Zerto Reviews

We implement Zerto as a part of a Disaster Recovery process for our valuable customers, in various environments. Most of them consist of two sites owned by the same customer, connected with campus or wan link, but both using VMware virtualization platform.

Recently we realized a dedicated infrastructure in our Datacenter, then started to propose to our customers DRaaS using those resources as a recovery site and including dedicated 24x7 support. 

Few customers use the public cloud (Azure) as a recovery site: we could only implement and configure the solution or fully manage it because we are also a Microsoft Gold and Tier-1 partner.

Zerto helps reduce downtime in a wide number of situations because it can bring up an entire environment of 40-50 VMs in minutes. 

Zerto helps to save time in a data recovery situation too. Some customers experienced VM or database corruption: using the solution's checkpoint feature, the data recovery happened within five minutes or less. A normal restore would probably be two to eight hours depending on if we had to restore from disk/tape and need or not need to apply logs.

Zerto is great at DR testing. We can spin off critical VMs or an entire environment pretty quickly and have users test against this copy with no production environment impact.

Its overall impact on our RTO has been great. It took a few hours in a very complex environment. The customer was very impressed with Zerto when we started with the PoC and then put it in production. It is great.

Zerto has reduced our downtime. Customers have minimal downtime. 

We have been enabled to automate tasks with Zerto. Staff can now be dedicated to other tasks.

A great Zerto feature is the non-intrusive failover of the application, similar to an actual disaster recovery test without impacting the services that are currently online. Sometimes customers need to failover to an isolated environment and validate an application without impacting the production environment: we can achieve this goal with Zerto. Again, we can do regular testing in a non-impactful way using isolated testing. For customers of our DRaaS we include once a year, a live test that is more like what would happen if the customer lost the production site.

Eventually, the VPGs (Virtual Protection Groups) allow to grouping of one or more VMs into a single entity, ensuring every point in time inserted into Zerto’s journal (a checkpoint) is from the same point in time for all components within the protection group. This allows easy recovery of an entire application and its dependencies to a consistent point in time.

Zerto is also a very easy product to use.

We started using it a few months ago for immutable data copies for a few customers on multiple repositories like HPE.

Zerto's ability for blocking unknown threats and attacks is key in our disaster recovery process. It's the technical solution where we implement all the data. It is also the recovery plan for our customers.

We have tried experimenting implementing Zerto with the the disaster recovery site on cloud. We use an Azure. It's very useful. Zerto has enables us to do disaster recovery in the cloud, rather than in a physical data center.

We've only used Zerto two or three times to migrate an existing data center to a new one because the hardware under the machine was from a different brand. We used Zerto because the environment is quite complex and the migration using other tools did not fulfill the customers' needs. Zerto is very good at data migration.

One of its best features Zerto is the ability to maintain the data of multiple VMs using Vipro Protection Group. We can aggregate multiple VMs in a workload for specific services. They are protected at the same time. 

It's very easy to manage and monitor our DR plans with Zerto. It's very easy to learn and operate. It's easier than VMware. 

Zerto could be considered as a backup product but this is not true. So if we could consolidate and use Zerto for disaster recovery as well as everyday backup and restore for situations where we need to recover something, that would be helpful. Anyway, we think that Zerto will win with no competition in the Disaster Recovery process, so we stay focused on this.

Now we are testing version 10 which include real-time ransomware detection, a new Cyber Resilience Vault and enhanced cloud capabilities and security: we expect more from these features for superior hybrid cloud security.

Reports could be useful for customers. I would like to have a report that shows the latency for every single internal VM. it would be useful for troubleshooting.

We started to evaluate Zerto about three years ago, then we implemented it for our valuable customers who need affordable solutions in their disaster recovery processes.

We haven't had any issues with any of the builds or the virtual managers, especially with the new "appliance" mode. It just runs.

Zerto is a very scalable solution. We can create as many protection groups as customers need for their environment even as they growth. 

Our customers are mostly medium to small sized enterprises. 

We use Zerto Quick Start service for the first installations and we use it in very complex environments: great. 

We are very satisfied. We had to use it at the beginning to understand the implementation process and what we needed to do. 

They are quick and professional. 

Positive

We previously used Veeam (B&R + DRO) and VMware (Replication + SRM), but they could not offer all the features of Zerto.

We also sometimes still use VMware Disaster Site Recovery Manager in conjunction with VMware Backup and Recovery. 

The implementation is very straightforward.  Must be considered security and lay out the network infrastructure to be more efficient.

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

Pricing is adequate at the standard of the product, but there could be "always" 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.

My advice is to look at what you're trying to accomplish: with Zerto you could combine resilience, mobility, and protection into a single software-only solution. It's hardware and hypervisor agnostic as to whether you're using VMware, Microsoft, or Azure.

We have built a disaster recovery landing zone in our Datacenter and we built an isolated environment so we could do non-intrusive failover tests, and still keep customers' production environment up and running. 

We have recently introduced the immutable data copies feature, because of the issue of cyberattacks and because even backup systems could become corrupted and then this is still a bad situation. The ability to look at the data that is being replicated in real-time and scan it, in conjunction with immutable data, and putting that into a vault, would be a great benefit. 

The 3-2-1 rule isn't so important for us when it comes to disaster recovery. We consider the backup process and then the disaster recovery process. We treat them as two different workloads that we could implement to our customers to solve different issues.

The majority of our customers use it in a hybrid environment, but they prefer to use disaster recovery in their own data center. In some cases, we provide disaster recovery as a service, where the disaster recovery site is in our data center.

Doing a proof of concept is the best way to implement and sell Zerto. The customers don't always trust our advice but when I start with a POC in their environment, they see it's benefits. 

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.

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.

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.

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.

I have been using Zerto for three years.

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

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

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.

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.

The Zerto team assisted with the implementation.

We have seen a return on investment.

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

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

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.

We're backing up VMs with it. Our company has about 200 VMs and we're using Zerto on 30 of them in the main line of business applications. We're using it to replicate all that data over to our DR site so we can do our testing and reporting against that. 

Within those 30 servers we've broken out into three different SLAs on which ones get spun up first. We have it all scripted with monthly plans to fail over, spin it up, actually use it over there, spin it down, bring it back into production, etc.

The business that we're in means we have to run our network 365 days, 24/7, with no downtime. If there's any kind of interruption to business processes — power outage, tornado, fire, etc. — we need to be able to get certain systems up and going in almost real-time. That's how we're leveraging Zerto, to guarantee that uptime and for the ability to spin these things up near-instantaneously.

I know my networking team loves the tool and the interface and being able to roll back and do the failover stuff very easily. But for me, personally, it's how it has impacted our business. The reporting functionality showing that our DR plan is rock-solid and stable, and my ability to generate summaries for our customers, have really improved business processes for us. It gives peace of mind to our customers that our systems are stable and the services that we're providing are stable.

Also, when we need to failback or move workloads, Zerto decreases the time it takes and the number of people involved. The failback feature, from a technical standpoint, is what sold us on Zerto. One of the challenges we had with Site Recovery Manager was spinning up and being in production at DR. If everything is equal, everything is patched and everything's working, both solutions offer a very similar experience: the ability to move a workload from production to disaster recovery works with both of them, no problem. Coming back the other way was just a bear of a move with Site Recovery Manager. With Zerto, it's almost seamless. With Zerto, it takes about four or five mouse clicks and stuff fails back over, and our end-users are none the wiser. And it's just one guy doing it. When failing back from Site Recovery Manager, we'd have to get one of our sys admins involved and we'd have to let our end-users know that they all had to log out.

While it hasn't reduced staff, we have become more efficient and it has allowed me to reprioritize some projects. It's freed up some capacity, for sure. We haven't reduced headcount, but it has definitely taken a big wedge out of the daily grind of our backup and recovery; the stuff they always had to check.

Personally, what I find valuable is the executive summary that says our DR plan is operational. I can then pass that out to our customers. 

Per Mar has about 75,000 customers and, more and more these days, especially given all this [COVID] pandemic, we're asked: Do you have a business continuity plan? Is it tested regularly? Do you have documentation for it? Two years ago, a simple email from me saying, "Yes, we have this," sufficed. We're finding now that people want true documentation from an independent system that generates a report. The reporting that comes out of Zerto is a lifesaver for me. I'm able to generate that up, send it out to the customers that need it, and say, "Yes. Here are our SLAs. Here is our monthly test routine. Here is where it shows us being successful," and so forth.

We are doing continuous data protection. It works flawlessly. Our recovery points are measured in seconds. We have all these "baby snapshots" throughout the course of the day, so we can roll a VM back to any point in time, spin it up, and away we go. We're actively using that. It works great.

It's easy to use and there isn't a huge learning curve. Even some of the advanced features are very intuitive to folks who have been in this space before. If you have any kind of skill sets around any kind of backup and recovery tool, the user interface for Zerto is very natural.

One thing I would like to see, and I know that this is on their roadmap, is the ability to use long-term storage in the cloud, like in Azure or AWS, making that even more seamless. Whether it's stored in glacier or on-prem, being able to retrieve that data in a quick manner would be helpful. They're just not there yet.

I've been using Zerto for about a year.

It just works. We architected it pretty nicely. One of our licensed servers is a complete test solution for us to show that it is truly working. We're able to take a small test server, a Dev server is really what it is, and we can move from production, move it over to DR, have it run over there for a day, and then we move it back with no data loss. 

It's never not worked and when you come from the SRM world, that's just unheard of. Now we're a year into this product and have gone through an upgrade, and our June test went off without a hitch. It's very rock-solid.

Their tech support has been fantastic to work with. We ran into a glitch when we did our update in mid-May and our primary data center stopped talking to our secondary data center. We couldn't figure it out. We got their tech support involved right away. They identified a bug right away. They were able to roll us back and then stayed engaged with us as they figured out how to fix the bug. And once the bug was isolated and fixed, they got right back a hold of us to say, "We're ready to go," and then they walked us through upgrading both sides. There was a lot of hand-holding in that upgrade scenario. It was a fantastic experience.

It took them four or five days to fix the bug and they stayed engaged with us just about every single day, letting us know the status of it and when it went to QA. We didn't fall into a black hole. It was a very customer-centric experience.

We were using VMware Site Recovery Manager. We're still a VMware shop. Zerto replaced SRM. It was probably cost-agnostic, but what it really came down to was that SRM breaks all the time. You apply some patches or a Windows update. Uptime and reliability for us are super-critical. We don't have a ton of time to spend on making sure it's always working. We were really looking for a solution that we could architect, deploy, and just let it run, knowing that we're protected without our always having to go back and mess around with it.

What we kept finding with Site Recovery Manager was that every time we wanted to do a full-scale, failover DR test, we would have to spend a week ahead of time prepping for it, to make sure everything would work flawlessly during our test. It always worked, we knew how to patch it and get around it. But disaster doesn't give you a two-week notice. You don't know you're going to have a tornado in two weeks. You get about a 10-minute notice and then you've got cows flying through the air. We wanted a tool that we know would just run and work and be reliable. 

It was cost-neutral to the budget, the timing was right, and the solution was rock-solid so we made the change.

Ease of use and deployment are fantastic. This is a solution that we started with a proof of concept. We threw it in a lab and said, "Hey, let's just see what it looks like." Next thing you know, we never even had to tear down the proof of concept. Once we started seeing it working we said, "This is definitely something that we want." All we really ended up doing was negotiating licenses, applying the license key, and we were off to the races.

Soup to nuts, it took us five hours to spin the whole solution up and to create our protection groups. It was very fast. That includes downloading the software, spinning the VM up, and protecting and backing up data.

We worked with one of their engineers through the proof of concept. Once we said, "Hey, this is going to work," we tested it on a few servers and then we became a paying customer. They worked with us to help us define what made sense for the 30 licenses that we bought and what machines to deploy it to. But it's really not a complicated tool to deploy. There wasn't a ton of architecting and solution-building around it. There was some, but it was a very simple solution to install.

We have seen ROI. And even when you cost-compare against Site Recovery Manager, none of these solutions is cheap. But we are folks who need to have uptime and these things have to work. When you start comparing it against Site Recovery Manager, Zerto blows it out of the water, in my opinion.

If it were easier to license, and to scale it out a little bit more economically, that'd be a godsend. At the end of the day, my druthers would be to have all 200 of our servers protected by this platform. But for a company of our size, that stretches our IT budget and it just doesn't make economic sense. I would really love to be able to just apply Zerto to every virtual machine that we spin up, drop it into the right SLA bucket, and just be done with it, knowing that it's protected, soup to nuts. Unfortunately, that's just cost prohibitive.

My advice would definitely be to leverage the number of VMs. It's not a cheap solution by any stretch, but it delivers on its promise. There's definitely value in the investment. With hindsight, I would have gotten a better cost per VM if I was able to buy, say, 100 licenses. It would have been easier for me to put other servers under the protection of Zerto. I wish I would have had that flexibility at the time. Eventually, budgets will open up and I'll be able to go get another 50 or so licenses, but I'll still be paying a higher price, more than if I would have negotiated a higher quantity to begin with.

We took a look at a couple of other solutions. The other ones fell off the table pretty quickly. We're based in Iowa. We have a good account team here in Iowa from Zerto that knew our account from previous relationships. They came around and said, "This is a tool that you guys really need to take a hard look at."

The sales process took about six months. They came in about six months before my renewal with VMware. We had a few conversations and, about two to three months before the renewal, designed a proof of concept to see if it was actually going to work. They came in and did that. My guys were raving about it and I saw some of the reporting out of it. At that point I said, "Okay, done deal." It was cost neutral. When Site Recovery Manager came up, we canceled that portion of the renewal. There wasn't really a need for us to go out to market. I just trusted the account guys. They knew who we were. The tool worked the way they called it. I don't get too picky. If it works, it's good enough for me.

Take a hard look at it. Don't pass it by, don't be scared off by the price. Definitely take them up on the proof of concept. Have the team come in and do that. You'll be pleasantly surprised.

They talk about technology that can just actually do what it promises. I've been doing this for over 20 years and sometimes you get jaded by the fact that people over-promise and under-deliver. Zerto was definitely on the opposite end of that spectrum. The solution went in so easily that I had to do a double-take when my guys were telling me, "Hey, it's already up and running." I said, "It can't be done already." I'm used to complicated deployments. They promised and it does exactly what they said it would do. Don't be so skeptical. Keep an open mind to it and explore the possibilities.

I just sat through ZertoCON. They put a lot of emphasis on long-term retention. It really started putting a question out there as to whether you need a different backup and recovery solution. We use a different partner called Rubrik for backup and recovery. The challenge that we have with Zerto is that we're only protecting 30 VMs, whereas with Rubrik, we're protecting all 200. There's a little bit of a dance between value and return. So we're not using Zerto for long-term storage right now. We're evaluating it. I don't know if it makes economic sense to do so, but we are taking a look at it. And we're not protecting all 200 servers because of cost.

In terms of using the solution for a data recovery situation due to ransomware or other causes, knock on wood, we have not had to use it in that capacity just yet. We have a very mature cyber security posture and we haven't been popped by ransomware in the last year. But it does give me peace of mind that we also have that ability. That's just another layer of our cyber security posture and we know that we're protected against those threats. So there's definitely a peace of mind around that.

The only folks using it are on our IT team, about five or six of us. Five of my guys use it on a regular basis and know how to manage it. I'm the sixth guy. If I ever have to get in there, we're in trouble.

We use Zerto for disaster recovery and DR testing.

Zerto has improved our restoration time and made it easier to test software upgrades. It has simplified tasks like decommissioning a site and replicating virtual machines from one location to another. 

It gives us peace of mind that we can recover our systems in minutes or hours instead of days. Zerto is also helpful for insurance purposes. Our insurer wants to know how long we'll be down in a disaster. Of course, the company owners love Zerto because we won't lose business if something happens.

When we had a firmware failure, it saved us time performing a failover to our DR site. It isn't easy to calculate, but it saved us days and possibly weeks of downtime. 

A firmware update on our SAN went wrong, crashing the entire device. We're in Rhode Island, and it failed over to our DR site in Tennessee within 18 hours. Our users didn't notice because it happened on a Sunday. They had all their data when they returned to the office, and we reverted the following weekend. Without Zerto, some applications would've been down for days, if not weeks. 

Zerto has also improved our DR testing. In the past, we had to test over the weekend, but we can now do it during the work week without any outages. Our IT staff doesn't need to come in over the weekends, so it doesn't affect their personal lives. Zerto has reduced our DR testing time by about 50 hours. 

The interface is easy to use. It's not intuitive per se, but the average IT expert will have no problems using it. A non-IT person might have a little difficulty at the beginning.

I love Zerto's near synchronous replication because I can get up-to-the-minute data back in a disaster. This capability is essential because a disaster could cost the company money and even cause it to go out of business. We can sleep better at night knowing we can restore our systems in minutes.

Surgical blocking of unknown threats is a feature that's available on the cloud, but we're on-premises. However, it's certainly a feature I'd like to have, especially with all the malware and vulnerabilities. It's great to know that Zerto offers this capability, but we don't take advantage of it because we're an on-prem customer.

Zerto is too reliant on VMware's vCenter. It's tough to upgrade, move, or do anything related to virtual servers with vCenter.

Zerto is highly stable. We haven't experienced any noticeable bugs. We're sometimes too stable. Sometimes I want to upgrade my VMware ESX host, and I can't because they have not approved it on their matrix. They usually take about a month or two to accept it as a supported system, which is probably the industry norm or better, but I want it faster. 

I rate Zerto support 10 out of 10. Zerto's support team is knowledgeable and goes out of its way to help. Instead of just throwing KB articles at you, Zerto support walks you through the solution.

Positive

We previously restored everything from scratch using tape backups, but we had no software disaster recovery solution. It hasn't replaced our legacy backup solutions because we do not use Zerto as a backup. Our hardware backups are still online and working. 

We do not use Zerto as a backup solution. It is mainly for recovery. However, we use Zerto/Keepit for Office 365 backups. We still back up to tape and restore using Zerto. It has made the recovery around 20 times faster. 

Deploying Zerto was straightforward, and I did the job by myself.

We've seen a solid return with Zerto

Zerto costs more than most, but we negotiated a fair price. 

We have Veeam Backup and Replication, but we don't use it for disaster recovery. We also tried another solution for Office 365 backup. We prefer Zerto replication for the speed and support. 

I rate Zerto 10 out of 10. When implementing Zerto, you should consider your internet speed and the difference between the WAN connections at the sites you want to replicate. You need enough bandwidth to handle the volume. 

Originally, I was looking for a solution that allowed us to replicate our critical workloads to a cloud target and then pay a monthly fee to have it stored there. Then, if some kind of disaster happened, we would have the ability to instantiate or spin up those workloads in a cloud environment and provide access to our applications. That was the ask of the platform.

We are a manufacturing company, so our environment wouldn't be drastically affected by a webpage outage. However, depending on the applications that are affected, being a $15 billion dollar company, there could be a significant impact.

Zerto is very good in terms of providing continuous data protection. Now bear in mind the ability to do this in the cloud is newer to them than what they've always done traditionally on-premises. Along the way, there are some challenges when working with a cloud provider and having the connectivity methodology to replicate the VMs from on-premises to Azure, through the Zerto interface, and make sure that there's a healthy copy of Zerto in the cloud. For that mechanism, we spent several months working with Zerto, getting it dialed in to support what we needed to do. Otherwise, all of the other stuff that they've been known to do has worked flawlessly.

The interface is easy to use, although configuring the environment, and the infrastructure around it, wasn't so clear. The interface and its dashboard are very good and very nice to use. The interface is very telling in that it provides a lot of the telemetry that you need to validate that your backup is healthy, that it's current, and that it's recoverable.

A good example of how Zerto has improved the way our organization functions is that it has allowed us to decommission repurposed hardware that we were using to do the same type of DR activity. In the past, we would take old hardware and repurpose it as DR hardware, but along with that you have to have the administration expertise, and you have to worry about third-party support on that old hardware. It inevitably ends up breaking down or having problems, and by taking that out of the equation, with all of the DR going to the cloud, all that responsibility is now that of the cloud provider. It frees up our staff who had to babysit the old hardware. I think that, in and of itself, is enough reason to use Zerto.

We've determined that the ability to spin up workloads in Azure is the fastest that we've ever seen because it sits as a pre-converted VM. The speed to convert it and the speed to bring it back on-premises is compelling. It's faster than the other ways that we've tried or used in the past. On top of that, they employ their own compression and deduplication in terms of replicating to a target. As such, the whole capability is much more efficient than doing it the way we were doing it with Rubrik.

If we lost our data center and had to recover it, Zerto would save us a great deal of time. In our testing, we have found that recovering the entire data center would be completed within a day. In the past, it was going to take us close to a month. 

Using Zerto does not mean that we can reduce the number of people involved in a failover.  You still need to have expertise with VMware, Zerto, and Azure. It may not need to be as in-depth, and it's not as complicated as some other platforms might be. The person may not have to be such an expert because the platform is intuitive enough that somebody of that level can administer it. Ultimately, you still need a human body to do it.

The most valuable feature is the speed at which it can instantiate VMs. When I was doing the same thing with Rubrik, if I had 30 VMs on Azure and I wanted to bring them up live, it would take perhaps 24 hours. Having 1,000 VMs to do, it would be very time-consuming. With Zerto, I can bring up almost 1,000 VMs in an hour. This is what I really liked about Zerto, although it can do a lot of other things, as well.

The deduplication capabilities are good.

The onset of configuring an environment in the cloud is difficult and could be easier to do. When it's on-premises, it's a little bit easier because it's more of a controlled environment. It's a Windows operating system on a server and no matter what server you have, it's the same.

However, when you are putting it on AWS, that's a different procedure than installing it on Azure, which is a different procedure than installing it on GCP, if they even support it. I'm not sure that they do. In any event, they could do a better job in how to build that out, in terms of getting the product configured in a cloud environment.

There are some other things they can employ, in terms of the setup of the environment, that would make things a little less challenging. For example, you may need to have an Azure expert on the phone because you require some middleware expertise. This is something that Zerto knew about but maybe could have done a better job of implementing it in their product.

Their long-term retention product has room for improvement, although that is something that they are currently working on.

We have been with Zerto for approximately 10 years. We were probably one of the first adopters on the platform.

With respect to stability, on-premises, it's been so many years of having it there that it's baked in. It is stable, for sure. The cloud-based deployment is getting there. It's strong enough in terms of the uptime or resilience that we feel confident about getting behind a solution like this.

It is important to consider that any issues with instability could be related to other dependencies, like Azure or network connectivity or our on-premises environment. When you have a hybrid environment between on-premises and the cloud, it's never going to be as stable as a purely on-premises or purely cloud-based deployment. There are always going to be complications.

This is a scalable product. We tested scalability starting with 10 VMs and went right up to 100, and there was no difference. We are an SMB, on the larger side, so I wouldn't know what would happen if you tried to run it with 50,000 VMs. However, in an SMB-sized environment, it can definitely handle or scale to what we do, without any problems.

This is a global solution for us and there's a potential that usage will increase. Right now, it is protecting all of our criticals but not everything. What I mean is that some VMs in a DR scenario would not need to be spun up right away. Some could be done a month later and those particular ones would just fall into our normal recovery process from our backup. 

The backup side is what we're waiting on, or relying on, in terms of the next ask from Zerto. Barring that, we could literally use any other backup solution along with Zerto. I'm perfectly fine doing that but I think it would be nice to use Zerto's backup solution in conjunction with their DR, just because of the integration between the two.  

In general, the support is pretty good. They were just acquired by HP, and I'm not sure if that's going to make things better or worse. I've had experiences on both sides, but I think overall their support's been very good.

Zerto has not yet replaced any of our legacy backup products but it has replaced our DR solution. Prior to Zerto, we were using Rubrik as our DR solution. We switched to Zerto and it was a much better solution to accommodate what we wanted to do. The reason we switched had to do with support for VMware.

When we were using Rubrik, one of the problems we had was that if I instantiated the VM on Azure, it's running as an Azure VM, not as a VMware VM. This meant that if I needed to bring it back on-premises from Azure, I needed to convert it back to a VMware VM. It was running as a Hyper-V VM in Azure, but I needed an ESX version or a VMware version. At the time, Rubrik did not have a method to convert it back, so this left us stuck.

There are not a lot of other DR solutions like this on the market. There is Site Recovery Manager from VMware, and there is Zerto. After so many years of using it, I find that it is a very mature platform and I consider it easy to use. 

The initial setup is complex. It may be partly due to our understanding of Azure, which I would not put at an expert level. I would rate our skill at Azure between a neophyte and the mid-range in terms of understanding the connectivity points with it. In addition to that, we had to deal with a cloud service provider.

Essentially, we had to change things around, and I would not say that it was easy. It was difficult and definitely needed a third party to help get the product stood up.

Our deployment was completed within a couple of months of ending the PoC. Our PoC lasted between 30 and 60 days, over which time we were able to validate it. It took another 60 days to get it up and running after we got the green light to purchase it.

We're a multisite location, so the implementation strategy started with getting it baked at our corporate location and validating it. Then, build out an Azure footprint globally and then extend the product into those environments. 

We used a company called Insight to assist us with implementation. We had a previous history with one of their engineers, from previous work that we had done. We felt that he would be a good person to walk us through the implementation of Zerto. That, coupled with the fact that Zerto engineers were working with us as well. We had a mix of people supporting the project.

We have an infrastructure architect who's heading the project. He validates the environment, builds it out with the business partners and the vendor, helps figure out how it should be operationalized, configure it, and then it gets passed to our data protection group who has admins that will basically administrate the platform and it maintains itself.

Once the deployment is complete, maintaining the solution is a half-person effort. There are admins who have a background in data protection, backup products, as well as virtualization and understanding of VMware. A typical infrastructure administrator is capable of administering the platform.

Zerto has very much saved us money by enabling us to do DR in the cloud, rather than in our physical data center. To do what we want to do and have that same type of hardware, to be able to stand up on it and have that hardware at the ready with support and maintenance, would be huge compared to what I'm doing.

By the way, we are doing what is considered a poor man's DR. I'm not saying that I'm poor, but that's the term I place on it because most people have a replica of their hardware in another environment. One needs to pay for those hardware costs, even though it's not doing anything other than sitting there, just in case. Using Zerto, I don't have to pay for that hardware in the cloud.

All I pay for is storage, and that's much less than what the hardware cost would be. To run that environment with everything on there, just sitting, would cost a factor of ten to one.

I would use this ratio with that because the storage that it replicates to is not the fastest. There's no VMs, there's no compute or memory associated with replicating this, so all I'm paying for is the storage.

So in one case, I'm paying only for storage, and in the other case, I have to pay for storage and for hardware, compute, and connectivity. If you add all that up into what storage would be, I think it would be that storage is inexpensive, but compute added up with maintenance and everything, and networking connectivity between there and the soft costs and man-hours to support that environment, just to have it ready, I would say ten to one is probably a fair assessment.

When it comes to DR, there is no real return on investment. The return comes in the form of risk mitigation. If the question is whether I think that I spent the least amount of money to provide a resilient environment then I would answer yes. Without question.

If you are an IT person and you think that DR is too expensive then the cloud option from Zerto is good because anyone can afford to use it, as far as getting one or two of their criticals protected. The real value of the product is that if you didn't have any DR strategy, because you thought you couldn't afford it, you can at least have some form of DR, including your most critical apps up and running to support the business.

A lot of IT people roll the dice and they take chances that that day will never come. This way, they can save money. My advice is to look at the competition out there, such as VMware Site Recovery, and like anything else, try to leverage the best price you can.

There are no costs in addition to the standard licensing fees for the product itself. However, for the environment that it resides in, there certainly are. With Azure, for example, there are several additional costs including connectivity, storage, and the VPN. These ancillary costs are not trivial and you definitely have to spend some time understanding what they are and try to control them.

I looked at several solutions during the evaluation period. When Zerto came to the table, it was very good at doing backup. The other products could arguably instantiate and do the DR but they couldn't do everything that Zerto has been doing. Specifically, Zerto was handling that bubbling of the environment to be able to test it and ensure that there is no cross-contamination. That added feature, on top of the fact that it can do it so much faster than what Rubrik could, was the compelling reason why we looked there.

Along the way, I looked at Cohesity and Veeam and a few other vendors, but they didn't have an elegant solution or an elegant way of doing what I wanted to do, which is sending copies to an expensive cloud storage target, and then having the mechanism to instantiate them. The mechanism wasn't as elegant with some of those vendors.

We initially started with the on-premises version, where we replicated our global DR from the US to Taiwan. Zerto recently came out with a cloud-based, enterprise variant that gives you the ability to use it on-premises or in the cloud. With this, we've migrated our licenses to a cloud-based strategy for disaster recovery.

We are in the middle of evaluating their long-term retention, or long-term backup solution. It's very new to us. In the same way that Veeam, and Rubrik, and others were trying to get into Zerto's business, Zerto's now trying to get into their business as far as the backup solution.

I think it's much easier to do backup than what Zerto does for DR, so I don't think it will be very difficult for them to do table stakes back up, which is file retention for multiple targets, and that kind of thing.

Right now, I would say they're probably at the 70% mark as far as what I consider to be a success, but each version they release gets closer and closer to being a certifiable, good backup solution.

We have not had to recover our data after a ransomware attack but if our whole environment was encrypted, we have several ways to recover it. Zerto is the last resort for us but if we ever have to do that, I know that we can recover our environment in hours instead of days.

If that day ever occurs, which would be a very bad day if we had to recover at that level, then Zerto will be very helpful. We've done recoveries in the past where the on-premises restore was not healthy, and we've been able to recover them very fast. It isn't the onesie twosies that are compelling in terms of recovery because most vendors can provide that. It's the sheer volume of being able to restore so many at once that's the compelling factor for Zerto.

My advice for anybody who is implementing Zerto is to get a good cloud architect. Spend the time to build out your design, including your IP scheme, to support the feature sets and capabilities of the product. That is where the work needs to be done, more so than the Zerto products themselves. Zerto is pretty simple to get up and running but it's all the work ahead in the deployment or delivery that needs to be done. A good architect or cloud person will help with this.

The biggest lesson that I have learned from using Zerto is that it requires good planning but at the end of it, you'll have a reasonable disaster recovery solution. If you don't currently have one then this is certainly something that you should consider.

I would rate Zerto a ten out of ten.

We have multiple plans across the US. We use Zerto to transfer VMs from one plant to another plant, from east to west.

Zerto is a really great fallback software that gives us the redundancy we need.

Overall, the solution is really efficient. Zerto really helped us prevent the delay in bringing up the VM once it transfers because we wanted to ensure everything works.

Zerto's near-synchronous replication works great. We've had some issues before trying to synchronize VMs across long territory ranges, but Zerto did everything we needed it to do. Zerto's near-synchronous replication is extremely important to our organization. Our production line to uptime is almost 99.99%, so the near-synchronous replication really helps out.

We use SAP HANA with Zerto.

We use Zerto to protect VMs in our environment. The solution helps with recovery and ensures that we can transfer our VMs when we have a host failure. We have plants all over the US, and Zerto has really helped us keep everything running at almost 100% capacity.

Because of its near-synchronous uptime and recovery, Zerto's speed of recovery is ten times better than that of other disaster recovery solutions like Veeam and Commvault.

Compared to other solutions, Zerto's ease of use is pretty straightforward. I'm really excited to see how GreenLake has integrated Zerto and made it even more seamless.

It would be good if we could store a snapshot of the images coming through so that we can always go back and have a vision history.

I have been using Zerto for four years.

Zerto is pretty stable software, and it's always been up when we needed it.

I don't see any issues with the solution's scalability. We have 100 plants across the US and hundreds of other plants worldwide and have never had an issue adding any hosts or notes to the tool.

We deployed the solution through a consultant.

We have seen a return on investment with Zerto.

Zerto is really good software. It has all the features that I need. I love Zerto's integration with GreenLake, and now that we know more about it, we'll start utilizing it more. Zerto synchronized our VMs and delivered reliability by ensuring our hosts in different plants had a reliable backup.

Overall, I rate the solution an eight or nine out of ten.

It's used for general replication services and recovery. We're actually looking at its more integral use in DR in a business continuity role.

It integrates well with our environment, is very adaptable to our changing requirements, and is fairly easy for our team to use.

Zerto's near-synchronous replication is very efficient, very powerful, and very productive for us. It has helped us organize our recovery process a lot more, so it's led to process improvements.

Zerto is preparing us to do disaster recovery in the cloud rather than in a physical data center. But we are not there yet. 

We use it to support disaster recovery on Microsoft, but we are also considering AWS.

We use Zerto to protect our VMs. We're still redefining our RPOs due to Zerto's performance. We're going back and replacing our baseline.

When it comes to speed of recovery, we believe Zerto is above the rest that we know of.

I just learned about Zerto's vault capability, which we're going to learn more about. That will be very valuable to us. We get almost real-time replication services.

Those features are so valuable because we're always prepared to restore if we need to.

The vault feature will be very valuable to us, so that's one feature we'd like to see implemented. 

We're always looking for additional features and value from Zerto. Immutable replication services is one. I heard the vault will be totally protected from any outside influences, so that's another thing we're looking forward to. 

We're always looking to integrate better with our environment.

I have been using Zerto for roughly six years.

So far, it has been stable. No issues.

We haven't tested scalability yet, but we are sure that scalability shouldn't be an issue. We'll find out.

Good. Excellent. Now that Zerto is part of HP, we get greater support from HP's executive team.

We used a variety of solutions in the past. Zerto does the job of two or three of those previous solutions, so we were able to consolidate.

Zerto's team helped a lot. It was fairly straightforward and painless.

We have not come up with the metrics to determine the ROI yet, but we're working on it.

The pricing, licensing, and setup costs are fair at best. It's not the cheapest, but it works for us.

We did evaluate other solutions. Cohesity, Commvault Cloud and Rubrik were the two others we considered.

We liked the resiliency, usability, and use cases of Zerto more.

Overall, I would rate it around a seven out of ten. Once we understand the scalability, it could reach eight.

It's easy to install. Make sure your business requirements align with Zerto's capabilities. Others should study some of the use cases first before making a decision.

We implemented Zerto to improve our backup speeds and data recovery time. Zerto is deployed across multiple departments, and around 12 admins and analysts currently use it. 

Zerto has improved my organization in multiple ways, particularly its ability to scale. We have a massive environment that is undergoing cloud development because we are not a very old company, and we needed something that could help us. It's doing its job. Zerto supports multifocal scenarios across the cloud and on-premise.  

The solution has had a positive effect on our RPOs. The time is faster with Zerto. Another benefit is reduced downtime. Compared to what we used before, I'd estimate it reduces downtime by 25 percent. The solution has saved us time in a data recovery situation. I'm unsure how much, but it's a lot of time. Zerto has reduced our DR testing time by about 30 percent. 

Zerto has simplified compliance with industry regulations by including audit logs and official reporting to support regulatory compliance. It has also simplified our workload because it can do so many jobs.

The best feature of Zerto is the fast, automated backup and recovery. The data lift for applications is short, with minimal data loss. Zerto has improved my RTO because we can replicate and easily manage our data, which has positively impacted my company.

Zerto is easy to use if the installation is done properly. Its near-synchronous replication is wonderful, but I'm still learning how to use it. 

Zerto's analytics could be more detailed. The analytics report seems to be more difficult to read. 

I have used Zerto for 19 months.

I rate Zerton nine out of 10 for stability. It's highly stable. 

I rate Zerto seven out of 10 for scalability. 

I rate Zerto support eight out of 10. 

Positive

We previously used Microsoft Azure's backup option. It was a little bit cheaper, but Zerto's recovery is faster. It's a little bit more expensive but much quicker. 

I wasn't part of deploying Zerto, but I believe it was straightforward for them. It required a four-person team and took around two hours. After deployment, we occasionally experience some software bugs that must be investigated. 

We've seen a 10 percent ROI with Zerto compared to what we had before.

I rate Zerto two out of 10 for affordability. The licensing model is somewhat complex. Adding more flexible and less costly options would help.

I rate Zerto nine out of 10. I would recommend Zerto to others.
