User-friendly, cost-effective, and saves a lot of time
Pros and Cons
  • "It is very user-friendly. There is no wondering about what a feature does. It is easy to use."
  • "If they already do not have it, they can have some APIs for the Horizon environment. Instead of having to use some scripts to get around, they can make it a lot more user-friendly for integration."

What is our primary use case?

We use Zerto for server migrations between data centers during the role swap that we do. We use it from a recovery standpoint as well.

We currently do not have disaster recovery to the cloud. We go between our data centers. That is what Zerto helps us accomplish.

How has it helped my organization?

Zerto works very well. We have not had any faults while using it. We are a financial institution, so we have to make sure the systems we have are available with very minimal downtime.

It has helped out a lot in man-hours. It has saved us a lot of overnight work. We can literally change our production servers in a matter of minutes to hours. Rather than having to do this gradually or a couple of weeks in advance and have several teams and business partners involved, we can literally do it live on the same day.

Zerto is probably one of the faster ones in terms of recovery. You can just go into the console, and because it is always replicating over to the other side, it takes minutes.

What is most valuable?

Being able to do our recovery and being able to migrate between data centers during the role swap is valuable just because of the amount of time it takes. It takes 55 hours or so. Right now, we are doing this in a VDI environment. We are going to experiment with it as a proof of concept because we have a thousand machines that we have to move and do all the assignments. Zerto would lessen that down by a few hours, and then we can use some scripts to do everything on the Horizon's side. We have not done it yet, but we are hoping to reduce it down to about 3 hours instead of 55 hours. We will also be able to manage our host better and be in a better recovery state. If the host happens to go down, we can quickly recover.

It is very user-friendly. There is no wondering about what a feature does. It is easy to use.

What needs improvement?

If they already do not have it, they can have some APIs for the Horizon environment. Instead of having to use some scripts to get around, they can make it a lot more user-friendly for integration.

865,384 professionals have used our research since 2012.

For how long have I used the solution?

We have been using Zerto for two years.

What do I think about the stability of the solution?

It has been very stable. We have not had any issues while using it. When we need it to do its job, it is always dependable.

What do I think about the scalability of the solution?

It scales very quickly. We can set up a whole new environment in an hour. We can get the server setup and all the VMs that are required for it to function in an hour or two.

How are customer service and support?

I have not used their support. My peers had to use it. They seem very responsive and knowledgeable. 

Which solution did I use previously and why did I switch?

The other DR tool that I have used is from Symantec. It was an old-school recovery tool. It was back in the day when it took a whole day to get things back up.

How was the initial setup?

It was deployed before I joined the company.

What's my experience with pricing, setup cost, and licensing?

Its price is fair. It is very cost-effective compared to the cost of the labor for your workers and associates. 

Which other solutions did I evaluate?

We selected Zerto over others primarily for the ability to replicate and help with our role swap. It cuts the downtime of the production systems by a large volume. This way, we can meet the deadline and not have that much client impact. In the financial side of banking, you do not want bad performance.

What other advice do I have?

I would rate Zerto a nine out of ten. There is always room for improvement, but it definitely makes your life a lot easier.

Can replicate data rapidly and cost-effectively and has good role-based access controls
Pros and Cons
  • "We can recover both systems on-premises and in the public cloud."
  • "I would like Zerto to enhance the continuous backup aspect."

What is our primary use case?

We use Zerto to replicate our gold systems. Gold systems refer to those that require recovery in a disaster recovery environment within 24 hours, with a maximum allowable data loss of one hour. Therefore, the Recovery Time Objective is 24 hours, and the Recovery Point Objective is one hour.

How has it helped my organization?

I would rate Zerto's ease of use a nine out of ten. The setup of virtual appliances required for data replication is straightforward and effortless. Some of the automation and tooling, such as changing IP addresses or running scripts after a disaster recovery process, is also very user-friendly and simple to configure. 

Zerto's near-synchronous replication is commendable. Usually, the data is only a couple of minutes behind. Hence, we are not employing synchronous replication, but asynchronous replication proves to be sufficient for our needs. It does not appear to deviate too far out of sync or fall too far behind, thereby effectively maintaining up-to-date data. Near synchronous replication holds significant importance as these systems are our critical business assets.

Zerto has helped us improve our organization by enabling disaster recovery both on-premises and in the cloud. We are transitioning towards cloud-based recovery. Our previous solution, before Zerto, only allowed us to replicate data in our on-premises data center, preventing us from migrating to the cloud. Zerto has unblocked us, allowing us to leverage cloud-based recovery now. We were able to realize the benefits within three to four months. The implementation was relatively quick and completed within a couple of months. Everything tested well.

Zerto enables us to perform disaster recovery in the cloud instead of a physical data center, and this is the reason we made the switch to Zerto.

Having the capability to perform disaster recovery in the cloud is of utmost importance to our organization. We are implementing disaster recovery in the cloud to facilitate the shutdown of one of our data centers.

We use Zerto to protect VMs in our environment.

The speed of recovery using Zerto is good. The automation really helps make the recovery quick and easy.

Zerto's overall impact on our recovery time objectives is positive. It is fulfilling exactly what we needed it to do, making it a valuable tool. Additionally, it proves to be fairly cost-effective and easy to set up and use.

Although we have not experienced an actual disaster, Zerto has been instrumental in aiding our disaster recovery testing. Every year, we conduct a DR test to recover systems, conduct assessments, and validate our processes, and for this purpose, we have utilized Zerto. The results have been outstanding, as Zerto has saved us approximately 500 hours of time annually.

Zerto has automated the recovery process by utilizing those playbooks and re-IPing. This has significantly contributed to the reduction of DR testing efforts.

50 percent of the time that Zerto has saved has been allocated to value-added tasks.

What is most valuable?

Zerto can replicate data rapidly and cost-effectively. We can recover both systems on-premises and in the public cloud. We use Microsoft Azure and Amazon Web Services for cloud infrastructure, and Zerto can recover data from both of these platforms. Therefore, it is not limited to a specific cloud provider like the Azure Site Recovery Manager. 

Zerto has good role-based access controls. For cloud recovery, it allows replication over the Internet instead of private networking, which is really nice.

What needs improvement?

I would like Zerto to enhance the continuous backup aspect. If Zerto could replace Veeam from a backup perspective, that would be highly beneficial. Currently, we use Veeam for backup and Zerto for disaster recovery. It would be ideal if we could consolidate both functions into a single product rather than using two separate ones.

For how long have I used the solution?

I have been using Zerto for three years.

What do I think about the stability of the solution?

I would rate Zerto's stability an eight out of ten. We encountered a problem once, but it was resolved.

What do I think about the scalability of the solution?

I would rate Zerto's scalability a nine out of ten.

Which solution did I use previously and why did I switch?

We previously used EMC's Site Recovery Manager and Recover Point. The reason we replaced them is that they utilized sand-based replication, which couldn't be used to replicate data to public clouds. As there are no sands in the public cloud.

Zerto's ease of use, when compared to EMC's Site Recovery Manager and Recover Point, is slightly better. For instance, during the setup process, we didn't require expertise in storage area networks, unlike our previous products. Therefore, it takes fewer skilled resources to set up, configure, and start using Zerto.

How was the initial setup?

The initial setup is straightforward. The deployment took two months. We identified the core machines that we were previously replicating and gradually migrated applications one set at a time. An application could consist of two servers or even five servers. We can perform these migrations in waves.

For the deployment, we had two engineers, one support person, and one architect.

What about the implementation team?

The Zerto team assisted with the implementation.

What was our ROI?

We have seen a return on investment.

What's my experience with pricing, setup cost, and licensing?

Zerto is slightly expensive, but we do see the value in it.

Which other solutions did I evaluate?

We evaluated Veeam, Commvault, and Rubrik. Among them, Zerto had the best feature set for near real-time asynchronous replication.

What other advice do I have?

I rate Zerto a nine out of ten.

The speed of the RPO using Zerto is the same as our previous solution. We haven't lost anything, but we haven't gained much from an RPO perspective either. We had good technology; it was just limited by the cloud because there hasn't been any significant change.

We use Veeam as our backup product to perform some of the point-in-time recoveries.

We have only around six end users who log in to the console in total. Zerto is deployed in our primary data center and is also replicating to a secondary data center where it is deployed.

We have people who monitor whether the synchronization is proceeding well, but there is very little day-to-day overhead in terms of maintenance.

Zerto is a solid industry-recognized quality product.

Which deployment model are you using for this solution?

Hybrid Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Microsoft Azure

It's much faster and cheaper than our previous solution, but it's been unreliable in our environment so far
Pros and Cons
  • "I like the fact that Zerto is target agnostic. It doesn't care what type of storage it writes to. The journaling is also excellent. You can easily and quickly restore to seconds before an event. The immutable data copies feature is one reason we adopted Zerto. That's one of its selling points."
  • "Zerto's near-synchronous replication is excellent when it works. I'm trying to be nice to them because I like the product a lot, but we're having a lot of difficulty with it in our environment."

What is our primary use case?

We use Zerto for disaster recovery, backup, and ransomware protection. The 3-2-1 backup strategy requires us to have two backups of our production data on different media. One copy is on disk and tape backup, and the other is hosted off-site for disaster recovery. With journaling and the persistent backups we take nightly, it almost obviates 3-2-1 because it renders some unnecessary aspects. 

How has it helped my organization?

We adopted Zerto, hoping to speed up our recovery time and improve the overall security of our environment and data. We haven't realized the full benefits, but I expect we will improve our security posture and disaster recovery speed.  

Zerto would enable us to do cloud-based DR instead of a physical data center, but we are based in a very rural area of Colorado. We're deep in the mountains, so leveraging the cloud is challenging. We have little-to-no cloud presence, but Zerto can enable us to move our disaster recovery into the cloud because it is agnostic to the backup target. That could easily be a cloud provider. We only need redundant and reliable circuits to the cloud.

The impact on our RTO is theoretical because we haven't had to do any critical recovery. Based on our testing, it should significantly improve our RTO because the backup technology is more efficient than our previous solution. RTO is one of Zerto's strengths. Zerto enabled us to test our DR plan. Our disaster recovery needed a lot of help when I joined two years ago, and it's one of the projects I have been working on. Zerto is central to our DR plan. It's the primary cog in that machine. Zerto cut our hardware and maintenance costs by about 50 percent.

What is most valuable?

I like the fact that Zerto is target agnostic. It doesn't care what type of storage it writes to. The journaling is also excellent. You can easily and quickly restore to seconds before an event. The immutable data copies feature is one reason we adopted Zerto. That's one of its selling points.

Zerto is easy enough to use. It's as usable as any other backup solution. We're accustomed to dealing with complex options and everything available to us in the suite. 

What needs improvement?

I tried a file-level recovery, which should work on any server. However, the server we need to protect the most is the one giving us problems. We couldn't do a file recovery without restoring the entire server to a recovery partition that isn't part of the production and pulling the files off it that way.

Zerto's near-synchronous replication is excellent when it works. I'm trying to be nice to them because I like the product a lot, but we're having a lot of difficulty with it in our environment.

There is a disconnect between the sales pitch and what we can do with Zerto in practice. We've been trying to reconcile that for most of the year. There should be more continuity between sales and implementation to ensure the solution is implemented how our presales engineer pitched it to us. 

They need to have some accountability. Maybe the implementation engineer should be on the line so that they know what is presented and agreed upon regarding the implementation in our environment. The implementation should have been precisely what we were expecting. 

I was part of the pre-purchase team as the information security manager. I handed it off to my infrastructure team to implement, and they practically had to start from scratch. Zerto handed it off to their professional services to implement, and I assigned the job to my team. 

There were a lot of questions and things Zerto couldn't do on its end. HP purchased Zerto as we were engaging with them. I don't know if that was related to our frustrations, but I know that acquisitions can make a product messy for a bit. I don't want to blast Zerto. It's an excellent product, and I would love it if it could work as advertised. I've seen it do some of that for us. We've had a rough start, and we're still trying to find that sweet spot.

For how long have I used the solution?

I have used Zerto for nearly a year.

What do I think about the stability of the solution?

Zerto isn't reliable in our current environment. We keep running into these weird little issues. At one point, we didn't have complete backups on a couple of key servers for more than a week because of this issue. If we had gone down that week, it would have been ugly.

What do I think about the scalability of the solution?

Zerto seems pretty scalable. We bought something that we can add on to and increase the horsepower. Every change we've made has been smooth.

How are customer service and support?

Their support and account management teams have been pretty amazing. They are bending over backward to make it right with us, so they deserve a lot of credit for that.

Which solution did I use previously and why did I switch?

We used Avamar. Zerto's recovery is faster, and it's a little more straightforward. Zerto is an improvement in RPO, RTO, ransomware protection, immutability, and cost. Avamar costs nearly 75 percent more. There's no significant difference in ease of use. 

How was the initial setup?

I wasn't involved in the initial setup. After the deployment, there is a lot of maintenance. It throws out lots of errors, and we sometimes need to rebuild some of its components. Our backup guy is a little frustrated at times. 

What was our ROI?

We haven't seen a return aside from saving money on the annual license because we've had to invest so much time into getting it to work.

What's my experience with pricing, setup cost, and licensing?

Zerto's price seems fair. It's competitive. 

Which other solutions did I evaluate?

Dell Avamar for Data Domain offers functionality similar to Zerto, but we weren't taking advantage of it. We also looked at Rubrik, but it's a cloud-based solution, and it's a little costly. We're not in a position to leverage cloud solutions at this time. Avamar costs too much to get the same features. Doing a rip and replace was more economical than keeping the hardware in place and adding the functionality.

What other advice do I have?

I rate Zerto a six out of ten. I only give it a low rating because of the issues we've faced lately in our environment. If we didn't have those issues, I'd probably give it an eight.

If you plan to implement Zerto, I suggest double-checking everything. Confirm the configurations and ensure your backup targets are sufficiently sized. You must know what you want from the product, and that requires guidance from the sales engineer. Make sure the plan is solidified and you have a document that spells the whole thing out.

Which deployment model are you using for this solution?

The solution can achieve very low recovery point objectives due to its efficient use of resources and compression techniques
Pros and Cons
  • "I give Zerto's stability a nine out of ten."
  • "Zerto's price has room for improvement."

What is our primary use case?

Zerto is primarily used for disaster recovery. In rare cases, it is also used for backup, but only for long-term storage.

We deployed our on-premises infrastructure in two data centers in Russia located in two cities, and multiple regions with combined infrastructure. We also had two data centers in Europe.

How has it helped my organization?

Zerto is extremely easy to use. When I started to pilot the product in 2016, I was able to deploy all required components in one or two hours without any help from Zerto engineers. I only used the provided documentation and user interface. In the years since my engineers have also had no issues with the implementation or configuration of the product. Zerto's ease of use is one of its best features.

To ensure good synchronization and replication of changes in a timely manner, we need to have a very good storage subsystem. In our case, we replaced our old storage subsystem with a new one that is based on full flash storage. After that, Zerto started to replicate changes at lightning speed. Many companies experience issues with Zerto if they do not have full flash storage. When full flash storage is implemented, Zerto is the best replication solution because it is highly dependent on the latency of the storage. Therefore, any kind of storage that is not based on full flashes, such as hybrid storage that combines flash and disks, is not a good foundation for Zerto implementation.

Prior to implementing Zerto, our disaster recovery tests had a 70 percent success rate. After implementing Zerto, all DR tests were 100 percent successful. This represents a significant improvement in our DR capabilities.

We used Zerto to replicate our virtual machines from our primary data center to our disaster recovery data center in another city over a single connection.

Zerto can achieve very low recovery point objectives due to its efficient use of resources and compression techniques. However, our company has different RPO requirements for different-sized companies. Since our company is small, our standard RPO is four hours. Zerto exceeded this requirement by achieving a typical RPO of about 15 seconds.

Zerto is a very easy and fast tool to use. However, it is important to note that Zerto requires some time to accept changes after migration. This means that if we do not finish testing within the required time frame, we may run into issues with storage space, as Zerto will continue to collect logs and other data. If the testing period is short and we are comfortable switching between data centers frequently, then we should have a very good experience with Zerto. Compared to VMware SRM, Zerto is much more reliable. I have never had any issues switching between production and the DR data center with Zerto, while I have had to start DR exercises from scratch multiple times with VMware SRM.

We always define and perform the required RTO values in our company. RTO is the time required to recover from a switch. It is about how long it will take IT staff to restore the environment. With Zerto, we can now do this in hours, typically one or two hours, for all switching activities. We have 70 virtual machines configured in Zerto, so it takes about one hour to switch all of them. This is four times faster than our previous solutions, such as VMware SRM or storage-based replication.

Zerto has saved us time in data recovery situations due to ransomware or other causes. It is very easy to use, so we do not need to spend extra time training engineers on how to use it. All of our engineers were able to start using Zerto immediately. Zerto is also very fast at replicating data. For example, when we set up a new replication, the initial replication was completed very quickly. Another advantage of Zerto is that it does not require additional steps to change the size of virtual disks. With our previous solution, VMware SRM, engineers had to perform additional manipulations in VMware when changing the size of virtual disks. This was a complicated process, but it is not necessary with Zerto. Overall, Zerto is a very user-friendly and efficient data protection solution. It has saved us time and money, and it has made our data recovery process much easier.

Zerto has saved us around 50 percent of our time.

What is most valuable?

The most important thing to me is Zerto's ability to deliver continuous protection for all data without any issues or incidents. Zerto is a rock-solid product in terms of protection. We migrated to Zerto from VMware SRM because we had a lot of issues with VMware SRM, including the loss of one server.

What needs improvement?

Zerto's price has room for improvement.

For how long have I used the solution?

I have used Zerto for six years. 

What do I think about the stability of the solution?

I give Zerto's stability a nine out of ten.

What do I think about the scalability of the solution?

Globally we have around 200 engineers that use Zerto.

How are customer service and support?

Zerto's technical support is excellent. When we first started using Zerto, we had Russian technical support to help us with some complex tasks, such as configuring unique virtual machines. Our engineers had no communication issues with the support team. Later, when we were in a stable period, global technical support was also very helpful. I cannot recall a time when technical support was unable to help us. Overall, I give Zerto's technical support five stars.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

For many years, the company globally used a variety of different solutions for data protection and disaster recovery. These included storage-based replication solutions based on IBM and EMC storage, as well as special appliances from Dell EMC. For smaller companies, VMware SRM or VMware replication without SRM was used, with manual configuration of replication. In order to simplify and unify its data protection and disaster recovery strategy, the company decided to adopt Zerto. Zerto was initially implemented in a small region, the Middle East/Asia. After a couple of successful migrations of data centers in this region and a parallel unsuccessful DR exercise in EMEA, the company selected to use Zerto globally. Following this, smaller companies in Russia started to receive a recommendation to implement Zerto instead of any existing solutions. Zerto has been a success for the company, providing a unified and simplified data protection and disaster recovery solution that has improved the company's overall resilience.

How was the initial setup?

We used one internal engineer to perform the initial setup on two data centers in two days. In general, this involved installing two virtual machines with Zerto Virtual Manager on each data center, creating the corresponding network access rules, and then deploying Zerto replication agents to all virtualization hosts. The last activity was automated, so it took about one hour to deploy Zerto for all virtualization hosts. The replication took one week.

What about the implementation team?

The implementation was completed in-house.

What's my experience with pricing, setup cost, and licensing?

Zerto is a premium disaster recovery solution. It is not the cheapest option on the market, but it offers a number of features that make it a good value for businesses that need a comprehensive disaster recovery plan.

What other advice do I have?

I give Zerto a ten out of ten. Based on my experience with different replication solutions, Zerto is the best one I have used. I am very disappointed that my current company decided to stop using it due to existing standards. Zerto is not cheap, but it is very stable, available, fast, and easy to use.

The most time-consuming part of a disaster recovery test is the testing of small and medium-sized enterprises, business users, and other stakeholders. IT-led environment restoration activities typically take up about 30 percent of the overall DR process. Zerto can reduce this time by 50 percent. Overall, this is not a significant impact, and Zerto is a very stable and reliable solution.

Zerto has not reduced the number of employees involved in data recovery situations. This is because we have a small team, and we always use engineers to perform disaster recovery activities related to storage and virtualization infrastructure. As a result, we have not had to reduce the number of staff members used for these activities.

Zerto did not replace all of our legacy backup solutions. Our legacy backup solutions were dependent on IBM Power servers, which required corresponding backup agents. Zerto is not compatible with these agents, so we use a separate backup solution for these servers. This separate solution is still in use.

We have two data centers, each with its own equipment, servers, storage, network equipment, and so on. In each data center, we deployed two separate VMware vCenter server infrastructures connected using an L2 line. There was no L3 connection between the data centers. This created a flat L2 network with two data centers and two vCenters on each data center. After that, we deployed two VM servers configured for replication. This allowed us to have a highly available and resilient infrastructure in the event of a failure at one of the data centers.

Regarding Zerto's maintenance, we configured some monitoring for related Zerto services. However, we do not have any daily routine procedures to manually check Zerto to ensure that everything is working properly. Instead, our engineers spend one hour per week reviewing monitoring items and other metrics to ensure that Zerto is operating as expected. From my perspective, Zerto is a self-operating system that requires very little manual intervention.

Zerto is very easy to pilot. I recommend that any customer pilot Zerto before making a decision on whether or not it is the right solution for them. Zerto is a self-selling product. When I piloted it in 2016, I was able to install it in hours and start using it immediately without any help. I believe that a pilot is the best way to see how easy and beneficial Zerto can be.

The level of disaster recovery RPO that we can now offer has been a game-changer
Pros and Cons
  • "The near-synchronous replication is key. That has allowed us to provide the low RPOs that we promise. For key systems, that has been the deciding factor."
  • "I would like to see improvement on the Zerto Virtual Replication appliances, so that they are a little bit more streamlined as opposed to now where they just span multiple ZVR appliances like there were gremlins... as this thing grows it just spawns unlimited numbers of additional ZVR appliances and you end up with a bunch so that you can't really tell which is which."

What is our primary use case?

Zerto is used as our go-to disaster recovery failover software for the replication of key systems from our main office to our main data center. We primarily use it to protect VMs.

How has it helped my organization?

Being able to offer the level of disaster recovery RPO that we do has been a game-changer. Offering that level of RPO would have taken other methods to accomplish, but this has been straightforward.

It has been compatible with our VMware environments as time has progressed. We started using this in 2013. To make it easy and even more seamless, they spanned a Layer 2 subnet from one site to another using networking strategies. That way, when we fail over a VM or an asset, it does not change IPs at all. It has definitely given us a level of recovery that we would not have been able to accomplish as easily otherwise.

Recovery with Zerto is faster because, in the past, I believe our organization implemented asynchronous replication and used replication methods that were specific for storage. Having synchronous replication and an RPO that is essentially nothing, between sites, has definitely increased our response time. It allows us to immediately fail over seamlessly. It has also reduced RTOs throughout, since the recovery point objective in general is just a second. The smaller our RPO gap, the faster the RTOs we get.

In terms of downtime, there was a particular situation where we had an unexpected double outage of our WAN link. Unbeknownst to us, both of the fiber runs, although they were from the same company, ran through the same place, along the same train tracks where there was maintenance going. We were able immediately to fail over to our secondary site and keep downtime to zero.

That was an outage that I now know, in hindsight, lasted a couple of hours and it was during the peak closing of the US market for trading. It would have cost us millions. It would've been bad if something had gone wrong, since we needed to trade "now, now, now," but would not have been available. Thankfully we were able to trade.

Another benefit is that it allows for automated testing and non-impactful testing with the ability to spawn VMs in a test. We can perform any type of DR and integrity testing at will without impacting our production. I can't really quantify it but I know that DR tests definitely move a lot quicker now. Normally, DR testing would happen over a weekend. And it used to be the case that we would fail over everything immediately. We still have tests where we do live failovers with Zerto, because they really want to say we have done them. But we have averted investing time in monthly and quarterly tests over a weekend because we can present the automated testing that happens by Zerto with that test network. Without that, we would have to do monthly live testing, so it saves us time.

What is most valuable?

The most valuable feature is its ability to do failovers from one site to another.

It's also very intuitive, simple, and very straightforward. Its layout doesn't seem very complicated. It shows its features upfront. When I first started using it in 2016, I had not heard about the product, but coming to this company and having to take over managing it was not challenging at all. I was able to intuitively start using it. I have not had any issues with the interface. It's a clean interface and that has allowed me to intuitively use and configure it.

The near-synchronous replication is key. That has allowed us to provide the low RPOs that we promise. For key systems, that has been the deciding factor. The other option would have been establishing VMware's native HA approach, where you have to spawn new VMs. It's not as transparent as Zerto, it's more under the woodwork. Zerto's ability to offer that level of synchronicity and immediateness has enabled us to offer that level of SLA for our processes in case of a disaster.

What needs improvement?

Recently, I started to try to deploy vVols instead of VMFS volumes in my VMware environment and I did encounter an incompatibility. It seems that for Zerto volumes to be protected, there's some sort of limitation with drives having to be either thick-provisioned or thin-provisioned, I forget which. But there's some sort of inherent limitation that causes an incompatibility with vVols and VMware. That has to be overcome somehow. It has to be flexible enough to be able to do its thing.

And for an additional feature, and I'm not sure if this is already in the works, I would like to see improvement on the Zerto Virtual Replication appliances, so that they are a little bit more streamlined as opposed to now where they just span multiple ZVR appliances like there were gremlins. We have our three main ZVR appliances, each one of them associated with one of the hosts, but as this thing grows it just spawns unlimited numbers of additional ZVR appliances and you end up with a bunch so that you can't really tell which is which. Better management of those ZVR appliances would help, if you have to vMotion them off of something.

If you want to migrate a ZVR appliance from one storage to another, you can't really tell what's what and there are multiple pieces related to this ZVR appliance. I would like to see that cleaned up a little bit with better management features for ZVR appliance maintenance overall.

For how long have I used the solution?

I've been with the company since May of 2016, so I've been using Zerto for that long—going on seven years. Through the years, I have become a Zerto-Certified administrator because Zerto offers a free course on it.

What do I think about the stability of the solution?

It's very stable and very hands-off. I have so many other things to do and the last thing I need to be doing is babysitting Zerto, and that's not the case. Thankfully, it's one of those solutions that you set and forget. You pop in every once in a while and make sure the VPGs are still green and thinking. 

The only thing that has happened over the years is that the data store that this thing was on might have run out of space, but that was for other reasons. As long as you keep an eye on it, it will probably always be green and you'll never have to do anything.

How are customer service and support?

I've been able to engage with their support many times over the years and I have not had bad experiences with them. They've always been very efficient and prompt in taking me out of very sticky situations.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

We already have solutions in place for backup, such as Rubric. We used to be a Veeam shop.

How was the initial setup?

I wasn't involved in the initial setup.

We have two environments, one in our main office and the other in a data center. We have virtual protection groups that protect VMs in the main office and we are able to move them from failover to the data center as a DR strategy. That will change in the future when we move all assets that currently exist in our practice office into the data center as its native location. For now, it's office and data center, but in the future it will be data center and data center.

Our Zerto environment is VMware vSphere 7, and ESXi 7. It's mostly Windows VMs but there are some Linux VMs in there. It's a mixture of thick and thin-provisioned drives, all on VMFS data stores. Those are VMs that it protects and that it is able to move from one place to another.

As for maintenance, Zerto is really hands-off. It's just the usual software updates and that's about it. 

I believe the next step is that the recovery ZVMs (Zerto Virtual Managers) will turn into appliances, so they will be full Linux appliances. That will be great because we won't have to patch the Windows box underneath. Once that migration happens, it'll be even easier to manage. The only other thing that I have to do every once in a while is when we have another VM to protect. I edit the VPG and keep moving.

What was our ROI?

We have seen ROI due to the lack of losses from downtime that has been avoided.

What's my experience with pricing, setup cost, and licensing?

The pricing seems reasonable. It's still within what we consider to be value-add. Currently, we're running 50 licenses. We're probably going to downsize because there have been organizational changes in our environment and we don't protect as many VMs as we used to.

Which other solutions did I evaluate?

We have not looked to change over since I got here because Zerto has been that good.

What other advice do I have?

We don't really leverage the restore point backup capabilities of Zerto, although we do, in our virtual protection groups, configure it to have at least two hours' worth of restore points since the last RPO. We also haven't ventured toward DR in the cloud, although there will be initiatives in the future, but it's just something we have not done yet. At least for the assets we're covering with Zerto right now, we've limited ourselves to being able to pivot between data centers.

Currently, we are using it to provide DR coverage for key assets, but I am also going to use it to move all these assets from the practice office in downtown Chicago to the data center, which will be its permanent location. I am going to leverage Zerto's move capabilities to relocate those VMs, Windows Servers, and Linux boxes to the data center permanently. And then I'll establish a recovery relationship between data centers.

For the cost of the product, its value-add, and the return on investment, which is twofold, you should definitely consider Zerto. The hands-off approach and stability of the product alone will give additional dividends. Invest in the solution. It's pretty great.

Zerto is a 10 out of 10 for me. It's one of the easiest pieces of software that I have to manage and one of the most reliable over the years.

The overall effect on our RPOs has been fantastic
Pros and Cons
  • "The most valuable feature is the disaster recovery capabilities. The fact that we can have a clinic across the country backup in as little as 45 minutes is incredible."
  • "As one who is implementing it, my biggest gripe is the ticketing system. Zerto has since upgraded that, so right now, I have no complaints about it."

What is our primary use case?

Our primary use case is for backup and disaster recovery. 

What is most valuable?

The most valuable feature is the disaster recovery capabilities. The fact that we can have a clinic across the country backup in as little as 45 minutes is incredible. 

Zerto has enabled us to do disaster recovery in the cloud. This ability is very important because we have over 419 hospitals across the country and being able to quickly get a hospital up in Colorado while I'm in Alabama is impressive. The speed is impressive and it's easy to get it back up.

We use Zerto to protect VMs in our environment. Zerto's overall effect on our RPOs has been fantastic. Coming from our C-suite level and getting reports of how long hospitals are up versus if we do have disaster recovery, the amount of time to recover using Zerto is fantastic. We can have them back up in as little as 45 minutes. I don't have to hear all the bad sides of it, they're very happy when the hospital's back up and making money. 

The other company we used before was Commvault, and we had had multiple issues with them with fragmented backups. Some backups weren't taking properly, and we did have a DR situation with them, and they were not able to recover all the data. That was our big push to find something else, and that's where we found Zerto. 

Zerto's ease of use compared to other solutions is a ten out of ten. 

What needs improvement?

As one who is implementing it, my biggest gripe is the ticketing system. Zerto has since upgraded that, so right now, I have no complaints about it.

For how long have I used the solution?

I have been using Zerto for around one year but my company has been using it for about two. 

What do I think about the stability of the solution?

The stability is a ten out of ten, we haven't had the issues with them like we did with Commvault. I have no complaints.

What do I think about the scalability of the solution?

Scalability is seamless. We're able to add another server and within the hour build on top of that. 

If we're ever out of licenses, I could just send an email out and say that we need to add some more, and it's done. 

Our environment is large. We have 419 hospitals across the country. 

How are customer service and support?

Their support is a ten out of ten. I have not had any issues with them. It's been fantastic every time I've had to deal with them. They've resolved all of my issues. 

How would you rate customer service and support?

Positive

How was the initial setup?

The deployment was easy and seamless. We put in a ticket. They get our new servers added and within an hour we have new deployed servers on the solution.

What was our ROI?

We see ROI in the uptime of hospitals that had a disaster recovery scenario and how quickly they're back up and making money at those hospitals.

What other advice do I have?

I would rate Zerto a ten out of ten.

Ensures that we have the most up-to-date information in the case a disaster occurs
Pros and Cons
  • "My organization has experienced the benefits of using the tool, which include the ability to test our disaster recovery quickly."

    What is our primary use case?

    The primary use case for Zerto in my company is to manage disaster recovery.

    How has it helped my organization?

    My organization has experienced the benefits of using the tool, which include the ability to test our disaster recovery quickly.

    What is most valuable?

    The most valuable feature of the solution is the constant synchronization, ensuring that we have the most up-to-date information should a disaster occur and we need to handle failovers.

    Zerto's near-synchronous replication is why we first acquired the product.

    Zerto's overall effect on our RPOs is such that it improves them significantly, and it is the reason why we purchased the product. Rather than having to recover from backup, which is time-consuming, it is available instantly.

    If I compare the speed of recovery with Zerto versus the speed of recovery with other disaster recovery solutions, Zerto is at least five times faster than other products.

    What needs improvement?

    It turns out that my organization has not been using all the capabilities of Zerto and we just found from the session, HPE Discover'24, that the things we were looking for already existed within Zerto. I don't have anything to ask for improvement in Zerto.

    I don't want any additional features in the product as I would be busy employing the functionalities I recently found out are available in the solution.

    For how long have I used the solution?

    I have been using Zerto for seven years.

    What do I think about the stability of the solution?

    The tool is very stable.

    What do I think about the scalability of the solution?

    The scalability is fine for our company. We are a relatively small organization, but it has done everything we needed.

    How are customer service and support?

    The solution's technical support has been solid and very good, and we hope it stays that way under HPE.

    Which solution did I use previously and why did I switch?

    In our company, we would recover from our backup software, so things depended on whatever backup tool was used at the time.

    How was the initial setup?

    When it comes to the product's initial setup phase, Zerto's support has been very strong and relatively straightforward.

    What was our ROI?

    I have experienced a return on investment from the use of Zerto. The exercises associated with disaster recovery are faster and we are able to save time now in our company.

    What's my experience with pricing, setup cost, and licensing?

    Fortunately, the tool's pricing and licensing are not a concern for me at the moment. Other teams handle it.

    Which other solutions did I evaluate?

    The evaluation of other solutions against Zerto was pretty quick. In our company, after we saw a Zerto in use, we couldn't find anything else like it in the market.

    What other advice do I have?

    I have used Zerto to protect VMs in our company's environment.

    Considering that there is always someplace to go from where our company is currently, I rate the tool a nine out of ten.

    Has a fast recovery time and good near-synchronous replication
    Pros and Cons
    • "Speed of recovery has been very effective in getting our information back as fast as we're able to get it. The daily backup solution that we use alternatively only allows a single backup versus having continuous backup replication with Zerto, it's a no-brainer."
    • "I would like to have more granular notifications for jobs and workloads within the applying case application."

    What is our primary use case?

    We've used Zerto for file recovery and entire VM recovery.

    What is most valuable?

    Having a fast recovery time for both of our use cases is invaluable to the business. 

    The ability to form our backups automatically during the day has saved us, more than a few times. 

    My impression of Zerto’s near-synchronous replication is very positive. It gets the job done. 

    Near-synchronous replication is very important for our organization who use a lot of different versions of files across environments and database changes. It's what we do every day and having the functionality of near-instant recovery on entire virtual machines and files is a blessing. 

    We use Zerto to protect our VMs in our environment. We do daily backups with a different backup management software and having the ability to recover data in under ten seconds has been helpful.

    Speed of recovery has been very effective in getting our information back as fast as we're able to get it. The daily backup solution that we use alternatively only allows a single backup versus having continuous backup replication with Zerto, it's a no-brainer.

    What needs improvement?

    I would like to have more granular notifications for jobs and workloads within the applying case application.

    For how long have I used the solution?

    We have been using Zerto for around sixteen months. 

    What do I think about the stability of the solution?

    It's pretty stable. The company itself has been around long enough to know they're not going anywhere. The number of clients that use them on a day-to-day basis speaks for itself. 

    What do I think about the scalability of the solution?

    For our environment, scalability does a great job with how it is. It can handle scaling. 

    How are customer service and support?

    Zerto technical support is some of the best around. I know when I reach out to them over the phone or via email, they are there quickly and offer great support. 

    I would rate them a ten out of ten. Every time I have to call them, they get something ready, very fast, and our issues are resolved quickly.

    How would you rate customer service and support?

    Positive

    Which solution did I use previously and why did I switch?

    We still use Veeam.

    We chose Zerto because when we started our path with GreenLake, we began looking into other backup utilities and Zerto was highly recommended. After we saw a product demo, we were sold. The demo sold itself very well.

    Once the VPG is configured, the automation for backups happens on its own. There's nothing else to do. You can monitor but until you need to recover the files, there's nothing else to do. Zerto is very simple. We enjoy using the product. 

    The main difference between Veeam and Zerto is that with Zerto, we can get our near-instant recovery window to pull entire virtual machines back from the brink of failure. We might be able to implement more recovery windows for Veeam but from a data storage perspective, Zerto does a great job with deduplication.

    How was the initial setup?

    We had a third party enable our Zerto configurations. They did a great job. The same VPGs are still running today. 

    What about the implementation team?

    We used an integrator for the setup. We had a good setup. They walked us through any issues we had after the setup. 

    What other advice do I have?

    I would rate Zerto a nine out of ten. There is a network issue that my team is still trying to figure out. Once we take care of it, it'll be a perfect ten. 

    Zerto should be our primary backup solution but until we can get the network issue resolved, it is relegated as a secondary source. It still does its job. We've used it multiple times for specific cases, and it's always passed with flying colors.
