Zerto Reviews

We're using it for site plate replication and fail-over or disaster recovery. We're primarily using it to replicate between the data centers that we own and operate.

We've had a few disasters where we've had a site go out and we've had outages or hardware failures. However, with a single click, we can have all of the failover and when the other sites come back up, it can auto re-replicate in the reverse direction so there is no extra manpower required. Whereas, normally, we would be spending hours and hours cleaning up from the failover event.

We enjoy the simplicity of not only configuring replication but failing over with a single click and then having it automatically reverse replication. We've had other products such as Veeam, and their replication works, however, it's very cumbersome to configure. When you failover, there's a bunch of work you have to do after the fact to reverse the direction and to restore the VM and how it names it and which environment it shows up in.

In terms of continuous data protection, it's the best product that we've found that does this. It's not snapshot-based. It's continuous, so there are no specific points in time we have to worry about recovering to or from. It's pretty much any time, as long as it's within our replication window.

The solution is very easy to use. It's very straightforward. You don't really have to do a lot of reading through the documentation, or things like that. You can basically scroll through the menu and figure it out.

We have not had ransomware, so we haven't had to deal with that, however, we definitely had a disaster recovery issue we had where we had the fail-over site stop unexpectedly. It did save us a bit of data loss, whereas, normally, we would have lost six hours' worth of customer data. In this case, it was seamless. We lost seconds' worth.

The solution has reduced downtime. It has done so a couple of times. There could be some cost savings there. It's just not something we calculate.

The backup solution needs to be improved. From our perspective, Veeam and Zerto were competing products. They both do very unique things that they're very good at. For instance, Veeam can do replication well. However, it's really a backup product. Zerto can do backup, and yet it's really a disaster recovery product. It would be great if they could improve upon the backup functionality, or continually improve. We've seen some improvements, however, if they continue improving upon that it may eventually eliminate the need for the other product.

I've been using the solution for about three years.

The solution is very stable. We haven't had any issues. The only issue we had was a DHCP issue where we didn't static a couple of the DVMs, which is the agent for each ESX host, and we were having a few gaps in replication when the IPs would change, however, we've stacked those and that has resolved that issue.

We find that it's very easily scalable. The resource overhead is very minimal so it's really easy to scale up the environment and the product kind of automates the process for you. You select where you want it, hit install, and it handles it for you.

About five people use the product in our company. We have some system administrators, we have a couple of programmers and we have a DBA.

We have around a quarter of our environment replicated with Zerto. It's mostly our critical infrastructure.

We may possibly increase usage over time.

Technical support is good. I'd give it an eight out of ten. They're pretty quick to respond. They are almost always able to resolve my issue. I have no complaints. I only had a couple of support tickets, however, the experience was pretty good.

That said, their web portal is a bit clunky to navigate. For example, putting in a request, knowing where to go, or pulling up documentation or upgrading information wasn't quite as intuitive as it could be.

We are still using Veeam mostly for backup tasks. We use Zerto for site recovery.

The initial setup was very straightforward and easy.

The installation was simple. There are lots of guides and information. There are YouTube videos. They had training classes that were free that you can go to and they have a little lab environment. Even without the assistance offered, the way you install it is very straightforward and very simple. Really anybody can run the installer and have an idea of what they're doing right out of the gate without really any training.

Deployment took around a day.

We did have a specific deployment plan and we were able to execute that in about a day. Getting all the sites set up and then the VMs replicated was fast.

We have five people on staff that can handle deployment and maintenance.

We didn't use an integrator or consultant. We just did it ourselves.

There's not a direct ROI as it's being used as an insurance policy. The only time it really benefits us is when something bad happens.

It's reasonably affordable. Obviously, cheaper would always be better, however, it's not out of the expected range. We are just paying by VM. It's my understanding there are no extra fees.

I can't remember the companies off the top of my head as it's been a few years since we've done it, however, we evaluated five or ten different options that were popular at the time. Some of them were integrated with hardware. Some of them were software only.

In the end, it came down to Zerto due to simplicity. It's very simple and straightforward. It removes all the overhead of management and knowing what is active or what's the standby copy. It handles all of those pieces for you.

We're probably on the latest version or one version behind.

We very lightly use the product for very specific things. We have a couple of things that are very high data rate, very high IO, for which we cannot use traditional snapshot-based technology and we are using that to do a long-term backup.

The solution has not reduced the number of staff involved in data recovery situations. We have maintained exactly what we had. It's simplified it so it's possible to have a reduction, however, we haven't done any reduction from that.

The biggest piece of advice I could give is if you want the best-in-class for failover and replication, as well as ease of management, there is no better product that I've seen so far. Whether hardware or software combinations, this has been the simplest deployment and it just works.

I'd rate the solution at a ten out of ten.

One of our biggest use cases has been migrations. We migrated the virtual machines in one of our data centers using Zerto.

We're in the middle of a migration that Zerto has made much easier. We also use it for many standard disaster recovery cases. It constantly keeps our services running.

Zerto's near-synchronous replication is a key component. It's essential.

Zerto enables disaster recovery in the cloud, which is very important. It creates another level of protection to have an alternate location outside of on-premises.

It helps protect VMs in our environment. It's certainly better than a traditional nightly backup.

I've found the migration feature very valuable. It starts like a disaster recovery scenario where you're just replicating the VMs. Then it all gets synced up, and you decide when to make the cutover. 

This is instead of having to do a more traditional conversion of the VMs or shutting them down and migrating the data, which is less efficient.

The seamlessness of a cutover is very helpful.

I have been using Zerto for around five years. 

It offers good stability. 

We haven't scaled it too much, but in our experience, we haven't had any issues with it.

We still use a different disaster recovery solution but for different use cases. 

Zerto didn't completely replace our other backup solutions.

There are cost savings for the migration in particular.

From the migration standpoint, they're flexible with the licensing. You own the license and can apply it to a machine and then pull it back, apply it to another machine, and so on.

For the migration piece, we evaluated different solutions but not for the disaster recovery replication. We knew from the migration piece that it would work well.

For me, it's a ten. I haven't had any issues with it so far. 

We've been using Zerto for data center migration, but we will begin using it for disaster recovery. Because of some data center issues, we're still using version 9.5. One of our data centers is at 6.5 and the other one is at 7, so we can't move any or upgrade to 10.

Zerto enables us to set the IPs and map everything out in our environment prior to migration. We can create VPGs and mass migrate applications, databases, and web clients. That was the selling point for us. The product is easy to use. We had a 30-minute onboarding process from our sales engineer, who showed us how to use it. 

We don't use near-synchronous replication yet. It will be essential when we start using Zerto for DR, but it isn't a big deal during our current migration. Once we have a DR site, it will be essential to have those time slots we can restore to in the event of malware and ransomware. 

Right now, if you have an error, it creates a link that takes you to a website to review information about the problem. It would be nice if Zerto could give you information within the app instead of referring you to a web application.

Zerto for two years.

Zerto is intuitive. We could set everything up in the environment within a day and a half and start migrating on the third day.

I rate Zerto 10 out of 10. 

Our main use case for this solution is the data center migration. We are in the process of moving from our legacy data center and all the VMs into our new data center.

In the future, we would like to look more into disaster recovery using Zerto but that's a much longer process and we are still looking into it.

The speed of recovery with Zerto is at least five to ten times faster. It helped us reduce downtime during migrations. There would've been a lot more downtime had we done a standard migration across data centers, powering everything down. This downtime would have cost our company millions.

The ease of use and simplicity in moving things without having to do a cross vCenter V-motions has been most valuable. It saves time and effort and it eliminates mistakes. This project would've been years if not for Zerto. We completed it in months instead of years.

The licensing is confusing and complicated.

I have been using this solution for two years.

This is a stable solution. 

This is a scalable solution. We used it for our biggest data center and it handled it just fine. We haven't personally had to scale it up, but if we needed to, we definitely could.

Support has been pretty good. I would rate it a nine out of ten. 

I personally have not used other solutions other than just what's built into VMware. When comparing the VMware native solution versus Zerto, it's night and day. It's much simpler and straightforward to set up.

The initial setup is straightforward. It is streamlined with simple instructions. Anybody can do it as long as they understand their infrastructure.

We had a contractor that we brought in to help us with it. 

We have seen return in our investment with Zerto due to the speed and usability and being able to do this huge project with limited hiccups.

I would advise others that the cost of this solution is justified based on the value you receive. 

I would rate Zerto a nine out of ten. 

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. 

We have Zerto as an emergency backup if we were to lose electricity or compute.

I purchased Zerto because I wanted to get a return to operations and to minimize the downtime.

The return to operations is the most valuable feature because it decreases the amount of time it takes us to recover. 

Zerto is the best of breed when it comes to providing continuous data protection.

It has a number of features rolled together. So when we need to failover, it does it successfully without a lot of stuff that we have to tune underneath the scenes. We use Zerto for the short-term retention of the data.

I would rate its ease of use as an eight out of ten. It has made it a lot easier for us to failover. Usually, in the past, we had to manually go and bring things up and this automates it.

The solution decreases the time it takes and the people we need when we need to fail back or move workloads. It saves around eight hours and one person. We had started off with two to three people.

It could save us time in a data recovery situation due to ransomware or other causes but we haven't used it for that.

We haven't had something where we had to recover data using this product, but I assume it would reduce the number of staff involved in data recovery situations.

It has helped to reduce downtime in testing but we haven't had a serious issue where we had to switch over and use it.

The documentation needs improvement in terms of the setup, getting enough detail, and getting that up to speed.

I have been using Zerto for about a year. 

We found Zerto to be pretty stable.

We haven't had problems with scalability.

We don't really have users. We just have data that we move over which is basically the size of the campus.

We need at least one full-time employee to run it.

It's used for all of our failovers so it's in 100% usage.

I have had a little bit of experience with their technical support. I don't have any issues with them.

The ease of use, compared to other products, is much better. Zerto is all-encompassing. 

We had to work on it for about a week to get it running the way we wanted. It took so long because of the fine-tuning. We could have set it up within three hours or something just as a test to see at work, but not necessarily do everything we wanted to do.

The time it took to sync the data up took a little bit longer.

We'll probably see ROI in around three years. 

The pricing is more expensive, but the functionality is what we wanted.

There are no additional costs to standard licensing.

We also looked at Druva. We liked the flexibility that we get with Zerto. 

You'll be happy with Zerto.

The biggest lesson I have learned from Zerto is to be patient. 

I would rate Zerto a nine out of ten. 

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

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

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

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

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

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

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

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

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

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

I have been using Zerto for about six years.

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

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

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

Positive

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

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

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

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

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

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

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

We were able to replace most of VMware SRM with this solution. It allows us to failover individual machines or application clusters with ease. The one thing that it does not do nicely is a full site failover. We have never needed that aspect though (only for testing).

We have leveraged the individual server failovers a number of times, and it has saved us a lot of man hours (doing things such as rebuilding, fighting viruses, or forcing more servers to failover than we wanted). It has been a phenomenal addition, and proved its worth in the pilot phase, when it saved us from having to rebuild a machine that was included in our pilot trial.

Journaling allows us to leverage Zerto's journal for sub-minute recoveries, instead of having to wait for the storage array to replicate. The solution is well worth the money invested.

The full site recovery is not up to SRM standards. Within a VPG, you can do great failover timing as well as ordering and scripting, but if your site contains many VPGs (as mine does), then it is difficult to manage failing over between sites, especially if you are at the site that was impacted.

None. Even the upgrades are speedy and easy. 

None. As long as you have the licenses, it goes smoothly.

I have contacted their vendor support in regards to backup performance of SQL databases. They provided me with adequate instruction and background information to be able to adjust my environment to better suit Zerto's processes. It's been smooth sailing since.

VMware Site Recovery Manager. We changed from this vendor because we hit the 75 license threshold and were forced to consider the conversion to Enterprise. We searched the marketplace and Zerto was a great fit for our needs.

It was straightforward and easy. I was able to install it myself without any help from Zerto.

In-house was all that was necessary. It only required one engineer to work for about two hours to install everything, and then a week to configure and protect the entire environment. This will vary depending on your link to your DR site.

The cost is steep, but once you experience recovering a single server along with its granular restore times, you will see that the cost is justified.

We evaluated Unitrends.

Make sure that you understand the limitations of any software before you dive in. Make sure you document your use cases and have the vendor show you how it can perform those tasks.
