We were able to migrate from co-lo to on-prem without losing any time
Pros and Cons
  • "Moving the VPGs from one location to another is a valuable feature. You just click on it and move it and it's done."
  • "If there is a mass of changes to a server, Zerto will restart the replication. It would be nice to know why that happens."

What is our primary use case?

We use it for DR and general backup. We have snapshots or shadow copies with Microsoft and we do Zerto backups to our other locations so we can always get the data back.

How has it helped my organization?

We bought Zerto, in the beginning, to migrate a very important system of the airline from a co-lo that was managed by the colo to our on-prem. As an airline, you can't be down because you could cause a ground stop. With Zerto, we were able to migrate all those things across to on-prem without touching anything or losing any time. We took very little downtime.

Also, we've run into some situations where, for some reason, Windows has lost some of the files. I have been able to fail it over to our other data center and they were back up in 10 minutes.

The speed of recovery with Zerto versus other disaster recovery solutions is vastly better. Whereas with the others, I'd have to spin through a lot of stuff and find things, with Zerto I can scroll back in the GUI, find the one I want, and restore it. If that's not right, I can destroy it and go back a little bit more in time.

And our being an ultra-low-cost airline, we don't have staff, so it helps in that way.

It has also helped our DR testing because we can fail over the main part that runs the airline within 45 minutes. The first time, it took me an hour and a half. The second time, it took about an hour. The last time I did it, it took about 45 minutes. That's within the timeframe of one hour where we don't have to do a ground stop.

What is most valuable?

Moving the VPGs from one location to another is a valuable feature. You just click on it and move it and it's done. We have a stretch VLAN between our data centers so it's really easy: this is IP here and the same IP is there. So if something happens or somebody wants to test something, I can fail it over.

Another aspect that I use a lot is that I can fail it over into its own little bubble and I can install software that I want to test to make sure it doesn't break something. I can do that and then roll it all back.

What needs improvement?

If there is a mass of changes to a server, Zerto will restart the replication. It would be nice to know why that happens. 

The other thing that I've run into lately is that when I've done a whole bunch of upgrades to systems, so they're offline, they get stuck in a pending state. You can never get them out so you have to delete and start all over again. It would be nice if they could make it a little simpler to figure out what's wrong.

Learn what your peers think about Zerto. Get advice and tips from experienced pros sharing their opinions. Updated: May 2023.
708,461 professionals have used our research since 2012.

For how long have I used the solution?

I have been using Zerto for about six years.

What do I think about the stability of the solution?

It always just runs. I don't have to worry about it or keep checking it. It just does its thing.

What do I think about the scalability of the solution?

It's very scalable. Fortunately, we bought a bunch of licenses when we first bought it and we've been growing into those licenses over the years. It has been very scalable for us.

How are customer service and support?

The technical support has been good, although I've had a couple of situations where they've said some things that were totally inaccurate. But you have that in all organizations.

How would you rate customer service and support?

Positive

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

Since I started with this airline, we have gone through two other solutions. Zerto is the third and we've stuck with it for quite a few years.

One of the other solutions was a direct product that dumped everything to a storage area in the cloud and it never was consistent. The other was a Dell application backup that no longer exists. That was just too limiting and its backup was never consistent.

Zerto is much easier to use. Once you get the concept down of what it's doing, it's really easy to bring up backups, restore backups, move things around, and test things. It's very easy.

What about the implementation team?

I had one of their sales reps in Colorado help me through the setup. Then we just took it over.

What was our ROI?

The ROI is in "funny money." It's my time and how long something is down or how long it takes somebody to restore something, and that is much faster.

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

The pricing seems really good. We're an enterprise customer, so we get all the bells and whistles.

Which other solutions did I evaluate?

We evaluated a couple of things, but one of our co-los was actually using Zerto so we looked at it as a result. That is what led us to buy it.

Reduced downtime for several of our customers, saving them significant associated costs
Pros and Cons
  • "Journaling is by far the most valuable feature. We have used it several times for customers who have gotten ransomware and had to do a rollback. Having the right time period was important. Some of them had their backups encrypted. So, they didn't encrypt the Zerto machine seven days previously, and we were able to bring that back up."
  • "From the relationship standpoint, we have never had a local rep in South Bend, Indiana. It has always been somebody in Boston, and there is not a lot of communication. That is one of the big things. We would like help driving the business and talking to our sales people as well as more involvement from them. We could really utilize it more, drawing more customers in, but we need help with that."

What is our primary use case?

We have customers who come in for DR as a service, but we also do inter-cloud DR.

How has it helped my organization?

It has brought customers into our cloud, since this was a barrier to get in. We have used the migration model a lot to bring customers in. We just brought in a customer from Microsoft Hyper-V into our VMware file. That would have been a difficult challenge if we did not have Zerto as a tool.

Zerto has helped to reduce downtime with several customers. For example, we had a customer who had many of their VMs encrypted. They had about 40 to 60 terabytes worth of data. To recover that from backup would have taken days. We were able to bring them up at the DR site, getting them up and running, within hours. This would have cost the customer millions if they had been down. As a title company, if they would have been down, that would have disrupted a whole title industry, where people are trying to buy houses. If you can't get the title for the house, then you can't move forward. Other people wouldn't have been able to sell their house. There would have been a ripple effect. So, that was huge.

It has definitely helped our customers reduce their DR testing. We can do failover tests live in the middle of the day and generate a report, and they are comfortable with it. 

What is most valuable?

Journaling is by far the most valuable feature. We have used it several times for customers who have gotten ransomware and had to do a rollback. Having the right time period was important. Some of them had their backups encrypted. So, they didn't encrypt the Zerto machine seven days previously, and we were able to bring that back up.

For how long have I used the solution?

I have been using Zerto for about seven years.

What do I think about the stability of the solution?

It is very stable.

What do I think about the scalability of the solution?

It is very scalable. All the workloads go on hosts. So, in order to grow, you will need to have more hosts anyway.

How are customer service and support?

From the relationship standpoint, we have never had a local rep in South Bend, Indiana. It has always been somebody in Boston, and there is not a lot of communication. That is one of the big things. We would like help driving the business and talking to our sales people as well as more involvement from them. We could really utilize it more, drawing more customers in, but we need help with that.

I would rate the technical support as seven out of 10. Where it becomes difficult is if Tier 1 can't help you, then it takes a long time to get to Tier 2 or the development side, if something is beyond their capabilities.

How would you rate customer service and support?

Neutral

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

We use VMware High Availability, which is one of the options in our cloud. It is a less expensive option. So, we have customers who want that. Also, we have tried Veeam Backup & Replication, which is not cloud-native, so we don't use that. However, a company, whom we acquired, was using it. So, we tried it out.

Zerto is a lot easier to use. It has a lot more features, as far as orchestration, than VMware High Availability. The reallocation of IPs and the networking part of it are not that great in VMware High Availability. Plus, the retention that you get with Zerto is better than High Availability. Veeam didn't get into that much, and there is no orchestration into the cloud. 

How was the initial setup?

The initial setup is very straightforward. The wizard that you run through is just very straightforward. If it is a DR-as-a-service customer on my end, then I am just deploying it as sort of a cloud connect, which is very easy.

What about the implementation team?

I deploy it for all our customers.

What was our ROI?

We have absolutely seen ROI. Over time, we make money off of the CPU, RAM, and storage of Zerto usage. We benefit that way.

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

In a world where others are catching up, e.g., VMware High Availability, there needs to be a less expensive option as well. When a customer has approximately 100 VMs, if you multiply by 40, we aren't charging a very high margin on it at all since the license is so expensive. We feel their pain. That is the most expensive part of it. The storage, CPU, and RAM are a lot less. It is the licensing that is really expensive. Whereas, with an option like VMware High Availability, it is a couple dollars per month. That is our spend that we are charged by VMware, then our margin is higher on those VMs. Giving us some ability to have higher margins, as an MSP, would be a good thing.

What other advice do I have?

I would rate Zerto as nine out of 10.

Makes it easier to do failovers, is stable, and is straightforward to set up
Pros and Cons
  • "I like that the failover is simple and that it's a stable platform. It makes it easy for us to do failovers in the event that we have an issue. It also makes it easier to do test failovers because we can test it prior to actually doing a real failover. This means that we can pull things back or commit them over on the other side. Zerto streamlines the process instead of having to have a whole team of people who are dedicated to disaster recovery."
  • "We're an NSX-T shop, and if I could get an NSX-T integration where it could manage the networks a little tighter, that would be an improvement."

What is our primary use case?

Our use case is disaster recovery or failover. It makes it a lot easier for us to actually test DR because of some of the coordination and orchestration that are a part of Zerto. However, our use case is strictly DR, making sure that we have the right RPOs, and Zerto does a good job of handling that.

How has it helped my organization?

Zerto improved a lot of the processes that we do for disaster recovery. It makes it a lot easier when we talk to our upper management and letting them know that we have a way of getting data from one data center over to another data center without a whole lot of friction.

What is most valuable?

I like that the failover is simple and that it's a stable platform. It makes it easy for us to do failovers in the event that we have an issue. It also makes it easier to do tests of failovers prior to actually doing a real failover. This means that we can pull things back or commit them over on the other side. Zerto streamlines the process instead of having to have a whole team of people who are dedicated to disaster recovery.

When you compare the ease of use of Zerto versus that of SRM, it's a night-and-day difference. SRM was very kludgy to set up when we implemented it. Zerto was a lot more streamlined from that perspective. SRM wasn't very stable for us, sometimes it would work, and sometimes it wouldn't. With Zerto, we rarely have any issues that can't be fixed with a phone call. It doesn't require a full rebuild, and the upgrades are simpler. It's just a better solution all around.

We don't have a whole lot of downtime, to begin with. When we've had issues, Zerto has allowed us to move the workloads quicker. I would say from a configuration perspective, Zerto saved us quite a bit of time over SRM. Zerto is a set-it-and-forget-it type of tool. We get into it only when we need to.

When you compare the speed of recovery with Zerto versus the speed of recovery with other disaster recovery solutions its fairly quick. We can failover a workload from our headquarters to our DR facility and have it up and running in 10 or 15 minutes, which is pretty good. A five-minute migration is also a nice feature.

Zerto hasn't reduced the staff involved in a data recovery situation because we're a fairly thin IT assistance team. However, with Zerto, we don't have to plan ahead for additional resources just for an eventual or potential failover.

When we do regular disaster recoveries, where we do a full failover and test in our DR facility for a couple of days, Zerto makes it a lot easier to move it from one place to another and make the VM agnostic to the datacenter.

What needs improvement?

We're an NSX-T shop, and if I could get an NSX-T integration where it could manage the networks a little tighter, that would be an improvement.

The other improvement is working with storage vendors, like Pure Storage for the synchronization of the data similar to what SRM does. Using Zerto for the orchestration, and the hardware vendor for the replication would be beneficial.

For how long have I used the solution?

I have been using Zerto for about three years.

What do I think about the stability of the solution?

The stability is very good. It's rare that we have a complete outage. Sometimes, we have a VPG that doesn't replicate correctly, but a call to tech support gets it resolved.

What do I think about the scalability of the solution?

Right now, we have about 120 VMs that are being replicated, and we have an eight-second RPO. I consider that good performance for our workloads. I know we could scale out easily using our current configuration.

How are customer service and support?

Zerto's technical support is very strong. When we have an issue, it gets resolved quickly. We have never had an issue with Zerto's support.

We've had good experiences with all of the engineers that we've worked with, so on a scale from one to ten, I would rate them at nine.

How would you rate customer service and support?

Positive

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

We used SRM previously, and it wasn't very good. We ended up having to rebuild it a few times.

How was the initial setup?

The initial setup was fairly straightforward. Everything made sense, and after a couple of days, we were up and running.

What about the implementation team?

We had an engineer from Zerto help us with the implementation.

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

I think the cost is reasonable for VM licensing. It's not outside the scope of an enterprise product.

What other advice do I have?

On a scale from one to ten, I would rate Zerto at nine.

Which deployment model are you using for this solution?

Continuous streaming keeps us up to date a lot faster
Pros and Cons
  • "The most valuable features are the continuous streaming, that it takes very little CPU usage — it doesn't affect production — and the recovery time is very short."
  • "With the VPG (virtual protected group) it would be nice if you could pick individuals in the grouping instead of having to failover the whole group."

What is our primary use case?

It is controlling our mission-critical production system as a backup and a failover.

How has it helped my organization?

Zerto has taken us from being able to do a failover in four to six hours down to one to two hours.

What is most valuable?

The most valuable features are

  • the continuous streaming
  • that it takes very little CPU usage — it doesn't affect production 
  • the recovery time is very short.

What needs improvement?

With the VPG (virtual protected group) it would be nice if you could pick individuals in the grouping instead of having to failover the whole group. 

Other than that, it's a pretty good product.

For how long have I used the solution?

I have been using Zerto for about a year.

What do I think about the stability of the solution?

It's very stable.

What do I think about the scalability of the solution?

I don't see a problem with scaling it at all. They could improve setting up for SQL clustering or for SQL Always On. It really is set up for a one-to-one and not for a multiple solution. They could work on that.

We will probably increase our usage in the future. Right now we have a license for 15 VMs through Zerto and we are only using 10.

How are customer service and support?

We haven't worked with Zerto's technical support other than during deployment. Everything seems to be running really well now. During deployment, their support was very responsive. It's just that they did not have a good solution that worked with VMware and Nimble.

How would you rate customer service and support?

Positive

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

We were using Veeam. We switched to Zerto because it has continuous streaming that would keep us up to date a lot faster. Veeam kept promising they were going to have that, but they never came through on their promise, after waiting for a year. We were able to convince management to switch to Zerto.

How was the initial setup?

The initial setup of the product was very complex. We were using a SQL Server cluster with a Nimble array, so it was very complicated to get everything set up correctly so it would failover correctly.

Our deployment took about six months. We had an implementation strategy for the solution but it failed three times before they could get it to work. Our deployment plan was set up to failover for our SQL cluster and several web servers to a backup location. In setting up with the Nimble, Zerto recommended that we use an RDM. The RDM did not work. We were using VMware with Nimble and the Zerto team had not used that particular solution before. We jumped through hoops three times before we were able to get the right combination to get the cluster to failover correctly.

There are only three of us working with Zerto. I am the DBA, we have a system administrator, and we have our IT director. We learned very quickly how to use the product very thoroughly since we had to rebuild our solution three times.

What about the implementation team?

We were working with Zerto directly. They didn't have a good solution and we had to test out a lot of things with the hardware and software that we were using. They could have improved that. They kept giving us solutions that would not work, so we had to keep trying different solutions.

What was our ROI?

It's hard to say if we have seen ROI since it's only been running for about four months. I think that we will see cost savings over the next year.

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

As far as licensing goes, start out with what you need to get started and you can always scale up. Zerto worked very well with us. They have a tool called zPlanner which was able to document how much we needed to get started. That was a very handy tool.

Which other solutions did I evaluate?

We looked at some other options, but nothing really compared to what Zerto offered.

The main differences were the ease of use, not having to have a dedicated person assigned to watching it, and the automation. A lot of this stuff is taken care of through Zerto without us having to script or put a lot of effort in on the back-end. Everything is automated.

What other advice do I have?

Make sure that they can demo what you want done before you move forward. We had a problem with the SQL clustering. Make sure that the equipment that you're using is certified by all the vendors that are involved, like VMware.

Now that we have the solution working, we're very happy. We've had it working for the last four to five months. We were able to test it with a test platform and it worked amazingly.

Which deployment model are you using for this solution?

The replication increases our DR capabilities
Pros and Cons
  • "From a management perspective, one of the biggest benefits is to see the excitement of your engineers having a tool that truly enables them, really making their lives easier. That is something that I love. When we came out of the PoC, their eyes were just wide with excitement of what was possible now."
  • "They could iron out the licensing aspect of it, so we might be a bit quicker when implementing and starting to use it."

What is our primary use case?

We are using it to decommission a data center, then moving the data over to other data centers that will still persist within our environment. Also, we now have a more robust disaster recovery for a lot of our non-vital, non-critical applications.

How has it helped my organization?

From a management perspective, one of the biggest benefits is to see the excitement of your engineers having a tool that truly enables them, really making their lives easier. That is something that I love. When we came out of the PoC, their eyes were just wide with excitement of what was possible now.

What is most valuable?

The replication would be the best feature. It increases our DR capabilities. We put a lot of time and effort into DR overall. For the amount of time that it takes to test and go through those activities on a regular, recurring basis, well, this cuts down on the time commitment, not just by the infrastructure team, but by the application teams and all their peripherals. Even just from a man-hours perspective, it is a huge cost savings. You cut down three hours per application, and an application has anywhere from three to 12 developers plus others who support that application. So, you are probably looking at 20 people times three hours, then times however many applications we have, which is in the thousands. That compounds pretty quickly.

For how long have I used the solution?

We have been officially using it for three weeks.

What do I think about the scalability of the solution?

It seems as though everything on the scalability factor checks out. However, we will see that very soon in our use case.

We have thousands of applications and servers. There is an exorbitant amount of data. 

How are customer service and support?

The support that came in and engaged with us, setting us up through the PoC, were fantastic. Coming out of it, I already have five engineers who have gone through multiple levels of certifications. So, it appears as though that technical expertise, to be able to improve themselves, is right there at their fingertips. It seems highly available. I would rate them as nine out of 10.

How would you rate customer service and support?

Positive

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

We have used Site Reliability Manager (SRM), which is capable, but to a lesser degree. Zerto is 10 times to 100 times easier to use. It is amazingly fast.

How was the initial setup?

I was not involved in the initial setup or deployment.

From the team, the deployment was very straightforward. The proof of concept that we ran took a little over a week. They were able to stand it up from scratch, deploy, and run several tests of varying complexities. Everything went smoothly. We put a contract and agreement together in record timing for our company.

What about the implementation team?

We had a terrific hands-on proof of concept with the Zerto team, where they came in and worked with our infrastructure engineers. Our engineers were completely amazed by the solution's capabilities. As quickly as we could get our licensing in place, we did. Now, we have had our licenses assigned for the last two or three weeks.

What was our ROI?

From our perspective, we are already thin-staffed as it is. So, Zerto has allowed us to focus on other things that are equally important.

We have not been able to apply ROI yet, just because of our circumstances. We are waiting on teams to move out of the data center. However, we are now poised and ready. Once that onslaught of requests come in, that is when we will really see the return on it.

If you are a numbers person, the benefit far outweighs the cost from any other competing software or service provider. When you are talking about trying to keep a reduced amount of engineers in the happiest state possible in their work environment to do the workload that they had traditionally done with double the amount of people on their teams, this tool relieves all the stress that they are carrying with them on a daily basis, even though they don't have to implement it on a daily basis. I have seen that firsthand. That return on investment is almost invaluable.

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

They could iron out the licensing aspect of it, so we might be a bit quicker when implementing and starting to use it. At the same time, our sales rep and all the supporting team members from HPE and Zerto were great and very flexible. It is hard to be critical of that.

Which other solutions did I evaluate?

We have not done another valuation recently. Zerto was the first in quite some time.

What other advice do I have?

I would rate this solution as nine out of 10.

Out-of-the-box test restore documentation helps us meet compliance requirements; and we get true continuous data protection
Pros and Cons
  • "One of the most valuable features, something that I wasn't even anticipating, is the file backups. We weren't even considering Zerto to do restores, but it actually is able to do that. Eventually, we could just use this as our backup solution."
  • "The only issue I've ever had is that I wish that Zerto would work more closely with VMware. There have been a few times that Zerto has released an update but it wasn't supported with that version of VMware. I would like them to coordinate their updates with VMware's updates."

What is our primary use case?

We didn't have any kind of disaster recovery solution in our environment, whatsoever. We're using it for disaster recovery.

How has it helped my organization?

The biggest benefit we get from using Zerto is due to the fact that we have to answer to our gaming authority and prove that we have a DR solution in place. With Zerto we can do it out-of-the-box: do a test restore and actually have documentation that we can provide to our auditors.

Also, before Zerto, we didn't even have a way to fail back or move workloads. Now we do, and we can do so with a few clicks.

What is most valuable?

When it comes to continuous data protection it does the job. With the RTOs and RPOs, it does exactly that. It's the only one that I've seen that you could call a continuous data protection solution.

And one of the most valuable features, something that I wasn't even anticipating, is the file backups. We weren't even considering Zerto to do restores, but it actually is able to do that. Eventually, we could just use this as our backup solution.

It's easy to use. Once I got it installed and going, it was less than a day until I was already confident about using it. I've done numerous upgrades since then without any third-party support.

What needs improvement?

The only issue I've ever had is that I wish that Zerto would work more closely with VMware. There have been a few times that Zerto has released an update but it wasn't supported with that version of VMware. I would like them to coordinate their updates with VMware's updates.

For how long have I used the solution?

I have been using Zerto for going on two years now.

What do I think about the stability of the solution?

It's rock-solid. I haven't had any issues whatsoever.

What do I think about the scalability of the solution?

From what I've seen, because I have four different vCenters coming into it, I'll be able to scale out as much as I can physically handle on the storage side.

We're currently protecting about 100 terabytes with Zerto and we plan to increase our usage of it.

We're not using Zerto for long-term retention right now, but we do have plans to do so once we get some hardware that we can use for that.

How are customer service and support?

Their tech support gets to the point. They've really been on-task and I haven't had to wait for anything. They've provided me with what I was after or answered any questions that I had.

How would you rate customer service and support?

Positive

How was the initial setup?

I did the initial installation, and it was very straightforward. I've never had a solution that is this intensive and yet this easy to deploy. It took a few hours to deploy.

And in terms of working with Zerto on a day-to-day basis, it's just me.

What was our ROI?

We haven't calculated an ROI, but just comparing what it's been able to do for us, versus not having a solution, there has been ROI. It has the potential to help reduce downtime. Fortunately, we haven't had any, but it puts something in place to help us if we were to encounter some downtime. We're a casino, so every hour that we're down we lose hundreds of thousands of dollars.

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

Obviously, I wish it were cheaper and more affordable. But I get what I pay for, so I can't complain.

Which other solutions did I evaluate?

I looked into the VMware solution, but it was just way too complex. It seemed like it would require a longer deployment and fine-tuning well beyond what it took me to deploy Zerto.

The fact that Zerto provides both backup and DR in one platform wasn't very important at the time. I've seen the benefit now and I'm happy that it does, but it really wasn't a factor in what I was looking for.

What other advice do I have?

The only lesson I would pass on is that when we updated VMware, that version of VMware wasn't supported with the version of Zerto we were running. That could be a "gotcha," so make sure the hypervisor is supported under the Zerto matrix.

Request a trial. It's simple enough to install and configure on your own. My advice would be to see, firsthand, how easy it is.

Simple and stable disaster recovery solution with fast failover
Pros and Cons
  • "Stable disaster recovery solution with a very simple setup and fast failover."
  • "The limitation with Zerto is that you're required to have one Zerto Manager per virtual center, and this means that you're only able to replicate one way. Technical support for this product was fantastic, before they were acquired by HP. You're now able to tell that the company is becoming too big, in terms of the support they provide."

What is our primary use case?

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

What is most valuable?

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

What needs improvement?

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

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

For how long have I used the solution?

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

What do I think about the stability of the solution?

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

How are customer service and support?

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

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

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

How was the initial setup?

The setup for Zerto was very simple.

What about the implementation team?

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

What was our ROI?

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

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

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

Which other solutions did I evaluate?

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

What other advice do I have?

We're a Commvault and Zerto customer.

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

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

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

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

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

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

File recovery tool offering reliable recovery of data in the case of ransomware attacks
Pros and Cons
  • "Zerto gives us peace of mind knowing that if we were attacked by ransomware, we would be able to recover data from the time before the ransomware to get us back to being fully functional."
  • "The backup end of this solution could be improved. We tried using it as a full backup solution and it took way too long to complete at least one backup."

What is our primary use case?

We started off using this solution for disaster recovery and DR testing but then it morphed into more of a file recovery tool. We can usually get closer to a point in time recovery using Zerto versus the nightly backups that we do.

How has it helped my organization?

Zerto gives us peace of mind knowing that if we were attacked by ransomware, we would be able to recover data from the time before the ransomware to get us back to being fully functional. Zerto helped to reduce our company's disaster recovery testing model to where we can do it all within a day. We normally pick a time around lunchtime on a set day for the different groups to test with and it is completed by the time lunch is over. 

It definitely does make life easier when you're in a situation where you have to have all hands on deck as it doesn't require you to have as many people to bring everything back up.

What is most valuable?

The file recovery functionality is definitely the most valuable as well as the amount of time it takes to recover a VM. The different snapshots it makes are great, especially when we try to schedule DR testing with our business unit. The less time that we have to spin up the environment, the better the whole testing process will go.

One common use case I'll get is when someone says, "I deleted," or, "I've changed a file." I can ask them, "What time did you do it?" If they tell me a specific time, for example, 1:15 PM, I can pull that file at 1:14 PM and recover the data.

What needs improvement?

The backup end of this solution could be improved. We tried using it as a full backup solution and it took way too long to complete at least one backup. We tried it once and didn't try again. I'm not sure if they've improved that since then but we actually went in a different direction for backups.

For how long have I used the solution?

I have been using this solution for six 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?

We haven't had to scale much as we're a small business. If we were to grow, it would be a couple of servers at a time so I can't really speak to the scalability of it. We have 400 servers total and only use Zerto with what we consider mission critical.

How are customer service and support?

The customer support is excellent. When you call with an issue, they answer almost immediately. The guys are really knowledgeable.

I would rate their support 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 started off with Site Recovery Manager. We did not like the process and once we tried Zerto, we saw how easy it was. That's been the solution until recently as we've added a second data center in which we use now Pure Storage with VMware. They do active clustering and we can use a simple vMotion to move from one site to another versus the way we used to do it before completing a migration with Zerto. 

We still keep using Zerto because we know Zerto works. Zerto is a lot faster especially compared to what we used to do with Site Recovery Manager.

How was the initial setup?

The initial setup is straightforward. I just followed the documentation online and it was set up in a day.

What about the implementation team?

I completed the setup myself. There may have been a help check afterwards once we got the first test recovery group setup. 

What was our ROI?

Based on the fact that we can rely on Zerto for recovery if anything were to happen and the confidence that our management has in this product, it's definitely worth the money. 

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

We paid a big investment upfront with renewal fees each year. This is another reason why it's easier for us to keep this product as well as have another solution, because we've already paid the money upfront.

What other advice do I have?

When evaluating Zerto, I would advise others to try to think of any potential scenario to test with and use it to prove whether it does or doesn't work.

I would rate this solution a ten out of ten.
