HPE Zerto Software Reviews

We utilize Zerto to backup our on-prem environment to our cloud provider. We've also used it for migrations from on-prem to our cloud provider.

Our deployment model is a hybrid. We're using on-prem and also replicating to Azure.

It is used in our production environment and also our lower environment, on-prem. It's like a DR, as we're backing it all up to our cloud provider. There are a handful of servers involved, replicating and backing up.

It saves us about eight to 10 hours a month in staff time.

Another benefit is just the peace of mind that everything is backed up. We rely on the backups, that they're good backups. It's not like we have to second-guess them.

It has also helped us with our migration to our cloud provider. It's made it easier, sped up the process, and taken a lot of the guesswork out of it.

The solution has reduced the number of staff involved in data recovery situations for our backup and recovery side by at least two people.

The most valuable features are 

• the single pane of glass
• the reduction in time it takes for our systems engineering team to manage the platform.

In addition, the RPOs and RTOs are great on it. It keeps up with things. The protection has been perfect so far when we have done our tests of spinning things up every six months or so. All our backups have come up with no issues at all. They just make great replication copies.

Zerto is also easy to use. That single pane of glass makes it very easy to check on the status of replicated items, and if there are any issues, to dig into them to fix them.

So far, it's been pretty good. I haven't had any issues. If I had to pick anything, it would be the documentation for upgrades. They need to make it easier for users to do upgrades without having to contact support, by providing better documentation for that.

We have been using Zerto since 2018.

So far, it's been very stable. We don't have any issue with the services or the ZVAs. They just keep trucking. There have been no stability issues at.

It's very easy to scale with it. As our environment has grown over the years, we've been able to add ZVAs to it, configure them, and they just fall right into the mix. Scaling is very easy.

Technical support has been very helpful and quick to get back with responses. Ticket turnaround time has never taken more than an hour for me to receive a response back to a general question.

We used Avamar. The primary reason we switched to Zerto was the integration with cloud providers that it provides.

I was not involved in the implementation, but I do remember that it was a pretty short implementation time. It included setting up the ZVA agents in our on-prem environment and connecting to our provider's cloud storage. The longest part of the implementation was getting the data, the initial seed or the backups, up there. But that's nothing against Zerto. Every environment will be different on that and has to get its initial copy up there. Since then, keeping copies up to date has been good. It meets up with RPOs and RTOs.

The initial implementation and getting everything set up took us about two and a half weeks. After that, to get everything that we are protecting into the cloud took us close to a month. We had to do it in stages, due to our work environment and our connections at the time. We didn't have the biggest connections, but that's more on our side, not Zerto's.

There are three people involved in maintaining Zerto for us. They're systems engineers.

Zerto is a lot easier to use than Avamar: easier management, easier setup, and the single pane of glass to watch over everything makes it better. I wouldn't say there's really a cost savings. They're probably comparable in price, but there were a lot more features and options with Zerto than in Avamar.

If you want something that's easy to set up, with a single pane of glass, and that doesn't take a backup administrator to admin, Zerto is the way to go.

The only lesson we really learned, and this has been resolved now, is that when we initially started using Zerto there were some hiccups when it came to Linux servers, hiccups that we had to work through. Support was very helpful and resolved it for us, but it made it a little bit of a manual process. In the later releases of Zerto, they've resolved those issues. They just had to work out some kinks.

We use the solution for two different data center sites. Inside the data centers we use VMware virtualization, NSX stretched VLANs and Dell servers. There are many servers, storage, virtualization, and a myriad of operating systems such as Red Hat and Windows Servers. 

We use Zerto to replicate our VMs from one site to the other, where we don't want to have to pay for two licenses of the same thing. We also do this to have high availability or to have the disaster recovery version of a piece of software. It is a benefit to be able to use Zerto to replicate that VM at the second site, and not have to power it on or anything. We know that it's always replicated on the other site. We currently use the solution for disaster recovery only but we are looking at longterm backup retention in the future.

I think it's perfect for providing continuous data protection for us, it is excellent. 

The most valuable feature is how simple it is to implement and how quickly you can get up and running at the second site. The solution is also extremely easy to use, for example, You just log onto the console and you can do a test failover with a few clicks. You can run a failover test for your auditors or your management. Afterwards, you can get a report on how easy it was to failover a specific application and the VMs associated with that application.

In future releases, doing backups of the environment we need to be able to do hot backups of the database. Granular based backups of the OS, versus taking a backup of the entire VMDK. Currently, I don't think we are able to do all that right now. Having an agent-based backup is a benefit because you can back up the OS files, and If you have an agent for the database, you can do a hot backup of the database and restore it. You then would have the ability to do an entire VMDK backup. I don't think that they have the ability to do a hot backup of a database itself via an agent or something similar.

I have been using this solution for four years.

We have a couple hundred people using the solution within the organization. The solution is very stable, you set it up and you can forget it. When we have had issues where we lost the connectivity to a data center, we were easily able to bring up the VMs of a data center that was available using Zerto.

It's very easy to add new hosts and the VRAs get to pull it out automatically. It's very easy to scale, at more sites. We are already increasing and adding more data centers that Zerto can protect for us. We are very pleased with it.

The customer service is stellar. They always answer and they are very helpful. I have had very good relationships with the sales executives and sales engineers. If the team at the technical support cannot get an issue solved, then our pre-sales engineers will get on calls with us and help us sort through problems. They have been great.

We were using SRM, VMware's Site Recovery Manager before we switched to Zerto. We did the switch because we were impressed with the demo that was given to us. Additionally, SRM was very complicated and cumbersome.

The setup was easy and demo replication was simple too. The initial process started by us building out the VMs of the virtual machines, as per their requirements. We deployed the manager, based on all the log information of the vCenter. You then select the data storage and it installs the VRA out on your environment. Once that is done, you put together the virtual protection groups and you build out your replication site, it is very easy.

Our deployment took about a month to go through everything with three different staff members and for the maintenance, we have one technician. Make sure that we grouped everything properly together, based on the network and its functions, and how it should be brought back up etc.

I have saved days and even weeks of working time from using the solution. We are in the process right now of designing a new cloud infrastructure for one of our environments to utilize Zerto to replicate our VMs to our cloud. It is going to be a huge time saver, probably saving us a couple hundred thousand dollars. We've definitely seen some good return on investment with it. Our auditors are impressed by it. 

This solution is far less expensive than SRM and NetBackup. After the standard licencing cost there is an annual support contract, nothing that we were shocked about.

We have also used NetBackup but Zerto was much easier to set up.

When trying to think of improvements I cannot think of anything to critiques at this time because it does behave so amazingly well. I've been involved with other SRM implementations and SRM is very complicated to put together and to configure, whereas Zerto is just so easy out of the box. Overall, the solution probably has saved us hundreds of thousands of dollars or maybe millions.

Some of the important lessons we have learned are you need to plan your DR carefully. That is the most important. Also, make sure that your applications are grouped together, be cognizant of the different virtual networks they go into. For example, If you have a web frontend DMZ that goes into one component, where the application and the database are in another place. You need to be careful on what networks you are sending them to at the replication site, be aware of that.

I highly recommend Zerto. I speak about the product all the time. I think that it is priceless what it does for us. 

I rate Zerto a ten out of ten.

We use Zerto for data migrations. We use it to move our virtual machines from one location or data center to another and eventually, we then switch that over to DR from our facility in one state to another. It's for the migration of existing VMs.

Zerto has improved my organization by allowing us to do several VM moves. It simply allows us to bring a server back up on the new side, which looks like a reboot of a server. It's a virtual move to the new stage, so it goes from existing VM host to new VM host on the other side.

It has reduced downtime for the servers that we migrate over. By how much is a hard number to put because we do a big group of them together, so we're able to group the move as opposed to doing more one-offs.

The amount the downtime would cost my company would strictly depend upon which servers we were moving because some don't really cost the business. There are others that would cost the business for having to be up as much as possible, 24/7.

The Move feature is the most valuable feature because it allows us to move the VM from our old environment to our new environment with minimal disruption.

It's extremely easy to use. It's pretty self-explanatory as you run through setting up your VPGs for your protection groups and then to do a migration or a test failover.

Some of the features need improvement. One would be, as you're creating a Move group or a VPG, as they call it, it should either autosave or have the ability so that you can save it for coming back to later because if the setup times out, you lose all your work. That would be a nice improvement to have.

We have been using Zerto for three months. 

So far, the stability has been great. We have not had any issues with that.

Only two of us work on it and we're both system engineers.

We do not need dedicated staff for deployment and maintenance of the solution.

It's being used to move a total of around a couple of thousand VMs, so I don't have any issues with scalability.

Currently, we aren't planning to expand capacity because we have a total of around 500 agents to protect, so until we get the true DR, we will have to evaluate if we need to expand that. We will primarily only be using it for DR and any server migrations we may need to do from one system to another.

Their technical support has been very good and prompt to get back to us with answers.

We would either use a Veeam or VMware solution, but we haven't had a real DR product outside of Veeam.

We find Zerto to be the most beneficial right now in helping us migrate from one data center to another data center for the testing environment. And for future capabilities, for a true DR scenario.

I would say it's a lot more simple to set up and maintain than VMware and Veeam.

Replacing these legacy solutions has saved us on the costs needed to manage them.

The implementation was really straightforward and easy. We worked with one of their support engineers and we got it up and running really quickly. The deployment took around one hour. 

We didn't really have an implementation strategy. It was about getting the server manager and server up and then walk through the installation steps. We followed their guidelines.

I'm not sure if I can put a dollar amount on ROI but the biggest return is time to actually get things set up and then begin to migrate virtual machines over to the new environment.

I'm not 100% sure about the pricing because I wasn't as much part of the pricing part of it, but it fell within our budget. Its features and price are good compared to the options we were looking at.

We also evaluated Rubrik and a solution from Dell. The main advantage that we found was that Zerto fit our current need for migrating from one environment to another better than others, and its good standing in the community where there are a few products.

My advice would be to plan out your Move groups and work with your business to get everything validated so you can back up on the other side.

I would rate Zerto a nine out of ten. 

We have servers in Houston and we have servers at a DR site, we need to be able to make sure that they're replicated in some form or fashion. That's what we use Zerto for, to replicate between our primary site and our DR site.

The biggest improvement for us was going from a possible 24-hour lag on our backups to real-time lag. With the hurricanes here in Houston, buildings losing power, and so on, it was nice having the ability to just go flip a switch and we're live with current data as opposed to we're live with what happened yesterday.

Zerto has helped to decrease the number of people involved when we need to failback workloads. It's a much smaller number. It's time-consuming because of the way it works, but it's not overly overbearing. Instead of taking a better part of the day or two to get everything up and running, it really only takes us three or four hours. It has also decreased the number of people we need. It would take three or four of us to bring up servers, make sure they're all running, test them, and all that stuff. Now, it takes one person to bring them all up and then there's a couple of us to test it, so we have half or less of what it used to take. 

We've never had a ransomware issue. The reasons for our failover has typically been natural disaster caused.

Pretty much all of the features are valuable. The biggest thing we use it for is replication, so the ability to set up our virtual server, set it to replicate, and Zerto handling everything else is the biggest feature that we like.

The continuous data protection is great. We love it because we can see exactly how many seconds behind real-time we are, which is usually under 10 seconds. It keeps things up to date. We love the product.

We currently don't use it for long-term retention. It's something we may look at in the future, but that's not the product we're using for that.

Zerto is very easy to use once everything's set up, which isn't difficult. It takes a little bit of time to make sure all the network stuff is all set up properly, but once everything's set up, using it day to day is very simple.

Zerto has saved us money by enabling us to do DR in the cloud rather than in a physical data center. Our DR is to a physical data center. We don't put our data in the cloud.

For what we got it for, it does it great. I use a different solution for my disk-to-disk local backups to where I can have a local backup of files. I don't think Zerto does that well to where it keeps a memory of the files that are there. Basically, when something is deleted on Zerto, it gets deleted on the replicated version. So, some sort of snapshotting or something where I could have backups at different points in time of files would be a really helpful tool.

We have been using Zerto for five years. 

Stability is great. The only downtime we have is during upgrades and patches. I really haven't had any problems with the platform or stability.

The time it takes to update or patch depends on the size of the patch. Major upgrades take a little bit longer, but I mean, it's typically a couple of hours at the most. It's not a huge thing.

Scalability has been great. It continues to grow as we grow. I haven't had any problems with it.

Zerto is being used 100% across our environment. 

We've got about 11 servers doing backups in the 20 to 25 terabyte range most of the time.

Only I work with Zerto in my company. 

The two times that we've contacted technical support, we didn't have any problems. They've been helpful. They made sure we got the issue resolved and did very well with it.

We previously used Veeam. We switched because of real-time backups. Veeam was a point-in-time backup. We said, "You're going to back up at this time." It took a snapshot and backed it up. Zerto just continually backs it up and makes sure that we're currently up to date and matching the server at your primary.

We use Zerto primarily for disaster recovery to the DR site. We still use Veeam for our backup disk-to-disk local for file backups.

Once Zerto is set up and running it is much more hands-off. You don't really have to do anything. You just log in to check, make sure everything's going well, and you're pretty much done. With Veeam, I feel like I have to check in a little bit more often, make sure the backups are running properly, making sure all the files are there, and everything like that. There is a little bit more checking to do on a regular basis.

I don't know if we would have failed over with Veeam because of the amount of time it took and coming back online at the primary site. I don't know that we would have failed over, which would have been probably five or six days of downtime. If we had failed over, we'd probably have lost two or three days in one direction, and probably another two or three days coming back to the primary.

The initial setup was pretty straightforward. It took a little while to make sure we had everything connected right, and that it was going to the right place, but it's no more difficult than any other setup for something like this. I didn't find it difficult at all.

If you don't include seeding and you only include the setup and deployment, it only took us a day or two of planning and then another day of actually implementing it. The seeding took a while, but that's to be expected.

In terms of our implementation strategy, we were using a different product back then, which wasn't as up to date and live. We were just backing up at night, so we had a nightly snapshot that was being transferred to our DR site. Our strategy with Zerto was to get us to more of a real-time backup solution at the DR site and make sure everything was good. That was the entire purpose of going with Zerto.

We used a third-party integrator for the deployment. We used Centre Technologies and they were great. We've used them for other stuff and we didn't have any problems with it and never have.

The one time we had the failover and run at the DR site, instead of having two or three days of downtime, we really had less than one day of downtime. If you measure that in how much money we were able to make that day, it's around $200,000 to $300,000.

We are on the lowest license because we don't exceed the number of servers for the base license, so I don't have a lot of information about licensing. The price of it was comparable, if not better than what we were paying for Veeam. I have no problem with the pricing at all.

There are no additional costs to the standard licensing. 

Make sure you know how long it's going to take to do your initial seeding. If you've got a lot of data, and you're doing it over a pretty good distance, just make sure your pipe is big enough for the initial seeding. Once the seeding's done, pipe size doesn't matter, but the initial seeding can take a good amount of time over a small-ish pipe if you're replicating a lot of data.

For our largest servers to seed can take a full week or to 10 days for one server, for our large file server to seed is about seven terabytes, but we don't have a huge pipe at our DR site. We negotiated to increase the pipe size temporarily while we were doing the seeding, and that reduced the time drastically on how long it took to seed. I can't really give a number or what to look for. I would just have that conversation with Zerto about how long a certain pipe is going to take. How long is it going to take to seed using whatever pipe size based on the amount of data that they have.

Make sure all of your notifications are set up well when it fails. It takes a little tweaking and making sure that everything is set up right, but when you want to make sure you're notified if you get outside your SLA on how long the backups are trailing, making sure all that's set up properly is key.

I would rate Zerto a nine out of ten. 

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.

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. 

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.

I have been using Zerto for around three years. 

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.

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. 

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.

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.

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. 

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.

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

We also evaluated Veeam.

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.

We're backing up VMs with it. Our company has about 200 VMs and we're using Zerto on 30 of them in the main line of business applications. We're using it to replicate all that data over to our DR site so we can do our testing and reporting against that. 

Within those 30 servers we've broken out into three different SLAs on which ones get spun up first. We have it all scripted with monthly plans to fail over, spin it up, actually use it over there, spin it down, bring it back into production, etc.

The business that we're in means we have to run our network 365 days, 24/7, with no downtime. If there's any kind of interruption to business processes — power outage, tornado, fire, etc. — we need to be able to get certain systems up and going in almost real-time. That's how we're leveraging Zerto, to guarantee that uptime and for the ability to spin these things up near-instantaneously.

I know my networking team loves the tool and the interface and being able to roll back and do the failover stuff very easily. But for me, personally, it's how it has impacted our business. The reporting functionality showing that our DR plan is rock-solid and stable, and my ability to generate summaries for our customers, have really improved business processes for us. It gives peace of mind to our customers that our systems are stable and the services that we're providing are stable.

Also, when we need to failback or move workloads, Zerto decreases the time it takes and the number of people involved. The failback feature, from a technical standpoint, is what sold us on Zerto. One of the challenges we had with Site Recovery Manager was spinning up and being in production at DR. If everything is equal, everything is patched and everything's working, both solutions offer a very similar experience: the ability to move a workload from production to disaster recovery works with both of them, no problem. Coming back the other way was just a bear of a move with Site Recovery Manager. With Zerto, it's almost seamless. With Zerto, it takes about four or five mouse clicks and stuff fails back over, and our end-users are none the wiser. And it's just one guy doing it. When failing back from Site Recovery Manager, we'd have to get one of our sys admins involved and we'd have to let our end-users know that they all had to log out.

While it hasn't reduced staff, we have become more efficient and it has allowed me to reprioritize some projects. It's freed up some capacity, for sure. We haven't reduced headcount, but it has definitely taken a big wedge out of the daily grind of our backup and recovery; the stuff they always had to check.

Personally, what I find valuable is the executive summary that says our DR plan is operational. I can then pass that out to our customers. 

Per Mar has about 75,000 customers and, more and more these days, especially given all this [COVID] pandemic, we're asked: Do you have a business continuity plan? Is it tested regularly? Do you have documentation for it? Two years ago, a simple email from me saying, "Yes, we have this," sufficed. We're finding now that people want true documentation from an independent system that generates a report. The reporting that comes out of Zerto is a lifesaver for me. I'm able to generate that up, send it out to the customers that need it, and say, "Yes. Here are our SLAs. Here is our monthly test routine. Here is where it shows us being successful," and so forth.

We are doing continuous data protection. It works flawlessly. Our recovery points are measured in seconds. We have all these "baby snapshots" throughout the course of the day, so we can roll a VM back to any point in time, spin it up, and away we go. We're actively using that. It works great.

It's easy to use and there isn't a huge learning curve. Even some of the advanced features are very intuitive to folks who have been in this space before. If you have any kind of skill sets around any kind of backup and recovery tool, the user interface for Zerto is very natural.

One thing I would like to see, and I know that this is on their roadmap, is the ability to use long-term storage in the cloud, like in Azure or AWS, making that even more seamless. Whether it's stored in glacier or on-prem, being able to retrieve that data in a quick manner would be helpful. They're just not there yet.

I've been using Zerto for about a year.

It just works. We architected it pretty nicely. One of our licensed servers is a complete test solution for us to show that it is truly working. We're able to take a small test server, a Dev server is really what it is, and we can move from production, move it over to DR, have it run over there for a day, and then we move it back with no data loss. 

It's never not worked and when you come from the SRM world, that's just unheard of. Now we're a year into this product and have gone through an upgrade, and our June test went off without a hitch. It's very rock-solid.

Their tech support has been fantastic to work with. We ran into a glitch when we did our update in mid-May and our primary data center stopped talking to our secondary data center. We couldn't figure it out. We got their tech support involved right away. They identified a bug right away. They were able to roll us back and then stayed engaged with us as they figured out how to fix the bug. And once the bug was isolated and fixed, they got right back a hold of us to say, "We're ready to go," and then they walked us through upgrading both sides. There was a lot of hand-holding in that upgrade scenario. It was a fantastic experience.

It took them four or five days to fix the bug and they stayed engaged with us just about every single day, letting us know the status of it and when it went to QA. We didn't fall into a black hole. It was a very customer-centric experience.

We were using VMware Site Recovery Manager. We're still a VMware shop. Zerto replaced SRM. It was probably cost-agnostic, but what it really came down to was that SRM breaks all the time. You apply some patches or a Windows update. Uptime and reliability for us are super-critical. We don't have a ton of time to spend on making sure it's always working. We were really looking for a solution that we could architect, deploy, and just let it run, knowing that we're protected without our always having to go back and mess around with it.

What we kept finding with Site Recovery Manager was that every time we wanted to do a full-scale, failover DR test, we would have to spend a week ahead of time prepping for it, to make sure everything would work flawlessly during our test. It always worked, we knew how to patch it and get around it. But disaster doesn't give you a two-week notice. You don't know you're going to have a tornado in two weeks. You get about a 10-minute notice and then you've got cows flying through the air. We wanted a tool that we know would just run and work and be reliable. 

It was cost-neutral to the budget, the timing was right, and the solution was rock-solid so we made the change.

Ease of use and deployment are fantastic. This is a solution that we started with a proof of concept. We threw it in a lab and said, "Hey, let's just see what it looks like." Next thing you know, we never even had to tear down the proof of concept. Once we started seeing it working we said, "This is definitely something that we want." All we really ended up doing was negotiating licenses, applying the license key, and we were off to the races.

Soup to nuts, it took us five hours to spin the whole solution up and to create our protection groups. It was very fast. That includes downloading the software, spinning the VM up, and protecting and backing up data.

We worked with one of their engineers through the proof of concept. Once we said, "Hey, this is going to work," we tested it on a few servers and then we became a paying customer. They worked with us to help us define what made sense for the 30 licenses that we bought and what machines to deploy it to. But it's really not a complicated tool to deploy. There wasn't a ton of architecting and solution-building around it. There was some, but it was a very simple solution to install.

We have seen ROI. And even when you cost-compare against Site Recovery Manager, none of these solutions is cheap. But we are folks who need to have uptime and these things have to work. When you start comparing it against Site Recovery Manager, Zerto blows it out of the water, in my opinion.

If it were easier to license, and to scale it out a little bit more economically, that'd be a godsend. At the end of the day, my druthers would be to have all 200 of our servers protected by this platform. But for a company of our size, that stretches our IT budget and it just doesn't make economic sense. I would really love to be able to just apply Zerto to every virtual machine that we spin up, drop it into the right SLA bucket, and just be done with it, knowing that it's protected, soup to nuts. Unfortunately, that's just cost prohibitive.

My advice would definitely be to leverage the number of VMs. It's not a cheap solution by any stretch, but it delivers on its promise. There's definitely value in the investment. With hindsight, I would have gotten a better cost per VM if I was able to buy, say, 100 licenses. It would have been easier for me to put other servers under the protection of Zerto. I wish I would have had that flexibility at the time. Eventually, budgets will open up and I'll be able to go get another 50 or so licenses, but I'll still be paying a higher price, more than if I would have negotiated a higher quantity to begin with.

We took a look at a couple of other solutions. The other ones fell off the table pretty quickly. We're based in Iowa. We have a good account team here in Iowa from Zerto that knew our account from previous relationships. They came around and said, "This is a tool that you guys really need to take a hard look at."

The sales process took about six months. They came in about six months before my renewal with VMware. We had a few conversations and, about two to three months before the renewal, designed a proof of concept to see if it was actually going to work. They came in and did that. My guys were raving about it and I saw some of the reporting out of it. At that point I said, "Okay, done deal." It was cost neutral. When Site Recovery Manager came up, we canceled that portion of the renewal. There wasn't really a need for us to go out to market. I just trusted the account guys. They knew who we were. The tool worked the way they called it. I don't get too picky. If it works, it's good enough for me.

Take a hard look at it. Don't pass it by, don't be scared off by the price. Definitely take them up on the proof of concept. Have the team come in and do that. You'll be pleasantly surprised.

They talk about technology that can just actually do what it promises. I've been doing this for over 20 years and sometimes you get jaded by the fact that people over-promise and under-deliver. Zerto was definitely on the opposite end of that spectrum. The solution went in so easily that I had to do a double-take when my guys were telling me, "Hey, it's already up and running." I said, "It can't be done already." I'm used to complicated deployments. They promised and it does exactly what they said it would do. Don't be so skeptical. Keep an open mind to it and explore the possibilities.

I just sat through ZertoCON. They put a lot of emphasis on long-term retention. It really started putting a question out there as to whether you need a different backup and recovery solution. We use a different partner called Rubrik for backup and recovery. The challenge that we have with Zerto is that we're only protecting 30 VMs, whereas with Rubrik, we're protecting all 200. There's a little bit of a dance between value and return. So we're not using Zerto for long-term storage right now. We're evaluating it. I don't know if it makes economic sense to do so, but we are taking a look at it. And we're not protecting all 200 servers because of cost.

In terms of using the solution for a data recovery situation due to ransomware or other causes, knock on wood, we have not had to use it in that capacity just yet. We have a very mature cyber security posture and we haven't been popped by ransomware in the last year. But it does give me peace of mind that we also have that ability. That's just another layer of our cyber security posture and we know that we're protected against those threats. So there's definitely a peace of mind around that.

The only folks using it are on our IT team, about five or six of us. Five of my guys use it on a regular basis and know how to manage it. I'm the sixth guy. If I ever have to get in there, we're in trouble.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

We use Zerto for disaster recovery of our tier 1 applications from our primary data center to our secondary data center. We have also used Zerto to successfully perform server migrations from one site to another for data center moves and company acquisitions.

Our administrators love the product and it has been proven to be easier to use than VMware SRM which we were using before going with Zerto.

Zerto has given us the peace of mind to know that we have full DR protection for our critical applications.

Zerto is relatively easy to set up and administer.

We were able to create runbooks within Zerto to help with DR failovers, and testing DR failovers is pretty easy as well.

We used to use VMware SRM and it was very cumbersome to add in new virtual machines or storage volumes because they would basically "break" the SRM protection groups that were already out there. With Zerto, it takes on new additions to protection groups much easier and it saves our admins a lot of time having to care and feed it.

The most valuable feature of Zerto is its overall flexibility, where it can be used for standard DR or you can also use it for server migrations, data center consolidations, etc. You can also use it for data protection and physical to virtual migrations as well.

It is kind of a swiss-army knife.

I can't think of any major areas of improvement with Zerto. Make sure that they are building in cloud-friendly features in future releases because a lot of enterprises are starting to move workloads to the cloud and are seriously considering doing DR to the cloud as well. Our company may be moving in that direction also.

I wouldn't mind seeing Zerto sold at a cheaper price point, although the cost is comparable to VMware SRM.

We have been using Zerto for four Years.

Zerto has been rock solid for us in terms of stability.

The scalability of Zerto seems to be ok. This will depend on the size of your environment and how often you need your data replicated for BCP and SLAs.

Zerto customer service has been great so far. No complaints!

We used to use VMware SRM and we switched to Zerto because it is less expensive and easier to administer.

The initial setup of Zerto was very straight forward. The rest of the configuration will be as complex as your environment's DR needs and application stacks are.

We had an engineer from Zerto help us with the installation and initial configuration for thirty days.

It is good to do a full Disaster Recovery plan for your organization and doing a BCP plan as well. You need to figure out how many critical servers and applications you have in your environment so you will know how many Zerto licenses to buy, etc.

We only baked off VMware SRM and Zerto.

It is good to implement a proof of concept of Zerto to test it out. I highly recommend it for data center moves.
