Zerto Reviews

I am a system engineer and IT architect. We use Zerto to protect our production -environment and critical applications. Everything is on-prem. We don't do any DR to the cloud. We're protecting around 300 VMs right now.

I've been fortunate enough not to need to rely on Zerto in an actual disaster, but we do testing every year. Sometimes, it's multiple times annually or at the year's end. It takes the recovery workflow, which would normally take a lot of planning, and reduces that to just a few minutes. 

The most valuable feature is the low RTO that covers our VMs and a secondary data center.

I would like Zerto to add support for VMware's lifecycle manager. 

I have used Zerto for about eight years.

I rate Zerto eight out of 10 for scalability. We have one instance per data center that supports everything that we need, and we haven't had to scale past that.

It's been several years since we've looked at other products. We used VMware SRM in the past, but Zerto is way faster. Zerto is easier to use than other solutions we've tried. 

Zerto is easy to set up. Once you've deployed the appliance and connected it to a  vCenter, your VMs are protected pretty quickly.

Zerto costs us several hundred thousand dollars a year, and we haven't needed to use it in a real DR situation, so it's hard to quantify an ROI. However, based on what we know from testing, it will be a huge benefit in the worst-case scenario. 

Zerto's pricing is pretty competitive. They recently went through a licensing change where you have to buy an enterprise license as an organization. We weren't happy with that just because it forced us to pay for extra features we don't use. We would prefer if we could still have that standard license.

I rate Zerto nine out of 10.

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

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

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

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

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

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

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

Setting it up is very easy. 

Everything is automated using scripts. 

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

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

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

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

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

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

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

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

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

Positive

We previously used SRM before Zerto. 

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

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

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

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

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

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

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

We primarily use the solution for disaster recovery. 

We set up the environment and we're testing right now. We are able to do test recoveries and restalls. Once we have everything set up, we'll try a real failover test. 

The DR - Disaster Recovery - is the main selling point. We have a policy that requires us to have, in case our primary goes down, a failover for our production environment to another site. 

The near-synchronous replication is very good. You can set it to a second. It's important to our company. All of our applications are a part of our production. We need to have uptime. We have an SLA that meets uptime requirements and needs to stay up to maintain our company reputation.

We are also protecting our VMs. 

It's had a positive effect on our RPOs. It's meeting our objectives.

The journal history is only up to 30 days. If it were longer, it would be better and I would have more flexibility.

I've been using the solution for a little over a year. 

The stability is great. It is running well. 

The scalability is not too bad. We upgraded our server and we were able to scale easily. We installed Zerto on our VMware with no problem. We have about 200 VMs and Zerto is protecting about just under 100 of them. 

Technical support is an area I'm not too keen about. My experience is 50/50. Level one support doesn't seem very knowledgeable and I don't get the answers I want. That can delay us sometimes. Hopefully, they will improve. 

Neutral

I was involved in the initial deployment. 

The process is not too bad. The process was pretty straightforward. 

The vendor provided implementation support. 

We have noted an ROI. Compared to others, overall, it made sense to choose Zerto.

They are not cheap. They are more expensive than others. However, they have great features.

We did test other solutions. The speed of recovery in comparison testing was great. That was the reason why we chose Zerto over our competitors. 

We looked at Veeam Orchestrator and Veeam is not as complete in terms of DR. 

The ease of use of Zerto and the interface are easier to understand and use.

I'm not sure which version of the solution we're using. It's around version eight. 

I'd rate the solution eight out of ten overall. 

We use it for failing over our production servers in the event of an emergency so that we have minimal downtime to continue business operations.

We only use it for failover to on-prem. We do not use it for the cloud.

Zerto was one of the first failover solutions that we implemented in the organization, so the benefits are pretty drastic. It is hard to compare it to any other solution out there because we do not have anything to baseline it on, but it certainly increases the confidence of our end users. We are able to react in the event there is an issue. The fact that we are not waiting for hours to restore operations is something that we find valuable.

We protect VMs in our environment with Zerto. We are very happy with the RPO results.

Its ease of use is most valuable. The online documentation is very clear and helpful. We are able to solve a lot of problems on our own without having to contact support.

We learned that we got a new account representative supporting our account. I found this out today. Apparently, this is something that they kicked off at the beginning of this year, but there has been a failure in communication in letting us know who is the proper channel for us to reach out to if we need assistance. 

While going from the major version 9 to 10, they introduced a new requirement for ECE Licensing, which is not something that we knew about at the time of our last renewal. We purchased it for a couple of years, and as far as we knew, we were in support. It was only when we were in the middle of the upgrade and had set up the entire environment and tried to put it up, it asked for a license key that we did not have. We were told by the support team to reach out to our account manager. She has been a bit slow to respond. It just seemed like lip service. The timing kind of worked out because there was a conference as early as that. They have been trying to fix it and communicating about it. I am hopeful it will be resolved, but I just cannot say for sure how soon or how fast they can remediate it.

I have been using Zerto for about two years.

It is stable.

We have not had any issues increasing the number of VMs being protected as long as we have licenses. We have over 100 VMs.

They are responsive, but when things need to be escalated, it is very unclear who is going to be the person to ensure that things are resolved. I would rate them a six out of ten.

Neutral

I was not involved in its deployment.

It is hard to say, but the value is there. At the end of the day, the benefits of having a failover solution outweigh the cost.

I did not participate in the evaluation of other similar solutions.

Overall, I would rate Zerto an eight out of ten. We are interested in the technical abilities that it offers, but we would like to see an improvement on the support side.

We use Zerto to help our customers migrate and consolidate data centers, especially crossing different geo spaces or long distances.

I haven't used it for downtime, but our customers have it configured for all of their disaster recovery needs.

We work a lot with customers that need disaster recovery and the best possible migration approaches, and Zerto helps them minimize the amount of effort it takes to finish their upgrades or migrations.

Zerto helped reduce our customer's VR testing. It allows them to do disaster recovery tests a lot better and a lot safer without affecting the production environment. Last year I helped two customers migrate over 10,000 servers across the country and across Europe. Automating the process was extremely valuable in those migrations.

The near-zero downtime for migrating from one data center to another has been the most valuable outcome of using Zerto. When you are migrating half a petabyte of data from Texas to Las Vegas, and you're doing that with 3000 servers, you have a limited time to take down the application and bring it up. Our customers like having the downtime minimized.

The biggest improvement would be exporting VPGs and a configuration of VPGs, as well as increasing or improving their IP customization rule set.

I have been using Zerto for seven years.

This is a stable solution. We ran into a minimal amount of bugs and the bugs that we do run into, we have workarounds for.

This solution can definitely scale out very well. I'm looking forward to new improvements in Zerto for Azure. These improvements would definitely make scaling out Zerto much better.

I would rate the support for this solution a ten out of ten. I've called Zerto's support for almost every case that I've needed to. They've been able to resolve the issues in a timely fashion.

Positive

I've used many other options. Zerto is definitely the best of the bunch. Zerto is definitely a lot easier to install than products like Set Recovery Manager, and it includes the replication technology that is agnostic from any storage replication that would be required.

Our customers definitely see a return on investment, especially with time savings, by doing required compliance testing for disaster recovery with a minimal amount of effort.

The pricing is top tier but offers good value. 

I would rate this solution a ten out of ten. 

Our primary use cases were designed around backing up and being able to restore our management plan. This isn't something used for our department users. It is specifically for our infrastructure, things like vCenter, vRealize Operations—all those things that we still have to maintain. We wanted something a little more granular than just a standard backup. We needed to be able to say, "Rollback half an hour or an hour," as opposed to following the backup schedule that the larger backup system provided.

We're using it for migration. Zerto plays a large role in helping us move away from Hyper-V into VMware. We're talking about multiple departments that had to transition their applications and Zerto gave us an opportunity to do it in a much less painful way.

Another key benefit is that our response time has significantly decreased. We're no longer having to rely on the traditional process where you manually execute a backup and hope to God it works okay. And then, you have to run through whatever changes are necessary and cross your fingers that, if you have to restore, it will come back. We don't have that problem with Zerto.

The solution has also helped to reduce downtime for us, absolutely. In most cases, we are able to use Zerto as a momentary backup, run an upgrade or installation, and see whether or not we're going to succeed. We can potentially back it out without anybody knowing about it because it's still within our maintenance window. We never exceed that rather limited time period. That's very helpful. With our existing backup, more likely than not we're rolling into days at a time if something fails. So if our maintenance window was on the weekend, it would roll into the production week and cut into the week by a few days. That would be very problematic.

And the recovery speed is basically as fast as the speed of our pipe, and that's what makes it great. As long as our pipes are fast, we don't have to worry. We can roll in, roll out, or potentially roll back if we have to, within a really small window of time.

In addition, it has definitely reduced the number of operational groups involved in backups. Zerto is not managed by our storage team. It is managed by the team I'm on, which is infrastructure. Because of that, it's all internal to us on the infrastructure team. We don't have to go outside of our team to coordinate with others.

There are several valuable features because of the way we use it. The backup and restore features are definitely indispensable.

There are certain things about the user interface that could be a little bit more user-friendly. But it really depends on the audience. If we are using it as a technical tool, our team is the audience and we are able to utilize it. But if we were to pass this on to, let's say, the department users, that would become a little problematic. I'm wondering whether or not we can actually expand our offering to those department users. That may be a question.

I have been using Zerto for three years.

As long as our infrastructure is stable, it's stable.

All I have to do is add managers out there and it expands. What it boils down to is that my infrastructure has to be able to support it. I have to have space where I can send the backups to. As long as that exists, we're fine.

The customer support is pretty good. The bottom line is that the customer service is responsive, whether we're talking about technical challenges or even licensing challenges. They've been very helpful in both ways.

Positive

We played a little bit with Veeam, but for the most part, we relied on our storage team to provide us with backups. We switched to Zerto because that team wasn't able to deliver in a timely fashion and they weren't able to guarantee restorability.

I wasn't involved in the initial setup. We have an individual who is our infrastructure expert. He took it upon himself to try it out. He told us what he found out when he did that trial and we started playing with it a little bit more and saw how easy it was to use.

I don't want to create upward pressure on their pricing plan, but the pricing is good. It's affordable.

The amount we had to set aside for our existing backup solution, compared to Zerto, was astronomical. The way Zerto works, it is so easy to scale up and out. It's not going to end up creating undue pushback as far as the cost goes.

We evaluated other solutions, with Veeam being one of them.

There's a lot about Veeam that we only just touched the tip of. I can't say with a lot of certainty what specific features Veeam may have. But there's a reason that we only touched the tip of Veeam and jumped over to Zerto.

One of the things that brought us to Zerto was talking to some of the folks that were here, at VMware Explore, years back, about what Zerto did, how it did it, and where it got its origins. That told us it was something that was definitely pretty solid and worth trying. I have to admit that, after trying it, it hasn't disappointed.

Leaving Veeam aside and comparing Zerto with our existing backup functionality, forget it. The two solutions are night and day. There is no comparison whatsoever. There is a lot of overhead with our existing backup feature that we just don't have with Zerto. We definitely have an easier time managing and controlling it. Zerto is definitely easier to use than our existing backup function.

One of the things that I'm finding with Zerto is that we're discovering new uses every day. As we continue to explore what Zerto can do, we haven't even gotten to the point where we say, "We wish it could do X." I'm not quite sure how Zerto interacts with cloud as a target, right now. That's something I need to learn. That's not necessarily a fault of Zerto, it's just me not knowing it yet.

We use it for a hot DR site for our primary production environment, allowing us to fail over all of our production servers in case of an emergency.

We are in a much better position as far as our data protection scheme is concerned, with Zerto. Compared to where we were before, it's a night and day difference, because we didn't have the ability to immediately fail over our production environment. The difference is pretty extreme for our organization. We went from just having SAN snapshots to Veeam backups, and now we have replication.

It massively decreases the time needed for us to fail back because, before, we had no way to do so for our workload. It would have been a manual process to move our workload somewhere else. We would have had to get the VMs off of the existing infrastructure and we would have had to create a whole new infrastructure and get them running somewhere else. That could take two to three weeks, in an emergency situation, with our entire team working on it, versus just pushing a button and moving it right now. We're in a whole different realm now.

There would also be massive savings in manpower to do that. We would have to create a whole new infrastructure, whether in AWS, Azure, or even procuring physical equipment and deploying it. Now that we have Zerto in place, it's there waiting and being replicated too.

The fact that it just works is important to us. We don't have to do a whole lot to it. It does its thing in the background and it's ready to go. It enables us to execute our DR plan at any time that is required. It doesn't seem to require a lot of time or management or day-to-day maintenance. 

It doesn't "complain" a lot and it's ready to go at any time, so you could call it easy to use. It's just me responsible for maintaining it, and there is a network infrastructure person involved as well. But it mostly maintains itself, once it has been deployed.

It does what it's purported to do, which is to provide continuous data protection. We have a five-second RPO. It's definitely doing its job. It's there in the background, replicating constantly.

I would like to see them continuously improve Zerto's automated functions, such as putting hosts in maintenance mode within vSphere and not having to worry as much about how Zerto is going to react. Rather, Zerto should be able to handle putting various hosts, within either the source or destination side, into maintenance mode without having to worry about the vRA appliances. Sometimes, Zerto almost holds the vSphere environment hostage when it comes to taking certain actions. You really need to be cognizant about what you're about to do. They should further automate that and increase Zerto's ability to handle things like that in a very slick, automated way, without intervention.

Zerto could also build more canned automation tools within their product, tools that automatically work with DNS updates to AWS or Azure. Maybe they could provide an area for scripting help or canned scripts, a community or a place where people could grab some scripting. Maybe they could reach into Citrix or F5 load balancer APIs.

Also, if you have a host go wrong or you need to put one in maintenance in an emergency situation, especially on the source side, it can require you to fix Zerto and redeploy vRAs or redeploy the little appliances to the host that they're going to be on.

Also, depending on what resources it has available, storage or vSphere-wise, I'd like to see it able to balance itself out within the virtual environment, with its storage usage on the destination side.

I've only run into these things briefly, so I can't speak about them at the deepest technical level, but I have noticed that they're not as perfect as they could be.

I have been using Zerto for three months at my current company, but I have about two years' experience with it in total.

For the most part, it has been stable. There have been a few points where I have had to delete the VPG group, re-replicate data, and start over, to get things back to a good spot. But overall it has been pretty stable.

We are only protecting 45 VMs. We're not a large, multinational, so I can't really speak about its scalability.

I haven't used the technical support very much.

We didn't have a previous solution, other than SAN snapshots. That's why we looked to put something in place. Previously, we were in a tenuous situation that would make anyone nervous. We went in this direction so that we wouldn't have to be nervous.

It didn't seem that difficult to set up. 

It took a couple of days, but that didn't include setting up the SAN and the secondary sites and all of the infrastructure around having it work directly. But just the Zerto solution itself did not take very long at all to set up.

Everything that we needed to do to facilitate the use of the solution was more involved and took a month or so. At the time, we also deployed a Veeam solution to do the long-term storage, and that was wrapped up in the same project, so it's hard to give an exact amount of time for the deployment. 

Everyone knows Zerto is a little on the expensive side, but what else is there on the market that does the same thing? It is more expensive per client, for what it does, compared to a backup product like Veeam.

We didn't really go into a full evaluation of other solutions. We took the recommendation of our VAR. They're a company that provides us with help in implementing projects. They recommended going to Zerto, and I had already used Zerto before at another company, so I was comfortable with that recommendation.

Zerto serves a very specific purpose in our environment, which is to fail over the entire environment in an emergency, very quickly. Veeam claims to be able to do that, but I don't think it does it as quickly or efficiently as Zerto.

The main thing is to make sure your network infrastructure is designed properly. Zerto is only going to be as successful as the network infrastructure and the automation that is created around it to help with a failover situation.

In our particular situation, we have a stretch network situation, which means we don't really have to do a lot of the automated scripting that most people might have to do, surrounding re-IP-ing the environment and DNS updates. We're in a unique situation. Because we are a telco, we own our entire network and we have the ability to stretch our network to a location that's a state away. That scenario doesn't apply to a lot of other business situations. Other institutions may not have that luxury, in which case their scripted automation, and how well that is set up, would be critical.

Because we weren't doing backup and DR management before, Zerto has probably increased the amount of staff we need. You don't need staff in place for things that you aren't doing.

HPE bought Nimble and made Nimble not as good. Hopefully, the HPE acquisition won't have a negative effect on Zerto. That's a deep concern among all people who have had to deal with things that HPE bought. They need to keep to the original intention and vision without diluting it within some other HPE product or some other HPE offering. I have no interest in seeing Zerto losing its functionality or having it rebranded as some other problematic HPE solution. We bought this as a purpose-built solution to do exactly what we want and that's the way we would like it to stay.

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.
