HPE Zerto Software Reviews

We have three locations. We replicate circularly around all those locations for all our VMs. This is for DR.

We don't have to spend a whole lot of time worrying about DR and whether or not we are covered. Zerto just works. As it is replicating, we don't need to spend a whole lot of time with it. That is a huge benefit as far as daily management.

Luckily, we haven't actually had to do a full failover. We have tested it many times, and it proves out okay, but we don't have to spend a lot of time managing it.

Our insurance companies provide assistance with staff or boots on the ground. Whereas, using Zerto has allowed us to act very quickly with just our current team. We can fail over and switch over to our disaster recovery site, instead of having to bring in a bigger team.

It is amazingly simple to use, monitor, look at, and utilize. It is great for that.

We would like more mobile options. If we are at a restaurant or out and about in our normal daily lives, we would like to be able to interface via our mobiles.

I have been using it for about five years.

Scalability is simple. If you just add more virtual managers, then you are good to go.

Our customer rep, success manager, and engineer are great.

Luckily, I haven't had to use the technical support that often. The times that I have, it has been fantastic. They quickly had me where I needed to be, which is top-notch and good.

I would rate them as eight or nine out of 10. Nobody is perfect.

Positive

It gives us peace of mind. Before we had disaster recovery and long-term retention protection against ransomware, it was one of those things that kept us up at night.

We previously used VMware Site Recovery Manager (SRM) and Veeam for backup. Zerto is way better and more friendly. Zerto's interface, simplicity, and reliability are definitely better than SRM.

When we were using SRM, it didn't have a web interface. Zerto's web interface makes it easier to navigate. When we used SRM, it was an actual application. It was a bit clunkier and a lot more difficult to use. However, it has been awhile, so it might not be a fair comparison at this point.

The initial deployment was pretty simple. The implementation took less than half a day. It has been awhile, but it was very seamless, easy, and did not take very long. We were up and running pretty quickly.

Zerto was involved with the initial deployment. We paid for their Professional Services, who walked us through the whole thing. It was very simple.

Our technology committee established an RPO and RTO. We beat those times with Zerto. We have a 30-minute RTO and we can recover within seconds. We have far exceeded any expectations so far.

From the simple point of not having to worry about whether or not we are protected in the event of ransomware or disaster, it is worth the money.

The pricing seems fair.

We looked at other solutions around five years ago.

I would recommend buying it. It is easy and simple. It works. It is all the things that any administrator would want. You don't need to spend a lot of time messing with it and you can sleep at night.

I would rate this solution as eight out of 10 because nothing is perfect.

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 use it for disaster recovery, by replicating to our DR data center.

It has simplified our disaster recovery plan. With VMware SRM it was a little bit more complex. Zerto adds more granularity, but not at the expense of complexity.

The most important features are the 

• simplicity of recovery 
• wider capabilities and feature sets than SRM has.

I have been using Zerto for about three years.

We've been using it since version 7. Since then, it's gotten better and better. We've had some bad experiences with DR tests where everything went sideways and we had to restore a bunch of VPGs or recreate them. It seems like those situations are happening less and less as the product develops.

We have 1,200 seats and we have about 1,000 VMs that are replicated. So far, scalability hasn't really been an issue. We haven't run into a problem scaling it out.

I haven't been a super big fan of the support area. The support could really be better in terms of responsiveness. I've had some issues that took two or three days to get resolved. Once I got to the right person, they were resolved quickly, but it took a while to get to that person.

On a scale of one to 10, today I would rate their support at about a seven. If you had asked me two years ago, I would have rated it at three.

Neutral

We were an SRM customer and moved to Zerto. We had issues with SRM and I think we had some issues with Zerto initially. We've had it for three years and we've gone through several revisions. With every revision, it seems to get better. They keep adding feature sets.

SRM and Zerto are really the primary competitors. We like the fact that Zerto does VM-based replication instead of having to involve storage-based replication. You can just point to an instance of it and say, "Replicate to this DR data center," whereas SRM is a little bit more complex in that context.

The speed of recovery between Zerto and SRM is similar. With the later versions of Zerto, the recovery speed has become a little bit faster.

It's very straightforward to set up. You just install the software and point it at your vCenter. There are not really a lot of overly complex parts to the installation. It installs relatively easily and quickly.

We did it ourselves.

We haven't seen ROI because we've not ever had to recover anything. But in an instance where we would have to recover from a disaster, we would definitely see ROI. It's like paying for insurance. You don't really see any value in it until you need it.

The licensing is a little bit steep, but there is some value that you do get for it as well.

In our usage, Zerto has not helped to reduce downtime or the number of staff involved in a data recovery situation. It also hasn't reduced our DR testing. We do a DR test regularly and that is about the same as it was.

I don't have any advice, but I would absolutely recommend it. The simplicity of how they have laid out the VPG structure, and being able to separate those out into groups, as opposed to SRM where you're replicating everything, seems like it's really well designed.

I've used it for a temporary migration. We had to shut down a data center and we moved some database servers over to a disaster recovery site. We then did the maintenance at the data center and brought them back.

We're using it only for on-prem and we use it to replicate from our onsite data center to a co-location, but there is a fiber connection between the two, so it isn't an internet-based replication.

In that migration instance we had six terabytes of data that we needed to protect and bring online quickly. We had a replication going and we made the protection group switch and brought the systems back within less than 30 minutes. It reduced our downtime on some critical applications.

If we hadn't used Zerto, we would have had to vMotion them to the other side and that could have taken hours. That could also potentially have been unreliable because there's a timeout period when vMotion works. We used Zerto to be safe.

It is pretty simple to use.

Whenever we do a failover, there's a confirmation box that shows up later. It's a little hard to see sometimes. We'll do the failover and some preparation activities and then there's a checkbox you need to check to continue and sometimes it's small, in the corner, depending on which screen you're using. A popup to continue would be a little bit better because then you're not sitting and waiting for something and it's already there.

We also had an issue with a misnamed network. They should make that a little more apparent when it's not available on the destination side. We were able to go all the way through with it, but when we did the recovery, it wasn't available. A pre-check to say, "Hey, it's not available. What network do you want to use?" would be helpful.

I have been using Zerto for about a month because I'm new with my current company.

The stability has been alright. We have failed over quite a number of machines.

We did have an issue with one failover. It didn't fail over completely. You really don't want to have to contact support in those situations, but we had to. It could have been an issue on our side as opposed to something being wrong with the configuration. I don't know what happened, but they got it working.

We had to call support during that migration because one of the settings wasn't correct. I don't know exactly what went wrong, but we had to create a ticket. Zerto got back to us within an hour, so we were really impressed with the support from them. It was really good. They got us taken care of pretty fast and we were back online during the process, within an hour. They were quick to respond after we submitted the ticket and then they got it fixed. There's not really much more they could have done in that situation.

Positive

We use VMware-native as well as Zerto. It's all circumstantial, based on sites. Some sites ended up getting an SRM license, so we have kept them instead of wasting licenses. And some sites use Zerto. Maybe down the road we'll pick one of the products, but for now, we use both.

Zerto was already there when I stepped into the picture. I helped initiate some of the disaster recovery processes. Based on what I saw from the outside, it was easy because it was ready for that situation quickly. It was ready in a business day or less, aside from the replication aspect or the data sync from when you first set up the jobs. But the basic setup to get things going was ready within less than a business day.

I would think we have seen return on the investment in Zerto because we use it a decent amount of the time. We have reduced the downtime within the last month because of it as well.

We've used SRM from VMware. Personally, I prefer Zerto because it's a little more automated. VMware has more requirements and VMware tools get us stuck sometimes. If the VMware tools aren't working on a virtual machine, it won't replicate over as quickly or start up as quickly because it's waiting for that service. You have to do custom settings to avoid that. Zerto doesn't have that requirement. It's a little more click-and-go versus click-and-monitor and then trace back and see what went wrong.

Zerto is also probably faster because SRM waits for VMware tools to come up and say, "Hey, we're here." That's not a requirement that I know of, with Zerto. Maybe it is. I'm a newer user of the product.

In terms of the number of staff involved in data recovery situations, Zerto hasn't really reduced that. My team generally handles those situations and it's the same number of people, regardless of which product we're using.

Zerto worked and did its job and it was easy to use. My team liked it, and the database administrators, who were the customers in that instance where we did the temporary migration, appreciated it.

I would rate it at eight out 10. Sometimes the interface can be a little tricky. If you're using a disaster recovery application, you're in a stressful situation already. Sometimes there are a lot of confirmations you have to go through just to start the Virtual Protection Group, and then it starts and you have to confirm again a few minutes later. You're stressed out. You're talking via chats with a bunch of people and there were times where that prompt was probably sitting there for minutes, which cost money.

More confirmations upfront and removing that second one later on in the process would be good, or a popup, instead of it being a small checkbox in the corner of the screen, is my recommendation.

I primarily use it for disaster recovery backup. Also, whenever we need to move things between our different environments, e.g., moving it to different vCenters and Azure, that is primarily done through Zerto

We are in the process of doing a disaster recovery test soon, and Zerto is at the forefront of that. Zerto is really helping out with this. The bigwigs, who don't know anything about technology, come to us and then we explain Zerto to them. Whenever we simulate failures, Zerto has been able to seamlessly and instantly recover. This really gives our team big brownie points.

The most valuable feature is Instant Recovery. Especially when a server needs to be moved over in a crisis situation, Zerto has been there to help me out in a pinch. It is really fast and responsive. It is always there when you need it most.

It is great for reliability. 

I have had problems with vRAs. When I am trying to restart a host, sometimes the vRAs will hang. I would like it if they wouldn't migrate off or shut themselves down, then I have to manually work with it a lot of the time.

I have been at the company for about six months and using Zerto the whole time.

It is pretty stable. The only problem I have is with the vRAs sometimes freezing up. Other than that, it has been pretty stable and reliable. I feel like we can count on it.

It is very scalable. I feel comfortable with it. if we needed to expand in an instant we could.

I have only used our customer support for upgrades, but they have been great and helpful. I would rate them as 10 out of 10.

Positive

If I have networking issues on one vCenter, then I can just Zerto it over to another vCenter. This instantly fixes the problem, saving us time and money. In one case, our phone system was down because we were having a network issue at one of the vCenters. So, I just moved the machine over to the other vCenter through Zerto. It came back online, bringing us back up.

It is way faster than just manually moving VMDKs, etc. It saves hours of time and a significant amount of money.

I can compare Zerto to Rubrik's instant VM recovery from our backups. Zerto is faster. Since Zerto is instant, it is always watching while Rubrik has to take time and restore everything.

The solution is really good. I am super happy with Zerto.

I would rate Zerto as 10 out of 10. They are great.

We've been using it to consolidate data centers. We have 13 hospitals and two main data centers and a cloud presence. We're trying to collapse everything. We've been using Zerto to move the workloads over to our primaries.

It's allowed us to save a lot of money by collapsing a few data centers. We have been able to evacuate the hardware in the one data center in our virtual environment, and then shut down and get rid of all those hosts. And it has saved us time in our failovers, from collapsing data centers to our primaries. It enabled us to do that on the fly.

One of the valuable features is the ability to re-IP on the fly, because it makes the migration a lot smoother on the system end.

The syncing of the replication needs improvement. My experience has been that, every once in a while, when you go to do a failover, it tells you it's not syncing. Then you have to troubleshoot and figure out why it's not fully synced up.

I have been using Zerto for three years.

It's pretty stable.

I've never had to use the technical support.

We use VMware SRM pretty exclusively for our disaster recovery stuff. SRM and Zerto are very similar in the way they work. Zerto enables features that SRM doesn't give us and that's why we purchased it.

Also, it takes half as much time to failover with Zerto as it does with SRM. Every six months we do a failover of our Epic environment from one data center to another, and we use SRM for that. We've been using Zerto for failovers from one data center to another for data center consolidation, and those seem to happen a lot faster than SRM.

We've definitely gotten our money's worth out of it for what we've been doing. We have been able to close three data centers so far.

We looked at Veeam, but that was a long time ago.

We use it to protect VMs. Disaster recovery is our use case. Our compliance requires that we need to simulate a DR exercise every six months if we are protecting a VM. One of the features of Zerto is simulating a disaster recovery exercise in case of failure. We fail back the VM to the DR site, and when the event is over, we fail it back to the production site.

We are using one of the newer releases, but we are still six months behind.

It meets our SLAs for RPOs and RTOs.

• Replication
• Failover and failback for DR

It needs more documentation and automation features. I would like more documentation on designing an environment and network operations. On the automation side, I would like automation to clean up the environment in cases of a failed DR effort. An API interface to perform the DR exercise would also be nice.

I have been using Zerto for seven years.

It is stable. We have had no big problems. 

There have been a few minor upgrades.

It is scalable. From a few hundred to 5,000, it has been pretty easy to scale, not only horizontally, but also vertically.

Zerto is protecting a couple thousand VMs.

The support is very good with quick response times. They are helpful. If you open a session, they will take over and immediately solve your problem. I would rate them as nine out of 10.

Positive

We have used SRM and Veeam. 

Zerto is a better product. It has more modern features. It is easy to use. It also has a good interface with command line for scripts.

The initial setup was very straightforward. The solution is easy to implement. You implement it and it starts working out-of-the-box. There is not much configuration required. It takes a couple of hours to have it up and running, protecting you.

We deployed the system ourselves.

We have seen ROI with the RTOs, RPOs, and speed of recovery.

Using Zerto, you can have your VM up and running in a matter of minutes. All you need to do is flip a switch, then you are good to go.

For speed of recovery, Zerto is faster than SRM. SRM takes more time and needs some manual effort. Veeam is pretty good and on par with Zerto.

Do a PoC. You can compare it with other products, like SRM and Veeam. Then, you will see that difference. It is good to have the solution working in a lab. Or, engage Zerto who can assist you in building a lab for it.

I would rate the solution as nine out of 10.

Right now, we use it just for disaster recovery.

We have always had a centralized data center. Therefore, if we were to lose connectivity or power, then access to county resources would be cut off until that issue is resolved. If there is a hurricane, it would be the same thing. If we lose power, then we would be down until something comes up. With Zerto, I can quickly get us up and running at the disaster recovery site, provided it is still operational.

For most use cases, the failover time is a handful of minutes, if that. A single user can run the system.

Zerto will reduce the number of staff involved in a data recovery situation. As of now, we have been lucky. We have not had to deal with this type of issue. However, it will require less people going forward. So, I can dedicate people to other tasks in a situation like this.

Disaster recovery would initially require four or five people to handle just the server side. This has now been cut down to just one person.

It provides great continuous data protection. The RPOs on things are in seconds.

We have been using it for two years.

We haven't had any issues. It literally just runs. Once you have it set up, you just leave it alone.

As long as I have the resources and licensing, I can keep going from a scalability perspective.

The tech support on my latest issue wasn't so great. I had to figure a lot of stuff out myself. It could be that I had a Level 1 tech who was new or something, but it seemed like the tech was spitballing, which does not help me.

In previous instances, the technical support was great. They were able to get me up and running fairly quickly.

We didn't have a solution like this before that allowed for disaster recovery. Everything was restored from backup, then we had to wait. So, if something went south, then we would need to restore from a backup. I saw the Zerto product was literally one button click, then I can failover to a disaster recovery site and keep going. That was amazing during the initial review of the product. It was just easy.

We started looking at how long it would take to restore from a backup. Rebuilding that infrastructure would take hours, if not days, as opposed to having the ability with Zerto to do a single click, then we are up and running at another site.

It is being used in conjunction with our legacy backup solution.

It was actually fairly easy to set up the solution. Installing it, creating the VPGs, and adding the VMs to it was fairly straightforward.

Working with support on the line, we deployed Zerto in a couple hours.

It is about $1,000 per VM, so it is pricey. However, the cost and time (the manpower cost) that it would take several members of IT to restore a backup and every individual piece of the virtual environment would easily exceed the pricing cost.

If we had to trigger it, downtime would go down to whatever the RPO is at that time. Right now, our RPO average is between four and 10 seconds. This is a big cost saver for us. Anytime certain systems are down within the organization, money is lost.

The only negative part that I have seen so far has been the cost. It is kind of pricey, but you get what you pay for. Zerto is a lot faster than other solutions and you get enhanced performance.

Eventually, we will expand solution use. While there are some competitors in the market, I don't think any of them get to the ease of use and speed that Zerto has. Even Veem has CDP, which is similar, but it is not as fast, user-friendly, or worry-free.

Veeam CDP was still fledgling at the time of our evaluation. It existed, but wasn't that great. It wasn't anywhere near as robust as Zerto. Commvault had something similar as well, but even their solution doesn't do disaster recovery as quickly as Zerto.

It is important that it has both backup and disaster recovery. As I am looking for a backup and recovery solution, I am looking for something that can do everything.

The solution was bought to help with the mitigation of ransomware.

Right now, we are still in a physical data center. We haven't looked at their solution for going to the cloud. That is something which is coming up. Eventually, we will make the switch over. Right now, we are working on a new backup and DR solution. So, that will go hand in hand once we are done with the on-prem.

I would rate Zerto as 10 out of 10 based on the way that the product works.
