estimate it would save us hundreds of thousands of dollars in a DR situation.

In addition, when we need to fail back or move workloads, Zerto decreases the time involved. It's hard to quantify how much time it would save us because we haven't compared it to other DR products. But if we were to use our in-house data protection backup solution or our storage solution, Zerto would save weeks of man-hours when it comes to setup, compared to those other solutions. And it could save minutes in terms of the recovery point objectives.

The instant recovery at DR locations is the most valuable feature. We're required to do periodic DR tests of critical databases, including Oracle and Microsoft SQL. We have recovery point objectives set for specific databases and we need to be able to achieve them. Zerto helps solve that business problem.

Zerto is also pretty simple and straightforward when it comes to ease of use. There were no big surprises.

I would like the ability to monitor the performance of some specific components. Right now we're having an issue with local and remote replications with some of the VPGs. Being able to look at individual VPG performance would be helpful. 

Another thing that would help would be a recommender, or some type of tool that says, "Hey, you're not conforming to best practices." It would do a conformance or compliance check to tell you if your VPGs are set up according to best practices and whether your Zerto clusters are set up optimally. It would see if you have HA enabled and whether your alerting is turned on.

Another area for improvement is alerts. We're getting so much noise right now in the 8.5 version. The problem is that we don't know which are the ones we need to act on. We don't know which ones are severe versus those that are informational or notice or debug. They have told us that when we upgrade to version 9 we'll be able to tune some of the alerts. That type of alert tuning, where we can get just the emergency and error alerts, would be helpful, while not necessarily tuning out the informational or notice or debug alerts. If alerts could be channeled to a syslog server where we could filter and see which alerts are the priority that would be an improvement.

We have a network operation center and for us to operationalize this tool with them, we have to be able to deliver each alert along with an action plan for it. That way they can take the appropriate action if Zerto has some type of error. It would help if the alerts didn't just fall on our storage and data protection team. If we could transfer some knowledge and have other level-one teams look at some of the more basic Zerto alerts and try to resolve them, that would help.

I've known about Zerto for several years but I've been actively using it for the last two months.

The stability is pretty good. I haven't seen the software itself break, or the services stop for unknown reasons. 

We did have an issue with a VPG the other day, where it went belly-up, and we had to rethink and do a bunch of baselines. So some type of health monitor that shows both the servers and the VPGs would be helpful.

I haven't worked with the scaling functionality because we only have it in our two major data centers. But I think it would be pretty straightforward and simple to set up scaling.

Currently we're protecting about one petabyte with Zerto. We have some room to grow still with Zerto.

Much like with any technical support—and this is true whether you're talking about IBM, Microsoft, Dell EMC, or any of the big tech players—their level-two guys are definitely good, if you can get one of them. But the level-one guys seem not to be as good. Zerto was acquired by Hewlett Packard Enterprise and it shows with their level-one guys. They're not as vested in the product. All the level-one people who were vested in the product probably left. So a lot of the level-one guys aren't very technical. 

We oftentimes have to work with our technical account manager to get cases moved up to level two. Once they're there, they seem to get some movement, which is good. And, obviously, their level-two support team in Israel is very good.

Positive

I was not part of the initial installation, but I've heard that some of the initial pieces are straightforward. Where it gets complex is that I don't know if it was set up according to their best practices.

The pricing follows normal industry standards.

In a previous company, I was involved in the evaluation process that ended with choosing to go with Zerto.

Zerto sits on top of a lot of other technologies. It's like a "Layer 3" for lack of a better term. Some of the other solutions that are "Layer 2" can be more attractive, solutions like Commvault, Rubrik, and Cohesity. They're able to do more native operations at the OS level, like replication. They have more hooks into the operating system to enable you to do that.

However, Zerto's user interface is good. It's simple, it's straightforward, and it gives you the RPOs and RTOs right then and there. It requires some administration from the VPG perspective, but it's able to bridge a lot of gaps.

My advice would be to work with your Zerto technical account manager for the setup and best practices.

Zerto is good when it comes to continuous data protection. We're currently in the middle of some technical support cases with them, cases that I'm watching, regarding some of our larger databases. But so far, there have been no issues with the smaller databases. It's doing its job.

We haven't yet enabled Zerto to do DR in the cloud, but that's something we are pursuing currently. We have had a demo of it but we haven't done a PoC.

We're replicating mainly some of our critical applications. One is our backup solution and then also some critical applications that we don't want to have to recover from tapes. That's been working very well for us. We actually just recently went through a DR rehearsal, where we ran a quick test and that ran for about a week and then completed that test. Then we were able to report that we were able to successfully recover our critical ERP system inside of the remote location successfully.

I don't have to worry about Zerto so much. It definitely continues working. We definitely have monitoring and everything like this to make sure things are working just fine, but I can't complain about it in any kind of way. I know we are a little behind on the version that we're using and we need to be on the latest and greatest. Right now we're on version 7.0.

It reduced the backup recovery time of our main backup solution by several hours. It's reduced our time because before we have to build a system and restore the data, we install the application and restore the data that took us at least a good 24 hours to do that. And now it's really minutes for us to recover our backup solution.

Zerto reduced the number of staff involved in data recovery or in a data recovery situation. It's now only one person while it was four previously. 

Comparing it to VMware SRM, Zerto is by far the best that I've used before for providing continuous data protection. 

Different parts of the company use VMware, we use Zerto, and then we saw where they were taking us. Ours really takes less than an hour just to do a quick failover. So it didn't make any sense to go with VMware one, so we ended up going with Zerto.

An employee had actually introduced us to it and we looked at it and wanted to try it. He was working for a bank that does quite a bit as far as doing disaster recovery. So if a bank used it then I would definitely use it. 

It is fairly easy. It's not as technical to get around it or anything like that.

It's a fairly easy tool to use. 

I know that Zerto can definitely improve some functionalities. I know some of the cloud pieces probably enable that. At the moment, it's doing what we want for us, and what it's doing for us right now is plenty. I can't say there's any improvement that I can see that needs to be done at the moment.

I'm not sure if it has throttling, meaning, what's going over the wire and how we can throttle that to reduce the amount of data that's going across the bandwidth. I can't remember if that's something that's in this product. It might be in the more recent version. 

I have been using Zerto for three to four years. 

Their support has been very good. I can't complain about them. 

The initial deployment was straightforward for the admin that deployed it. It was not complicated. That person left and then another person came in who didn't know anything about this product and he picked it up fairly easily and he's able to manage it with ease.

He's a VMware administrator and he also maintains Zerto.

The deployment was done within a day.  

We don't have plans to increase usage because we are at the point where we're closing out. We're migrating some of our data centers and right now I know it's going to continue utilizing what we have. We haven't even hit the capacity of what we've got right now. Because I think the license we have is around 75 servers. We haven't even hit that. The only thing that's stopping us from right now is just that we need to increase the storage at the remote location to handle additional workloads. We have around 14 servers. 

We have seen ROI from Zerto. 

It has reduced downtime. It went from 24 hours to four minutes. It could even be seconds. It's fairly quick.

The dollar amount would equate to something in the millions. For an environment to be restored it means restoring our ERP systems. Then in that ERP in that system, it also has some manufacturing as well.

Pricing is fair. I don't see a big issue with the pricing for what we are trying to do. The things that we're replicating, if it were to go down it pays for it in itself there.

We don't have any plans for long-term retention. They talked to us about it. But at the moment it's not in our forecast to look at that.

We don't have to failback because we just fail to a bubble, in other words. We don't want to bring down production because we're going through migration of our ERP. So we fail it over into this bubble. And that's what we're using. It is the test failover that we're using in that environment. Then in that environment, everything is isolated. That's how we use it today. We have never had to failback back to our main site.

I would rate it a nine out of ten. 

Our primary use case is disaster recovery.

We have Zerto deployed on-premises at both our primary and DR locations.

In general, Zerto helps us with our DR plan because it makes things so easy.

Zerto does a very good job of providing continuous data protection. I've been very impressed and would rate it an eight out of ten. Especially when it comes to DR testing, it is very easy to work with and we are able to recover our infrastructure at our DR site within a matter of minutes.

When we have to failback or move workloads, Zerto decreases the time it takes and the number of people involved in the process. I've used other solutions and I haven't seen anything that compares to what it can do. It is difficult to estimate the exact time saving because it depends on the workload.

Realistically, you could have a single admin responsible for the restores, whereas with other solutions, depending on how big your environment is, it would take more people. In our environment, it would take upwards of five people to restore our core infrastructure and by using Zerto, it reduces the number of people by about half.

With respect to DR management, Zerto has reduced the number of people involved in the process. I wasn't at the company when they used the previous product, so I'm not sure by exactly how much.

The most valuable feature is real-time replication, where we have the ability to recover things in near real-time.

It's very helpful for DR testing because we can recover VMs in an isolated bubble and prove our DR methodology.

Zerto is very easy to use, which is one of its big selling points. It takes just a few clicks to restore a VM, which means that it's easy to train somebody to help in a DR situation.

We have had some issues with trying to get certain parts of the backup or restore functionality to work. However, I cannot recall the specific details.

I have been using Zerto since I started with the company two years ago. In total, the company has been using it for approximately four years.

The stability has been very good. I can't think of a time that we've really had any issues that we didn't cause or something maybe with an update. We're running it 24/7 and I can't think of a time that we've had any major issues with it.

From my perspective, Zerto's scalability is very good. We have 60 VPGs and 122 virtual machines that we're using Zerto to replicate to our disaster recovery site. This will grow with any new infrastructure that we build. Any new servers, depending on their RTO or how soon we need to recover them, would be put into Zerto. Potentially, we will add some, although I'm not aware of any major growth at this time.

Our operations department monitors the dashboard just to confirm that our RTO and the VPG health look good. There are perhaps five people in that team, who are watching the dashboard.

In my team, there are three of us that use it, although we don't look at it daily. It would only be if we get reports of an issue or we need to adjust a setting or something like that.

Overall, on a day-to-day basis, there are probably about five people that use it.

I have not personally dealt with the technical support but I know about the experience that my coworker has had. They are typically very helpful and provide good responses compared to other companies in the industry.

Zerto was recently acquired by HP and there is some concern in our organization about what might happen to the technical support, seeing as they were bought out by a bigger company. We're hoping that it doesn't negatively impact the support that we receive.

I have used Veeam in the past and it's similar to Zerto in certain aspects. They both have their pros and cons, but I would say from what I've seen, I like Zerto. It just seems to be a little bit more user-friendly in the UI. Functionality-wise, they're similar. I think Veeam would be one of their main competitors.

I have also used the older product by VMware called Site Replication Manager. It really doesn't compare to Zerto.

I have been involved in some of the Zerto setups and from what I have seen, they go very well. It seems that it is pretty easy to perform the initial setup.

It takes about an hour per site, or per server to upgrade it. 

We deploy and upgrade the solution in-house.

It's usually two people that are responsible for maintenance but it could be four people on the team.

I believe that we have seen a return on our investment. The return comes from time saved in manpower, for example. From what I've seen, it's worth the cost.

I've also heard comments from my coworkers to say that it's an expensive product but it definitely makes you feel more comfortable in a DR situation.

I have not been directly involved in the pricing and licensing. My understanding is that it's expensive but worth the price.

We don't use Zerto for long-term data retention and I'm not aware that there are any plans to do so. We use Zerto in tandem with our backup solution, just to be safe. That said, we have used Zerto for recovery in scenarios where we couldn't find the particular data that we were looking for in our other backup solution. 

We have not experienced any ransomware incidents or other situations where we needed disaster recovery. However, Zerto would definitely save us time for that. Depending on the situation, it could save the number of people involved as well.

Although we have not had to use it in an actual event, it helps us in terms of regulatory and audit compliance. If we had a real event, we would all feel more comfortable that we'd be able to restore or be in a better position to have our infrastructure restored in a small amount of time.

We have not yet looked into using Zerto for DR in the cloud but in the future, we're going to look at the option of doing so.

My advice for anybody who is considering Zerto is to do a proof of concept or a trial. I'm not sure what the vendor has available in this regard but I would advise trying it out with a small number of virtual machines.

I would rate this solution a nine out of ten.

Zerto runs on a Windows Virtual Server and we have it installed at two sites. There is the production site, as well as the failover DR site.

We use this product almost exclusively for disaster recovery. It is responsible for the automated recovery of what we deem to be our mission-critical servers.

In terms of its ability to provide continuous data protection, this is a product that I trust. We test it quarterly to make sure that what the dashboard is telling us is correct. But, I've used it long enough to know that when I see the dashboard telling me that the virtual protection groups (VPGs) health are all green, then things are working correctly. Our average RPO is usually somewhere between three and 10 seconds.

We used to perform a disaster recovery test once a year, and it was painful because everything was manual. Now that we do it quarterly, we're able to provide management with reports of the tests, which not only makes management happy but also makes various governing bodies happy. We're a financial advisory firm, so it's the SEC that oversees us. That said, I'm sure this holds true in many industries. It allows you to have the reports to prove that you've done the tests. We don't have to ask them to take our word for it.

When we need to failback or move workloads, Zerto has absolutely decreased the time and number of people that are required to do so. For example, if I just want to test and prove that the network is up, it's something that I can do by myself. If I want to have people log in and test applications and stuff like that, I would need additional people. However, it has a built-in test function, so it will create a complete test network that you can run workloads on to show that the tests are successful. Afterward, you can delete the network and you're back just running, waiting for the next time you want to do that. In a situation like this, using Zerto saves eight hours or more and I can set it up and test it on my own unless I want people actually testing applications.

Thankfully, we have not had to use this product to recover from a ransomware attack or other disaster, but it would absolutely work in that case. By replicating the data, if ransomware were to hit the production side, it most likely would not also lock the disaster recovery side. This means that we would certainly be able to bring it up from there. Alternatively, it lets us pick points in time, so we can just go back to the moment in time before the ransomware happened. In a situation like this, I can't say that it would take fewer people but it would take fewer hours.

The most valuable feature is the automated failover, as it allows us to get the essential servers up at our DR site with little intervention.

Zerto is extremely easy to use. You set it and forget it.

It has a nice graphical interface.

The reporting could be improved in terms of the reports that you can show to auditors to prove that you have done the testing. I provide the reports that it generates now but, it would be great if, at the end of a DR test, it would generate a report of everything that Zerto did.

This would include details like what systems were up. Currently, that's not how the report reads. You would have to be an IT person to read the current reports that it produces. I would like for them to be the type of reports that I can put in front of an auditor or the president of our firm that would make sense to them, without me having to interpret and explain the results.

We are in our seventh year of using Zerto.

Stability-wise, this solution is rock-solid. If it fails, it's not going to be Zerto that fails. It's going to be either that your storage has failed or the bandwidth, or connectivity, is not there. I don't see a way where Zerto would be the culprit in a failure-type instance.

Our company is fairly small and the entire firm relies on it. That said, only one person actively uses it. We have three or four IT staff but Zerto has always been my responsibility.

In terms of scalability, I bet it would be no issue whatsoever. It's licensed according to the virtual machines that you want to protect. The only limitation of the scalability would be how deep your pockets are because it's going to be license costs.

We're a registered financial advisory firm, and we are growing. In the past year to 18 months, we have grown from approximately 52 employees to 70 employees. Everybody relies on it because if we have a disaster recovery type of situation, then everybody is going to expect to be able to work.

It is still a very small number of IT staff, so I can see that as we hire more IT staff to support a larger user base, we will certainly have more users.  At least, I hope not to be the only one responsible for this solution as we grow.

I would rate the technical support a ten out of ten.

Prior to Zerto, we used VMware Site Recovery Manager (SRM). We switched because it requires a lot of manual upkeep, and there is no automation involved unless you write the scripts. There are lots of freeware sites where you can download scripts, but aside from that, we were spending a lot of time manually writing scripts and maintaining everything. This was really counterproductive for the amount of time we had available in a day.

Essentially, SRM was replaced because of better interface automation and ease of use. 

The setup is very easily done because you tie it into your VMware vCenter. When you put in your credentials, it will recognize everything on your networks. It will recognize storage, whether it be cloud-based or as in our case, at another data center. Once you have those defined, it's just a matter of creating groups that you want to recover, server-wise.

The reason that you would want to do it in groups is that you can set it up in the automation such that it will bring up groups in a certain order. That way, you have a network where the domain controllers come up in the first group, and you can automate stuff from there.

Seven years ago, when I first started to use it, I found it more difficult. I wouldn't say that it was complex but they have certainly made improvements over the years. Where it stands now, if I had to set it up from scratch, I could probably do it in about an hour. Of course, that is because of the way I know the application but in terms of how they have changed the setup, it is certainly more user-friendly than it was compared to where it started.

I remember running into a couple of issues during the deployment, and I contacted their support. They were fantastic and helped me get through it. They made sure that all of my questions were answered, and that it was up and running how we intended it to be used. A lot of it probably had to do with me being a novice at that point, in terms of using the application.

It was a multi-site deployment, with a production site and a DR site, with dedicated storage for each. We have changed the storage that it uses over the years and if I had to do it again, I would use another vendor for storage. A lot of the issues that we ran into were related to the initial storage that we used, as opposed to Zerto issues, even though it was Zerto support that helped me fix them. 

Overall, the deployment was fairly easy. Not because everything went great, but because of the combination of the application being pretty well-written and the support. I would rate the deployment an eight out of ten.

I deployed Zerto with the help of a consultant, contacting support as we needed to. The consultant was NetGain Technologies and they're based out of Lexington, Kentucky. Their service was phenomenal and I would use them again in a heartbeat for this type of deployment. Ultimately, any issues that we ran into boiled down to some issues with the storage we chose to run it on.

I am responsible for the maintenance. 

We have absolutely seen a return on investment in terms of the manhours that have to be put into maintaining and testing this type of product. Thankfully, we have never had to use it in a true DR situation. However, I can guarantee that if something were to happen, even beyond the manhours and ease of automation, that it would pay for itself.

Our network infrastructure runs pretty smoothly most of the time. That said, Zerto has helped us to reduce downtime by approximately 20%. It is difficult to equate this with a monetary value because we have to consider what happens when a client misses a trade or cannot get a hold of their portfolio manager.

If it were an outage of a couple of hours then the person might pay a little more or a little less for a stock that they were trying to purchase. Overall, however, it is difficult to estimate. We aren't a day trading-type firm, so ultimately, I'm not sure that a short outage has any effect on our revenue stream whatsoever.

As a small company, we own the smallest license that Zerto offers, which is 15 VMs. I've not had to contact them or my reseller about purchasing additional licenses or to find out how much they cost.

We spoke with VMware to see what their pipeline was for upgrades or changes to Site Recovery Manager and we also looked at both Cohesity and Rubrik.

I like the separation of the software and the storage, whereas some of those other products are all-in-one. You're buying the software and storage together on the same platform. This means that the scalability would be different.

Sometimes, this is a case of adding shelves for storage. In that situation, for example, you have to start taking the data center rack space into account. Whereas with Zerto, it lets us build upon hardware we already had, even though we use dedicated storage.

Version 9 of this product is out. However, we have not yet upgraded. We're not leveraging the cloud the way a lot of companies do these days, and I know from the release notes that I've read that most of the new features are related to the cloud. There's not a lot of research and development being done on physical data centers anymore.

At this point, I'm very happy with where the product sits for my network. We are now just starting to move things to the cloud, which will take place over the next couple of years, so my assessment in this regard may change in perhaps a few years.

At the moment, we don't have plans to use it for long-term retention. We keep about three days' worth of data in Zerto and then it rolls off. We have other systems in place for long-term retention.

My advice for anybody who is looking into implementing Zerto is to do your homework. In the end, this product checks all of the boxes and it's the one that I would go with.

In the way that we use this solution, which I know is not how everybody uses it, we have storage that is specifically used for Zerto and two data centers. The way it works in that scenario, as long the bandwidth is there, meaning some sort of dedicated circuit between the two sites, it's flawless in my opinion.

The biggest lesson that I have learned from using Zerto is that disaster recovery doesn't have to be a giant pain. I certainly used to look at it that way in the past.

I would rate this solution a ten out of ten.

Our primary use case is for our Tier 1 application environment, we're an SQL environment. We have around 25 VMs that are replicated to a hot site or warm site. And we're a VMware shop and we use Pure Storage as our SAN, but that doesn't matter because Zerto's agnostic. 

We're a small shop. I am the only Zerto user and my official title is Senior Systems Engineer. I handle anything data center-related as far as information stack, the blades, networking, VMware Hypervisor, and Pure Storage. We also have a Citrix environment as well we have to support. I do all of the data center work.

Zerto is a set it and forget it kind of thing. At least it's more of an insurance policy for us. We don't have a good DR plan, but the peace of mind knowing that the data is replicated off-site, like a repository or offsite environment, there is value to that. We just haven't been able to fully embrace the actual testing of the failover and failback process. The testing has worked, but we haven't done a full production failover yet. We've been planning for around a year to do one but it keeps getting pushed back.

Being hardware agnostic is nice in that we don't really need a 15 second recovery time. It's easy to use. It's always doing updates behind the scenes. These are the positive things. The setup is pretty easy. Building out the VPGs is pretty easy. And it works like it's supposed to.

Zerto does what it says it will do when it comes to providing continuous data protection. It gives me all my recovery points up to 15 seconds or less. So if need be, we could recover to that point in time that it says it can do.

Zerto is easy to use for the most part. It's pretty simplistic. The UI is pretty simplistic. There are some things that I'm waiting for newer releases to address some functionality that I'm curious to see has been fixed or not in the new version.

There are still some pieces in testing that aren't automated. There are still some built-in scripts or workflows I wish Zerto would do out-of-the-box, versus having to PowerShell or have a vendor create it, or create it myself. We haven't done a full failback yet of production so I couldn't really say. The failover process is a lot of manual steps, but Zerto is a mechanism that gets the data there. In that aspect, it does what it's supposed to do. But I wish they would expand on their out-of-the-box functionality for the VM. When you fail it over, there are DNS and SQL changes and there are reboots. There are some things I wish that Zerto would facilitate with a checkbox that would do some of these things for me versus having to PowerShell it and put the scripts in a certain place and have support run it. I want it more automated if possible.

The issue I have with ransomware is if I don't know I have ransomware in all my recovery points, and if it goes three months, I wish Zerto somehow either bought a company or could tell me that we're infected with ransomware. If I don't know how ransomware and everything gets encrypted, there's nothing to restore back to if all my recovery points have been corrupted. So I wish Zerto somehow had a mechanism to alert me of suspicious activity.

We have a Trend product that does that for us. We can get alerts of things that Trend finds, but it's always nice to have layers for your security. We have alternatives, but it would be nice if Zerto had a mechanism to alert me as well.

Alerting has also been a pain but it was supposed to be fixed in the newer version and that's. I would like to have more granular alerts.

I have been using Zerto for about four years now. 

When it comes to stability, it does what it says it's going to do. 

I do some babysitting because the alerts are relentless. My biggest pain point is the endless amount of alerts that are just noise. I have to log in and see what actually is an issue because the alerts are just endless. There's not much maintenance I have to do besides logging in and babysitting from time to time.

We keep wanting to test it. It's our main DR strategy, but we just haven't had a window to vet full failover and failback. As far as increasing, I think we're pretty stagnant at the point with what we're backing up with it.

I would rate Zerto support a seven out of ten. 

The initial setup was straightforward. You could deploy the VRAs pretty simplistically as long as you set an IP via the UI, so that was pretty easy. We were up and running in a day.

Our implementation strategy was rushed. We were doing a data center move and we just wanted an extra copy of the data. So this was a stop-gap solution that we stuck with.

We used a reseller for the deployment. They met our expectations. They provide the product, but outside the product, we have to get a stronger resource. If it goes above and beyond like if it's broken, they call Zerto support. If I want some PowerShell scripts and some cool stuff to be done, they need to find a resource. They provide the basic service, which is great. Above and beyond that, they're average or below average.

We pay monthly for the CPU, memory, disk space, the Zerto replication, and then there's a Microsoft charge as well on top of that for the operating system. We pay month to month and we go year to year.

There are additional VM resource costs.

My advice would be to think about the large VMs that you're backing up. Think about the wasted disk space and wasted resources on your production environment, and if you replicate that to a hot or warm site, you have to pay for those resources. The Zerto price is what it is, so you need to work with the business and ensure your Tier 1 or most critical VMs are what you're backing up or want to back up, not just everything. Then scale that to something manageable for replication and find out if you can have minimum resources while replicating and then scale up in a true DR scenario and only pay for the resources as you need them.

It's not really Zerto's fault, but you don't have full visibility on the protected site so you have to rely on your vendor for visibility if an issue arises.

I would advise asking a lot of questions. If you're an SQL environment, make sure you failover all the key components in the correct way. If you want it fully automated, make sure you buy some extra hours to get professional support.

I would rate Zerto an eight out of ten. 

We have two primary use cases. One would be to use it in reaction to a cyber-terror event, particularly ransomware, because Zerto has point-in-time backup. If we find an area that needs to be restored, as long as we figure it out within 24 hours, which is approximately the amount of time we have replicated, we can go back to a point in time. Let's say the files got encrypted at 9:30 AM. We can say restore our 9:29 AM copy of what the data looked like at that point. We have not needed to use that, thankfully, because we've been educating our users very well.

The other case that we would use it for is because we're in a hurricane area. Our particular office is actually in an evacuation area, typically, meaning that we're close enough to the coast that should a hurricane event come through, they generally force us out of the area. What we would do if we needed it, and thankfully we haven't yet, would be to shut down our primary on-prem services to make them a little bit more resistant to water damage. Obviously, if they're not running, they're a little bit less likely to get zapped if there is some water damage. Then we can bring up the copies that we have at our data center and run remotely from that if. It doesn't have a full copy of our entire environment, but it does have a copy of our ERP system, as far as sales are concerned. We wouldn't be able to ship anything, but we could look at orders and help our customers. We could even take orders if we needed to, although we wouldn't be able to process them.

Zerto is a replication solution. It copies our setup which is on-prem to our data center, which is also somewhat local, about 15 miles away. It doesn't really do anything in the cloud other than move data across it. We're not replicating to any cloud-based services like Amazon or Azure. Essentially, we're using it at two on-premises locations: Our primary location, which is what is being replicated, and the replicated copy is being stored at another on-premises location, nearby.

Zerto is purely a business continuity and disaster recovery tool. We don't want to have either one of our primary use case events happen, but if they should happen, it gives us an extra layer of protection. I've got Amazon backups with stuff in completely different regions, but Zerto is more for those two specific scenarios I mentioned. In addition, if somebody deletes a file and it's really important that they have the latest copy of it, Zerto gives us that option. But it really comes down to the ransomware reactions and the hurricane support, because hurricanes are fairly common in this area. The last hurricane event here was before I had Zerto and we had to shut everything down. We really couldn't do much while the hurricane came through. The business wanted something that would give us some protection in that scenario. That's the business continuity aspect. At least we can provide some business capabilities this way. With Zerto, they'll also be able to access a limited functionality version of our system. It definitely provides upper management with a little bit of comfort that we won't be completely down in either a ransomware or a hurricane event.

We're a smaller company. We're owned by a portfolio company, and they're the ones who made a lot of these extra layers of protection happen. Zerto provides me with the comfort of one of those layers. It enables me to make a strong case to my board of directors that, "Yeah, we're good." There's a guy in our board of directors who's something of a tech guy. I can look him in the eye and say, "Hey, we're not bulletproof. We can never be bulletproof, but we're about as close to bulletproof as we can be, especially for a company our size." That's important to the board because they have other companies that aren't as well-protected as we are. I've had conversations with a couple of the guys at those other companies, because they're interested in looking at something like Zerto, and I have been highly recommending it to them. It's a reasonable cost, it provides several layers of protection from ransomware, and if necessary, against natural disasters. I'm very happy to say that Zerto is one of those layers and provides us with very good protection for what it specifically does.

We had two ransomware events prior to being owned by the company that owns us now. Both were events where somebody clicked on a link that they shouldn't have and something ran and encrypted some of our stuff. Now we're much more solidly protected from that, and Zerto is definitely one of the big things protecting us.

If we had to deal with a ransomware event, Zerto would be one of the first things I would use, because it is going to be the fastest to restore data to a certain point. If there were a fire in our building, Zerto would be a big thing too, because we would shut down everything that's in our building. In most cases, Zerto is definitely one of the front lines. It's definitely going to be one of our prevalent DRBC layers of protection.

When you need to fail back or move workloads, Zerto significantly decreases the time it takes. As long as it's one of those scenarios in which we foresee using it, it's great. When we did our two failover tests, it was easy to failover to the other location where we have the replicated copies. The last time we had an actual ransomware event, which was before we had Zerto, it took me 30 hours to restore all the data that I needed to restore. I would imagine Zerto would take 10 to 20 percent of that time.

In terms of saving staff time, I only have three people on my staff, so I'm not going to save human resources by using Zerto. That being said, what it does save me is the trouble of having to use another solution that would take a lot of time. I only engage my guys who work on Zerto for six to 10 hours a year, versus having somebody on staff. That's a significant savings for us, because we don't need somebody on staff who knows how to do things with it. It is pretty easy to use for somebody who's familiar with it and uses it on a regular basis. For example, when I do the upgrade, I'll pay guys to do it because that's what they do.

We have secondary, older equipment where our Zerto backup copy resides. We moved that old hardware to our secondary location and got new stuff in our primary location. Our primary location now copies, via Zerto, to the other location that has our old equipment. It's not quite cloud, but it is in a different location. And it's definitely saving us money in the long-term by not having to pay for cloud storage because we have put it on our older stuff, and it works fine for that scenario.

We did a test turning it back on and rethinking it, and that took a reasonable amount of time. A lot of that is not actually limited by Zerto. It's more limited by your pipeline between your backup location and your primary location. Zerto was very helpful, and it's very easy to use from that standpoint. Once you reconnect the two sites, it does a snapshot check of where it left off and then it copies back over the changes that happened while it was running on your secondary site. That's not automatic. You have to touch it. But it's certainly not super-technical.

Our two primary use cases are Zerto's biggest features for us. That's what we use it for. There may be other situations where it can come in handy, but those are our two primary scenarios.

In terms of providing continuous data protection, Zerto has been great so far. Thankfully, we haven't had an event where we have really needed to rely on it, but we have done a couple of tests prior to hurricane season where we disconnect our primary facility. We then go over to our secondary facility where the replicated data is and we bring everything up and then we do remote access to that location to make sure that it's all working properly. It's very capable. I've also done a couple of test scenarios on ransomware reaction where I'll go in and restore a folder, after hours when nobody is in the system, to emulate a situation where we might need to go back and restore kit encrypted files. So far, it's been great.

Regarding the ease of use, there's a web portal that I use to verify that everything is working well. It has a lot of notifications and it emails me if there's anything going on that's out of the ordinary. For example, if the connection to one of my other sites goes down, it will let me know that it's not able to reach that site. I'm very happy with the way the interface works for my needs, and my tech has been pretty happy with it. Our installation is rather small. We only have 14 servers on it. I'm sure there are other companies that have hundreds, but I imagine that they would see the same capabilities. The web portal is pretty well organized and easy to navigate.

I have been using Zerto for just about three years. We just re-upped the maintenance on it and, until that point, we had a three-year plan for it.

We're on version 7.5, but I've had some discussions with my partner where we have the replication stored. We're doing an upgrade, but we ran out of time before hurricane season so we decided to hold off until after that. We're going to move up to 8.5 as soon as hurricane season is over, but I didn't want to risk getting into a situation where we didn't have Zerto working at all. And version 7.5 has been working fine. There was no real need to do the upgrade, other than to stay current.

We're about a version behind. I generally stay at least a half-a-version behind to let everybody else do all the sorting out of anything that they might find with the new versions, and then I jump on the second-oldest version, once that's a little more mature.

The stability of Zerto itself has been fine. We have some network instability that affects it, but I see the alerts come through and it's not Zerto that is having trouble. Zerto itself is very stable.

Scalability is not really applicable to our situation, but I would imagine that it would be easy to scale if needed. We would just buy additional licenses and strategize a little bit about how we were going to add them.

We only have 15 server licenses, but I expect we'll have some growth as we have a couple of projects upcoming. We're probably going to need another server, so even though we're retiring a few servers, I'll leave the licenses. I won't probably be in any position to make it bigger any time soon, but you never know. Our company always has its eye out for acquisitions. Last year we picked up two companies, although they didn't really result in any major increase in our infrastructure. Maybe we'll pick up somebody similar in size to us and all of a sudden we'll need to protect 10 more servers. I don't have any plans for downsizing Zerto.

If I were to nitpick, I would say that I wish I had a better account manager. Our sales guy has changed a couple of times. I would like a little more responsiveness from our account manager. I've had a couple of issues where getting in touch with him has been a little difficult, and I end up just going around him and dealing with support and support has handled it right away.

I've only had to deal with their tech support a few times, and I would give them a nine out of 10. They've been pretty responsive. They've answered my questions. They've gotten things taken care of.

Before Zerto, I just restored backups. We have Veeam as our primary backup system. Veeam is a traditional backup system. In those ransomware events I mentioned, I literally had to go through and restore a bunch of stuff from different servers from our backup repository, which is onsite. I had to go back and restore this folder and that folder and this folder and that folder. I would sort of have to do that with Zerto, but it would be a lot easier. I could just pick the folder and pick the time, and say, "Go." With Veeam it was definitely a much more complicated process.

We didn't "switch" to Zerto, we added it. We still have our other solution. While there is disaster recovery where you're recovering from a disaster, business continuity is how fast you recover from disaster; how quickly you get the business going again. Zerto reduces our RPOs. It was more a case of added protection and it reduces our recovery times—even though thankfully we've never had to use it—compared to the last time we had to recover.

Zerto came highly recommended from our primary VAR, which is Presidio, the place we bought it from. They said it would do exactly what we needed it to do, and the price was reasonable. I took the recommendation, did some research on them. It's possible I looked at reviews on IT Central Station and someone there said, "Oh yeah, Zerto is great." That's good enough for me. I didn't need to spend a ton of time on it. As long as they've got good reviews from multiple sources, which I did find when I researched Zerto, and it came highly recommended from our VAR, those were two pros and I didn't need to go looking for a con.

I didn't actually set up the software. I had to pay somebody else to do that because it was a little beyond my team's capabilities. Our deployment took about six hours from start to finish. The guy that I worked with said that he was pretty happy with it. He had to send in a couple of help tickets, and they were very responsive and were able to help him get through the issues that he had.

He's from an IT support firm called Creative Network Innovations, and they also have an onsite data center, so they offer data center support services in addition to regular IT support services. In this case, Zerto is data-center related. We use Creative Network Innovations because it's related to what they do for us, and they have people on staff who are comfortable working with it. Even though they don't necessarily do Zerto all the time, they were able to step in, take a look at it, and sort it out for us, so that was good.

I wouldn't necessarily say that they're experts in the software, because they learned it for us. They're not typical Zerto implementers, but that speaks to how easy Zerto is to use. They had never really used it, but they were able to pick it up, plug it in, and get it working for us.

In terms of deployment time, the Zerto piece didn't take long. It was about six hours. What we had to do in terms of setting up networking, that was a little different. The whole project, including Zerto, took about 12 to 16 hours. And when we did our first failover test, that probably took another six hours, because we had to figure out all the nuances of how to make it handle the various servers that we have.

It depends on the size of your installation. Because we're fairly small, it didn't require a lot of involvement. Most of it is Windows-based, so it's not that hard to install and set up. Things like getting access through the VPN, which weren't necessarily Zerto-specific, are what took a little time, but the Zerto piece was pretty fast.

It's a backup piece for us. We didn't really get that fancy. We basically identified the servers we needed to replicate offsite. Then we installed Zerto on our primary location and we installed Zerto on our secondary location. And we created the communication.

In terms of users, I'm the only one in our organization who monitors Zerto, and I do very little of that.

I would estimate that if I had to recover from a scenario like the last one that affected us, it would take me 10 to 20 percent of the time it took me at that time. That reduces the amount of time that our system is down and, therefore, the amount of money we're losing because our system is down. It does provide some cost-benefit, but it's hard to quantify, because nobody has said, "In our company, we lose $X an hour when we're down." But when things are down, people are not happy. If nothing else, it means I hear less griping, and that makes me happier.

They have an enterprise-type of licensing scenario, which we didn't qualify for because we don't have enough. Ours is pretty straightforward. It is site-based, but the payment concepts are based on the number of servers. In our case, we have a quantity of 15. When we bought it, there was an initial purchase amount plus maintenance. When it came up for renewal, we did three more years, and it was under $10,000 for my 15 servers.

It's very reasonably priced. It's a little more than $3,000 annually. That works out to about $20 per server per month.

Our backup recovery software, Veeam, is working on a product that will compete with Zerto. But it's still very new. It has not been out for very long, so I don't anticipate us going away from Zerto any time soon. That being said, when our renewal comes up with Zerto, I might reevaluate and look at Veeam and see if their solution is going to cover what Zerto does, because then I have one vendor to deal with, not that I dislike dealing with Zerto. It's just sometimes it's nicer to put all of your stuff into one package because the interfaces are uniform.

At this point in time, Zerto is safe with us. We've got them for three more years, and it does exactly what we need it to. Is it going to be our daily backup and our long-term retention? At this point in time, no. I'm pretty happy with what Veeam does and how it integrates with VMware, not that Zerto does a poor job. Zerto covers a different area.

It's kind of like if you were wearing armor, as a knight of old, but you were missing a piece on your back. If somebody stabbed you in the back, if you had armor there, you wouldn't worry about it. Zerto covers our "back." It covers stuff that Veeam doesn't. It handles point-in-time backups and it gives us a faster recovery in certain scenarios. It's not going to necessarily protect us from a full on-premises failure, because I don't have it doing that. I bought it specifically to defend us from certain types of attacks. We have Zerto handling 14 servers but we have a total of 20 servers. It's not backing up the other six, Veeam is, but that's because I don't need those to be protected from ransomware. I need them to be protected from system failure or catastrophic disaster where our primary location is under 20 feet of water from a hurricane, or the whole thing burns down. Zerto is not going to protect us from that, although it possibly could. We just don't use it for that.

It provides us some niche protection and we're happy with the niche that it protects.

Because we're a smaller company, I would never need a full-time person to do disaster recovery, whereas a company with several thousand employees and multiple billions of dollars of revenue would probably have a team for that. I would imagine those guys would save people if they had Zerto, but that's just me imagining that, rather than it being fact.

If I had 1,000 servers, it might require more of my time, but we have 14. We have a board of directors that wants things to be bulletproof, and they're willing to pay for it. Do we need Zerto? Probably not. Is it nice to have? For sure. But we certainly don't use it in the typical use environment, which I'm sure is a lot more servers than we have. That being said, we still use it, and I highly recommend it, even for companies of our size, although it's probably not the sweet spot for a lot of companies like ours. It's kind of pricey for smaller companies, but for what it does, I think the value is exceptional.

For companies of our size, if you don't have somebody on staff who can use Zerto, you want to find the right help. Your VMware person should be able to help you with it. Make sure that you're comfortable with what you're trying to accomplish. I thought it was a pretty smooth implementation, as you can tell from the time that it took. That might be in part due to the people we enlisted to help us. I can't say that everybody's installation will go that smoothly, but I would imagine that if you have a pretty solid VMware-type person, you should be pretty good with the Zerto piece. It's really a matter of working on the VMware side of it. There is also a little bit of networking, depending on where you're backing up to.

If you're backing up to the cloud, you obviously need somebody who is cloud-savvy who can get the proper connections to your AWS and secure them.

Overall, make sure you have somebody who is VMware-savvy. You don't necessarily need somebody who is specifically Zerto-savvy. The guys that I worked with said that it was pretty easy to work with, even though they hadn't worked with it before. But again, ours was a smaller installation. A Fortune 500 company is going to need a little bit more capability. They're going to want to look for a Zerto-certified implementer, which I presume there are. We didn't bother with that because we're smaller and we didn't really have anything particularly difficult in our implementation.

In terms of preventing downtime, in our situation Zerto hasn't helped reduce that, but it's not because Zerto is not capable of doing so. It's just that we haven't had a situation like that in which it has needed to be used. We haven't had any incidents that required the use of the Zerto fallback.

The biggest lesson I've learned from using Zerto is that I wish I had known about it six years ago. I wish that I had known about its capabilities. Given that it's on version 8.5, it's been around for a while. I really wish we would have had it when we actually had a need for it.

If we ever need it, we're confident in it, given the test scenarios we've gone through where it's been great. It's a nice "warm blanket," and it's good to "cuddle" underneath it, because I don't have to worry about it. If I have an event, I'm pretty confident that I can get us back up and running quickly. Is it going to be instantaneous? Of course not. But it's going to take significantly less time than it would take if I had to react via a manual backup.

Zerto is "the bomb." I'm definitely happy we got it. Overall, it's reasonably priced. It's one of the less expensive business continuity and disaster recovery layers that we have. That being said, it doesn't do everything. We're a smaller shop. There are only three people on my IT team, including me. It's definitely been a very helpful tool and comforting to know that we have it in place. It makes it easier to sleep at night. For what we need it for, it does everything we need.

Zerto is a nine out of 10 and maybe even close to a 10. It's solid. It's a good product. It does what we need it to do. Since we haven't actually had a live event, I can't say that it's perfect, but in the tests we have run it through it has been great. The only blemish has been dealing with the account manager, which could be situational. I've only had to deal with him a few times. The last time he didn't even respond to me. That being said, it's been three years, and maybe he's moved on and nobody is monitoring his email box. And when I reached out to support, they took care of me right away. So the account management is a minor blemish. Everything else, as far as the product and support go, has been fantabulous.
