Zerto Reviews

The primary use case is disaster recovery. 

The biggest benefit is the application-consistent disaster recovery functionality. 

The most valuable features include the ease of use and the usability of the user interface. Long-term, the solution has proven to be very resilient and stable. It meets our DR needs for VM environments. 

The near-synchronous replication is a great feature. You have near real-time DR capabilities. In the years I've used it, we've had application-consistent profiles. To meet the recovery point and recovery time objectives, it helps to have that on hand. 

It's affected our RPOs positively. It totally meets them via near-synchronous replication. That means the VM stays in a consistent state and is always available. 

Zerto could improve its reporting capabilities. That's lacking. The alerting capabilities are lacking as well, partly due to the fact that there's no way to trim down the alert fatigue if there are failures within the application. It will send out alerts consistently instead of spreading the alert times every 30 minutes, hour, et cetera. 

We've been using Zerto at our organization over the past eight years. 

The solution is very stable. 

I cannot comment on scalability. We only have two Zerto instances installed, one in production and one in DR. We haven't had to scale out or to the cloud. 

We are protecting upwards of 100 virtual machines. 

Zerto's support is good. They are responsive from an email perspective. I've never had to pick up the phone to call them for anything beyond our DR testing every year. In those cases, we do open a proactive ticket in the case that we run into issues with recovering virtual machines. 

Positive

We did not use any other solution previously. We chose Zerto since it was an application we inherited. It wasn't something I specifically chose, however, understanding the industry, we know that it is the top player in terms of software recoverability for virtual machines. 

I did not initially set up the solution; I inherited it. However, over the past eight years, we have gone through a number of upgrades, which for the most part have gone seamlessly. We did have a few issues in the past that support was able to fix in a timely fashion. 

I'm unsure if the company has witnessed any ROI. We have not gone through any TCO analysis. 

The licensing is outside of my purview. 

I'd rate the solution nine out of ten. If the reporting and alerting functionality were better, I'd rate it ten out of ten. 

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 have approximately 1500 to 2000 Hyper-V machines. Those Hyper-V machines are being used and converted to VMware. We use Zerto for our conversion from Hyper-V to VMware. We are also considering using it for DR purposes. 

Our prod environment runs on-premises and we have a DR copy of everything that we run in production. Our development runs on machines and hardware. In the event of a DR event, we would shut down dev and bring up our secondary copy of production. We hope that Zerto is going to be the tool to help us do that.

Zerto offered us massive time saving and consistency. We have a consistent outcome every time we complete conversions. We move from one platform to another with different loads being moved each time and Zerto's results are consistent each time.

We convert 30 to 50 VMs from Hyper-V to VMware on a nightly basis which has resulted in saving time as this is good throughput. Zerto also helped to reduce downtime. If we were to do this manually, we would have a lot of downtime to shut down those VMs on Hyper-V to be able to do the conversions.

The ease of the conversion moving from Hyper-V over to VMware is the primary reason why we chose Zerto and is its most valuable feature.

There has been one pain point that we have run into. We wanted to shut down the dev environment to focus on the prod environment. We couldn't find any option in Zerto to do that.

We have been using this solution since the start of 2022. 

This is a stable solution that offers consistent results. 

From a DR perspective, we use a few solutions. We have multi-site data centers in our environment along with Cohesity. We use Cohesity from a backup and DR perspective.

If you're in the middle of conversion between different platforms, regardless of if you're moving from on-premises to host it or from one environment to another, Zerto is agile and able to move your workloads into different environments pretty easily.

I would rate this solution a nine 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.

Zerto is part of our disaster recovery plan. We have it set up in our main office and in a remote location in another state. We replicate all of our ERP data over to the replication site utilizing Zerto. In case there's a failure or a ransomware attack, or anything that we need to restore back to a point in time, in real time, Zerto covers those scenarios.

Being able to bring a virtual machine online in a test environment, look at it, make changes and then say, "Okay, we're done," and turn it off again, is pretty helpful for us. It has actually saved us a couple of times.

For example, we had an order that was put in by a customer but the entire order got deleted. There was no history of it and no way of retrieving what was on the order. So we actually spun up our production ERP system on our remote location, utilizing Zerto. We brought it online and restored it to the point of time when we knew the record was there, and made a screenshot of the record with all the line data included. Then we shut it back down. We were able to re-key the order and it worked out great.

With Zerto, our disaster recovery is probably the one piece that we know is reliable and available. The way Zerto works, and the way we are utilizing it as part of our disaster recovery solution, make our disaster recovery plan very easy to explain for us and to our auditors.

In addition, when we need to fail back or move workloads, Zerto decreases the time it takes and the number of people needed. A failback literally takes minutes to do, and one person can do it. We can either put it into production or just say, "Okay, we've got what we need." We'll just end it and go back to our normal production cycle. It's very easy and definitely decreases workload. There are no tapes to dig out or backups to sort through. You just grab the time you want and say, "Hey, put me back into this period and time," and it does it.

Zerto's continuous data protection is unmatched. It's phenomenal.

It's also very easy to use. The menus are self-explanatory. Once you understand the terminology of the product, what the VPGs (Virtual Protected Groups) are, you're able to pretty much do what you want in the product. It's very easy to use.

It took me a little bit of time to get used to Zerto's terminology and to relate it back to how you do a backup traditionally. It was a little different. It took a little while to understand what a VPG is and what it does. That's an area that they could probably improve on a little, making the documentation easier to understand.

I have been using Zerto for two and a half to three years.

The stability of Zerto is outstanding. It runs 24/7 and works as described. If there are any issues or any problems arise, we get notifications from Zerto, but that does not happen often. Usually, if there's an issue, it's related to something we've done, or because we need to increase a file size or job log. Other than that, it works the way it's supposed to.

Zerto covers 10 production machines in our environment, which is not a huge scale. We only have one replication site. We could easily add more replications if we wanted to. Zerto has that flexibility. But for us, a one-to-one replication to our Nashville location works perfectly for us.

I have had to call their technical support and they're very responsive. The issue is always resolved. I give them very high marks for their support.

Positive

We didn't have a solution that does what Zerto does.

The initial setup was very simple, very straightforward. Zerto got online with us when we did the initial configuration and gave us easy guidelines to follow. We were able to have it up and running in less than an hour.

We took what Zerto recommended in their deployment guide. We knew the areas we wanted to cover and what we wanted to improve upon. Based on those things, we were able to come up with a nice, easy plan to follow to get it implemented.

When there's an issue, just one person is involved, but generally speaking, there's not much maintenance on Zerto. Once you get it up and running, it does what it's supposed to do.

We have definitely seen return on our investment in Zerto. First, it's a time-saver. Second, for IT, it gives us peace of mind. We don't have to worry about it. 

One of the ways Zerto is really good in that regard is that you can actually bring your servers online in your test environment and see exactly what something would look like if you restored it. And if you don't want to restore it, you just hit "cancel" and it puts it back the way it was. It's great to be able to do that. The test features they have built into the product mean you can test a scenario like "What if I want to spin this up over here, how would it look?" You can do that.

Licensing Zerto was very simple. They had a product that fit our size and scale. It made it really easy to choose. 

As far as pricing goes again, we're a $150 million dollar company, meaning we're not a huge company but we're not a small one either. Zerto had the right pricing model that fit our budget, and they delivered on it.

Zerto was the leader in the category, and I'd used it in the past with another company, so we just went straight to Zerto. There was no need for a PoC with another product. We knew it would work for us.

My advice about Zerto would be "do it." The product is just that good. What it does is very impressive. And again, it gives you peace of mind, knowing your data is safe and secure and that it's replicating like it's supposed to. That's just a great feeling.

We don't do long-term retention currently due to how our backups are made. We use Zerto for anything less than a one-week window and we can revert back. 

Thankfully, we have not had to use Zerto for ransomware, but it would absolutely be a lifesaver should that scenario come up. Similarly, we haven't had a situation where we had to fully flip over to our DR environment. We have tested it, and it works great. Our recovery time would literally be 20 minutes and we'd be up and running in a brand new location, without missing a single record.

While Zerto hasn't necessarily changed the amount of staff involved in our overall backup and DR management, it has definitely made those tasks very easy. We set it up once and we don't have to worry about it anymore. It runs and does its thing. We don't have to babysit it or watch it or worry about it. It just works. For what we use it for, I don't see an area in which I would say, "Hey, add this feature or make this change." It works as described, right out-of-the-box.

For one client, the use case was to facilitate data center migration, and for another client, it was for failover and failback of the data center for DR. We wanted to have controlled failover and failback of related applications for DR.

We have not used it for disaster recovery in the cloud. Everything has been on-prem so far.

Zerto helps in automating disaster recovery capabilities. It allows automation and orchestration of complex activities.

We have used Zerto to help protect VMs in our environment. Zerto’s overall effect on our RPOs has been pretty good.

It has also been effective for our RTOs.

Zerto has helped to reduce downtime, specifically for failover and failback, but it is hard to qualify the time saved.

Zerto has not saved us time in a data recovery situation due to ransomware or other causes because we have not been impacted by any such issue.

Zerto has helped to reduce the organization's DR testing. There is about 20% reduction.

It has also reduced the number of staff involved in a data recovery situation, but I have not seen any reduction in the number of staff involved in overall backup and DR management.

Its ease of use and scalability are valuable. 

I also find the near-synchronous replication to be valuable. It is extremely important for organizations.

There should be more comprehensive cyber recovery capabilities.

I have been using Zerto for two years.

It is stable.

It is scalable. It is deployed across multiple locations. There are roughly about 4,000 VMs.

We might use it to migrate to cloud solutions. It is to be decided.

I have not reached out to them myself.

We were using SRM. We switched to Zerto for automation.

Zerto is highly effective in terms of ease of use as compared to other solutions. Zerto is also pretty effective in terms of its speed of recovery.

We can easily migrate data using the Zerto console.

Zerto has not yet replaced all of our legacy backup solutions but it will.

Our setup is all on-premises. I was involved in its deployment to some degree. It was pretty straightforward to deploy.

It took about three months. It was an enterprise-wide solution.

It was a combination of in-house staff and a third party. The third party was a VAR or value-added reseller.

It required just a handful of staff for deployment. It does not require any maintenance from our side.

We have seen an ROI, but I do not have the metrics.

It is not a bad pricing model.

We evaluated other options on paper, not physically.

Zerto is an effective tool for automation and orchestration of complex activities.

The biggest lesson that I have learned by using Zerto is the need for application involvement and defining protection groups.

Overall, I would rate Zerto a nine out of ten.
