Easiest and cheapest way to get near real-time replication
Pros and Cons
  • "We relocated all our virtual machines from Belgium to Budapest, Hungary. I am not sure how we would have done it without Zerto, because we were able to keep the data in sync. We would have needed to have a lot more expensive storage products online at the time that could have kept that replication. From what I have seen from other methods, that would have required a much higher amount of bandwidth as well, then the cost would have been extreme. The mechanisms available to us with a storage space replication would have been more labor-intensive and prone to error. It was much easier and more successful with Zerto than other ways at our disposal."
  • "They had a bug recently that has come up and caused some issues. They currently have a bug in their production versions that prevents their product from functioning in some scenarios, and we have hit a few of those scenarios."

What is our primary use case?

We have typical use cases for it: resilience and disaster recovery. They have some other functionalities that their software can help account for, but we are using its disaster recovery and resilience, which are kind of its core functions.

How has it helped my organization?

I have used it in many scenarios, including a temporary data center move in Europe. I had to move all my resources from Belgium to Budapest, and then back, once our data center was physically moved across town in Belgium. I am not sure how this would have been accomplished without Zerto. 

With Zerto, the move was incredibly easy to do. It was click of a button, wait 10 minutes, and everything is up, then turn on the data center. Once the data center was relocated and rebuilt, click a button, and wait a few minutes, then it now runs back to the original site. It was that easy. The data center move part was obviously the hard part, as it should have been, not keeping the applications going at a secondary site during that time. That was a pretty big success with Zerto and our largest use case for it: a data center move.

We are currently using Zerto with some more modern databases, application servers, and tertiary systems to provide redundancy and resiliency to our crown jewel application. We have been doing a lot of DR testing scenarios, part of which relies on Zerto and part of which are other mechanisms. In general, when we have done our recent testing using the Zerto portions, once we say, "Okay, we are doing this now," it is taking less than three minutes on average for the systems to be fully back online at the new location once we start. That includes booting all the Windows VMs up. The actual VMs were ready to go and functional within 30 seconds. However, some of them are larger Windows machines and those take their time to boot, getting services online and connected to everything. So, the Zerto part was literally under a minute in these test scenarios to clear a total failure and initiate our disaster recovery function.

What is most valuable?

The near real-time replication is probably the biggest value of this solution. There are some other ways to get that done, but this seemed to be the easiest and cheapest way to get near real-time replication. In most instances, our RPO is about five seconds, which is pretty aggressive and not that taxing to achieve with Zerto.

The ease of use is pretty high. It really isn't very complex to use. They did a good job with the UI, and it is fairly obvious where you need to click, what you need to click, and what you are doing. There are good confirmation screens, so you are not going to accidentally take down or move loads that you are not trying to. It is fairly user-friendly, easy to use, and you don't need to read a manual for three weeks to start using it.

What needs improvement?

Previously, our main need for Zerto was actually database cluster servers running fairly old software, SQL 2008 on Microsoft Windows clusters with none of the advanced SQL clustering functionality. Our environment is all virtualized. The way we had to present the storage to our host machines in VMware was via raw device mapping (RDM). Technically, Zerto can do that, but not very well. We have gone to some different methods for our databases, which don't actually use or rely on Zerto because the solution wasn't that functional with RDMs. This is an old, antiquated technology that we are currently moving off of. I can't really blame them, but it definitely is something they thought they could do better than they could in practice.

They had a bug recently that has come up and caused some issues. They currently have a bug in their production versions that prevents their product from functioning in some scenarios, and we have hit a few of those scenarios. Aside from that, when it is not hitting a bug, and if we're not trying to use it for our old-style, old-school databases, it functions incredibly well.

Buyer's Guide

August 2025
Learn what your peers think about HPE Zerto Software. Get advice and tips from experienced pros sharing their opinions. Updated: August 2025.
865,295 professionals have used our research since 2012.

For how long have I used the solution?

I had an early Zerto certification from their first ZertoCON conference. I received a certification from them in May 2016, so I have been using it for at least five years. I would have been one of the initial users at my company, so they have been using Zerto for at least five years.

What do I think about the stability of the solution?

Stability is reasonably good, but I wouldn't say excellent. We have had some odd issues with vRAs, which are little VMs that hang off of every VMware host that we have. Those aren't consistent, but they do occasionally happen. As I referenced earlier, there is a bug in the system right now that can affect my VM recovery. It tries to put too many requests into VMware at once, and VMware will timeout those requests, which causes Zerto to fail. That has not been constant throughout our use of Zerto. It is usually a flawless operation, and that is why I can still say good to very good, even though they currently have a bug. It is very uncommon for them to have anything that affects the platform negatively.

What do I think about the scalability of the solution?

Scalability hasn't seemed to be an issue. We started out with two sites connected in the same city. Now, we are running the connected infrastructure of Zerto on three different continents. Some of those continents have various cities and/or countries involved. That has not given us an issue with scalability at all. It seems to be fairly flexible in adding whatever you need it to do. As long as you have the bandwidth capability and reasonable latency between sites, Zerto seems to work quite well.

10 to 12 people are actively in Zerto, or even know what it is besides a word that an IT guy uses to say, "It is okay." Generally speaking, their titles would be network administrator, network engineer, or senior network engineer. 

For all our sites, most of our IT staff wouldn't be allowed to mess with it. Because if you hit the wrong buttons in Zerto, you can take down an application. So, there is a fairly small list of folks who would be able to get into this. Only a few sites can actually access the management console. They are located in Louisville, Kentucky; Belgium, Budapest, and Melbourne, Australia.

How are customer service and support?

I would rate the technical support as eight out of 10. They know the product very well. I have had a couple misfires at times, but they are pretty good in general.

One of the issues that we had early on was regarding some of the storage functionality, especially regarding RDMs. I had contacts and conferences with the Zerto development staff, whom I believe are in Israel, about the ability to ignore disks in Zerto for my virtual protection groups (VPGs). What they can do currently is mark them as temporary disks, then they will do a one-time copy, and that is it. However, some of those temporary disks are extremely large, so it wasn't a great answer for us. I would like the ability to ignore disks instead of still trying to replicate every disk on a VM as being protected by Zerto. The biggest thing that they can do right now is improve their product. This would have been much better a few years ago rather than now. Now, we are finding other ways around it.

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

We previously had some storage-based replication, which we are currently still using, but nothing that really fits the same mold that Zerto does.

Zerto's database storage replication is not good with RDMs. We are still doing storage-based replication for those. 

Our new schematic is self-replicating. It doesn't require any type of Zerto replication or storage-based replication, so that was a need removed.

How was the initial setup?

It was quite straightforward. You just install the software, point it to your vCenter instance, and then deploy your vRAs, which is done automatically. Updates have been the same, e.g., quite straightforward. The only challenge with updates is if you have multiple Zerto instances that are linked to each other. To be able to replicate to different sites, they can't be out more than a half a version. For instance, I am running version 8.5 on all my sites that are currently running Zerto, but I couldn't be running those if I was running 7.5 anywhere. That would have been too far out of appliance. That is more of a minor challenge than a problem. I don't consider that to be a shortcoming, but it is well-documented, easy to figure out, and also pretty straightforward.

The first site was also kind of a learning experience. That deployment took less than a day from, "Okay, let's start the download," to, "Look, it's doing something," and you need to stand up two sites to go from site A to site B. That took less than a day to get them up and functional in at least some capacity, protecting some machines and workloads.

What about the implementation team?

We generally try to perform all functions in-house instead of bringing in a third-party or contractor service to help for deployments. That was the model that we followed. We read the documentation, had Zerto's number handy in case we ran into issues, and deployed it ourselves.

There are probably only five of us (out of the 12 who have access) needed for deployment maintenance. Their titles would be network administrator, network engineer, or senior network engineer. 

It is fairly simple to deploy and maintain. We do product upgrades every six to 12 months.

What was our ROI?

We relocated all our virtual machines from Belgium to Budapest, Hungary. I am not sure how we would have done it without Zerto, because we were able to keep the data in sync. We would have needed to have a lot more expensive storage products online at the time that could have kept that replication. From what I have seen from other methods, that would have required a much higher amount of bandwidth as well, then the cost would have been extreme. The mechanisms available to us with a storage space replication would have been more labor-intensive and prone to error. It was much easier and more successful with Zerto than other ways at our disposal.

Zerto has reduced the time involved that staff would spend on a data recovery operation. We don't have dedicated resources for disaster recovery. It is a scenario where, "Everybody, stop what you are doing. This is what we are all working on right now." We haven't had a reduction in headcount because of Zerto, but we have reduced the use of existing headcount.

DR management is less time-intensive and resource intensive. Therefore, there are less staff hours involved because of Zerto, but not less headcount.

Zerto has helped to reduce downtime in any situation. The easiest one to point out was the data center move. It took minutes to move an application to a different country, then minutes once again to move it back. That would have been hours at best to days with the other solutions that we had at our disposal.

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

Even though we are on-prem, the licensing model was changed to more of a cloud licensing model. We pay for blocks of protected machines. You need to buy a block for use and pay for maintenance annually based on the block size that you have.

When they changed their licensing model, pricing might have gotten a little more expensive for some use cases, but it has been pretty straightforward.

Which other solutions did I evaluate?

It is a little easier to use than Cohesity or Rubrik, but we haven't really had another DR platform in place. 

At the time of evaluation, we did not have a good snapshot-based backup platform, such as Cohesity and Rubrik, so that was not much of an option. The only thing we were aware of and investigating was VMware Site Recovery Manager (SRM), which is VMware's built-in system, SRM, and played around with it. In comparison to Zerto at that time, Site Recovery Manager is a nightmare. Zerto was definitely the easy button when we were last investigating solutions. Zerto was better in terms of ease of use, visibility, and costs. Frankly, these are all the metrics that we looked at, and Zerto worked better than SRM as well as it was easier and cheaper.

What other advice do I have?

Do a PoC. Test it along with other solutions that you are looking at and make a decision. Our decision was easy, and it was Zerto.

We are changing the infrastructure supporting our primary crown jewel application and will be utilizing Zerto more heavily in that. We are expanding the amount of application servers as well as adding some database servers that Zerto will be responsible for, and currently aren't. We are expanding using Zerto because we are expanding the assets for our application. That is happening currently. We have been working on that switchover for the last 12 months. We are getting close to actually deploying all those changes in production, so that is a fairly recent and ongoing task.

We haven't had to deal with a data recovery situation due to ransomware or other causes. We have a combination of luck and some pretty good security measures in place to where we haven't had an impactful ransomware event, CryptoLocker event, etc. In that event, I don't think Zerto would probably be the first thing that we would try to utilize. We have some pretty good backup mechanisms as well. We would probably look to those first to restore from backups. We have a fairly aggressive backup schedule with many servers backed up once an hour or more, which contain critical data. That is probably where we would go first.

There is a need to have both DR and backup in one solution, but it is not important. There are better backup methodologies that we use and they cover more use cases.

We are not utilizing any cloud resources for DR at this point. Our applications are very CPU and memory intensive, which becomes very expensive to run in the cloud.

We have other mechanisms for long-term retention.

Biggest lesson learnt: Disaster recovery doesn't have to be the biggest challenge in your organization.

I would rate Zerto as eight out of 10. The rating may not sound great, but it is pretty high for me.

Top 10
Easy to use with a straightforward interface and menus, and provides excellent analytics, reporting, and monitoring
Pros and Cons
  • "Zerto's ease of use is outstanding; it's easy to set up and has a clear interface and menus. The reporting, analytics, and online monitoring are also excellent."
  • "Improvements in stability would be welcome; there are some software bugs that can affect RPOs. We want more of a guarantee that we won't lose any of our backups, even in the event of a disaster."

What is our primary use case?

We use Zerto for backups and DR; we back up to a StoreOnce unit and then offsite. We have over 11 servers, including three Oracle servers, one Oracle database, and an Active Directory. 

How has it helped my organization?

Before Zerto, we used another solution that caused database crashes and did not offer certainty regarding disaster recovery. Zerto is more configurable and stable.

A DR site reduces downtime, especially with full VM backup and online synchronization. Zerto accomplishes this without affecting network efficiency, as synchronization occurs at specific intervals.

What is most valuable?

Zerto's ease of use is outstanding; it's easy to set up and has a clear interface and menus. The reporting, analytics, and online monitoring are also excellent.  

Compared to other solutions, the speed of recovery with Zerto is faster. Our last backup solution, Data Protector, was very slow, but Zerto is rapid even in file retrieval. 

The solution helped reduce our organization's DR testing; it's hard to say precisely how much, but Zerto does faster DR testing than other products.

What needs improvement?

Improvements in stability would be welcome; there are some software bugs that can affect RPOs. We want more of a guarantee that we won't lose any of our backups, even in the event of a disaster. 

The platform measures the right speed of storage devices and gives an alert on the VPG if there is latency, but the nature of the alert suggests the solution isn't meeting the SLA. However, this shouldn't affect the health status of the backup. It should provide an express report that we should enhance our hardware rather than express latency as a threat to the backup capability.

For how long have I used the solution?

We've been using the solution for two years. 

What do I think about the stability of the solution?

The stability is acceptable, we experienced an issue once, but the backup time is speedy.

What do I think about the scalability of the solution?

The solution's architecture supports business owners to expand their disaster recovery capabilities as their infrastructure grows. Additionally, Zerto's ability to integrate with various cloud platforms and on-premises environments further enhances its scalability, offering a flexible and robust solution for organizations with evolving needs.

How are customer service and support?

Customer support is one of Zerto's best aspects; the support is excellent, and we can quickly get through to them. I rate them ten out of ten. The support staff are very kind and always solve a problem. I feel secure knowing I have access to such good support.

How would you rate customer service and support?

Positive

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

We previously used Micro Focus Data Protector and Veeam Backup & Replication. Zerto is easier to use and more straightforward to configure. 

Zerto replaced our legacy backup solution, Data Protector. This not only saved on the cost of the old product but also provided more stability and security to our company. We now have a new backup methodology, and it's a significant upgrade.  

How was the initial setup?

I carried out the initial setup with support from Zerto, which was very straightforward.

The only requirement for maintenance is monitoring the solution and updating versions.

What about the implementation team?

I have 20 years of experience in IT, so I was well-positioned to carry out the deployment myself, with the assistance of Zerto support.

What was our ROI?

We have seen an ROI with Zerto. 

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

The pricing is slightly above average, but the immediate and comprehensive support makes the price acceptable.

Which other solutions did I evaluate?

We evaluated many other options but found Zerto the best, especially for our HPE environment. It's the most stable and straightforward tool, and even those with limited experience can operate it.

What other advice do I have?

I rate the solution eight out of ten. 

I strongly recommend Zerto; I've tried many other solutions, but it's the most stable.

We use the product to help protect VMs in our environment, and regarding RPOs, I carry out the test for them every six months, and it's working correctly.

I advise those evaluating the solution to use it, especially in an HPE environment, as it's fully compatible and easy to manage. There is no requirement for special drivers or configurations.

Has really good near-synchronous replication and protection, which is an advantage for customers
Pros and Cons
  • "We used Zerto to protect VMs in our environment. It depends on the network and environment, but the RTO takes around 7-8 seconds. When you compare Zerto to other solutions in the market, it's very powerful."
  • "You have to start with 25 VMs which is too much for SMB clients. It would be better if they had the option to start with 10."

What is our primary use case?

We use the solution for running demos for HPE partners and customers, regarding disaster recovery and backup.

How has it helped my organization?

Although our primary use case is to show demos to partners and customers, we think it's really valuable.

What is most valuable?

The most valuable features are disaster recovery and that the RTO takes less than ten seconds. It's a reallypotent tool.

The near-synchronous replication is really good and an advantage for customers. This feature is really important because we can show it to customers and partners, helping recovering from ransomware, and does provide huge value.

You can protect your VMs in the environment. It depends on the network and environment, but the RTO takes around 7-8 seconds. When you compare Zerto to other solutions in the market, it's very powerful. 

Also, the ease of use and speed of recovery are wonderful. 

What needs improvement?

I'm happy with the solution, but I would like Zerto to support other hypervisors too

And the price could be cheaper, but it is reasonable.

For how long have I used the solution?

I have been using Zerto for two years.

What do I think about the stability of the solution?

It's very stable. 

What do I think about the scalability of the solution?

The scalability is really good. 

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

We have used SRM from VMware and RapidDR from Simplivity. In comparison to those products, Zerto is really simple to use and helpful. 

We are constantly trying new products. Zerto has the lowest RTO, you can recover a lot more quickly than using other solutions. 

How was the initial setup?

The initial setup is very easy.

What about the implementation team?

We did the implementation ourselves. 

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

Our clients think it's quite expensive but I advise them to consider all of Zerto's features.

You need to start with 25 VMs, which sometimes is too much for SMB clients in some countries. It would be better if they had the option to start with a license for less VMs, like 5 or 10.

What other advice do I have?

Overall, I rate the solution a nine out of ten because of the low RTOs, the ease of use, and how helpful it is for clients.

Enables disaster recovery in the cloud and has good migration features
Pros and Cons
  • "I've found the migration feature very valuable."

    What is our primary use case?

    One of our biggest use cases has been migrations. We migrated the virtual machines in one of our data centers using Zerto.

    How has it helped my organization?

    We're in the middle of a migration that Zerto has made much easier. We also use it for many standard disaster recovery cases. It constantly keeps our services running.

    Zerto's near-synchronous replication is a key component. It's essential.

    Zerto enables disaster recovery in the cloud, which is very important. It creates another level of protection to have an alternate location outside of on-premises.

    It helps protect VMs in our environment. It's certainly better than a traditional nightly backup.

    What is most valuable?

    I've found the migration feature very valuable. It starts like a disaster recovery scenario where you're just replicating the VMs. Then it all gets synced up, and you decide when to make the cutover. 

    This is instead of having to do a more traditional conversion of the VMs or shutting them down and migrating the data, which is less efficient.

    The seamlessness of a cutover is very helpful.

    For how long have I used the solution?

    I have been using Zerto for around five years. 

    What do I think about the stability of the solution?

    It offers good stability. 

    What do I think about the scalability of the solution?

    We haven't scaled it too much, but in our experience, we haven't had any issues with it.

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

    We still use a different disaster recovery solution but for different use cases. 

    Zerto didn't completely replace our other backup solutions.

    What was our ROI?

    There are cost savings for the migration in particular.

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

    From the migration standpoint, they're flexible with the licensing. You own the license and can apply it to a machine and then pull it back, apply it to another machine, and so on.

    Which other solutions did I evaluate?

    For the migration piece, we evaluated different solutions but not for the disaster recovery replication. We knew from the migration piece that it would work well.

    What other advice do I have?

    For me, it's a ten. I haven't had any issues with it so far.

    Easy to use with great speed of recovery and helpful support
    Pros and Cons
    • "It's the easiest to use."
    • "The technical support is hit or miss."

    What is our primary use case?

    We are primarily using it for migration and data protection. We use it for protection of the VM and data protection. 

    How has it helped my organization?

    It's the easiest way to support DR as it does the conversion for you. After converting, it protects again. If you don't want Azure, you can just go back on-premises, for example. 

    We can monitor VMs more easily with Zerto. We can always check if they aren't properly syncing. The migrations are also easy. 

    What is most valuable?

    The overall impact on our RPOs has been amazing. The ease of using it is great. Everyone is embracing it in our company.

    The ease of use is ten out of ten. It's the easiest to use. 

    The speed of recovery is great, especially the failover/failback. It helps our company a lot. 

    The most valuable feature is the GUI. It's very simple. 

    Setting it up is very easy. 

    Everything is automated using scripts. 

    The solution saves a lot of time and there is no downtime based on how the product is designed. If there's any downtime, it's only a second or two if we move. 

    The near-synchronous replication is great. It just works. I'm a big fan of Zerto.

    What needs improvement?

    Right now, the solution is perfect. They shouldn't try to do everything. Zerto is DR and needs to focus on that. Everything works for us. There is nothing to improve. 

    They already released the features that we want. We aren't missing any features. 

    For how long have I used the solution?

    I've been using it for almost five years now. 

    What do I think about the stability of the solution?

    At first, when Zerto was bought by HP, we thought it was just going to be HP. However, Zerto is really working out and the stability is great. I hope they continue what they are doing and refrain from making major changes. 

    What do I think about the scalability of the solution?

    Zerto scales pretty well. They have a lot of customers. The word of mouth is helping with growth.

    It scales well with our environment with the conversion from VM to Azure and vice versa. It's so easy. There's no middle-man involved. It's just Zerto. 

    How are customer service and support?

    The technical support is hit or miss. If it is a high-priority ticket, you get great Zerto support, however, if you just have a question, they redirect you to their documents. 

    How would you rate customer service and support?

    Positive

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

    We previously used SRM before Zerto. 

    How was the initial setup?

    The initial setup was not hard at all. We deployed a VM and had our team open the ports and we were all set. 

    It only takes about an hour or two if you have the proper people helping you with the networking. 

    What was our ROI?

    We have witnessed a lot of ROI. Being technical, I always ask to make sure management is happy with the product we are trying to use. With the migration feature, it's way better now. We are able to migrate from the old data center without any disruption. That's a big win. 

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

    The pricing is fair. The pricing is very competitive and it works well. You are paying for a product that is easy to use and just works. 

    Which other solutions did I evaluate?

    We've evaluated multiple DRs and some VMware products. Zerto was the winner due to the GUI. Also, it just works.

    What other advice do I have?

    I have colleagues who are doing a POC with Zerto and will begin using it based on my recommendation. 

    I'd rate the solution ten out of ten. If I could give it eleven out of ten I would. 

    Which deployment model are you using for this solution?

    Hybrid Cloud

    If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

    Is fast to set up and has valuable replication features
    Pros and Cons
    • "It reduced the time for DR tests from the infrastructure side. Being able to get our work done in a matter of a couple of minutes so the app teams can get to work and can do their testing has been significant."
    • "We would love to have a native management pack for vROps and to be able to view a dashboard and metrics for BPGs within vROps. We would like to have a single view for monitoring and provide customers with dashboards so they can see their own BPGs."

    What is our primary use case?

    We use Zerto as a DR tool. Instead of having to have a duplicate DR server, we can add a system to BPG and point it to whatever our DR site will be and replicate it for customers.

    We also use it for migration planning. If we need to move VMs from on-premise to Azure or back, or it was built in the wrong place, we can easily move it over. 

    How has it helped my organization?

    It reduced the time for DR tests from the infrastructure side. Being able to get our work done in a matter of a couple of minutes so the app teams can get to work and can do their testing has been significant. 

    Before we would have to use a backup recovery tool to restore it to a LAN, which could take hours at times, depending on the solution that was being used. 

    What is most valuable?

    The replication features are most valuable. It's fast to set up a BPG and get a system added. This aspect is very important to our business. Being able to provide customers with a very fast DR experience, whether it's for a test or live case scenario, and being able to provide the ability to move systems to Azure for cost savings or migrations, saves our ops teams a lot of time.

    What needs improvement?

    We would love to have a native management pack for vROps and to be able to view a dashboard and metrics for BPGs within vROps. We would like to have a single view for monitoring and provide customers with dashboards so they can see their own BPGs. 

    We would also like to have a native plugin for VRA built by either VMware or Zerto. That way there's actual support for it and we're not on the hook for trying to figure out what happened if it breaks.

    For how long have I used the solution?

    We have been using Zerto for four years.

    What do I think about the stability of the solution?

    The only problems we've had stability-wise come from upgrades.

    What do I think about the scalability of the solution?

    This is a scalable solution. The only challenge is that there's no way to manage it centrally at the moment. If you have 30 vCenters, you now have 30 appliances and you have to remember where everything is, which can become a pain point when it comes to trying to find where this VM is being replicated and what BPG it's in. 

    How are customer service and support?

    The support for this solution could be improved. It is challenging for staff who actually understand the product. We had issues where we ended up spending hours and sometimes days on the phone, only for us to figure it out on our own.

    They're very personable and fine to work with. It seems like technical expertise is lacking. I would rate them a five out of ten.

    How would you rate customer service and support?

    Neutral

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

    I haven't used too many other disaster recovery tools. We used standard backup solutions and Zerto is significantly faster. 

    What other advice do I have?

    I would rate this solution a nine out of ten.

    Has the ability to IP customize during failovers and has a faster recovery speed
    Pros and Cons
    • "I like the less than one-minute RPO, the ability to IP customize during failovers, and the cloning feature that I can use to clone VMs over at the target location. As part of the automation failover, if we need to change an IP when it fails over to the other data center, Zerto will handle that; there's no need for manual intervention. As far as the cloning, we use that to do quick testing of a VM in the remote data center for lift-and-shift processors."
    • "One issue we've been having with Zerto lately is the ability to go into maintenance mode during vSphere upgrades. It doesn't have the hook into the lifecycle manager of the bump. During vCenter or ESXi upgrades, it causes VCF to fail its pre-checks because the machine doesn't power off and go into maintenance mode. It's been an issue since version 7.5 and it's impacting a basic automation function in vSphere."

    What is our primary use case?

    We primarily use it for disaster recovery.

    What is most valuable?

    I like the less than one-minute RPO, the ability to IP customize during failovers, and the cloning feature that I can use to clone VMs over at the target location. As part of the automation failover, if we need to change an IP when it fails over to the other data center, Zerto will handle that; there's no need for manual intervention. As far as the cloning, we use that to do quick testing of a VM in the remote data center for lift-and-shift processors.

    In terms of ease of use, Zerto is better than SRM now because you can do automated VM protection. As long as you set it up, enable it, put the tags on the VMs, and have the template VPG created, it works. With SRM, we use array-based replication, so anytime a VM goes on a replicated data store and that replicated data store is in a protection group in SRM, it's automatically protected. So there's no intervention needed to protect that VM. Initially, the fact that I had to manually create the VPGs when a new VM came in was a con for me with Zerto when I was comparing it to SRM, but now, I'm happy with Zerto's automated VM protection. We currently use both Zerto and SRM in tandem.

    If I had to manually create the VPGs, it could take thousands of minutes.

    As far as the speed of recovery, Zerto is faster than SRM because, with SRM, we use array-based replication. This means that we have to shut down the machine, detach the data store, and attach it to the other side. All of this takes time. In Zerto, that doesn't happen because it's continuous, VM-level replication. So, the data is going right over to the other target data store. When we run the recovery on Zerto, we recover a VM in under 10 minutes, so the RTO is less than 10 minutes, as opposed to some SRM plans that can run an hour or two hours.

    What needs improvement?

    One issue we've been having with Zerto lately is the ability to go into maintenance mode during vSphere upgrades. It doesn't have the hook into the lifecycle manager of the bump. During vCenter or ESXi upgrades, it causes VCF to fail its pre-checks because the machine doesn't power off and go into maintenance mode. It's been an issue since version 7.5 and it's impacting a basic automation function in vSphere.

    For how long have I used the solution?

    I've been using Zerto since 2018.

    What do I think about the stability of the solution?

    Zerto is pretty solid in terms of stability.

    What do I think about the scalability of the solution?

    I'm sure it scales well. In our legacy environment, we only used a 100-pack license, so we only used 60 machines on that license. That was a fairly small footprint. In this new environment, we estimate at least a couple of thousand because we're shifting from SRM to Zerto. I expect it to scale well.

    How are customer service and support?

    Zerto's technical support is better than that of most vendors that I deal with. I can open up a support ticket and have someone get back to me within a couple of hours. Even with a Severity 3 ticket, someone will email me within a couple of hours. I will rate them a nine out of ten.

    How would you rate customer service and support?

    Positive

    How was the initial setup?

    The initial setup process is simple. You get the executable, you stand up a VM, you install it on a VM and open up firewalls, and connect the ZVM to the ZVRA data sites. It's fairly straightforward.

    You can deploy Zerto in under two hours, as long as the firewall is in place. When the firewall is in place, everything runs smoothly. Otherwise, it takes a while.

    What about the implementation team?

    I deployed it myself.

    What was our ROI?

    I do think that we've seen a return on investment. We started off with SRM in our legacy environment, and it was probably protecting 90% of the estate. Now, we have a new environment, and Zerto is now protecting 90% of the estate, and SRM is only doing 10% or even less than that.

    What other advice do I have?

    It's a nice tool, and you should go for it. I don't think you'll be disappointed. On a scale from one to ten, I would rate Zerto at ten.

    Does not rely on a secondary backend product and is easier and more straightforward to use
    Pros and Cons
    • "I found VM level replication and being able to group the VM levels to be valuable. I like not having to worry about whether a particular VM is in the right storage group; some of those sorts of things would trip us up previously."
    • "There's one feature that SRM had that Zerto doesn't have, and it's one that we've been asking for. With the orchestration part of the failover, with our DR and our primary sites, the IP addresses are almost identical. The only difference is one octet. With SRM, we could say during a failover change. With Zerto, we keep hearing that it's coming, but we haven't received it yet. It's a feature that would be very beneficial. It would reduce the time a little bit more."

    What is our primary use case?

    We primarily use it for DR, that is, for VM replication between two data centers, using it not only for replication but also for orchestration.

    How has it helped my organization?

    Zerto provided better overall DR coverage and more consistency.

    What is most valuable?

    I found VM level replication and being able to group the VM levels to be valuable. I like not having to worry about whether a particular VM is in the right storage group; some of those sorts of things would trip us up previously. 

    It's a lot easier and more straightforward for a VM administrator because he can know that this VM goes in this group or gets this tag, for example, and that it's now in a DR group and is taken care of. I don't have to worry about all the backend details. It's just simplified.

    In terms of ease of use, the benefit of Zerto over SRM is the fact that it doesn't rely on a secondary backend product, with having to have the right storage groups with RecoverPoint or something else with multi-tier architecture.

    It's still too early to compare the speed of recovery with Zerto versus the speed of recovery with other disaster recovery solutions. We've just started the DR tests to understand the time difference. However, from what I've seen so far, the speed of recovery is similar but more consistent with Zerto. We don't have situations where we've missed this or that.

    Zerto reduced the staff involved in data recovery situations by a single person. Now, we don't have the backend storage person who has to keep an eye on it anymore. With a different solution, we would have needed two people.

    What needs improvement?

    There's one feature that SRM had that Zerto doesn't have, and it's one that we've been asking for. With the orchestration part of the failover, with our DR and our primary sites, the IP addresses are almost identical. The only difference is one octet. With SRM, we could say during a failover change. With Zerto, we keep hearing that it's coming, but we haven't received it yet. It's a feature that would be very beneficial. It would reduce the time a little bit more.

    For how long have I used the solution?

    I've been working with Zerto for about two years.

    What do I think about the stability of the solution?

    The stability seems fine. I haven't seen any issues with it thus far.

    What do I think about the scalability of the solution?

    For our organization, the scalability matched our needs. Between the data centers, we probably have somewhere in the neighborhood of 3,000 VMs.

    How are customer service and support?

    From what I have seen, the technical support has been very good. They've been very responsive to my team.

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

    We previously used SRM. Zerto is a little bit more mature, has a better feature set, and is more aligned with the features and functionalities that we need.

    What was our ROI?

    We have seen an ROI from the perspective of a reduction in hardware and a reduction in the number of people trying to focus on the tool sets.

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

    It is less expensive than the full solution that we had previously, but at the same time, it's not an inexpensive product either.

    Which other solutions did I evaluate?

    We evaluated Cohesity and other solutions.

    What other advice do I have?

    Overall, Zerto is a very good product for us, and I would rate it at nine on a scale from one to ten.
