We can bring a virtual machine online in a test environment, make changes, and turn it off again
Pros and Cons
  • "Zerto's continuous data protection is unmatched. It's phenomenal. It's also very easy to use. The menus are self-explanatory. Once you understand the terminology of the product, what the VPGs (Virtual Protected Groups) are, you're able to pretty much do what you want in the product. It's very easy to use."
  • "It took me a little bit of time to get used to Zerto's terminology and to relate it back to how you do a backup traditionally. It was a little different. It took a little while to understand what a VPG is and what it does. That's an area that they could probably improve on a little, making the documentation easier to understand."

What is our primary use case?

Zerto is part of our disaster recovery plan. We have it set up in our main office and in a remote location in another state. We replicate all of our ERP data over to the replication site utilizing Zerto. In case there's a failure or a ransomware attack, or anything that we need to restore back to a point in time, in real time, Zerto covers those scenarios.

How has it helped my organization?

Being able to bring a virtual machine online in a test environment, look at it, make changes and then say, "Okay, we're done," and turn it off again, is pretty helpful for us. It has actually saved us a couple of times.

For example, we had an order that was put in by a customer but the entire order got deleted. There was no history of it and no way of retrieving what was on the order. So we actually spun up our production ERP system on our remote location, utilizing Zerto. We brought it online and restored it to the point of time when we knew the record was there, and made a screenshot of the record with all the line data included. Then we shut it back down. We were able to re-key the order and it worked out great.

With Zerto, our disaster recovery is probably the one piece that we know is reliable and available. The way Zerto works, and the way we are utilizing it as part of our disaster recovery solution, make our disaster recovery plan very easy to explain for us and to our auditors.

In addition, when we need to fail back or move workloads, Zerto decreases the time it takes and the number of people needed. A failback literally takes minutes to do, and one person can do it. We can either put it into production or just say, "Okay, we've got what we need." We'll just end it and go back to our normal production cycle. It's very easy and definitely decreases workload. There are no tapes to dig out or backups to sort through. You just grab the time you want and say, "Hey, put me back into this period and time," and it does it.

What is most valuable?

Zerto's continuous data protection is unmatched. It's phenomenal.

It's also very easy to use. The menus are self-explanatory. Once you understand the terminology of the product, what the VPGs (Virtual Protected Groups) are, you're able to pretty much do what you want in the product. It's very easy to use.

What needs improvement?

It took me a little bit of time to get used to Zerto's terminology and to relate it back to how you do a backup traditionally. It was a little different. It took a little while to understand what a VPG is and what it does. That's an area that they could probably improve on a little, making the documentation easier to understand.

For how long have I used the solution?

I have been using Zerto for two and a half to three years.

What do I think about the stability of the solution?

The stability of Zerto is outstanding. It runs 24/7 and works as described. If there are any issues or any problems arise, we get notifications from Zerto, but that does not happen often. Usually, if there's an issue, it's related to something we've done, or because we need to increase a file size or job log. Other than that, it works the way it's supposed to.

What do I think about the scalability of the solution?

Zerto covers 10 production machines in our environment, which is not a huge scale. We only have one replication site. We could easily add more replications if we wanted to. Zerto has that flexibility. But for us, a one-to-one replication to our Nashville location works perfectly for us.

How are customer service and support?

I have had to call their technical support and they're very responsive. The issue is always resolved. I give them very high marks for their support.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

We didn't have a solution that does what Zerto does.

How was the initial setup?

The initial setup was very simple, very straightforward. Zerto got online with us when we did the initial configuration and gave us easy guidelines to follow. We were able to have it up and running in less than an hour.

We took what Zerto recommended in their deployment guide. We knew the areas we wanted to cover and what we wanted to improve upon. Based on those things, we were able to come up with a nice, easy plan to follow to get it implemented.

When there's an issue, just one person is involved, but generally speaking, there's not much maintenance on Zerto. Once you get it up and running, it does what it's supposed to do.

What was our ROI?

We have definitely seen return on our investment in Zerto. First, it's a time-saver. Second, for IT, it gives us peace of mind. We don't have to worry about it. 

One of the ways Zerto is really good in that regard is that you can actually bring your servers online in your test environment and see exactly what something would look like if you restored it. And if you don't want to restore it, you just hit "cancel" and it puts it back the way it was. It's great to be able to do that. The test features they have built into the product mean you can test a scenario like "What if I want to spin this up over here, how would it look?" You can do that.

What's my experience with pricing, setup cost, and licensing?

Licensing Zerto was very simple. They had a product that fit our size and scale. It made it really easy to choose. 

As far as pricing goes again, we're a $150 million dollar company, meaning we're not a huge company but we're not a small one either. Zerto had the right pricing model that fit our budget, and they delivered on it.

Which other solutions did I evaluate?

Zerto was the leader in the category, and I'd used it in the past with another company, so we just went straight to Zerto. There was no need for a PoC with another product. We knew it would work for us.

What other advice do I have?

My advice about Zerto would be "do it." The product is just that good. What it does is very impressive. And again, it gives you peace of mind, knowing your data is safe and secure and that it's replicating like it's supposed to. That's just a great feeling.

We don't do long-term retention currently due to how our backups are made. We use Zerto for anything less than a one-week window and we can revert back. 

Thankfully, we have not had to use Zerto for ransomware, but it would absolutely be a lifesaver should that scenario come up. Similarly, we haven't had a situation where we had to fully flip over to our DR environment. We have tested it, and it works great. Our recovery time would literally be 20 minutes and we'd be up and running in a brand new location, without missing a single record.

While Zerto hasn't necessarily changed the amount of staff involved in our overall backup and DR management, it has definitely made those tasks very easy. We set it up once and we don't have to worry about it anymore. It runs and does its thing. We don't have to babysit it or watch it or worry about it. It just works. For what we use it for, I don't see an area in which I would say, "Hey, add this feature or make this change." It works as described, right out-of-the-box.

Enables us to bring up a virtual machine almost immediately
Pros and Cons
  • "We selected Zerto because the RPO is extremely low, so you can get that server back up almost immediately. That was a huge thing. Also, the ability to do failover tests, where you can test your environment, but not have it impact your production environment, was huge."
  • "If I have to reboot a virtual machine host, I have issues with Zerto catching up afterward. That's about the only thing I would say needs improvement. Sometimes, when I have to do maintenance, Zerto takes a little bit to catch up. That's understandable."

What is our primary use case?

We protect about 15 virtual machines. We use Zerto to replicate them from our home office in Pennsylvania to our co-lo facility in Arizona. Our main data center is in our Pennsylvania office, but if that office were to go down, we would use this as a DR solution so we could run our company out of Arizona.

How has it helped my organization?

When I started with the company, we didn't have a disaster recovery option. If our office were to have gone down, our company would pretty much have ceased to work. Having implemented Zerto, now we know that if there's a power issue or some kind of facility issue at our home office data center, we can run everything that's protected by Zerto out of Arizona.

What is most valuable?

The most valuable feature is the ability to spin up a copy of a virtual machine which is a complete copy, within minutes.

I also enjoy the Analytics, which is something they added recently. They tell me all about my virtual machines and what kind of data we're pushing back and forth. I've been very impressed with Zerto Analytics.

What needs improvement?

The only time I ever have an issue is because there's a virtual server on each host in our environment. If I have to reboot a virtual machine host, I have issues with Zerto catching up afterward. That's about the only thing I would say needs improvement. Sometimes, when I have to do maintenance, Zerto takes a little bit to catch up. That's understandable.

For how long have I used the solution?

I've been using Zerto for between a year-and-a-half and two years.

What do I think about the stability of the solution?

It's extremely stable. I've never had any real issues with it. When there are issues, it seems to recover eventually, so I don't really have any problems with it.

What do I think about the scalability of the solution?

It's very scalable. As long as you have the licensing, you can add more virtual machines or more VPGs, which are virtual protection groups, to the license. As long as you have the licenses, you can protect the whole environment and add and remove virtual machines from Zerto as you want.

We have 15 virtual protection groups which protect 15 virtual machines at this time. Because of the licensing costs we couldn't go crazy. We have a total of about 60 or 70 virtual machines, but we only needed to protect the critical ones. We're using 12 of those 15 licenses.

We don't have plans to increase usage of Zerto at this point because these are the critical servers. If we add more critical servers that need to be up in case of an outage at our home office, we may add more. But this 15 has covered us.

How are customer service and technical support?

Their technical support is good. Just like any technical support, it's all based on the severity of the case. I've never had any outage cases, so I have never had to sit on the phone or wait for them to get back to me. 

I opened two cases with them and they got back within a reasonable amount of time. Both times, they knew exactly what the problem was and how to fix it, just from the details I left them in the case notes.

They also have a nice option where you can submit a case, or enable remote support, right from the interface. The support's pretty nice because they can actually look at logs, once you give them remote access right into your environment. That's very useful. And they're very knowledgeable.

Which solution did I use previously and why did I switch?

We didn't have a previous solution. We selected Zerto because the RPO is extremely low, so you can get that server back up almost immediately. That was a huge thing.

Also, the ability to do failover tests, where you can test your environment, but not have it impact your production environment, was huge. 

Those two features were the main selling points for us to pick up Zerto.

How was the initial setup?

The initial setup was very straightforward, very easy. We set up a virtual machine at both locations, which are both Windows, and then installed the Zerto software and gave it credentials to connect into our environments. It did the rest for us. Once it was initially set up, we just had to figure out which virtual machines we wanted to protect and which way: did we want it to copy from our data center over to the co-lo, or back to our data center from the co-lo. They walk you through step-by-step with wizards. It's incredibly easy to set up.

Because there's a lot of data initially to sync over, the deployment took about a week in total. The initial setup only took a couple of hours, but then you have to wait for all that replication to sync.

We didn't have an implementation strategy for Zerto. Because we didn't have a previous solution, we didn't have any migration to do. We just paid for the license, got it installed, and rolled with it.

What about the implementation team?

I did it myself.

Technically there are four users who have access to it in our company. I'm the main administrator. The other ones are guest administrators and they have a little less access than I do. But nobody else really logs into it except me, unless there's an issue and I'm not there. But as the main administrator it's really all on me.

What was our ROI?

We have seen return on our investment with Zerto, absolutely. Just to have an option for disaster recovery in case our main data center goes down — which can happen, because we don't have a generator or anything in our home office — is a type of return. Not just IT, but everybody in the company from the C-suite, was happy that we have a disaster recovery option now.

What's my experience with pricing, setup cost, and licensing?

First of all, you should figure out which virtual machines are critical and how many licenses you may need before you start getting prices. You don't need to go crazy if you only have a handful of servers that need licensing. 

Zerto sells licensing in bundles or packages, so I wouldn't go crazy and buy 100 licenses when you only need 30. Figure out what you need before you get your licensing, because it can get expensive.

Which other solutions did I evaluate?

We have Veeam which we use for backup and I know they have replication, so we looked into that, but it just wasn't as feature-rich or as quick to restore or bring up a VM as this was. We hadn't heard about Zerto really until we went to a conference in Philadelphia. They told us about it so we looked into it and it seemed like the best option at the time. We did look at maybe one or two other options, but this was the one that looked like the best option for us.

What other advice do I have?

The biggest lesson from using Zerto is the failover capability and the testing capability. Those are two very useful things. If somebody calls me and they need to test something in a test environment, I can use the test failover copy of Zerto to bring up that virtual machine, or machines, and test things without affecting production. The other thing that is impressive is that you really can bring up a virtual machine almost immediately.

I would definitely give it a 10. I have no problems with it. I'm very happy with it.

Does what it says it will do when it comes to providing continuous data protection
Pros and Cons
  • "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."
  • "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."

What is our primary use case?

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.

How has it helped my organization?

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.

What is most valuable?

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.

What needs improvement?

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.

For how long have I used the solution?

I have been using Zerto for about four years now. 

What do I think about the stability of the solution?

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.

How are customer service and technical support?

I would rate Zerto support a seven out of ten. 

How was the initial setup?

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.

What about the implementation team?

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.

What's my experience with pricing, setup cost, and licensing?

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.

What other advice do I have?

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.

Reduces downtime, is simple, and easy to use
Pros and Cons
  • "In terms of continuous data protection, it's the best product that we've found that does this. It's not snapshot-based. It's continuous, so there are no specific points in time we have to worry about recovering to or from. It's pretty much any time, as long as it's within our replication window."
  • "The backup solution needs to be improved. From our perspective, Veeam and Zerto were competing products. They both do very unique things that they're very good at. For instance, Veeam can do replication well. However, it's really a backup product."

What is our primary use case?

We're using it for site plate replication and fail-over or disaster recovery. We're primarily using it to replicate between the data centers that we own and operate.

How has it helped my organization?

We've had a few disasters where we've had a site go out and we've had outages or hardware failures. However, with a single click, we can have all of the failover and when the other sites come back up, it can auto re-replicate in the reverse direction so there is no extra manpower required. Whereas, normally, we would be spending hours and hours cleaning up from the failover event.

What is most valuable?

We enjoy the simplicity of not only configuring replication but failing over with a single click and then having it automatically reverse replication. We've had other products such as Veeam, and their replication works, however, it's very cumbersome to configure. When you failover, there's a bunch of work you have to do after the fact to reverse the direction and to restore the VM and how it names it and which environment it shows up in.

In terms of continuous data protection, it's the best product that we've found that does this. It's not snapshot-based. It's continuous, so there are no specific points in time we have to worry about recovering to or from. It's pretty much any time, as long as it's within our replication window.

The solution is very easy to use. It's very straightforward. You don't really have to do a lot of reading through the documentation, or things like that. You can basically scroll through the menu and figure it out.

We have not had ransomware, so we haven't had to deal with that, however, we definitely had a disaster recovery issue we had where we had the fail-over site stop unexpectedly. It did save us a bit of data loss, whereas, normally, we would have lost six hours' worth of customer data. In this case, it was seamless. We lost seconds' worth.

The solution has reduced downtime. It has done so a couple of times. There could be some cost savings there. It's just not something we calculate.

What needs improvement?

The backup solution needs to be improved. From our perspective, Veeam and Zerto were competing products. They both do very unique things that they're very good at. For instance, Veeam can do replication well. However, it's really a backup product. Zerto can do backup, and yet it's really a disaster recovery product. It would be great if they could improve upon the backup functionality, or continually improve. We've seen some improvements, however, if they continue improving upon that it may eventually eliminate the need for the other product.

For how long have I used the solution?

I've been using the solution for about three years.

What do I think about the stability of the solution?

The solution is very stable. We haven't had any issues. The only issue we had was a DHCP issue where we didn't static a couple of the DVMs, which is the agent for each ESX host, and we were having a few gaps in replication when the IPs would change, however, we've stacked those and that has resolved that issue.

What do I think about the scalability of the solution?

We find that it's very easily scalable. The resource overhead is very minimal so it's really easy to scale up the environment and the product kind of automates the process for you. You select where you want it, hit install, and it handles it for you.

About five people use the product in our company. We have some system administrators, we have a couple of programmers and we have a DBA.

We have around a quarter of our environment replicated with Zerto. It's mostly our critical infrastructure.

We may possibly increase usage over time.

How are customer service and technical support?

Technical support is good. I'd give it an eight out of ten. They're pretty quick to respond. They are almost always able to resolve my issue. I have no complaints. I only had a couple of support tickets, however, the experience was pretty good.

That said, their web portal is a bit clunky to navigate. For example, putting in a request, knowing where to go, or pulling up documentation or upgrading information wasn't quite as intuitive as it could be.

Which solution did I use previously and why did I switch?

We are still using Veeam mostly for backup tasks. We use Zerto for site recovery.

How was the initial setup?

The initial setup was very straightforward and easy.

The installation was simple. There are lots of guides and information. There are YouTube videos. They had training classes that were free that you can go to and they have a little lab environment. Even without the assistance offered, the way you install it is very straightforward and very simple. Really anybody can run the installer and have an idea of what they're doing right out of the gate without really any training.

Deployment took around a day.

We did have a specific deployment plan and we were able to execute that in about a day. Getting all the sites set up and then the VMs replicated was fast.

We have five people on staff that can handle deployment and maintenance.

What about the implementation team?

We didn't use an integrator or consultant. We just did it ourselves.

What was our ROI?

There's not a direct ROI as it's being used as an insurance policy. The only time it really benefits us is when something bad happens.

What's my experience with pricing, setup cost, and licensing?

It's reasonably affordable. Obviously, cheaper would always be better, however, it's not out of the expected range. We are just paying by VM. It's my understanding there are no extra fees.

Which other solutions did I evaluate?

I can't remember the companies off the top of my head as it's been a few years since we've done it, however, we evaluated five or ten different options that were popular at the time. Some of them were integrated with hardware. Some of them were software only.

In the end, it came down to Zerto due to simplicity. It's very simple and straightforward. It removes all the overhead of management and knowing what is active or what's the standby copy. It handles all of those pieces for you.

What other advice do I have?

We're probably on the latest version or one version behind.

We very lightly use the product for very specific things. We have a couple of things that are very high data rate, very high IO, for which we cannot use traditional snapshot-based technology and we are using that to do a long-term backup.

The solution has not reduced the number of staff involved in data recovery situations. We have maintained exactly what we had. It's simplified it so it's possible to have a reduction, however, we haven't done any reduction from that.

The biggest piece of advice I could give is if you want the best-in-class for failover and replication, as well as ease of management, there is no better product that I've seen so far. Whether hardware or software combinations, this has been the simplest deployment and it just works.

I'd rate the solution at a ten out of ten.

Enables us to achieve our RPOs and to conduct successful DR tests
Pros and Cons
  • "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."
  • "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."

What is our primary use case?

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

How has it helped my organization?

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.

What is most valuable?

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.

What needs improvement?

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.

For how long have I used the solution?

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

What do I think about the stability of the solution?

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.

What do I think about the scalability of the solution?

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.

How are customer service and support?

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.

How would you rate customer service and support?

Positive

How was the initial setup?

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.

What's my experience with pricing, setup cost, and licensing?

The pricing follows normal industry standards.

Which other solutions did I evaluate?

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.

What other advice do I have?

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.

Pros and Cons
  • "The most valuable feature is real-time replication, where we have the ability to recover things in near real-time."
  • "We have had some issues with trying to get certain parts of the backup or restore functionality to work."

What is our primary use case?

Our primary use case is disaster recovery.

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

How has it helped my organization?

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.

What is most valuable?

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.

What needs improvement?

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.

For how long have I used the solution?

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.

What do I think about the stability of the solution?

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.

What do I think about the scalability of the solution?

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.

How are customer service and support?

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.

Which solution did I use previously and why did I switch?

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.

How was the initial setup?

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. 

What about the implementation team?

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.

What was our ROI?

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.

What's my experience with pricing, setup cost, and licensing?

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

What other advice do I have?

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.

Easy to use, enabling us to configure a DR solution for our customers they can use themselves
Pros and Cons
  • "It's also very much faster than any other migration or disaster recovery platform we have. I work with virtualization, mostly on VMware, and I must admit that Zerto is even better than VMware Site Recovery Manager. Zerto compresses the data and it works much faster."

    What is our primary use case?

    We use Zerto as a migration platform from a customer's data center or from their on-premises environment to our data centers. We also use it for disaster recovery.

    How has it helped my organization?

    Zerto has helped to reduce the number of people involved during a data recovery situation in our company. All we have to do is click a few times. We have even configured a DR solution for our customers so that they can do it themselves. We give them access to the Zerto platform, as well as have a small manual of instructions, and they can go do it. It's very simple to use and to deploy and to support. It does not have a very large learning curve.

    For our clients who do DR in the cloud, Zerto has definitely saved them money. We only have a few DR client accounts, but for the ones we do have, there haven't been any failures of Zerto, whenever we do failover tests. It performs well.

    What is most valuable?

    It's a great platform because it's very well built, technically. 

    It's also very much faster than any other migration or disaster recovery platform we have. I work with virtualization, mostly on VMware, and I must admit that Zerto is even better than VMware Site Recovery Manager. Zerto compresses the data and it works much faster. We use it whenever we can, and especially whenever we are on a tight time schedule for closing a project, or we need to bring information or VMs from a client or from another data center. Zerto is very valuable because of its speed.

    And in terms of ease of use, when I started with my current company I didn't even know about Zerto. My first project was a migration from a big customer and I thought, "Wow, this will be a lot of work." It was a little scary because of the pressure to get it done. But Zerto was so easy to use. I like it a lot.

    For how long have I used the solution?

    I've been using Zerto for about 12 months, but the company I work for has been using it for four or five years.

    What do I think about the stability of the solution?

    It's very solid, like a rock. It's very stable.

    Even with the most recent customer that we migrated to our data center, it was really impressive that Zerto kept the levels of performance very consistent. This customer's site was at another data center provider, not one of ours. It was on a very old VMware version, and we were deploying them to the latest, vCenter Server 7. At first I thought, "We will be struggling to bring this customer over," because they were two major versions behind. I didn't think Zerto would be compatible for making this migration happen. But it worked like a charm, and we had no problems regarding Zerto itself. While we had some problems with this migration, they were not related to the technology.

    What do I think about the scalability of the solution?

    It's very scalable. Most of our core usage here is for migrations from our customers' on-premises or data center instances. And about two years ago, we had a very big migration of over 3,000 virtual machines, and Zerto performed really well. That's why we have kept Zerto in our portfolio.

    How are customer service and support?

    Their support is amazing. We have had to open some support cases and they have a very good technical team. They're always referring us to their technical teams if we need to discuss something. Or if we fail to understand some of the concepts, we can reach out to them too. It's more than a commercial relationship. They support us whenever we need help.

    How would you rate customer service and support?

    Positive

    How was the initial setup?

    We do setups of Zerto every week or two weeks, because it's not a single platform. We are a multi-cloud environment and service provider. We deploy it according to project requirements. So we don't have a single Zerto platform. We are always deploying VMs and DRs.

    Zerto is very easy and straightforward to set up. Whenever we want to use Zerto for a migration from an on-premises customer to our data center, we usually create a WAN to WAN link, or a LAN to LAN, or a VPN link between the customer and us. We just deploy the VPNs from our side to the customer site and request access to their environment. We check for special VM configurations. It's pretty straightforward. We don't like telling the customer to do it, even though it's very easy to deploy and configure, because it's part of our service to do this job for them. We also have our own guidelines and policies that we use to configure Zerto for the best migration setup.

    The last deployment I did took me four hours, which included setting up both my side and the customer side, doing the pairing and, later, the VPG's. We migrated over 100 VMs and it took about two days to fully replicate their site to ours. The migration window to do the move was about six hours because they had to change applications. But the move itself took no more than two minutes for every Zerto machine. 

    When I talk to the customers, I tell them that it will be faster than the move window we request. Most of the time set aside for the window is for taking applications offline, because they will often need to reconfigure them. When client data comes from an on-premises site to our data centers, there are usually IP address changes, or we have to update VMware tools, or do something at the Zerto machine level by changing Zerto hardware, such as a network card. The moving itself is pretty straightforward.

    What's my experience with pricing, setup cost, and licensing?

    Because I'm a support engineer, I don't really work directly on the commercial side of things. Whenever I need to request a license for Zerto, someone on our dedicated licensing support team takes care of it. So I don't know if that process is easy or not.

    Zerto works very well as a backup and recovery solution, with frequent recovery points. It's very good. But it's too pricey for us to use it as a backup solution for all of our clients. Not every customer needs recovery points every five seconds.

    What other advice do I have?

    It's a great platform, if you use it as a recovery system and as a migration tool. It's really amazing. It's a very well-developed product and one of the best solutions. In the same way that what makes Microsoft big today is Active Directory, which is an amazing product and one that no other enterprise could do any better, Zerto is the same type of leader in its category and is at the very top, without a doubt.

    Real-time replication of data is a vast improvement in scheduled daily backups
    Pros and Cons
    • "The real-time replication of data is the most valuable feature. It is a vast improvement in scheduled daily backups. Real-time data is streamed to the offsite data center, which allows us to restore our mission-critical applications up to 10 seconds from when the last changes were made in our system. If we enter a sales order or enter any kind of information in our ERP application it is replicated within 10 seconds to the offsite location."
    • "Compared to other products, I would praise the intuitiveness of the product. But I think that can always be improved. The intuitiveness of the graphical user interface, while it is very solid and I don't have issues navigating it. I would say that it can always be improved."

    What is our primary use case?

    We use Zerto for disaster recovery data replication from our headquarters to an offsite data center at another location.

    It has replaced all of my legacy backup solutions.

    What is most valuable?

    The real-time replication of data is the most valuable feature. It is a vast improvement in scheduled daily backups. Real-time data is streamed to the offsite data center, which allows us to restore our mission-critical applications up to 10 seconds from when the last changes were made in our system. If we enter a sales order or enter any kind of information in our ERP application it is replicated within 10 seconds to the offsite location. So if we were to have a disaster, it takes about five seconds right now if I look at it. If we were to have a disaster, we would not only have current data, but we'd also be up and running within hours at our offsite data center, rather than days if we had a tape backup solution.

    We have begun using it for longterm retention. We also replicate our file server. Our file server has archive or historical data that we have to restore occasionally. And restoring from long term retention is applicable to those types of scenarios, versus the streaming of the data, the real-time data. The longterm retention allows us to restore from further back in time. Real-time is more for recent changes to the data, and the longterm retention is for if we have to restore from further back.

    It provides continuous data protection. It has been extremely effective. I've done failover testing, and the data is accurate and current. It works.

    In terms of ease of use, Zerto is very intuitive. The graphical user interface of the application, both for monitoring VPG replication, longterm retention success, the configuration of VPG for longterm retention, and the analytics feature is intuitive and allows you to essentially analyze any changes to your environment. All of that requires some training but is not incredibly complex. It's presented in a very easy to use format. 

    Zerto dramatically decreases the amount of time it takes to do a failover. I can essentially do it all by myself and I'm one person, I don't really need help. It allows me to restore our environment fully in a matter of seconds, literally. I can do that on my own from my desk very easily and with no outside help. 

    What needs improvement?

    Compared to other products, I would praise the intuitiveness of the product. But I think that can always be improved. The intuitiveness of the graphical user interface, while it is very solid and I don't have issues navigating it. I would say that it can always be improved.

    For how long have I used the solution?

    I have been using Zerto for around three years. 

    What do I think about the stability of the solution?

    The stability is very solid. It just runs. It has not crashed or had issues. So long as you stay on top of the versions of the application and you have it installed on reliable hardware, you're going to be just fine.

    What do I think about the scalability of the solution?

    It can scale into the cloud. I know it has that capability, but I have not done that yet.

    It's essentially myself and I have one junior person that uses the application, but it's mostly myself.

    It's used for all of our mission-critical servers. Not every single one of our servers, but probably about a third of our total servers.

    I do not have plans to increase usage. 

    How are customer service and technical support?

    The tech support is top-notch. I have an engineer who I work with on a regular basis that communicates with me anytime there is an issue. He has worked side by side with me on any issues, questions, and implementations that I have wanted to accomplish. They by far go above and beyond more than any of my other vendors and I have quite a few so that says a lot about them.

    Which solution did I use previously and why did I switch?

    We previously used Asigra. We switched because of the cost, limitations, and complexity.

    When we decided to go with Zerto, it was imperative that it provided both backup and DR in one platform. Granted, we didn't take advantage of it for a while but that's entirely my own fault. It was very important to have that functionality.

    How was the initial setup?

    It was initially set up by a third party. But since then, I've had to re-set it up and it was pretty easy. It wasn't very complicated. It was quick. There were instructions that we followed pretty closely and there were no issues, so it was straightforward. There were a handful of steps, but nothing overly complex. The deployment took around 30 to 45 minutes. 

    What was our ROI?

    We haven't had a need to use it in an actual live disaster scenario, but we have that capability, which we did not before. But if we had to use it, it would save us a tremendous amount of money. Tremendous.

    What's my experience with pricing, setup cost, and licensing?

    There are no costs in addition to the standard licensing fees. 

    Which other solutions did I evaluate?

    We also evaluated Veeam.

    What other advice do I have?

    It has not saved us time in data recovery situation due to ransomware just because we thankfully haven't had any issues. I've done some testing and in those types of situations, it would be greatly beneficial. But I have not had any of those situations currently.

    At this time it has not helped to reduce downtime in any situation.

    We don't have it replicated in the cloud at this time so it has not saved use money by enabling us to do DR in the cloud, rather than in a physical data center.

    I would recommend Zerto to anybody considering it. 

    My advice would be to make sure that after implementing the product, go through and accomplish the training labs so you know how to use a product really well, develop a disaster recovery plan in the event that you should need to use the product, and work closely with your Zerto engineer to ensure that the implementation fits your business needs.

    The biggest lesson I have learned is how valuable real-time replication of data can be in the event of a disaster and how valuable that functionality is in the event of a disaster. It has the potential to save the company many days' worth of lost business.

    If I could rate it an 11 (out of 10), I would. But we'll go with 10.

    Which deployment model are you using for this solution?
