HPE Zerto Software Reviews

We do a semiannual disaster recovery test, usually one in January and another in September, where we fail our entire company over to our Arizona DR facility. We run the business out of the Arizona location for the day. In order to be able to do that, the Zerto application allows us to migrate 58 machines over to that location and allows us to run our business from that location for the course of the day.

We are able to have a successful disaster recovery solution through using Zerto for our Disaster Recovery drills. We are able to fail over anytime, day or night, to run our applications out of our Arizona facility. Within a 15 or 20 minute time frame, we can have those application servers up and running in Arizona. It is just a huge help to have a successful, reliable disaster recovery solution that we know at any point in time, within 15 or 20 minutes, can be running out of a different location.

Most of the time, this is at least a two person job. Previously, when we had a disaster recovery drill it would take two of us working for three or four hours just getting applications up and running in Arizona. Now, for the disaster recovery drill, I'm able to finish my work in about 30 mins and be available onsite to help and assist anybody else as needed during the disaster recovery drill. Its ease of use and the ability to have a reliable solution for disaster recovery has become invaluable to us.

There is built-in active logging if needed for a longer retention period. If we fail a machine over and are just doing tests for it, we can fail it right back at the end of the failover without much issue. We couldn't do that with SRM. The ability to keep track within the activity log of what is going on with the VM, then fail it back prior to the one-hour time frame that we have set up without having to worry about it losing data during our tests or production failover drills.

The product is very easy to use. On a scale of one to 10, I'd say it's a nine as far as ease of use goes. In order to do an update in our old product (SRM), we basically had to take down almost our entire vCenter to be able to do the updates. Whereas, I can do updates to our Zerto product within 30 minutes to both our ZVMs in Massachusetts and Arizona. We haven't had problems troubleshooting after doing upgrades. Within five minutes, we can configure a whole new cluster solution and work on getting it synced out to Arizona.

It transfers up-to-the-minute files. Therefore, if something was to happen and the business was to go down Massachusetts due to a server failure, we could simply fire up those VMs in Arizona within approximately five minutes. The data protection level is top-notch. We haven't lost any machines, data, or VMs during the course of utilizing this product.

The alerting doesn't quite give you the information about what exactly is going on when an issue comes up. We do get alerts inside of our vCenter, but it doesn't give you accurate information on the error message to be able to tell us what's going on without having to go actually login into Zerto to determine what's causing the issue.

Another issue with the alerting is that it will pause a job. E.g., if we have something running from Massachusetts to Arizona, but a VM has been removed, updated or moved to a new location in vCenter. It literally pauses the VPG the VM resides in but will never give us a notification that it's been paused. Therefore, if we had an issue during the course of the day such as a power event and we needed to gain access to those VMs in some sort of catastrophe, we wouldn't be able to get access to them because that job was paused and were never notified about it being paused for whatever reason. It would therefore be a big problem if the VM was needed to be recovered and we didn't have those resources available.

It would be great to get more precise alerting to be able to allow us to troubleshoot a bit better. Or have the application at least give us a heads up, "A VPG job has been paused." Right now, it's sort of a manual process that we have to monitor ourselves, which is not a great way to do things if you have a superior disaster recovery solution.

Almost two years.

The stability is rock-solid. Nothing has gone down since we installed it; there has been no downtime.

Typically, once a quarter, we have an update. Last year we were at version 7.5, then we recently went updates to 8.0. On top of that, they release security patches and other things to improve bugs they find in the program. Right now, there is a U4 version that's out, which we will be updating to this quarter.

In the U4 version, there are security enhancements because a lot of zero-day issues that are being found in a lot of the applications. Zerto is making more security modifications and enhancements to the encryption between one location and another, so somebody can't hack your data and access it while it's in transition.

Scalability is very easy. We are going through a POC right now because we want to branch out to the cloud. Just getting that set up and going through the process was about 60 minutes.

It's very scalable and extendable. We can do one to many solutions, as far as where our disaster recovery is going. This is what we wanted. We would never have been able to do that with our SRM product.

There are two engineers trained to use the product. I'm the primary contact for the application and do most of the work on the product. One of the storage guys handles a lot of the storage set up on the back-end with me. We have at least two people trained on each application that we have in-house. Both of us are in charge of making sure the application is up-to-date and doing what it's supposed to be doing. 

Zerto's technical support is very good. They are very reliable and always very pleasant to deal with. We've never an issue working with them. They usually come back with the precise solution to whatever we are troubleshooting.

Our issues are usually user self-inflicted. E.g., we remove a host out of the cluster to upgrade it or do something else with it and don't follow the correct procedure that's needed in order to be able to shut down the Zerto appliance correctly. If somebody doesn't follow that procedure, because they either don't know how, weren't aware of it, or just skip that step, then it causes problems inside of Zerto. This will pause jobs and the VPG will no longer be accessible on that host. Sometimes it's easy to get it back up and running again. Usually, when you put a new piece of hardware in the cluster that has a different set of parameters with its hardware, then the appliance will be missing because it was taken out with the old hardware. Usually, you need to get their technical support involved in order to be able to troubleshoot the issue with them to be able to get the VPG back online again on the new hardware. As I said its self-inflicted most of the time because steps are missed with our processes.

The documentation that we got from them was in depth and work well when needed, if you follow them correctly you will have success. If you don't follow the steps, that's when problems develop. Therefore, it's not a fault in their documentation, it's a fault of the user who's not following the proper steps for success. It doesn't happen often but I think we have contacted technical support only three times in the two years that we've had the product.

For eight years prior to using Zerto we used to use a product called SRM, which is part of VMware. We finally switched over to Zerto after having them come in and do a presentation for us. This was after trying for about a year to do that and convince our vice president to allow us to migrate over to a different platform.

The reason why we used SRM was because SRM was built into our VMware vCenter licensing. We never had a successful DR test during the previous couple of years with SRM. By switching over to the Zerto product a year and a half ago, we were able to run a successful disaster recovery test within three months of switching over. We had our first successful disaster recovery tests in two and a half years because Zerto made our life so much easier and helped getting servers over to a new location almost seamlessly. 

In order to be able to have a successful disaster recovery, we need to be able to successfully migrate 58 servers from our Massachusetts location to Arizona. On previous attempts, we got about half the stuff over there, then we'd fail. In other scenarios we would get everything over there but some of the machines wouldn't come up because of the way they were configured. One time, the business was down for about half the morning because it took us that long to get the stuff back up and running using SRM. This was a real pain point for us, getting this product in place and working successfully. It took Zerto to be able to finally get us to do that. It's been a lifesaver. All we had with SRM was nothing but headaches.

The initial setup was very straightforward. We had everything running in half an hour. It got deployed with two virtual machines (ZVMs): One got deployed in Massachusetts and another in our Arizona location. From there, we deploy appliances to each one of the hosts that's inside of the clusters that we are managing for our disaster recovery solution.

Within 30 minutes, we had it deployed to our entire production cluster and the hosts in here. After that, we just started creating jobs, which took quite awhile to do because we have a lot of large servers. However, that's not the worry of the Zerto application, but the size of the VMs we have in production. 

For our implementation strategy, we just mimicked what we had in place for our SRM environment. Our 58 machines are spread across different clusters: some in our DMZ, some in our prod and some in our WebSphere clusters. After that, we ran two tests to ensure that we were able to fail over to our Arizona location then fail back without any changes or modifications to the VMs. Once we did that, we started rolling out to each of the clusters, one Virtual Protection Group (VPG) at a time. I think we now have 23 VPGs total.

We worked with an outside vendor (Daymark) who does a lot of our work through outside vendors. They work with Zerto directly. When we set it up originally, we had a Zerto technician on the call as well as a Daymark technician on-site working with us.

Our experience with Daymark has been very good. We love working with them and try to use them for our integration and infrastructure work. They are a very good company that are easy to deal with. We try to use them as much as we can. Thanks to Rick and Matt for a great working relationship.

We have seen huge ROI.

It used to be a three-person job, and now it only takes one person to manage and run the process. The fall back is the same thing. We've never had any issues with stuff coming back out of Arizona to our Massachusetts location. Within 15 to 20 minutes, we can have our servers successfully migrated back, then up and running just as they were originally without having too many conflicts or configuration issues. 

The solution has helped us reduce downtime in any situation that we have come across, thus far, for disaster recovery at a 4:1 ratio.

We are an insurance company therefore, if we're down for an hour, it's thousands of dollars being lost. E.g., people can't pay their insurance bills, open new policies or get the support they need for an accident.

These things have been invaluable to us:

• Not having to have so many bodies onsite during a disaster recovery drill.
• Not having to worry about multiple people dealing with the application.
• The product's reliability of always being up and running and not having any issues with it.
  

It's very equitable, otherwise we wouldn't do it. It's something that we utilize for the licenses per host used. Therefore, it's very cost-efficient as far as the licensing goes. For the amount of stuff that we have configured and what we're utilizing it for, the licensing is not very expensive at all.

There is a one-time cost for maintenance and support. We have a three-year contract that we will have to renew when those three years come up. There is also licensing on top of that for whatever product you are using it depending on the host configurations.

Right now, we use Veritas. We will be evaluating Veeam and Rubrik as a new solution for our backups in the next quarter or so, on top of the fact that we may decide to use Zerto. The three of them are in the mix right now for when we decide to switch over vendors for a better backup solution. 

Zerto gives you the ability to utilize it as a backup solution, but it's not a true backup solution because it can't do file level backups. If you want a particular file off of a server, it can't do that for you. What it can do is give you the whole server, then you need to go back and pull that file off it. Mainly for that reason, we haven't chosen to use Zerto and may never use Zerto as our backup solution. The other solutions allow us to get a file level backup.

Don't hesitate. Go out and do it now. Don't wait two years like we did. Push harder in order to be able to get the solution in place, especially since we know it will work better for you. Don't just take, "No," for an answer from senior management.

The application is phenomenal. They continually add new things, more plugins, and modifications to the way things work. It just gets better as they go.

We don't plan to use the solution for long-term retention at this time, but we are looking at going into a hybrid cloud solution in the near future which we may be using long-term retention for to make a duplicate copy of everything we have in our Massachusetts data center into a cloud solution. Whether it be an Azure or Amazon location on the cloud.

While I can't really speak to whether it would allow us to do it, the application is set up to create a duplicate of the actual servers in Arizona. That's how it works so quickly. If we ever had a problem, I could always revert back from the duplicates that we have out in Arizona using the application, if necessary. Luckily, we haven't had a need for that, and hopefully never do.

I would rate this solution as a nine (out of 10).

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

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

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

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

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

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

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

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

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

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

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

I've been using Zerto for about a year.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

We use it mainly to move the server alarm between vCenter and the physical center.

I like that Zerto is easy to move and that there is no effect on the user. That is, the user doesn't even know it. We're in the healthcare industry and work for a hospital. We can set up a server in no time whatsoever. It's easy for us to schedule the time because it takes only about one minute.

In terms of ease of use, Zerto is a lot easier to use in comparison to similar solutions.

We have had no downtime with Zerto.

The speed of our upgrade is a lot easier because, for example, when I put the move fail and there's a pullout from the destination, I can cover with something from the source and pick it up from the source in person. I can copy the tag from the server very fast.

Customer service and technical support need improvement.

I've been using it for about five years.

Customer service and technical support need improvement, and I would rate technical support a seven out of ten.

Neutral

We switched to Zerto because it is easier to use, and the users did not complain.

The initial setup was straightforward. You open the firewall, install it, connect to vCenter, and then do all the steps to install the software.

On a scale from one to ten, I would rate Zerto a seven because of the bad experience I had with technical support.

We use this solution for replication from our primary data center to the secondary data center.

The replication feature and DR functionality are most valuable. Zerto has many options when a new server is provisioned. If the application team would like to use a replication process, DR process, or RPO, Zerto can facilitate this within 15 to 20 minutes.

This solution could be improved by including some sort of compression or de-duplication for the same type of files.

We have been using this solution for three years.

It can be scalable depending on the licenses which can be quite expensive. 

We previously used SRM. SRM is as not as good at Zerto. That's the reason we bought the licensed product as opposed to the free product. I'm hoping that Zerto will be used in the future in our company for data replication purposes like SQL data.

The initial setup was very easy. I followed the documentation to set it up myself. The person completing the setup needs to understand the storage layer and the network layer for the backup. Without this understanding, It may be extremely confusing.

When you apply Zerto to your environment, you need to understand your networking settings, storage settings, and your capacity planning. Setting up Zerto took us 15 minutes. 

We recently bought more licenses and are exploiting the benefits of Zerto so I would say we are seeing a return on investment. 

Zerto helped to reduce downtime drastically by 80%. I would advise others to complete a full evaluation process to ensure they get the most out of it.

I would rate this solution an eight out of ten.

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.

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.

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.

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.

I have been using this solution for six years.

This is a stable 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.

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. 

Positive

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.

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

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

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. 

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.

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.

We are mainly using it for DR and, in a few use cases, we leverage it for migration as well. It really fits our use cases.

The experience has been smooth when it comes to DR testing, as it has reduced the testing we need to do. 

Some of the most valuable features are the synchronous replication and migration with RDMs. I really like the conversion of RDM VMs for migration. It is very simple to use and fast. We haven't run into any issues.

If we have multiple VMs in a VPG (Virtual Protected Group) and one VM is hung for DR, it holds things up. The only alternative is to create multiple VPGs. It would be nice to have one VPG where, if one VM is failing, it does not impact the overall process.

We have been using Zerto for close to a year.

Our experience with Zerto has been good, but I don't know if we have actually saved a ton of time with it. There have been no issues or real challenges so far. We just recently adopted and started using it, so in terms of implementation of real use cases, it has barely been a couple of months. We haven't even done a single upgrade of it yet.

The stability is good.

We right-sized initially and we have not had to scale up yet.

I haven't had to engage support. One of my colleagues handles that. But I have heard no complaints about support.

We have a VMware product, SRM, and we use it in a few data centers around the globe. We started using Zerto in a few locations and, in other locations, we still have other products being used.

We were using SRM in our data centers and what happened was that we had a merger. In that process, the other party already owned some Zerto licenses. That's when we got our hands on it and started looking at it. We figured Zerto would be a better fit for our European data centers. We ended up using Zerto there and then got more licenses so that we could use Zerto more.

We have one other solution that we use for live migrations, VMware HCX, rather than Zerto. But we were not always able to use that. That's where the delta for those VMs is, and why we use Zerto for migrations.

The speed of recovery of Zerto is right up there compared with other solutions. It's good, no complaints in that respect.

Compared to other solutions, Zerto is very straightforward and simple to use. The preparation for DR is fairly straightforward, and the deployment is not very complicated.

Zerto hasn't cut the number of staff involved in data recovery, for us. We had one engineer doing it before and he continues to do it. He wears multiple hats. You cannot go down to less than one engineer.

We use it for backup and replication.

The total time for replication has been reduced drastically for us and that really adds value in the long run because time equals money and resources.

It has also helped to reduce our DR testing. Previously, when we were doing it across our own locations, we had to make sure it was working by doing a lot of testing back and forth.

Also, the solution is already up to the mark on audits and certification.

For us, the most valuable features are the quick upload time and how the sync works. The sync is pretty good and that's really helpful. The quick upload is important to us because other solutions were lagging behind. We have VMware SRM and Veeam, and they have been pretty slow and sluggish. We have had some challenges with them.

We have been using Zerto for seven years.

We're just replicating and I assume it runs on some kind of cloud as an overlay, so the stability is pretty good.

The scalability is insane. Really good.

An area for improvement is the support because it gets really expensive. They need to make it a little cheaper. Support also takes time.

Neutral

We still have some other solutions in-house. We are not fully dependent on Zerto. We are still trying to get rid of the others, but we have not entirely moved on.

In 2014, when Zerto was launched, the initial setup was pretty simple.

We used an integrator. Our experience with them, at our engineering level, was that it was pretty smooth and streamlined, the first time we used Zerto. We had a few issues in the initial deployment, but later on, when we moved to scripting, the process became streamlined.

I would like to see different service levels. They're good, but it still takes a lot of our budget in ops.

We evaluated Veeam and SRM. Zerto is an HPE product, and we have been using a lot of HPE servers. That trust in HPE won our business.

When comparing Zerto with Veeam and SRM, the latter are newer in the market. They try to provide a multi-cloud strategy with tie-ups across six different clouds, which is different from Zerto. That's where I would use them if I had to.

All the solutions were almost equal but Zerto is still better because they have a lot of releases and new versions.

We are just using it for backup and replication. We have not yet had an event where we have had to restore.

We primarily use the solution for continuous data protection and cloud onboarding.

The analytic tools are great. 

The external API is something we're using quite a lot. It was upgraded, however, we still haven't upgraded to nine. We were starting to work at six, then seven, then eight, and now we are at eight of five updates. We've been working with this product quite a lot, and they have constantly added a few features. The long-term journal is one feature that is useful in that it allows us to use the product as both CDP and backup. You don't need the backup and disaster recovery tool. That's lowered the overall maintenance and operational costs. The OPEX gets reduced, once you use these two products. 

They have reasonable support. The Zerto university for training staff is very useful. It's very easy to get people on board and to get technicians to work and be familiar with the product. The virtual labs are very useful. You have a sandbox and you can easily play and try the product.

Unlike other products that split the VPG into protection plans and activation plans, they're doing everything within the same location. 

Technical support is good.

It's a very stable solution.

They could improve their online documentation.

From a reliability perspective, the product is around seven. It's less reliable than, others for example. They have one limitation when they have a virtual protection group that does everything.

From the ease of deployment perspective, it requires expertise and time. It's not very easy to do auto-tagging or to run multiple VPG genes at the same time. So, from multi-tenant or multi-complex scenarios such as using Zerto external products, such as firewalls, while their own product is good, it's part of a larger ecosystem, that still has a long way to go.

The triggering of external products could be better. Combining a master runbook and not just a single VPG or splitting the protection group from the activation plan could be better. There will be a protection policy and activation policy as being done in other products. 

Better tagging and better multi-term support are needed. Currently, there is no tenant admin support, only global admin support. They should work at the tenant level instead of the global admin level.

Right now it's an HPE product; they're no longer a startup. We are hoping that being bought by a major company will do good for them and they'll fix what needs to be fixed. There were very good products, to begin with, and HPE should work to make it even better.

We've been using the solution for the last three years at this point. 

The stability of the product is good. There are no bugs or glitches. It doesn't crash or freeze. it's reliable and the performance is good.

Technical support has been great. We are happy with the level of support.

We use both on-premises and cloud deployments. In terms of the cloud we are using, we are using Azure. We are using our own Cloud provider; we are using VMware Cloud Director.

I would rate the solution at an eight out of ten. We are happy with its capabilities. They are a very good product, however, they are not perfect just yet.
