HPE Zerto Software Reviews

We use Zerto for offsite replication.

I like how easy it is to run our DR tests with it.

In terms of ease of use, in the user interface it's very easy to tell the different virtual protection groups apart. It's easy to figure out where your virtual machines are and set different recovery IPs. It is a lot easier with Zerto than it was previously.

When you compare Zerto's ease of use versus that of the previous solution we used, Zerto has good documentation. That's probably what made it the easiest to install and configure, and have peace of mind that it's going to do what I expect it to do.

Every six months when I go through my audit, I don't have any stress about whether I'm going to pass any of my audit logs or any of the questions the auditors ask me. That is, I know I'm going to pass.

Zerto helped us reduce downtime.

Our disaster recovery test used to take quite a long time before we started to use Zerto. After we started using Zerto, the speed of the virtual machines' backup when they are going into test mode, is just so much quicker and so much more consistent. When we previously performed tests, we would need a block of about a week. Now, it's two days. The actual recovery portion is just a small part of that, but Zerto cut it in half easily.

I've been working with Zerto since 2019.

The stability is great; there's very little downtime. I don't have to worry that there will be a surprise update to one of the ZVRAs or the host that I have to contend with. We're given plenty of notice to plan ahead for an update. As far as losing service and downtime, we haven't had that happen.

We're a very small shop, but when we did expand to another group of servers that we were going to replicate, it was very easy to go in and just add another virtual protection group, add my virtual machines to it, and set my settings up and go.

We have less than a hundred virtual machines that we replicate.

The technical support staff I've had to interact with have certainly been some of the better ones. I feel that their turnaround time is always pretty fast and that you get reasonable support right off the bat. If my problem is a little more technical, then I may be transferred, but I don't find that to be an issue. I would rate technical support at nine on a scale from one to ten.

Positive

The initial setup was pretty straightforward for the site-to-site recovery or for setting up the VPGs. If you just want to do basic replication and you don't have a lot of special situations to account for, you could have it up and running very quickly.

For special situations, there are options within advanced settings. You don't have to dig too far for them, but they're not quite as straightforward.

We implemented it ourselves after reading through Zerto's best practices, etc.

If you want something that you can set and forget, Zerto is a solution you should look into. If I were to rate Zerto on a scale from one to ten, I'd give it a nine.

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.

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

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

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.

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.

I have been using Zerto for about a year.

It's very stable.

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.

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.

Positive

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.

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.

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.

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.

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.

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.

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.

We use Zerto as a migration platform from a customer's data center or from their on-premises environment to our data centers. We also use it for disaster recovery.

Zerto has helped to reduce the number of people involved during a data recovery situation in our company. All we have to do is click a few times. We have even configured a DR solution for our customers so that they can do it themselves. We give them access to the Zerto platform, as well as have a small manual of instructions, and they can go do it. It's very simple to use and to deploy and to support. It does not have a very large learning curve.

For our clients who do DR in the cloud, Zerto has definitely saved them money. We only have a few DR client accounts, but for the ones we do have, there haven't been any failures of Zerto, whenever we do failover tests. It performs well.

It's a great platform because it's very well built, technically. 

It's also very much faster than any other migration or disaster recovery platform we have. I work with virtualization, mostly on VMware, and I must admit that Zerto is even better than VMware Site Recovery Manager. Zerto compresses the data and it works much faster. We use it whenever we can, and especially whenever we are on a tight time schedule for closing a project, or we need to bring information or VMs from a client or from another data center. Zerto is very valuable because of its speed.

And in terms of ease of use, when I started with my current company I didn't even know about Zerto. My first project was a migration from a big customer and I thought, "Wow, this will be a lot of work." It was a little scary because of the pressure to get it done. But Zerto was so easy to use. I like it a lot.

I've been using Zerto for about 12 months, but the company I work for has been using it for four or five years.

It's very solid, like a rock. It's very stable.

Even with the most recent customer that we migrated to our data center, it was really impressive that Zerto kept the levels of performance very consistent. This customer's site was at another data center provider, not one of ours. It was on a very old VMware version, and we were deploying them to the latest, vCenter Server 7. At first I thought, "We will be struggling to bring this customer over," because they were two major versions behind. I didn't think Zerto would be compatible for making this migration happen. But it worked like a charm, and we had no problems regarding Zerto itself. While we had some problems with this migration, they were not related to the technology.

It's very scalable. Most of our core usage here is for migrations from our customers' on-premises or data center instances. And about two years ago, we had a very big migration of over 3,000 virtual machines, and Zerto performed really well. That's why we have kept Zerto in our portfolio.

Their support is amazing. We have had to open some support cases and they have a very good technical team. They're always referring us to their technical teams if we need to discuss something. Or if we fail to understand some of the concepts, we can reach out to them too. It's more than a commercial relationship. They support us whenever we need help.

Positive

We do setups of Zerto every week or two weeks, because it's not a single platform. We are a multi-cloud environment and service provider. We deploy it according to project requirements. So we don't have a single Zerto platform. We are always deploying VMs and DRs.

Zerto is very easy and straightforward to set up. Whenever we want to use Zerto for a migration from an on-premises customer to our data center, we usually create a WAN to WAN link, or a LAN to LAN, or a VPN link between the customer and us. We just deploy the VPNs from our side to the customer site and request access to their environment. We check for special VM configurations. It's pretty straightforward. We don't like telling the customer to do it, even though it's very easy to deploy and configure, because it's part of our service to do this job for them. We also have our own guidelines and policies that we use to configure Zerto for the best migration setup.

The last deployment I did took me four hours, which included setting up both my side and the customer side, doing the pairing and, later, the VPG's. We migrated over 100 VMs and it took about two days to fully replicate their site to ours. The migration window to do the move was about six hours because they had to change applications. But the move itself took no more than two minutes for every Zerto machine. 

When I talk to the customers, I tell them that it will be faster than the move window we request. Most of the time set aside for the window is for taking applications offline, because they will often need to reconfigure them. When client data comes from an on-premises site to our data centers, there are usually IP address changes, or we have to update VMware tools, or do something at the Zerto machine level by changing Zerto hardware, such as a network card. The moving itself is pretty straightforward.

Because I'm a support engineer, I don't really work directly on the commercial side of things. Whenever I need to request a license for Zerto, someone on our dedicated licensing support team takes care of it. So I don't know if that process is easy or not.

Zerto works very well as a backup and recovery solution, with frequent recovery points. It's very good. But it's too pricey for us to use it as a backup solution for all of our clients. Not every customer needs recovery points every five seconds.

It's a great platform, if you use it as a recovery system and as a migration tool. It's really amazing. It's a very well-developed product and one of the best solutions. In the same way that what makes Microsoft big today is Active Directory, which is an amazing product and one that no other enterprise could do any better, Zerto is the same type of leader in its category and is at the very top, without a doubt.

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

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.

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.

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.

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

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

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.

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.

Positive

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.

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.

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

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.

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.

Our primary use case is for our Tier 1 application environment, we're an SQL environment. We have around 25 VMs that are replicated to a hot site or warm site. And we're a VMware shop and we use Pure Storage as our SAN, but that doesn't matter because Zerto's agnostic. 

We're a small shop. I am the only Zerto user and my official title is Senior Systems Engineer. I handle anything data center-related as far as information stack, the blades, networking, VMware Hypervisor, and Pure Storage. We also have a Citrix environment as well we have to support. I do all of the data center work.

Zerto is a set it and forget it kind of thing. At least it's more of an insurance policy for us. We don't have a good DR plan, but the peace of mind knowing that the data is replicated off-site, like a repository or offsite environment, there is value to that. We just haven't been able to fully embrace the actual testing of the failover and failback process. The testing has worked, but we haven't done a full production failover yet. We've been planning for around a year to do one but it keeps getting pushed back.

Being hardware agnostic is nice in that we don't really need a 15 second recovery time. It's easy to use. It's always doing updates behind the scenes. These are the positive things. The setup is pretty easy. Building out the VPGs is pretty easy. And it works like it's supposed to.

Zerto does what it says it will do when it comes to providing continuous data protection. It gives me all my recovery points up to 15 seconds or less. So if need be, we could recover to that point in time that it says it can do.

Zerto is easy to use for the most part. It's pretty simplistic. The UI is pretty simplistic. There are some things that I'm waiting for newer releases to address some functionality that I'm curious to see has been fixed or not in the new version.

There are still some pieces in testing that aren't automated. There are still some built-in scripts or workflows I wish Zerto would do out-of-the-box, versus having to PowerShell or have a vendor create it, or create it myself. We haven't done a full failback yet of production so I couldn't really say. The failover process is a lot of manual steps, but Zerto is a mechanism that gets the data there. In that aspect, it does what it's supposed to do. But I wish they would expand on their out-of-the-box functionality for the VM. When you fail it over, there are DNS and SQL changes and there are reboots. There are some things I wish that Zerto would facilitate with a checkbox that would do some of these things for me versus having to PowerShell it and put the scripts in a certain place and have support run it. I want it more automated if possible.

The issue I have with ransomware is if I don't know I have ransomware in all my recovery points, and if it goes three months, I wish Zerto somehow either bought a company or could tell me that we're infected with ransomware. If I don't know how ransomware and everything gets encrypted, there's nothing to restore back to if all my recovery points have been corrupted. So I wish Zerto somehow had a mechanism to alert me of suspicious activity.

We have a Trend product that does that for us. We can get alerts of things that Trend finds, but it's always nice to have layers for your security. We have alternatives, but it would be nice if Zerto had a mechanism to alert me as well.

Alerting has also been a pain but it was supposed to be fixed in the newer version and that's. I would like to have more granular alerts.

I have been using Zerto for about four years now. 

When it comes to stability, it does what it says it's going to do. 

I do some babysitting because the alerts are relentless. My biggest pain point is the endless amount of alerts that are just noise. I have to log in and see what actually is an issue because the alerts are just endless. There's not much maintenance I have to do besides logging in and babysitting from time to time.

We keep wanting to test it. It's our main DR strategy, but we just haven't had a window to vet full failover and failback. As far as increasing, I think we're pretty stagnant at the point with what we're backing up with it.

I would rate Zerto support a seven out of ten. 

The initial setup was straightforward. You could deploy the VRAs pretty simplistically as long as you set an IP via the UI, so that was pretty easy. We were up and running in a day.

Our implementation strategy was rushed. We were doing a data center move and we just wanted an extra copy of the data. So this was a stop-gap solution that we stuck with.

We used a reseller for the deployment. They met our expectations. They provide the product, but outside the product, we have to get a stronger resource. If it goes above and beyond like if it's broken, they call Zerto support. If I want some PowerShell scripts and some cool stuff to be done, they need to find a resource. They provide the basic service, which is great. Above and beyond that, they're average or below average.

We pay monthly for the CPU, memory, disk space, the Zerto replication, and then there's a Microsoft charge as well on top of that for the operating system. We pay month to month and we go year to year.

There are additional VM resource costs.

My advice would be to think about the large VMs that you're backing up. Think about the wasted disk space and wasted resources on your production environment, and if you replicate that to a hot or warm site, you have to pay for those resources. The Zerto price is what it is, so you need to work with the business and ensure your Tier 1 or most critical VMs are what you're backing up or want to back up, not just everything. Then scale that to something manageable for replication and find out if you can have minimum resources while replicating and then scale up in a true DR scenario and only pay for the resources as you need them.

It's not really Zerto's fault, but you don't have full visibility on the protected site so you have to rely on your vendor for visibility if an issue arises.

I would advise asking a lot of questions. If you're an SQL environment, make sure you failover all the key components in the correct way. If you want it fully automated, make sure you buy some extra hours to get professional support.

I would rate Zerto an eight out of ten.
