HPE Zerto Software Reviews

We do many data-related activities for various government ministries in India. We use Zerto to back up and recover data in many training and capacity-building activities.

We implemented Zerto to address challenges with data centralization in our complex platform environment. Previously, pulling data from a central source was impossible due to the need to feed it into an internal location before deployment. This limitation hindered customization and integration efforts. Additionally, integrating our primary data source, previously used with IBM, into the new platform proved difficult due to compatibility issues. Zerto's capabilities were seen as a potential solution to these problems.

The remarkable benefits of Zerto have yet to manifest fully. The software operates efficiently without significant bugs or issues, and Zerto's customer support has been responsive. While real-time reporting is a standout feature compared to other trial products, its impact on our ongoing projects remains to be determined. A full assessment of Zerto's potential will require an additional six months.

Zerto has significantly improved our Recovery Time Objective, particularly regarding project timelines. The expedited turnaround during critical project phases has been instrumental in streamlining our processes. By accelerating these stages, we've reduced the need for additional developer resources and eliminated time-consuming tasks associated with establishing essential parameters and metrics. As a result, projects that previously took six months can now be completed in as little as four. This accelerated timeline has enhanced profitability and optimized resource allocation, allowing us to maximize project revenue.

Zerto has significantly reduced our disaster recovery testing efforts. By consolidating software and streamlining processes, we've dramatically decreased the required manpower. Multiple teams efficiently utilize a single platform, eliminating the need for disparate services and reducing costs. This centralized approach has markedly decreased the time and resources invested in disaster recovery testing and pre-testing activities.

Zerto's greatest strength is its speed. We never encountered lag or interruptions, even when working remotely from home or other locations with potentially limited internet bandwidth. The software's streaming performance was exceptional, without buffering or connectivity issues. This was a primary factor in our decision, as Zerto emphasized its ability to operate effectively on lower bandwidth connections during the initial demo. Deploying the software in any remote location is straightforward and hassle-free.

The primary concern expressed by all server users is the lack of robust integration features. While Zerto offers some integration capabilities, the smooth and efficient data flow between portals remains a significant challenge. The support and technical teams know this issue and actively seek user feedback, but progress has been slow. The current process, involving multiple platforms and a database management system bottleneck, is time-consuming and inefficient. Additionally, while reporting and dashboard features exist, real-time reporting and mobile functionality require improvement. The user interface could be more intuitive and user-friendly. Customization, a critical requirement for government clients, is another concern. Implementing requested changes is often time-consuming and expensive, hindering adaptability. Addressing these integration, reporting, user experience, and customization issues is essential for improving customer satisfaction and retention.

Currently, Zerto only offers an annual subscription, but it would be beneficial to provide quarterly and semi-annual subscriptions to help retain clients.

I have been using Zerto for one year.

I have not encountered any performance issues, such as lagging or crashing. The system operates efficiently and reliably under various conditions, even with significantly lower bandwidth. Zerto has consistently demonstrated stability and high speed, ensuring uninterrupted application performance.

Approximately 50 to 60 individuals within our ecosystem utilize Zerto directly or indirectly. Given its operational efficiency, which I estimate to be between 95 percent, I confidently assert its scalability. While we haven't encountered a scenario within our ecosystem that necessitates testing its scalability limits, its exceptional performance thus far strongly suggests its capacity to handle increased demands.

Zerto uses a ticketing system and offers support through a help desk accessible via chat or phone. A dedicated technical team is assigned to address customer issues, which are typically resolved within 24 hours. We have not experienced any significant delays in issue resolution.

Positive

We find the Zerto pricing fits our budget.

I would rate Zerto nine out of ten.

Maintenance is required quarterly. The Zerto technical and business teams collaborate with us on the backend to remove all the repeated queries that make the system sluggish. This service is charged additionally.

I strongly recommend that anyone considering purchasing Zerto begin with the 30-day trial, which can be extended to 60 days. This ample timeframe allows a thorough evaluation of all features and functionalities. Understanding Zerto's customization and integration capabilities to align with specific business needs is crucial. Had I followed this approach and shared my feedback earlier, the outcome might have been different. Therefore, it's essential to fully explore the trial version before committing to an annual subscription. Close collaboration with the Zerto technical team is vital to ensure successful implementation. While sales teams often present an optimistic view, real-world experiences from existing users provide the most valuable insights. I encourage potential customers to connect with other Zerto users through industry networks to gather honest feedback before purchasing.

Our primary use case is to continuously replicate our VMs to our DR site. Having the ability to recover them at almost any point in time, mostly back thirty days, is the main purpose of Zerto. 

We didn't previously have a continuous replication tool and now we have the ability to recover to any number of points in time. That's really beneficial to us. It cuts down our recovery time. 

The most valuable feature is how quickly it powers down the original source VMs and the speed at which it powers up the new VMs. The amount of time it takes to put up the operating system is valuable. The speed is what I like the best. 

The near-synchronous replication is awesome. When you get hit by a cyberattack, you never know where the clean VM resides, and at what point in time it actually exists. Having the ability to find the point in time when we are clean is a good thing.

We are going from a physical data center to a physical data center at the moment.

We use Zerto to protect VMs in our environment. It increased our ability to restore at a point in time. We didn't have it before, and now we have it.

Compared to other tools, Zerto is a lot faster. There are tools with your primary block storage backup, but they're just not as fast.

I'm having a problem with CentOS 7 and with VMs with multiple network adapters. Zerto recognizes those multiple network adapters on CentOS 7 vm but it will not give me the option to specify a failover IP, for that particular VM. Something's not working right, but Zerto is going to follow up. 

Zerto has been in production for three months. 

It seems stable so far. 

The scalability seems pretty easy. 

Customer service is really good. Technical technical support is lacking. At least from who I've been talking to. Maybe my case has not gotten bumped up to the higher level technicians. Customer support is great, and they're really responsive but their technical knowledge is just not quite there.

Zerto's documentation is outdated. I'm finding it hard to find documents related to my questions. Their documentation is bad.

Neutral

The initial setup was very easy. We needed a little help with the initial configuration, but it was pretty straightforward. 

We worked with Eagle Technologies for the deployment. We loved them.

I wasn't involved in negotiating any pricing. It evidently worked into our budget.

We also looked at Cohesity and Rubrik. I don't know that there's anything like Zerto. We went with Zerto because our third-party vendor recommended it. We also did a proof of concept two years ago. We liked what we saw with Zerto so we went with it. 

Everybody taunts their one pane of glass but Zerto is simple to use. I really like the GUI, the interface is not too busy. 

I would rate Zerto a nine out of ten. We don't have a test network setup. I know with Zerto, you can simulate a recovery. 

Zerto would be a perfect ten if the documentation was easier and if level 1 support would be more knowledgeable.

A lot of use cases involve how we effectively manage our DR and make sure there's not a lot of manual effort. On the business side, we proved the solution worked and showed the analytics on the DR report afterward. Those are the requirements.

At one of the banks I worked for, we used it for our merger and acquisition to replicate a legacy application that was no longer supported. Rather than try to rebuild it, which would have taken days or weeks, we could use Zerto to replicate it to our data center and join it to our domain. That was one of the biggest use cases we have had. 

Another use case is for disaster recovery as a service (DRaaS) and to migrate service to a public cloud.

Zerto's near-synchronous replication is great. Not a lot of solutions can do that, and most organizations don't know that Zerto can do it. Once you have that near-sync capability, you can see how much more you can recover and be more resilient. 

At the end of the day, we're trying to protect our data and not put the company at risk, whether it's from a cyber attack or just any sort of DLP data loss. 

In financial services, data is paramount: protecting it, making sure you don't lose it, and integrating it. Having that near-sync ability is useful to any organization.

Zerto helps protect VMs in our environment. It really increased how many points in time we can recover, and not only the time to do it but where we want to do it too. 

Generally, we choose a point in time because they're simulated tests and controlled. In the event of a true disaster, I'm sure I'd utilize one of the closer points to have more recent data, but it's good to have that option. Luckily, I haven't had to use that option.

It's night and day. With other solutions, you're locked into specific RPOs and RTOs based on how that solution works. Zerto gives us the flexibility to choose which we want to use and recover effectively.

The main valuable features are the fast RPO and RTOs we could achieve and the analytics behind that. 

In my role these days, I have to make sure I can prove to the executive team as well as the business lines why we chose this solution and how it can help us.

One of the projects we're working on is DRaaS service. Once that's implemented, we'll test that solution. The whole premise of using Zerto is to replicate one-to-many and then test that scenario.

Zerto should continue adding new features. When I used it at the other bank, it wasn't good with replicating VDIs and automation. They've made a little more advancements in automation and scripting since then. 

At one point, it was custom, requiring professional services. Now, Zerto has more built into its engine that will help with the failover of virtual desktops.

I was an early adopter. I worked for a managed service provider in New York City back in 2009 and was introduced to Zerto near the end of 2010, early 2011. That's when we started implementing it for our clients. I've been bringing Zerto wherever I go ever since.

Stability is great. Sometimes you have network blips, and you can be out of sync, but it'll catch up eventually. There are very minor issues, if any.

It is very scalable. For example, there's a tertiary site that we're building for the DRaaS service. 

We just go to initiate the one-to-many and replicate up there. It's easy.

The customer service and support are responsive initially, and then they help you solve your problem. There was only one time with the custom scripting for the VDI that they wouldn't help because it was custom, and they wanted more money for that. They incorporated that into their solution a few years later.

Positive

In the past, I have used a different solution. I've worked with SRM, Double-Take (which is terrible), and BMC Recovery Point. Ever since I got hooked on Zerto around 2011, it's been pretty much Zerto.

The installation itself is very easy. Any problems I've run into, either when I was managing it or doing the installation myself, support has helped every step of the way and has been very easy to work with.

It's on Expedient's cloud, which might be AWS. I'm not sure. I just know we're doing it through a third party.

A lot of the ROI is with engineering hours. If it took eight hours of overtime to pay one or two engineers to do a DR test, now we can do it in one hour. 

We can factor in how many DR tests you do and calculate the cost savings. That alone is a good ROI.

The pricing is pretty fair. It increases with the number of VMs you have. When we had about 600 VMs at my last bank, we did an enterprise licensing agreement that helped cut down the cost. It required signing on long-term, but it was the most effective.

I would rate it a ten out of ten. I've used this solution for so long and have seen it mature. It's just easy. In IT, especially in a managerial role, we want things to work. We don't want it to be complex. If it serves the business goals of data resiliency, then that's all I need.

Definitely do a proof of concept (POC) and make sure it fits your use cases. On paper, it will, but every company is different. Sometimes, for some reason, it won't work. Or not that it won't work, it just doesn't fit what the business is trying to achieve. So do the POC and see for yourself if it works.

We store a lot of raw data for reporting and use Zerto to protect that data.

Before implementing Zerto, we lacked a data protection and recovery solution, resulting in a significant data loss incident of approximately 70 percent during a past event.

Zerto is easy to use.

The near-synchronous replication offers a critical advantage for our customers' multi-platform environments by providing continuous data protection with minimal delay.

The main benefit of Zerto is that it doesn't affect the performance of the cloud platform while protecting the data. We realized the benefits of Zerto within the first three months.

Zerto's implementation has significantly improved our recovery time objective, allowing us to get our systems back online much quicker.

Zerto has significantly improved our disaster recovery capabilities, reducing downtime from days to just two hours.

With Zerto in place, our disaster recovery time has been reduced to a maximum of two days, whereas previously we lacked a recovery solution altogether.

Our disaster recovery testing with Zerto exceeded expectations. We aimed to restore all data within five days, but using Zerto's capabilities, we achieved a full recovery in just two days.

Zerto saved our staff three days of work, freeing them for other tasks.

Zerto's continuous data protection, journal-based recovery, automation, multi-cloud and hybrid cloud support, and non-disruptive testing have significantly improved our IT resilience strategy. These features not only enhance data protection and improve our Recovery Time Objective and Recovery Point Objective but also provide the flexibility and scalability needed for a robust IT environment.

It facilitates a cloud-based disaster recovery solution, eliminating the need for a dedicated physical data center to ensure business continuity in the event of an outage.

Zerto was our disaster recovery solution of choice because it offers a cloud-based implementation, which perfectly aligned with our organization's prioritization of cloud-based disaster recovery.

It stands out for its user-friendly approach to data protection and recovery, allowing for quick and efficient backups and restores.

Zerto's pricing structure could be more competitive to better suit the needs of a wider range of businesses.

The setup process could be simpler. A more streamlined installation would improve the user experience.

Zerto's long-term data storage capabilities, specifically how long data can be retained and managed, could benefit from further development.

I have been using Zerto for ten months.

We sometimes face challenges that require multiple hours of downtime but it is rare. I would rate the stability eight out of ten.

Zerto is expensive.

The technical support is quick to respond.

Positive

Integrating the initial deployment into our infrastructure proved to be a complex undertaking.

To ensure a smooth implementation, we prioritized planning and engagement, starting with management and then incorporating other stakeholders. We piloted the project with the operations team for a month before a full organizational rollout.

The deployment took around one week and involved six people.

The implementation was completed in-house.

Zerto provides a return on investment through the peace of mind we get knowing that all of our data is protected.

Zerto is expensive.

After considering both Commvault and Carbonite, we ultimately decided Zerto was the best fit for our data protection needs.

Zerto emerged as our choice for data protection because its feature set directly addressed the specific needs of our organization.

I would rate Zerto eight out of ten.

Maintaining Zerto is manageable as we have a dedicated team of three people responsible for its upkeep.

Our organization consists of 40 analysts in one site.

Zerto provides robust data protection and excels in disaster recovery for businesses, but its cost may be steeper compared to other solutions.

We use Zerto for the disaster recovery capabilities that it provides us. It is for our Tier 1 applications. 

Zerto allows us to protect individual VMs. With the other solutions, we are protecting the storage that the VMs live on, which is costly, so Zerto does save us money.

Zerto has near-synchronous replication. It works very well. Our RPO or recovery point objective time was 20 minutes, and we were doing thousands of VMs. We not only met the RPO; we exceeded it. There were many times when it was just seconds behind.

We have used Zerto to help protect thousands of VMs in our environment. Zerto has had a good effect on our RPO. It has helped to exceed our RPO. Our RPO on some of our critical systems is 20 minutes, and we exceed that. Most of the time, we are under 2 to 3 minutes.

It is very easy to migrate data. We ended up migrating from one data center to another data center, and we moved 20,000 virtual machines with Zerto. It was great.

Zerto lowered our RTOs as well. As a part of the solution analysis that we did for the RPO and RTO, Zerto's interface to do a DR test or a DR recovery was the fastest. We had a 24-hour window to recover 5,000 virtual machines, and we were doing them in three to four hours.

Zerto has helped us to reduce downtime multiple times. We had one incident where we used it to do a recovery. The downtime was roughly about 20 minutes. We do not have a value on that because it is customers' health information. I do not know how it affected the end users or customers outside of our company, but it does affect them.

Zerto has saved us time. When files were deleted, we were able to recover the files quickly. While doing OS patching on the servers, when the servers failed on the reboot, we were able to recover all good things when it came to quick recovery on it. As opposed to pulling it from our backup, it has cut our time probably in three quarters.

Zerto has helped to reduce our organization's DR testing. A DR test or a recovery used to take us days, whereas now, it takes us hours. The system that we were using before took multiple engineers to do the DR test, whereas today, a single engineer can do the DR test, and then we need just a couple of engineers to do checks on it, so it saves us a lot.

Zerto has reduced the number of staff involved in a data recovery situation. Instead of a group of people, we now just need one.

We used Zerto for immutable data copies. It was good, and they were on a course, but they shifted their focus. They were doing DR specifically, and then Zerto started shifting over towards doing backups. We were very excited about their long-term backups, but when HPE bought them, HPE stopped that part of it because they were directly competing against their solution. At the time they were doing it, we were very excited about it.

The DR testing capabilities that it has are valuable. 

Its ability to roll back if the VM or the server that you are recovering does not come up right is also valuable. You have the ability to roll back a few seconds or a few minutes. The rollback feature is great.

While going in, we were looking at the backup tool so that we had a DR tool and a backup tool, but they stopped developing their backup solution built into it. That was a bummer for us, so now, we have a DR solution, and we have a backup solution.

For the actual application itself, we have put in our request for certain features, and so far, they seem to be adding those features. In their latest one going to version 10, they did an appliance, which we had asked about 6 years ago. It is great to see that they are doing an appliance. There would be even more savings for us now because we do not have to pay licensing for a Windows VM.

I have been using Zerto for about 7 years. I have used Zerto a few times at different companies.

We have seen very few issues. It is one of the few solutions that actually runs. If you do your leg work and implement it right and go through all the design and other things, you do not have to babysit the solution. Care and feeding is what it amounts to. That is all you have to do, whereas with a lot of the other solutions, you have to babysit them.

Its scalability is very good. It scales very easily.

They could do better in regards to escalating an issue. I would rate them an 8 out of 10. In defense of support, I know it is hard because they are talking to somebody who has got 28 years of IT support. When I get on the call, I am probably dealing with someone who is just starting out. He has to go through his standard process. However, somebody like me is looking for faster support and would like to get to a real smart guy quicker.

Positive

For disaster recovery, we were using VMware Site Recovery Manager, and it was not able to provide the recovery, the RTO, or the RPO that the company required. I went out and did a discovery for different DR solutions, and that is where I came across Zerto. Zerto replaced VMware Site Recovery Manager, and it saved us millions.

Our deployment model is hybrid. I was involved in the initial deployment. It was straightforward. It was a lot easier than VMware Site Recovery Manager. It took us a week to deploy it.

In terms of maintenance, other than typical patching and upgrades, it does not require any maintenance. VMware Site Recovery Manager required a lot of ongoing maintenance.

We implemented it in-house. There were just three of us involved in its implementation.

The pricing is based on virtual machines. They need to do better in regards to their tiering pricing rather than one price per VM. A lot of times we have VMs that are lower tier, such as Tier 2 or Tier 3, but we pay the same price as for Tier 1. I know they are developing this out, but it would be nice if they could provide a little better pricing in regards to their tiering protection.

We tested four different solutions, and Zerto was the only one that was able to meet our requirements. We did PoC on Zerto and two other solutions. Zerto was by far the leader when it came to disaster recovery.

To those evaluating this solution, I would recommend doing a PoC on it. Deploy it in your environment and test it. Most of the problems you are going to see are due to the replication, and that is the site-to-site connection. One of the problems that I have experienced with Zerto has been related to replication, not the solution itself.

We have not used Zerto for blocking unknown threats and attacks. Thankfully, we have not had that. We do not have experience of that, thankfully.

We have used Zerto to do DR to both AWS and Azure, but the ability to do disaster recovery (DR) in the cloud is not something critical for us because the health insurance requirements for certification do not allow us to put our Tier 1 data in the cloud. Also, because our applications are multi-tiered where they reach out to the mainframe, Solaris, and other equipment outside of the virtual environment, it did not make sense to go to the cloud with it, but we do have it. We have a development environment there. A lot of times, we will use it to refresh the development environment. So, it is important, but in our case, it is not critical for us. 

We have not had any issues utilizing Zerto to support DR on AWS, but AWS is on the slower side. The reason is that for the connection to AWS, even though it is a direct connection, the speed does vary for us.

I would rate Zerto a 10 out of 10.

We use Zerto as our disaster recovery solution for our servers in the multiple data centers we have. It allows us to replicate our servers from one data center to another and perform disaster recovery testing to ensure compliance with our organization's DR requirements.

Our organization wanted a solution for replication, whether for VMs or Azure sites, and the ability to migrate servers or VPGs in case of a disaster or for testing purposes. And we wanted something reliable.

We're migrating out of one of our older data centers currently, and sending them to either Azure or one of our two VM data centers. We've been working on getting all the servers out of the old data center for a year. Being able to migrate those servers, with the help of the service teams, is one of the best features. Instead of having to do them one at a time, we can build a VPG. That is especially helpful with some of these really large VPGs. We did one a couple of months ago that was 36 terabytes. We were able to migrate that entire VPG at one time, watch it replicate once it was there, and then do the reverse replication. That process has been amazing.

We use Zerto to protect VMs and our RPOs are very solid. The RPO is a little slower for Azure, but that was expected and it was covered in the documentation that Zerto provided. But the RPOs from one VM center to another are solid. The same is true for our RTOs. We have no complaints in that regard at all.

And it will definitely help reduce downtime if we have to migrate from one data center to another due to a disaster (which we have not had to do so far). Downtime would cost us a lot, no doubt. We have not had any major disasters as of yet or problems with spyware or ransomware. But we have had instances where a server was corrupted in one data center and because it was backed up with Zerto, we were able to fail over to the secondary site and get the VPG back up very quickly. From the time that the decision was made that we needed to fail over, it took around 30 minutes. It was very quick, especially compared to trying to troubleshoot and rebuild. Our patients weren't affected.

The platform has also helped us to streamline our DR testing. We're able to do our annual test as quickly as possible, whether it's a failover rollback or a system move. It has made that process much much quicker and a lot less painful.

I've only been in this position for a year, but from what I've heard, DR testing was not a pleasant experience prior to moving to Zerto. They were always having failures and then would have to set up another downtime and test again. With a lot of our applications, those that are tier-ones, we're having to do the DR test at 1 AM or 2 AM. Nobody wants to have to do a four-hour downtime test multiple times.

And not having long downtimes for DR has helped a lot. Our customers and service teams know that we have to do these tests once a year to stay compliant. We plan for a four-hour downtime every time we do a DR test. Very rarely do we need four hours. We block out that time just in case there are issues we didn't expect but we're usually done in under two hours, including failing over, doing the testing, rolling back, and testing again. I don't know if you can actually put a number on not having downtime, in terms of the impact on the service teams, nurses, or patients.

Right now, our DR team is just me and my boss. At one point, there were three people on the team. It says a lot about Zerto when it can be used with a minimal staff for DR. Prior to moving to Zerto, the team had four members. So it was double what it is now.

The replication works really well. We perform multiple tests a month and annual tests for our tier-one and many of our tier-two apps. We need to make sure we can quickly and reliably migrate VPGs to the backup data center in a disaster scenario. Migrating systems as a failover rollback or a system move are two of the functions that I like the most.

It's also very simple to use. For example, when we need to move data so that our users can keep collaborating with one another, using Zerto is very simple. Putting the servers into maintenance mode and either moving or testing them for our teams, has worked very well. We have found very few hiccups with any part of the solution, especially with the new version that they released recently.

The near-synchronous replication-also works really well. When you move or have just built a VPG, watching it step through things is great. It's a well-made product. Near-synchronous replication is very important, making sure that it's done properly and that it's complete.

We have Azure data centers. When migrating out of our older data center, if we find that Azure is the best place for those new servers, we have been migrating them there and doing the DR test at the same time. I haven't found any problems with migration to the cloud. For our applications that will work in Azure, Zerto's disaster recovery in the cloud has worked really well.

I turned in a ticket a while back when I found a glitch within Zerto. When building out a VPG and doing the machine types within Azure, they were not coming across correctly. It would say it had a CPU and memory of a specific type, but it was not accurate. When I sent that ticket in, the support manager said that it hadn't been found before, but that my report was accurate and that it was a bug, and that they were working on it. 

But I've been very pleased with the updates that they put out and the service. I don't have a lot of negative things to say about Zerto.

I've been in this position for a little over a year and have been using Zerto during that time.

I've never seen it go down. It has been stable and easy to use, which are some of the main reasons we're still with them. We haven't had any large bugs with it. The software seems to be well-tested before new updates go out.

We have it deployed across three on-prem data centers in two different states, plus the two different Azure sites that are also out of state.

We've added a couple of new data centers since I've been in my position and adding them to our Zerto interface was not very difficult. The scalability is good.

Whenever I have had any issues, I have contacted support and they have been knowledgeable. Getting a hold of Zerto's support has been easy. In general, compared to all the other applications that I've ever supported in my career, Zerto has been one of the easiest to contact and actually get help with. I've worked with some vendors that were really difficult to work with.

Overall, Zerto's technical support has been fantastic. When I've had issues, submitting a ticket online is fast. In all but maybe one instance, I had a callback within just a couple of hours. Their support has been awesome.

Positive

Our organization migrated away from a couple of other solutions prior to my starting this position. But the disaster recovery manager that I work for has said multiple times that Zerto is the easiest solution and has the most robust features compared to whatever they were using prior.

I know our organization still uses Veeam, but they do so in tandem with Zerto.

There is an annual cost for Zerto, but that is something that our director level works through. Our organization, St. Luke's, goes through all vendor contracts looking for the best value. The fact that we have been using Zerto for a few years says that the value must be there compared to other vendors.

Not having to take down our tier-one system for an extended period of time for DR testing is invaluable. You can't put a dollar value on the impact on a patient's life. We need our systems to stay up constantly because they are what keep people alive.

In terms of maintenance of Zerto, we do our monthly reboots of the servers so that they stay up to date with the Microsoft patching. And anytime that Zerto has updates to their software, we make sure that we stay compliant with that. And once every year or 18 months, we update the cert on the servers.

My advice is to look for a product that is easy to use and easy to learn and allows for scalability and DR testing that works well.

In my previous company, I used it for disaster recovery. We protected our critical workloads in another data center where we would replicate our primary workloads.

In my current company, we're in the middle of a data center consolidation project and we're using Zerto in two ways. First, we're migrating the workloads we had in one data center to another, about 250 servers. It took us about three months to complete the migration. We had to schedule all of our moves and work with the business to validate that the services were fine and accessible, once they were moved to the other data center. We've completed the migration and a data center has been shut down, and we're working on building disaster recovery for our primary workloads in Azure.

The main benefit is that we are centralizing our disaster recovery solution. Before, we were doing replication for some services and RecoverPoint for other services. We had a mix of tools for disaster recovery and we're trying to simplify that process with a product we can use for both. We're even contemplating using Zerto for backups as well, because we use other tools for that. But the main focus is having a specific tool, Zerto, that we can use to achieve our disaster recovery goals for on-prem services.

We also have a big push to move our DR solutions into Azure as a result of a decision from our upper levels to use Azure as our primary solution for building applications. That has allowed us to reduce costs and consolidate from three data centers to one, with our disaster recovery solution in Azure. Our focus on one tool has made it simple. We're still working through that process. Whereas the failover solutions in Azure are somewhat the same as any other data center, building out the rules and requirements for firewalls is a little more complex. We have some third-party vendors that are helping us design and build out our security into Azure.

Near-synchronous replication is one of the benefits of Zerto that drove us to choose it over some others. With typical backup and recovery, your recovery point can be 24 hours. With the near-synchronous replication, our recovery point objectives are in the seconds. That's one of the major benefits of Zerto. We don't have to run incremental backups every half hour or 15 minutes. And the recovery time is fairly quick as well. It's essentially just a shutdown and reboot of a VM.

Near-synchronous replication is incredibly important for us because we have transactional applications that work on financial and transactional databases. The fewer the number of transactions that are potentially lost, the better it is for our organization. It means we don't have to go through rebuilding those transactions. It limits the amount of data that we could possibly lose in a disaster recovery situation, amounting to just a few seconds' worth.

The near-synchronous replication with Zerto has enabled us to reduce our RPOs to two seconds instead of hours and, sometimes, days.

And Zerto really improves RTOs for moving applications. You're not waiting for restores to happen. In some cases, if you have large amounts of data on the order of hundreds of terabytes, it could literally take you a week to recover certain applications, especially if you're pulling the data down from Azure or offsite storage. Zerto greatly improves the amount of time that it takes to recover. And you don't have to do one at a time. You can move over a large chunk of servers at once and get those recoveries running and mounting in your disaster recovery environment. It's a lot quicker than running a restore from a restore product.

In addition, the solution reduces the amount of downtime we have in applications during migration. We had a large number of servers, including some critical production applications. But we didn't have to find windows where we could have those systems interrupted for a short period of time. A few minutes of downtime, compared to having the application down for hours, helped move our migration project along. We moved about 250 servers in a three-month period, and we didn't have any issues with any of the applications related to data or the like. We had two instances where there was an issue related to licensing but they were our only issues when moving these applications.

The auto-connect feature is valuable because we can set the amount of time that we delay before committing a move from one location to another, giving application teams time to validate that the move went well and everything is working before we commit those changes. That gives us the ability to roll back to the same point we were at before we shut things down, if needed. 

Another nice aspect of the product is the non-intrusive failover of the application, similar to an actual disaster recovery test without impacting the services that are currently online. We can failover to an isolated environment and validate the application without impacting the production environment. We can do more testing in a non-impactful way using isolated testing. And once or twice a year, we'll do a live test that is more like what would happen if we lost a data center.

Zerto is also a very easy product to use. Although I've used it before in other environments, we introduced it to some engineers on our team and, after a couple of hours of training to go through the product, it's fairly intuitive. It's not something that takes a five-day training course to understand. You just drive through the checkboxes to build a protection group and that's pretty easy to do. You don't really have to understand coding or the like. It's GUI-driven, so it's fairly easy for an engineer to create protection groups.

You can use Zerto as a backup product, but in the discussions that I have had with them about the product, they don't really sell or talk about that feature as much. So I would be interested in improvements related to using it as a backup. If I could consolidate and use Zerto for disaster recovery as well as everyday backup and restore for situations where I need to recover something, that would be helpful. It has some of that functionality, but it's not something they promote a lot. They should point out the benefits of using Zerto as a backup and recovery product instead of just a DR product.

With Cohesity, we keep a limited amount of backups, about 14 days. That way, we can recover an individual server within the same site or we can restore data or databases that we need, in a non-DR way. We use it for typical day-to-day backup and restore. If we could use Zerto in a similar fashion for everyday backup and recovery scenarios, that would be another area where we could consolidate into a single application.

At my old company, I used it for several years, and at the company I'm now at we've been using it for about a year.

It has been rock-solid. I haven't had any issues with any of the builds or the virtual managers. It just runs.

It's really scalable. You can create as many protection groups as you need, and a lot more than we have in our environment. 

We do have some sites that are very low-bandwidth sites. Zerto is able to set throttling in the solution, but the throttling is set at a site-wide level. In those instances that have very low bandwidth, I can't reduce the throttling on that site. It would be nice if there were a way to control the throttling by the protection group for a specific workload.

Our experience with their tech support has been good. I have never called them with an issue that they couldn't resolve fairly quickly. 

I did call them a few times on some migrations that we were doing off-hours where certain aspects of the migration didn't work, particularly on the reverse protection. I always got a callback within 30 minutes and most of the time it was quicker. The support has always been great.

One of the main issues was handling large data migrations. It wasn't feasible to do a big-bang move where we could move everything at one time, so we needed to schedule moves. We were able to at least replicate the information and work through a schedule for the migrations quickly. One of the major things we were trying to adjust was having to schedule the migrations and working with the team to validate that everything was functional. We were also looking to minimize the amount of time that that service would be offline during migration.

In addition, we use a combination of tools. We were doing replication with RecoverPoint, and straight backup and restore with Cohesity. While we still use Cohesity, we did get rid of RecoverPoint and we don't use VMware Site Recovery Manager because we're not recovering from VMware to VMware anymore. Cohesity does certain things and Zerto does certain things very well.

The implementation of the migration was very straightforward. The implementation of disaster recovery into Azure was a little more complex. In part, that was because of the way our company built our Azure subscription and the rules we have in place for installation and dividing things and networks within Azure. 

But from the standpoint of installing and deploying the product, it's very simple.

We did it in-house, but we did have a Zerto engineer run through the installation into Azure with us because we did run into some issues related to permissions in Azure and some of the custom roles that are defined. We also worked with an engineer from Azure to help us, mainly around the identity portion in Azure.

On our side, it was just me and one of our other engineers involved.

We have seen ROI on the migration project which didn't require a whole bunch of people involved. We rotated two people who were able to facilitate the migrations when we scheduled them in the evenings. Sometimes, we would do up to six or seven migrations in an evening. 

The main thing that held us up a little in that project was the validation process required by the business. If we had been able to just run through it, we probably would have completed it a lot more quickly.

Still, we didn't require a lot of resources to do it. It was just one engineer to handle a migration and the applications teams to validate. We didn't have to go outside the company to hire services to help us with the migration. That was helpful from a cost perspective.

Pricing is one area where there could be some improvement. We would like to see a consumption model that would charge in a DR scenario, where you're failing over and consuming those resources, instead of a per-protected-node model. Or it could be a model based on the amount of storage space you're protecting.

Others in our organization have raised the issue of how it's licensed, where you need one for every VM you're protecting.

We looked at RecoverPoint and Site Recovery Manager in VMware, but they just didn't fit the type of scenario that we were looking to set up with replication and recovery into Azure. We couldn't really find too many tools that were doing it in a way that was not too intrusive. There are ways you can migrate things into Azure and run them, but there's a technical process that you have to go through to make it happen. 

We were looking for a solution where we wouldn't have to flip all the switches for Azure. We wanted something straightforward that was much simpler to use. Zerto was really the only tool that we could find to do it. Others that we looked at briefly just didn't do what we wanted to do, so we didn't spend too much time on them.

Recovery with Zerto is a little more straightforward compared to other solutions, and the amount of time it takes is fairly short. You can recover with Cohesity fairly quickly, but there are a bunch of other things that you need to do, depending on how the recovery is done. If you're mounting a new virtual machine from a snapshot, which would give you a fairly quick recovery, you would still have to re-synchronize that data to keep it as a replication, and that takes some time. 

Zerto is just a more straightforward solution. You're getting pretty much the same server restored in under a minute, which is the time it takes to reboot, sync, and bring it back online. Other tasks you have to do, when bringing something up in another data center, like re-IP the machine, can be automated in the Zerto replication. It makes things easier.

My advice is to look at what you're trying to accomplish. If you're looking for a migration tool, this is a great migration tool that will help you move workloads between data centers. It's agnostic as to whether you're using VMware, Microsoft, or Azure.

And you have to look at whether you're moving a large amount of data or a large number of servers. Think about how much downtime your business can afford for moving those applications. If you're looking for something that can move an application with minimal downtime, this may be a solution for you. Or if you're moving large amounts of data, but you don't want to be down for the whole time you're restoring or moving, a synchronous product like this may be a solution for you.

We have built a disaster recovery landing zone in our Azure environment and we built an isolated environment so we could do non-intrusive failover tests into Azure, and still keep our production environment up and running. We've tested certain workloads failing over into Azure, including a standard Windows or Linux box, and specific things like SQL Server, Oracle, et cetera. It has been going well so far and we're at the point where we're defining our protection groups and security in Azure for all of our critical workloads.

We have not yet used the immutable data copies feature, but I was just at a conference and had some meetings with Zerto, some of the product professionals and engineers, and that is something that we are strongly looking into. That's because of the issue of cyberattacks and because even backup systems could become corrupted and then you're still in a bad situation. Putting the data into an immutable repository is something that we are definitely looking into. Especially in the industry that we are in, cybersecurity is a big issue.

We have also not used it for blocking threats and attacks. But the ability, in conjunction with immutable data and putting that into a vault, to look at the data that is being replicated in real time and scan it, would be a great benefit. We do use some of the best-in-class tools for that kind of protection, but this would just be another layer to help with that. It's an interesting feature and another tool that would add a layer to our cyber protection.

Zerto hasn't reduced the number of staff involved in backup and DR management. We have a pretty lean team. We try to cross-train our employees on the different products that we use. But Zerto did help to simplify the process because we can get people trained on it. They can assist in covering for other people in the group when they're out. The training only takes a couple of hours to go through the tutorials.

Our primary use cases are for disaster recovery, data center movement, long-term recovery, and backup recovery.

Zerto took our disaster recovery practice from sixteen hours down to thirty minutes. 

The most valuable feature is the fully automated failover. The orchestration made the failover very easy for anyone who wasn't necessarily technically knowledgeable to be able to failover a machine.

I love Zerto's near-synchronous replication. I've been using Zerto for three years at my current employer and many years before that. It's been great. Anywhere I've used it, it's made the failover process a lot easier so that pretty much anybody can do it. This feature is our number one priority because we can keep our critical apps running if we have a failure, or even if we have a misconfiguration, it's very easy to recover something quickly.

We've moved some of our workloads to the cloud and back from the cloud using Zerto. The native tools provided by the cloud provider were not as seamless. Having DR in the cloud is very important to us because we trust that the cloud provider will provide a solution, but we also want to make sure that for our business purposes, we have a backup to disaster recoveries so that we're able to recover somewhere else if necessary.

We use Zerto to support DR on the AWS platform. We go between two different clouds. We go from VMware to Azure and also AWS.

Zerto made this quite seamless, especially going between two different clouds. It's just a matter of a couple of clicks. You don't need to understand what's happening on the back end.

We use Zerto to help protect VMs in our environment. It took our RPO from around four hours and now it could be seconds. We can recover the machine in under a minute as far as the boot time. We're between five and ten seconds RPO.

The magnitude of Zerto is much faster. We used to do a disaster recovery failover of our critical systems. It took about sixteen hours and once we had implemented Zerto, it took around thirty minutes to do for the same exact systems.

I would like for them to support additional hypervisor options. They support VMware but if they supported Hyper-V or Nutanix, it would be beneficial.

We have been using Zerto for three years. 

It's been great. We've had it for three years. The only time we reboot the machines is for normal patches. We don't have to do anything else. It just works. We don't have to think about it. We've never had any issues over the three years we've been running.

We started Zerto with a small footprint. We only did a few VMs as a POC with two nodes on each side. Then we've grown it to 34 nodes on each side, including the cloud. It's always the same amount of resources. We're running 150 protected VMs in there. It runs really well. 

The few times we've had to use customer service, it's never been for anything that was really broken. It's more informational or because we didn't understand how the product works. They've been great with communication, they get back to us, and even if they don't get an answer right away in one day, they'll let us know with the ticket updates that they're still working on it. 

It's been really good as far as the little interaction we've had. The one nice thing is that we've never had to use it for anything that's been broken or that it's not working.

They have great communication. They don't just send you links to KB articles. 

Positive

We looked at other solutions before we purchased Zerto. We did a bake-off with a couple of other solutions. Zerto blew everything else away. The functionality is the same as everybody else, but the amount of time it takes to implement Zerto is a lot quicker. 

Making changes if you want to add another machine or another workload takes virtually seconds, whereas we found other systems took a planning time and could take hours to get implemented correctly.

The setup was great. We had one of our newest engineers run through it because as part of the POC, the salesperson showed us how to install it. It was very straightforward. We took somebody who knew nothing about Zerto, had them install it and they had it installed and running in about fifteen minutes. It is quite easy to use. 

I can't say it's the same for SRM. There's a lot of documentation, whereas, with Zerto you point to the button, you push, and it works. 

We did the full installation ourselves.

We got the recovery time from sixteen hours to thirty minutes. Prior, when it took sixteen hours, there would be about ten or more people who were waiting for systems to come online to be able to test. 

With Zerto, within an hour, we get the systems up, and then it's thirty minutes to test. Everybody can go home. There's a lot less time for people to be available. Zerto makes it much easier and quicker to get completed.

The licensing model per VM is great. It's a good way to license it because you want to protect only the devices that you're looking to protect. As far as getting the licensing and working with the sales team, they're very responsive. There's a lot of great communication, it's good all around.

We looked at VMware SRM. We also looked at a manual process. We chose Zerto for the simplicity and the cost ratio was phenomenal. It's easy enough that we've had nontechnical people able to failover just by clicking a button. 

For Zerto, you add the VM in the VPG or workload, point it to the target, pick where you want it to land, hit go, and it's done. With SRM, in comparison, you'd have to make sure it's being replicated between the two SANs. You have to go to a different UI, configure all of it, make sure that's working, then go into SRM and configure all the orchestration parts. It takes a lot more planning. You really have to make sure that all the different systems work together, whereas Zerto takes care of all that for you.

I would rate Zerto a nine out of ten, there is some room for improvement. The drawback for me is that it's not compatible with every single hypervisor. If we wanted to go with another vendor for a hypervisor locally, then we'd have to look for a different solution, and there's nothing really out there that is comparable to what Zerto can do.
