Provides continuous data protection and decreases the time and the number of people involved
Pros and Cons
  • "It works very well in terms of it providing continuous data protection. It does what it says it is going to do. We have been using it for several years, and once or twice, we had to recover a machine or files. It didn't have any problems in doing what it is supposed to be doing."
  • "It just gives us extra peace of mind; we can backup and recover critical information not only on-premise but also off-premise at multiple places, and it has saved us somewhere in the $150,000 to $200,000 range."
  • "We would like some of the real fine or granular things. We've submitted a few minor things for enhancements such as being able to control bandwidth utilization for each facility you replicate to versus overall. We just need a little bit more granularity on some of the things, but there is not a whole bunch that is in need of tweaking."

What is our primary use case?

It is for real-time data protection and, if needed, for the ability to recover within seconds at a point in time. It is deployed on-premise and multi-cloud on Azure and AWS.

How has it helped my organization?

It just gives us extra peace of mind. We can backup and recover critical information not only on-premise but also off-premise at multiple places. So, we have that additional place for recovery if Azure or AWS is having problems.

When we need to fail back or move workloads, Zerto decreases the time and the number of people involved. It definitely speeds up the process of recovery for us. We essentially need only one person for the recovery process. In other solutions that we had in the past, we had to involve quite a few of our team members in the recovery process. We haven't had to do fail back a lot, so I can't give a real numeric number of how much it has saved us. If we had to do a big fail back, I can see where it could have saved us.

It has reduced the number of staff involved in a data recovery situation. The number of staff involved is less than what it used to be. We can basically do that with one person. It also reduces the number of staff involved in overall backup and DR management.

It has saved us money by enabling us to do DR in the cloud rather than in a physical data center. We don't have to buy another SAN, so it has saved somewhere in the $150,000 to $200,000 range.

What is most valuable?

The reliability of the solution and ease of upgrades are most valuable. Support has also been really good on it.

It works very well in terms of it providing continuous data protection. It does what it says it is going to do. We have been using it for several years, and once or twice, we had to recover a machine or files. It didn't have any problems in doing what it is supposed to be doing.

It is easy to use once you have gone through the online training class to learn the basics about it. We have been able to get a couple of our folks in the IT department up to speed on how it works and how to utilize it within basically a day or less. It is relatively easy for us to get staff trained and get going.

What needs improvement?

We would like some of the real fine or granular things. We've submitted a few minor things for enhancements such as being able to control bandwidth utilization for each facility you replicate to versus overall. We just need a little bit more granularity on some of the things, but there is not a whole bunch that is in need of tweaking.

Learn what your peers think about HPE Zerto Software. Get advice and tips from experienced pros sharing their opinions. Updated: August 2026.
908,858 professionals have used our research since 2012.

For how long have I used the solution?

We've been using this solution for three years.

What do I think about the stability of the solution?

It has been very stable for us. We haven't had any issues with it. Even upgrades have been relatively seamless for us. If anything, it is just that you miss something on the upgrade release note and you need to open a port or something else, but there is nothing critical.

What do I think about the scalability of the solution?

It seems to be very scalable. We're not that big, but it seems to scale out for us and give us more scale for what we are size-wise. It could be very beneficial for a bigger organization.

We started out protecting roughly 30 terabytes of data, and that's roughly where we're right now. We have 30 terabytes of data and 250 employees. We are just trying to keep them all functioning 24/7.

At the moment, we don't have any plans to increase the usage. We're utilizing everything we can at the moment. The only thing that we might consider down the road is the backup functionality long-term, but that's something we just keep evaluating versus what we currently have. What we currently have works so well, and we don't really want to change it.

How are customer service and support?

Their support has been really good. They've been very proactive in helping resolve issues, and you get quick callbacks or contact with them. I would rate them a 10 out of 10.

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

They used Avamar Data Domain before Zerto. It had a very complicated process, and the price was also very high. It did not have a similar granularity of recovery points.

How was the initial setup?

It was pretty straightforward. We had it fully installed and started implementing it within the first couple of hours of the process. We worked with the local rep for about an hour or two, and by then, we had the process down. After that, it was pretty straightforward, and we just replicated that for additional protection groups.

In terms of the implementation strategy, we knew what we needed. We wanted to get out in the cloud. We focused on Azure to start with and then came back and looked at AWS after the fact for a couple of use cases where Azure wasn't the best place for some big data sets.

For its day-to-day maintenance or administration, there is just me. We do have desktop admins that can get into it as well if they need to be, but generally, I take care of it all for them. They just holler out if they have a problem or a question about something, and I can take care of it for them.

What about the implementation team?

We worked with the local rep for about an hour or two. Our experience with him was very good. He was very helpful and knowledgeable about the product and also about the ways other folks were using the product.

What was our ROI?

There is nothing that we can quantitatively define, but we are able to meet regulatory requirements.

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

It initially seemed a little pricey, but in the big picture, you're paying for peace of mind. It could always be cheaper and more competitive, which would make it an easier choice for people, but I can see both ways. They can say this cost is for the value they are providing. If anything happens, they can recover your data very quickly. You won't be losing it, so there is a win. It is a win-win.

Which other solutions did I evaluate?

We evaluated VMware Site Recovery Manager. I have used that in the past, and it is okay, but upgrades tend to break a lot of stuff, whereas Zerto hasn't had that kind of issue, which is great. It is never a good thing to do a minor update and then your whole system is dead for maybe a day or two until you figure out what caused the breakage. We also looked at SRM and Cohesity. Cohesity was more for just overall backup, not for full DR.

Zerto was very easy to use. We could use it for backup and DR, which was very important for us. That was one of the key driving factors for us.

What other advice do I have?

I would advise others to just get the training before utilizing it so that you have a better understanding of the overall product. You should also have plenty of bandwidth for your providers so that replication works seamlessly.

It has helped us a little bit in reducing downtime in a couple of cases. It saved us a few hours here and there. It could save us time in a data recovery situation due to ransomware or other causes. We haven't had to use it currently for that. Its overall backup and DR management could also reduce the number of people needed.

We don't use Zerto for long-term retention. We have another solution in place for that. We will evaluate Zerto possibly down the road.

I would rate Zerto a 10 out of 10.

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."
  • "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."
  • "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.

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 technical 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.

Which deployment model are you using for this solution?

Simple to set up and use, and offers continuous data protection with a five-second interval
Pros and Cons
  • "This product is impressively easy to use. It's dummy-proof, once it's set up."
  • "My advice to anybody who is considering Zerto is that it's an awesome product and it won't steer them wrong."
  • "The long-term recovery is a little bit weak in its granularity."
  • "Rating the Zerto technical support is a little bit tough because I've had some experiences that were truly 10 of 10, but then I've had one or two experiences where it was definitely a two or a three out of 10."

What is our primary use case?

We use Zerto for real-time replication of our systems, company-wide. The main reason is disaster recovery failover.

How has it helped my organization?

We use the long-term retention functionality, although it is not deployed system-wide. We have a lot of critical systems backed up, such as our file servers. We utilize it to hold things for up to a year and we send our long-term retention to ExaGrid appliances.

When we need to failback or move workloads, this solution has decreased the time it takes and the number of people involved. The entire process is, realistically, a one-person job. We usually have an application specialist involved just to validate the health of the server. Whether it's an SQL server or application server, we have somebody that runs integrity checks on it. That said, the entire process is very painless and easily handled by one person.

I estimate that this product saves us hours in comparison to products like Veeam. Veeam would take several hours of time to fail something over. 

Our company fell victim to a ransomware attack that affected between 50 and 60 servers. Until we knew for sure that the entire situation was remediated and that we weren't going to spread the infection, we restored the servers in an offline manner, which only took a matter of minutes to complete. Then, we pushed all of that data into Teams and OneDrive directly for people to start accessing it.

From the SQL server perspective, we failed those servers over, running health checks such as anti-virus scans, just to make sure that the failed over instance didn't contain the same situations. Thankfully, they did not. We probably saved ourselves several days worth of work in the grand scheme of things. In total, it potentially would have taken weeks to resolve using a different solution.

I wouldn't necessarily say that using Zerto has meant that we can reduce the number of staff in a recovery operation. However, I think it's probably mitigated the need to hire more people. Essentially, as we've continued to grow, we've avoided adding headcount to our team. Using Veeam as my problem child to compare against, if we were using it, it would have required a lot more management from us. It would have cost us more time to recover and manage those jobs, including the management of the ExaGrid appliances, as well as the VRAs, which are basically proxies.

Definitely, there is a huge saving in time using Zerto and although we didn't reduce any headcount or repurpose anything, we've definitely mitigated at least two people from the hiring perspective.

Zerto saved us considerable downtime when we experienced the ransomware attack. It may be hard to substantiate that just on the one situation but we saved at least a couple of million dollars.

What is most valuable?

The most valuable feature is the continuous recovery with the five-second checkpoint interval. Just having those checkpoints prior to when a situation arises, we're able to get the transactional data that occurred right before the server failed. That has been a blessing for us, as we are able to provide a snapshot with no more than five seconds of data loss. This means that we don't have to recreate minutes or hours worth of data for an industry that includes fulfillment, shipping, warehousing, et cetera.

Zerto is very good at providing continuous data protection. It does a very good job keeping up with the system and it creates five-second interval checkpoints. This has been helpful when it comes to needing to fail something over, getting that last moment in time that was in a usable state.

This product is impressively easy to use. It's dummy-proof, once it's set up.

What needs improvement?

The long-term recovery is a little bit weak in its granularity. Veeam is definitely superior in that aspect, as it's able to provide a granular view of files and databases, et cetera. However, it just kind of depends on what a business' recovery strategy is.

From our business perspective, it's really not impactful to us because our recovery strategy is not based on individual files. But, I could definitely see it being a challenge if there is a very large instance of individual files, as a subset, that need to be recovered. I think that if somebody has terabytes of data then Zerto will recover it faster but navigating through the file explorer to get to files is not as easy with Zerto.

One thing I don't like about the product, and I know this is where their claim to fame is, but whenever I have a VPG that has multiple virtual machines in it, and one virtual machine falls behind, it'll pause replication on everything else in that job until the one server catches up. The goal is to keep symmetric replication processing going, so the strategy makes sense, but for our business model, that doesn't really work and it has created a challenge where I have to manage each VM individually. It means that instead of having one job that would cover multiple servers, I just have one job to one server, which allows me to manage them individually.

For how long have I used the solution?

We have been using Zerto for approximately five years.

What do I think about the stability of the solution?

From a company perspective, a few years ago, I would have said that it is very stable. It is a solution that is thriving and growing. At this time, however, HP is in the process of acquiring them. While I had assumed that was their long-term plan, I didn't quite anticipate HP being the one to pick them up. As such, I am a little bit worried about what will change in the long term.

What do I think about the scalability of the solution?

Scalability-wise, it's a very painless product. As we continue to grow out our virtual environment, Zerto is able to, in a very nimble fashion, scale with us with very little effort or overhead involved.

I'm covering approximately 400 VMs currently, which is approximately 360 terabytes worth of data. That is between two separate data centers.

How are customer service and technical support?

Rating the Zerto technical support is a little bit tough because I've had some experiences that were truly 10 of 10, but then I've had one or two experiences where it was definitely a two or a three out of 10. It really depends on who I've gotten on the phone and their level of, A, comfort with their own system, and B, comfort helping the customer.

Some people have said this isn't within their scope of work, where others have said, "No, let's absolutely do this." In that regard, it's been a little hit and miss, but it's usually been a decent quality in the end.

Overall, I would rate the technical support a seven out of ten.

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

I have worked with Veeam in the past and although I prefer Zerto, there are some advantages to using Veeam. For example, long-term recovery offers more features.

In-house, we had also used the Unitrends product, as well as a SAN-to-SAN replication using an old HPE LeftHand array.

The main reasons that we switched to Zerto were the management ability, as well as its ability to provide continuous replication. Veeam was a very cumbersome product to manage. There were a lot of instances to monitor and manage from a proxy perspective, whereas Zerto's VRAs are relatively transparent in their configuration and deployment. These are painless and I don't have to continually monitor them. I don't have to update them since they're not like standalone Windows instances. It's very low management for us.

Of course, continuous replication is critical because Veeam, even though when we had owned the product, it claimed 15-minute intervals were doable, it never seemed to actually keep up with those 15-minute snapshot intervals.

One final reason that we migrated from Veeam is that they were utilizing VM snapshots at the time. I know that they've moved away from that approach now, but it was very painful for our environment at the time. The VMware snapshots were causing some of our legacy and proprietary applications to fail.

How was the initial setup?

The initial setup is very simple.

Our implementation strategy involved setting it up for our two data centers. We have a primary and secondary data center, and Zerto keeps track of all of the VMs at the primary site and replicates them to the other site.

In the future, we plan on looking into the on-premises to cloud replication. On-premises to Azure direct is on our roadmap.

What about the implementation team?

I completed the setup myself without support or anybody else involved in the deployment.

It took approximately an hour to deploy.

I handle all of the administration and maintenance. As the senior manager of infrastructure, I oversee our work and server group. I have also retained private ownership over the disaster recovery plan and failover plan.

What was our ROI?

We have probably not seen a return on investment from using Zerto. We don't really have lots of situations where we have to use it and can substantiate any kind of financial claim to it.

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

I do not like the current pricing model because the product has been divided into different components and they are charging for them individually. I understand why they did it, but don't like the model. 

Our situation is somewhat peculiar because when we bought into it, we owned everything. Later on down the road, they split the licensing model, so you had to pay extra for the LTR and extra for the multi-site replication. However, since we were using LTR prior to that license model change, they have allowed us to retain the LTR functionality at our existing licensing level, but not have the multi-site replication.

Which other solutions did I evaluate?

We have not evaluated other options in quite a long time. We very briefly evaluated Rubrik. 

What other advice do I have?

When we first decided to implement Zerto, it wasn't very important that it provides both backup and DR in one platform. In fact, realistically, even now, while we have it and we used it on a limited scope, I'm not sure that it's needed.

With respect to our legacy solutions, I'd say that the cost of replacing them with Zerto is net neutral in the end.

My advice to anybody who is considering Zerto is that it's an awesome product and it won't steer them wrong. That said, there are some issues such as the licensing model and the situations where VPGs falling behind suspends the replication. Overall, it is a good product.

I would rate this solution an eight out of ten.

Easy-to-use interface, good telemetry data, and the support is good
Pros and Cons
  • "If we lost our data center and had to recover it, Zerto would save us a great deal of time. In our testing, we have found that recovering the entire data center would be completed within a day."
  • "The onset of configuring an environment in the cloud is difficult and could be easier to do."

What is our primary use case?

Originally, I was looking for a solution that allowed us to replicate our critical workloads to a cloud target and then pay a monthly fee to have it stored there. Then, if some kind of disaster happened, we would have the ability to instantiate or spin up those workloads in a cloud environment and provide access to our applications. That was the ask of the platform.

We are a manufacturing company, so our environment wouldn't be drastically affected by a webpage outage. However, depending on the applications that are affected, being a $15 billion dollar company, there could be a significant impact.

How has it helped my organization?

Zerto is very good in terms of providing continuous data protection. Now bear in mind the ability to do this in the cloud is newer to them than what they've always done traditionally on-premises. Along the way, there are some challenges when working with a cloud provider and having the connectivity methodology to replicate the VMs from on-premises to Azure, through the Zerto interface, and make sure that there's a healthy copy of Zerto in the cloud. For that mechanism, we spent several months working with Zerto, getting it dialed in to support what we needed to do. Otherwise, all of the other stuff that they've been known to do has worked flawlessly.

The interface is easy to use, although configuring the environment, and the infrastructure around it, wasn't so clear. The interface and its dashboard are very good and very nice to use. The interface is very telling in that it provides a lot of the telemetry that you need to validate that your backup is healthy, that it's current, and that it's recoverable.

A good example of how Zerto has improved the way our organization functions is that it has allowed us to decommission repurposed hardware that we were using to do the same type of DR activity. In the past, we would take old hardware and repurpose it as DR hardware, but along with that you have to have the administration expertise, and you have to worry about third-party support on that old hardware. It inevitably ends up breaking down or having problems, and by taking that out of the equation, with all of the DR going to the cloud, all that responsibility is now that of the cloud provider. It frees up our staff who had to babysit the old hardware. I think that, in and of itself, is enough reason to use Zerto.

We've determined that the ability to spin up workloads in Azure is the fastest that we've ever seen because it sits as a pre-converted VM. The speed to convert it and the speed to bring it back on-premises is compelling. It's faster than the other ways that we've tried or used in the past. On top of that, they employ their own compression and deduplication in terms of replicating to a target. As such, the whole capability is much more efficient than doing it the way we were doing it with Rubrik.

If we lost our data center and had to recover it, Zerto would save us a great deal of time. In our testing, we have found that recovering the entire data center would be completed within a day. In the past, it was going to take us close to a month. 

Using Zerto does not mean that we can reduce the number of people involved in a failover.  You still need to have expertise with VMware, Zerto, and Azure. It may not need to be as in-depth, and it's not as complicated as some other platforms might be. The person may not have to be such an expert because the platform is intuitive enough that somebody of that level can administer it. Ultimately, you still need a human body to do it.

What is most valuable?

The most valuable feature is the speed at which it can instantiate VMs. When I was doing the same thing with Rubrik, if I had 30 VMs on Azure and I wanted to bring them up live, it would take perhaps 24 hours. Having 1,000 VMs to do, it would be very time-consuming. With Zerto, I can bring up almost 1,000 VMs in an hour. This is what I really liked about Zerto, although it can do a lot of other things, as well.

The deduplication capabilities are good.

What needs improvement?

The onset of configuring an environment in the cloud is difficult and could be easier to do. When it's on-premises, it's a little bit easier because it's more of a controlled environment. It's a Windows operating system on a server and no matter what server you have, it's the same.

However, when you are putting it on AWS, that's a different procedure than installing it on Azure, which is a different procedure than installing it on GCP, if they even support it. I'm not sure that they do. In any event, they could do a better job in how to build that out, in terms of getting the product configured in a cloud environment.

There are some other things they can employ, in terms of the setup of the environment, that would make things a little less challenging. For example, you may need to have an Azure expert on the phone because you require some middleware expertise. This is something that Zerto knew about but maybe could have done a better job of implementing it in their product.

Their long-term retention product has room for improvement, although that is something that they are currently working on.

For how long have I used the solution?

We have been with Zerto for approximately 10 years. We were probably one of the first adopters on the platform.

What do I think about the stability of the solution?

With respect to stability, on-premises, it's been so many years of having it there that it's baked in. It is stable, for sure. The cloud-based deployment is getting there. It's strong enough in terms of the uptime or resilience that we feel confident about getting behind a solution like this.

It is important to consider that any issues with instability could be related to other dependencies, like Azure or network connectivity or our on-premises environment. When you have a hybrid environment between on-premises and the cloud, it's never going to be as stable as a purely on-premises or purely cloud-based deployment. There are always going to be complications.

What do I think about the scalability of the solution?

This is a scalable product. We tested scalability starting with 10 VMs and went right up to 100, and there was no difference. We are an SMB, on the larger side, so I wouldn't know what would happen if you tried to run it with 50,000 VMs. However, in an SMB-sized environment, it can definitely handle or scale to what we do, without any problems.

This is a global solution for us and there's a potential that usage will increase. Right now, it is protecting all of our criticals but not everything. What I mean is that some VMs in a DR scenario would not need to be spun up right away. Some could be done a month later and those particular ones would just fall into our normal recovery process from our backup. 

The backup side is what we're waiting on, or relying on, in terms of the next ask from Zerto. Barring that, we could literally use any other backup solution along with Zerto. I'm perfectly fine doing that but I think it would be nice to use Zerto's backup solution in conjunction with their DR, just because of the integration between the two.  

How are customer service and technical support?

In general, the support is pretty good. They were just acquired by HP, and I'm not sure if that's going to make things better or worse. I've had experiences on both sides, but I think overall their support's been very good.

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

Zerto has not yet replaced any of our legacy backup products but it has replaced our DR solution. Prior to Zerto, we were using Rubrik as our DR solution. We switched to Zerto and it was a much better solution to accommodate what we wanted to do. The reason we switched had to do with support for VMware.

When we were using Rubrik, one of the problems we had was that if I instantiated the VM on Azure, it's running as an Azure VM, not as a VMware VM. This meant that if I needed to bring it back on-premises from Azure, I needed to convert it back to a VMware VM. It was running as a Hyper-V VM in Azure, but I needed an ESX version or a VMware version. At the time, Rubrik did not have a method to convert it back, so this left us stuck.

There are not a lot of other DR solutions like this on the market. There is Site Recovery Manager from VMware, and there is Zerto. After so many years of using it, I find that it is a very mature platform and I consider it easy to use. 

How was the initial setup?

The initial setup is complex. It may be partly due to our understanding of Azure, which I would not put at an expert level. I would rate our skill at Azure between a neophyte and the mid-range in terms of understanding the connectivity points with it. In addition to that, we had to deal with a cloud service provider.

Essentially, we had to change things around, and I would not say that it was easy. It was difficult and definitely needed a third party to help get the product stood up.

Our deployment was completed within a couple of months of ending the PoC. Our PoC lasted between 30 and 60 days, over which time we were able to validate it. It took another 60 days to get it up and running after we got the green light to purchase it.

We're a multisite location, so the implementation strategy started with getting it baked at our corporate location and validating it. Then, build out an Azure footprint globally and then extend the product into those environments. 

What about the implementation team?

We used a company called Insight to assist us with implementation. We had a previous history with one of their engineers, from previous work that we had done. We felt that he would be a good person to walk us through the implementation of Zerto. That, coupled with the fact that Zerto engineers were working with us as well. We had a mix of people supporting the project.

We have an infrastructure architect who's heading the project. He validates the environment, builds it out with the business partners and the vendor, helps figure out how it should be operationalized, configure it, and then it gets passed to our data protection group who has admins that will basically administrate the platform and it maintains itself.

Once the deployment is complete, maintaining the solution is a half-person effort. There are admins who have a background in data protection, backup products, as well as virtualization and understanding of VMware. A typical infrastructure administrator is capable of administering the platform.

What was our ROI?

Zerto has very much saved us money by enabling us to do DR in the cloud, rather than in our physical data center. To do what we want to do and have that same type of hardware, to be able to stand up on it and have that hardware at the ready with support and maintenance, would be huge compared to what I'm doing.

By the way, we are doing what is considered a poor man's DR. I'm not saying that I'm poor, but that's the term I place on it because most people have a replica of their hardware in another environment. One needs to pay for those hardware costs, even though it's not doing anything other than sitting there, just in case. Using Zerto, I don't have to pay for that hardware in the cloud.

All I pay for is storage, and that's much less than what the hardware cost would be. To run that environment with everything on there, just sitting, would cost a factor of ten to one.

I would use this ratio with that because the storage that it replicates to is not the fastest. There's no VMs, there's no compute or memory associated with replicating this, so all I'm paying for is the storage.

So in one case, I'm paying only for storage, and in the other case, I have to pay for storage and for hardware, compute, and connectivity. If you add all that up into what storage would be, I think it would be that storage is inexpensive, but compute added up with maintenance and everything, and networking connectivity between there and the soft costs and man-hours to support that environment, just to have it ready, I would say ten to one is probably a fair assessment.

When it comes to DR, there is no real return on investment. The return comes in the form of risk mitigation. If the question is whether I think that I spent the least amount of money to provide a resilient environment then I would answer yes. Without question.

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

If you are an IT person and you think that DR is too expensive then the cloud option from Zerto is good because anyone can afford to use it, as far as getting one or two of their criticals protected. The real value of the product is that if you didn't have any DR strategy, because you thought you couldn't afford it, you can at least have some form of DR, including your most critical apps up and running to support the business.

A lot of IT people roll the dice and they take chances that that day will never come. This way, they can save money. My advice is to look at the competition out there, such as VMware Site Recovery, and like anything else, try to leverage the best price you can.

There are no costs in addition to the standard licensing fees for the product itself. However, for the environment that it resides in, there certainly are. With Azure, for example, there are several additional costs including connectivity, storage, and the VPN. These ancillary costs are not trivial and you definitely have to spend some time understanding what they are and try to control them.

Which other solutions did I evaluate?

I looked at several solutions during the evaluation period. When Zerto came to the table, it was very good at doing backup. The other products could arguably instantiate and do the DR but they couldn't do everything that Zerto has been doing. Specifically, Zerto was handling that bubbling of the environment to be able to test it and ensure that there is no cross-contamination. That added feature, on top of the fact that it can do it so much faster than what Rubrik could, was the compelling reason why we looked there.

Along the way, I looked at Cohesity and Veeam and a few other vendors, but they didn't have an elegant solution or an elegant way of doing what I wanted to do, which is sending copies to an expensive cloud storage target, and then having the mechanism to instantiate them. The mechanism wasn't as elegant with some of those vendors.

What other advice do I have?

We initially started with the on-premises version, where we replicated our global DR from the US to Taiwan. Zerto recently came out with a cloud-based, enterprise variant that gives you the ability to use it on-premises or in the cloud. With this, we've migrated our licenses to a cloud-based strategy for disaster recovery.

We are in the middle of evaluating their long-term retention, or long-term backup solution. It's very new to us. In the same way that Veeam, and Rubrik, and others were trying to get into Zerto's business, Zerto's now trying to get into their business as far as the backup solution.

I think it's much easier to do backup than what Zerto does for DR, so I don't think it will be very difficult for them to do table stakes back up, which is file retention for multiple targets, and that kind of thing.

Right now, I would say they're probably at the 70% mark as far as what I consider to be a success, but each version they release gets closer and closer to being a certifiable, good backup solution.

We have not had to recover our data after a ransomware attack but if our whole environment was encrypted, we have several ways to recover it. Zerto is the last resort for us but if we ever have to do that, I know that we can recover our environment in hours instead of days.

If that day ever occurs, which would be a very bad day if we had to recover at that level, then Zerto will be very helpful. We've done recoveries in the past where the on-premises restore was not healthy, and we've been able to recover them very fast. It isn't the onesie twosies that are compelling in terms of recovery because most vendors can provide that. It's the sheer volume of being able to restore so many at once that's the compelling factor for Zerto.

My advice for anybody who is implementing Zerto is to get a good cloud architect. Spend the time to build out your design, including your IP scheme, to support the feature sets and capabilities of the product. That is where the work needs to be done, more so than the Zerto products themselves. Zerto is pretty simple to get up and running but it's all the work ahead in the deployment or delivery that needs to be done. A good architect or cloud person will help with this.

The biggest lesson that I have learned from using Zerto is that it requires good planning but at the end of it, you'll have a reasonable disaster recovery solution. If you don't currently have one then this is certainly something that you should consider.

I would rate Zerto a ten out of ten.

Ensures that we have the most up-to-date information in the case a disaster occurs
Pros and Cons
  • "My organization has experienced the benefits of using the tool, which include the ability to test our disaster recovery quickly."

    What is our primary use case?

    The primary use case for Zerto in my company is to manage disaster recovery.

    How has it helped my organization?

    My organization has experienced the benefits of using the tool, which include the ability to test our disaster recovery quickly.

    What is most valuable?

    The most valuable feature of the solution is the constant synchronization, ensuring that we have the most up-to-date information should a disaster occur and we need to handle failovers.

    Zerto's near-synchronous replication is why we first acquired the product.

    Zerto's overall effect on our RPOs is such that it improves them significantly, and it is the reason why we purchased the product. Rather than having to recover from backup, which is time-consuming, it is available instantly.

    If I compare the speed of recovery with Zerto versus the speed of recovery with other disaster recovery solutions, Zerto is at least five times faster than other products.

    What needs improvement?

    It turns out that my organization has not been using all the capabilities of Zerto and we just found from the session, HPE Discover'24, that the things we were looking for already existed within Zerto. I don't have anything to ask for improvement in Zerto.

    I don't want any additional features in the product as I would be busy employing the functionalities I recently found out are available in the solution.

    For how long have I used the solution?

    I have been using Zerto for seven years.

    What do I think about the stability of the solution?

    The tool is very stable.

    What do I think about the scalability of the solution?

    The scalability is fine for our company. We are a relatively small organization, but it has done everything we needed.

    How are customer service and support?

    The solution's technical support has been solid and very good, and we hope it stays that way under HPE.

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

    In our company, we would recover from our backup software, so things depended on whatever backup tool was used at the time.

    How was the initial setup?

    When it comes to the product's initial setup phase, Zerto's support has been very strong and relatively straightforward.

    What was our ROI?

    I have experienced a return on investment from the use of Zerto. The exercises associated with disaster recovery are faster and we are able to save time now in our company.

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

    Fortunately, the tool's pricing and licensing are not a concern for me at the moment. Other teams handle it.

    Which other solutions did I evaluate?

    The evaluation of other solutions against Zerto was pretty quick. In our company, after we saw a Zerto in use, we couldn't find anything else like it in the market.

    What other advice do I have?

    I have used Zerto to protect VMs in our company's environment.

    Considering that there is always someplace to go from where our company is currently, I rate the tool a nine out of ten.

    Fast, cost-effective, and easy to manage
    Pros and Cons
    • "It is cost-effective and stable. It protects virtual machines, and there is a fast recovery time."
    • "One thing I would like to see in their roadmap is introducing long-term storage in the cloud such as Azure or AWS. They can make it more seamless."

    What is our primary use case?

    We are using Zerto for disaster recovery. By implementing Zerto, we wanted fast recovery time.

    How has it helped my organization?

    It helps to meet recovery point objectives. Management is simplified. Its automation capabilities simplify the management of the disaster recovery processes.

    It reduces the burden on the IT staff. It is also cost-effective. We could realize its benefits only in eight months.

    Disaster recovery through the cloud is very important for our organization. We want to ensure that we are able to retrieve data in a proper manner.

    Zerto helps to protect VMs in our environment. It replicates a lot quicker than what we were using previously. There is a reduction in the time taken to replicate. It takes a quarter of the time and protects our VM environment.

    Zerto has been very good for our RPOs. It has been within seconds for us. It has also helped us to meet our RTOs.

    It is easy to migrate data. We have not had any challenges. Zerto provides the ability to keep our users collaborating with one another during a data migration. It is very useful for a smooth migration process. 

    Zerto helped to reduce our organization's DR testing. It saved three to four hours. 

    Zerto has reduced the number of staff involved in overall backup and DR management. Instead of ten people, we now have seven people.

    What is most valuable?

    It is cost-effective and stable. It protects virtual machines, and there is a fast recovery time.

    It works well. It is simple to set up. It works a lot quicker than what we were using previously. It takes about a quarter of the time. It is important for our organization.

    What needs improvement?

    One thing I would like to see in their roadmap is introducing long-term storage in the cloud such as Azure or AWS. They can make it more seamless.

    The downtime features can also be improved.

    For how long have I used the solution?

    I have been using Zerto for one and a half years.

    What do I think about the stability of the solution?

    It is stable.

    What do I think about the scalability of the solution?

    It is scalable. It can scale based on the growth of the organization.

    We have about 25 people using this solution. It is being used in multiple regions.

    How are customer service and support?

    Their customer support is good. I would rate them a ten out of ten.

    How would you rate customer service and support?

    Positive

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

    We were using the disaster management solution of AWS. We switched to Zerto because of cost management and recovery point objectives. They were offering real-time replication and automation to help our organization achieve its RPOs and RTOs. We wanted better recovery time. 

    Zerto is also easier to use than other solutions.

    How was the initial setup?

    Its initial setup is good. Its implementation took one month.

    It is easy to maintain.

    What about the implementation team?

    We had support from Zerto.

    What was our ROI?

    We have definitely seen a return on investment.

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

    It is cost-effective.

    Which other solutions did I evaluate?

    We did not evaluate other options.

    What other advice do I have?

    I would recommend Zerto to others. I would rate Zerto a nine out of ten.

    Which deployment model are you using for this solution?

    Replicates and recovers within minutes and enables our growth
    Pros and Cons
    • "There are a lot of valuable features. The basics of what it does to replicate and recover things within minutes is awesome. It's far above anything that any of the competition has. We offer other disaster recovery software but primarily use Zerto for recovery times and the number of recovery points because of how fast and easy it is. It's so much better."
    • "The problem with the backup product is that it's not very mature and you really need a specific use case to be able to use it effectively. It's hard to explain to our customers, especially our large customers, that the use case is so limited."

    What is our primary use case?

    Our primary use case for Zerto is for disaster recovery. In the last few versions, they've offered backup, but we don't use it because it's not nearly as robust as what most of our customers are looking for. We also use it for migrations too, to migrate customers into our cloud, and things like that. But that's around 20% of our use case.

    How has it helped my organization?

    Zerto has enabled our growth. Five years ago we had around 20 customers and now we have 500. We protect around 15,000 VMs now.

    What is most valuable?

    One of the most valuable features is the analytics portal. It's still an evolving feature and has ways to go but we use that for monitoring because we have hundreds of sites. It's nice that all the alerts and everything is consolidated into that one site because we used to have to make sure that we were connected to many, many sites to make alerting work, which was a nightmare. 

    Our alerting is done through scripting too. They do have pre-canned alerting through but is not very robust and they're working on it. They actually included us in the study on it. For instance, if you were to have a problem at a certain site or something, there's no way that you could take it out of monitoring. If you were using their system, it would just flood you with alerts from all kinds of stuff from the site if it was down. It is great if a site is down and you don't expect it, but if you have planned maintenance, you don't want all of this coming in.

    There are a lot of valuable features. The basics of what it does to replicate and recover things within minutes is awesome. It's far above anything that any of the competition has. We offer other disaster recovery software but primarily use Zerto for recovery times and the number of recovery points because of how fast and easy it is. It's so much better.

    We reduced the number of people involved in recovery situations by using Zerto. We had another solution before and we had a small number of customers and it took the whole team to manage 20 customers. Now we have 400 to 500 customers and our team is relatively the same size. We're broken up into different teams, but when we managed it all ourselves with only 20 customers, we had four people. And now we have around 500 customers and we have around 20 team members.

    What needs improvement?

    Zerto has a really robust PowerShell and scripting that you can get lots of numbers out of but it's not exactly the easiest thing to do. Zerto has a few nice pre-canned reports but there is a need for more. Unless you script something, it's difficult to go in, click a button, and see the information that you may be looking for.

    The problem with the backup product is that it's not very mature and you really need a specific use case to be able to use it effectively. It's hard to explain to our customers, especially our large customers, that the use case is so limited.

    Zerto is very easy to use on the surface, especially if you're an enterprise customer, which is just like A to B replication or one site to two sites. As a cloud provider, they still have a lot of work to do. But for most customers, it would be fantastic. We have a lot of private clouds that are one site or two sites. So when it's not meshed like our larger environment is, it works fantastic. But when you get into the overall fully meshed model with vCD integration that we have, it doesn't work as well. I think Zerto is mostly concentrated on the enterprise customer and left the cloud providers by the wayside.

    With the HP acquisition, product development has certainly accelerated. They recently released the first major half release and have put additional focus on cloud providers. Unfortunately, the major focus remains on Enterprise. Next year, they will force customers to move from Windows management VMs to Debian Linux. I can only hope they have a well-thought-out migration tool. My fear is that the cloud provider will be a secondary thought once again.

    The major issue with Zerto development is that they refuse to patch the current software release and only patch the newest release. When you hit the bug, they expect you to upgrade right away. This is not an issue if you only have a hand full of sites. The issue when you have 100s is that there is no way to skip a minor release. Every multi-tenant customer you have must be upgraded to every minor release. Two to three upgrades every year for every customer is very intrusive and requires way more management effort than should be necessary. We often have a hand full of customers delaying the upgrade cycle and are forced to discontinue service to those customers. HP can surely develop a better model.

    For how long have I used the solution?

    I have been using Zerto for six and a half years. It's deployed on-premises, on the cloud, and we use it as a SaaS offering. We are the cloud provider. We also integrate with AWS and Azure.

    What do I think about the stability of the solution?

    It's a very stable solution, for the most part. They have a new release every six months and some releases are better than others as far as bugs. Sometimes those bugs have to do with something in Hyper-V, and sometimes they have something to do with VMware or vCenter. But many times, it's directly related to Zerto's problems. Usually, their major releases go in .0 and .5. The .0 releases have the new features in them and they're more buggy and the .5 releases are more stable.

    What do I think about the scalability of the solution?

    It's extremely scalable, in a small sense, but the problem is when you get very meshed, with 10 sites replicating to 10 sites, and each one of them is meshed in to be able to replicate it to the other one. Then scalability starts to become problematic.

    The big thing is, we have a cloud manager that manages all our ZVMs, which enterprise customers probably wouldn't have. You can only upgrade half a release for each upgrade. So you couldn't go from Zerto 6 to Zerto 7. For instance, you have to go to 6.5 and then go to seven.

    Trying to upgrade is not easy because every customer that's paired and replicating into those sites has to upgrade it in those steps. It takes us several months, twice a year, to get everybody upgraded. They have a portal called Cloud Control which makes things better as far as upgrades, but they recently broke it with version 7.5 by adding encryption. So it was useless. We just upgraded to a version in which it should be working again, so the next time we're going to try to use Cloud Control to upgrade. Hopefully, it will be better. We only really have one round of upgrades through Cloud Control to get an idea of how well it worked. 75% of the time, those upgrades work without problems.

    How are customer service and support?

    There was a time when they had customer service people just taking tickets and they couldn't really help you at all, which was terrible. Now, they have a level-one level-two-type model. The level-one guys are getting better, but as they grow, it can be difficult. 

    All of our engineers are certified and we would like to go straight to level two. A lot of times we waste a lot of time with level one, and then they put the ticket in the queue for level two. So it takes another day to get to level two unless we're really loud and escalating the ticket right away. The biggest problem that we have with Zerto is getting to level two. 90% of the time, because of our knowledge, level one is not useful to us. Although, it probably would be to the average customer. 

    Zerto really needs support dedicated to CSPs and large customers.

    How would you rate customer service and support?

    Positive

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

    We switched from our previous solution because Zerto was so much easier than everything else that we saw. We have a team that does the tests. It was a pretty easy choice to move away from those platforms at the time and those platforms no longer exist. Today there are many alternative DRaaS solutions and we offer many of them. Zerto remains more mature and feature-rich than the competition though.

    How was the initial setup?

    The initial setup was pretty easy. You have to have connectivity between the sites that you're replicating, your production, and then your DR site or sites. Getting that connectivity is the biggest thing. Once that connectivity is there, it's fairly simple. You deploy Windows VM, put a small software package on it, and then pair the two. You do the same thing at the recovery site and once those sites are able to talk. In VMware, you install a VM on each ESX host that you need to replicate a VM on. Then you create a policy to do that replication. The replication policies work very well. Re-IP on failover if problematic.

    The network connectivity takes the longest. It can take weeks, depending on what you have to do to connect the sites. It could be a couple of hours if you're just setting up a VPN. If you're putting in a circuit, it could take a very long time. That's the X factor with it, but assuming that's already there, within an hour you could be replicating data from one site to another.

    ZCCs remain a major stumbling block. If the routing table has issues, the only fix is to delete all protection, redeploy the ZCC and rebuild. Again, avoid Zerto Cloud Manager until the product matures.

    What about the implementation team?

    We implemented the solution in-house.

    What was our ROI?

    We have seen an ROI. Otherwise, we wouldn't keep using it. The biggest thing is the number of VMs we can support with the staff that we have. 

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

    The licensing is fair. We have an enterprise license in which Zerto gives us 20,000 licenses or something well above what they think we're going to sell for the year. Then all our customers pull from that pool and we resell the licenses. We may sell 50 licenses to a customer but at the start of their contract, they may only have 30 VMs ready for DR. We contract them for 50, but eventually, they'll get up to 50. So we don't have to go to the vendor and add and remove one license here or one license there all the time.

    That part of it is easy, but we do have to license all of our sites once a year, which is a pain and all of our sites report to Zerto Analytics. I've been asking them for years since they started Zerto Analytics, why we can't just put our license key on analytics rather than logging into hundreds of sites and putting them in each site. That's a real beast. They definitely need to fix the part where the site licensing is terrible. As far as the licensing VMs to replicate, that's great.  In version 9, Zerto plans on deploying a license server to address this.

    Zerto 9 is out and there is still no customer-deployable license server. We regularly have issues with customers who cannot reach the Zerto license server. They cut you off at the knees after 14 days! HP really needs to work on this process.

    Which other solutions did I evaluate?

    Commvault was one of the big ones we looked at. Commvault is much more complex and expensive. We also looked at AWS and Azure. We offer a wide range of solutions. 

    Recently launched last year, Nutanix LEAP is primarily designed for people that use Nutanix, and not everybody does. Not everybody can use it. We also offer RecoverPoint for VMs. It is a Dell EMC product, so it's geared toward people that are running VxRail. And then there is vCloud Availability. You have to have vCloud Director on both sides and vCenter, which is not something that everybody has either. vCloud Availability monitoring is also a nightmare. Zerto is more the product of choice for most use cases. 

    What other advice do I have?

    Some of the biggest problems that we've had as a cloud provider are the vCD integration and the Zerto Cloud Manager integration. If you can avoid those two things, avoid them.

    I would rate Zerto an eight out of ten. 

    Which deployment model are you using for this solution?

    An easy-to-use solution that reduced our downtime and improved performance
    Pros and Cons
    • "The way we can use checkpoints from each VM to restore them is an excellent feature, and the replication is great."
    • "The solution is very expensive."

    What is our primary use case?

    Our primary use case currently is for replicating virtual machines on a production site and for backups. We also use it for onsite cloning, and we have a license that enables us to do that.

    We don't use Zerto in the cloud at the moment. 

    How has it helped my organization?

    The tool gave us a better way to respond to any problems on the production side and improved how we can recover. The recovery capability is the best part of Zerto.

    The solution reduced our recovery time objective (RTO) and improved performance on the IO by around 10%. When we implement failovers and synchronization to VMs with databases, we see a marked increase in performance.         

    The solution helped reduce our downtime. Before we implemented Zerto, my organization did a recovery that took four hours. Since implementing, the last time we did a recovery, it took one hour, so the solution makes recovery significantly faster. The cost of three hours of downtime to my company would be very high.   

    What is most valuable?

    The way we can use checkpoints from each VM to restore them is an excellent feature, and the replication is great.

    Zerto is easy to use, and it saved us five times in three years; on those occasions, we had problems with our VMs, and we used the product to roll back to a functional state or for failover, which resolved our issues. 

    Regarding near-synchronous replication, Zerto is the best application we have right now. We could get another solution to do the same job, but from a design point of view, Zerto is an excellent tool for replication and synchronization, and we don't have a problem with it.

    What needs improvement?

    The IT could be better; we have sectioned areas and databases for iOS, Windows, and Linux. Because the solution is centralized, each computer has the VMs from every section running.

    The solution is very expensive. 

    For how long have I used the solution?

    I've been using Zerto for three years. 

    What do I think about the stability of the solution?

    Zerto is highly stable, and I rate it ten out of ten for stability. 

    What do I think about the scalability of the solution?

    We didn't have to scale the solution, so I can't speak to the scalability. 

    How are customer service and support?

    I give the technical support full marks; it's simple to open a case and get a quick response from the support staff. We rarely experience issues requiring us to contact support as it is.

    How would you rate customer service and support?

    Positive

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

    We didn't previously use another solution of this kind. 

    How was the initial setup?

    The initial setup was straightforward; it wasn't complex at all. It was very simple to install and set up the replication, more so than other solutions. 

    The replication functionality is very user-friendly, so that was the easiest part. At the same time, the security aspect of the solution, integrating with our firewalls etc., was the most challenging element of the deployment.

    What about the implementation team?

    We carried out the implementation via an in-house team. 

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

    The cost is one of the only drawbacks of Zerto because it's very high, and the overall impact of the solution on our organization is relatively low. This is why we are trying to figure out if another product could fulfill the same role for cheaper.

    Which other solutions did I evaluate?

    We are currently evaluating Veeam, and how that would fit into our system, as many of our clients use it, so we wonder if it may be a better option for us.

    What other advice do I have?

    I rate the solution ten out of ten. 

    My advice to potential customers is to carefully determine the requirements for such a solution and how Zerto fulfills those. Some solutions do the same job for cheaper, so considering the price has to factor into the cost-benefit analysis.

    Which deployment model are you using for this solution?

    On-premises

    Is easy to use, has a faster recovery speed, and saves time
    Pros and Cons
    • "Zerto saved us a lot of money compared to the cost of replicating at the LUN level. It also really simplified it and gave us shorter RTOs and RPOs."
    • "Without Zerto, we would have been in serious trouble, so it definitely returned the investment many times over."
    • "I would like to be able to replicate one to multiple without having to recreate every VPG. That would save us a lot of time. When we add a site or move our DR to a different site, I have to recreate everything from scratch. So, it'd be cool to be able to just repoint an existing VPG to a new site without having to recreate everything."
    • "I would like to be able to replicate one to multiple without having to recreate every VPG."

    What is our primary use case?

    We use Zerto to replicate to a cloud center.

    How has it helped my organization?

    Zerto saved us a lot of money compared to the cost of replicating at the LUN level. It also really simplified it and gave us shorter RTOs and RPOs.

    What is most valuable?

    We got hit with ransomware about three years ago, so we had to do a full recovery with Zerto. The recovery is the best feature.

    When you compare the ease of use of Zerto versus that of SAN, Zerto is a lot easier because you can do it at the actual virtual machine level versus doing the whole LUN. In the latter case, in the event of a recovery, you would have to recover the whole LUN and see what's in there. It is a lot easier to do any operation with Zerto.

    We were hit with ransomware about three years ago, and the amount of time that it took us to recover from that with Zerto was weeks less than it would've taken us with our previous DR solution.

    When you compare the speed of recovery with Zerto versus the speed of recovery with other disaster recovery solutions, Zerto is a lot easier and faster because you can choose what to recover and when. In the event of a disaster, for instance, you can recover your most important stuff first.

    Zerto certainly reduced the staff involved in a data recovery situation. It's so easy to use that one person can do it all in those events. You won't need a guy from the VMware team and another from the storage team. It's all done at the DM level, so, it's easier to recover without having to involve other teams. With our previous solution, we would have needed three to recover, and I was able to do it all myself with Zerto.

    It absolutely helped to reduce our organization's DR testing because it's so fast and easy to test without disrupting anything. We can choose what to test, more critical versus noncritical, and how frequently we want to test. About 75% of that saved time is allocated to value-added tasks.

    What needs improvement?

    I would like to be able to replicate one to multiple without having to recreate every VPG. That would save us a lot of time. When we add a site or move our DR to a different site, I have to recreate everything from scratch. So, it'd be cool to be able to just repoint an existing VPG to a new site without having to recreate everything.

    For how long have I used the solution?

    We started using Zerto in mid-2018.

    What do I think about the stability of the solution?

    We haven't had any issues with stability. It's always up and running. Whenever there's an issue at the DM level that affects it, it'll give an alert.

    What do I think about the scalability of the solution?

    It seems like Zerto would be good for a big environment. Ours is small and doesn't really grow a lot; the size stays static. However, having worked with it for a few years I wouldn't be worried to use it in a bigger environment.

    How are customer service and support?

    Zerto's technical support is good. Whenever we have issues, which is rare, they are fast to respond. When we had our major issue, I had a lot of calls with them, and we had to work around the clock. They did a good job of passing us through every time zone and keeping us engaged with someone. I would rate them a ten out of ten.

    How would you rate customer service and support?

    Positive

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

    We used the snapshot and replication of our SAN that we used to have. It wasn't necessarily a true DR replication tool, but it would do a snapshot and then put a copy of that snapshot somewhere else. That was our DR plan before switching to Zerto.

    How was the initial setup?

    The initial setup was really easy and fast. We had it installed in less than an hour, maybe even half an hour. After that, we created our groups. The time for that would depend on how many DMs you have, but it's easy and intuitive.

    What about the implementation team?

    We had someone from Zerto walk us through the installation and setup. They explained every step as we went through it, and it was excellent.

    What was our ROI?

    We certainly have seen an ROI. When we got hit, we saved a lot of money because we were able to recover RBMs. Without Zerto, we would have been in serious trouble. So, it definitely returned the investment many times over.

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

    The pricing is pretty competitive to that of other options out there. When we shopped around, it was in line with the price of other solutions.

    Which other solutions did I evaluate?

    We looked at Veeam and Avamar. At that point, Zerto was the only one that did CDP, and that was the reason we went with Zerto.

    What other advice do I have?

    On a scale from one to ten, I'd rate Zerto a ten.

    Scalable solution that reduces downtime during migrations
    Pros and Cons
    • "The ease of use and simplicity in moving things without having to do a cross-v set of V-motions has been most valuable. It saves time and effort and it eliminates mistakes."
    • "The speed of recovery with Zerto is at least five to ten times faster, helping us reduce downtime during migrations that would have cost our company millions."
    • "The licensing is confusing and complicated."

    What is our primary use case?

    Our main use case for this solution is the data center migration. We are in the process of moving from our legacy data center and all the VMs into our new data center.

    In the future, we would like to look more into disaster recovery using Zerto but that's a much longer process and we are still looking into it.

    How has it helped my organization?

    The speed of recovery with Zerto is at least five to ten times faster. It helped us reduce downtime during migrations. There would've been a lot more downtime had we done a standard migration across data centers, powering everything down. This downtime would have cost our company millions.

    What is most valuable?

    The ease of use and simplicity in moving things without having to do a cross vCenter V-motions has been most valuable. It saves time and effort and it eliminates mistakes. This project would've been years if not for Zerto. We completed it in months instead of years.

    What needs improvement?

    The licensing is confusing and complicated.

    For how long have I used the solution?

    I have been using this solution for two years.

    What do I think about the stability of the solution?

    This is a stable solution. 

    What do I think about the scalability of the solution?

    This is a scalable solution. We used it for our biggest data center and it handled it just fine. We haven't personally had to scale it up, but if we needed to, we definitely could.

    How are customer service and support?

    Support has been pretty good. I would rate it a nine out of ten. 

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

    I personally have not used other solutions other than just what's built into VMware. When comparing the VMware native solution versus Zerto, it's night and day. It's much simpler and straightforward to set up.

    How was the initial setup?

    The initial setup is straightforward. It is streamlined with simple instructions. Anybody can do it as long as they understand their infrastructure.

    What about the implementation team?

    We had a contractor that we brought in to help us with it. 

    What was our ROI?

    We have seen return in our investment with Zerto due to the speed and usability and being able to do this huge project with limited hiccups.

    What other advice do I have?

    I would advise others that the cost of this solution is justified based on the value you receive. 

    I would rate Zerto a nine out of ten. 

    Which deployment model are you using for this solution?
