Zerto Reviews

We use it for disaster recovery purposes. Since Zerto offers a near recovery point objective recovery, we utilize it to validate our servers from one location to another.

By implementing Zerto, we wanted to ensure that in the event of a disaster or ransomware, we are able to recover and not lose any significant amount of data.

Zerto is very easy to use. Installation is about half an hour, and then it starts protecting the data and VMs. It is not very cumbersome. The UI is built very well. It is fairly self-explanatory. To be able to stand up a product you have never seen in half an hour and get it functioning and protecting speaks to how good the UI and workflow are.

Zerto has near-synchronous replication. As a change is made on site A, it gets copied across the network to site B. We are five or six seconds behind production. If I have a heavily used system and I use traditional backups, I could be anywhere from 5 minutes to 23 hours behind. With Zerto, I am single-digit seconds behind. That works well for us.

Our disaster recovery test, which used to span an entire week, now takes two days. We used to recover our servers in the first two or three days with a backup product and then test for two days before tearing it all down. Now, we spend half a day on new servers and ensuring things work with networking, etc. We test the next day, and we are done in two days. Across the entire company, we are able to save significant man-hours by shortening the test from a week to two days. We are now doing smaller tests once a month and larger tests once a year.

Zerto has reduced our DR testing time by 60% to 70%. We are also able to do more disaster recovery testing. Previously, we were doing it once a year, whereas now, we are doing smaller tests once a month and our large tests once a year.

In recovery point objectives, we are single-digit seconds behind. In terms of RTOs, I can recover 350 VMs in 30 minutes. It takes less than several seconds to restore a single VM. From days to 30 minutes for 350 compared to 100 VMs is an incredible time-saving in terms of RTOs and RPOs for us.

Our use case is disaster recovery replication.

We primarily use it for the automation orchestration for disaster recovery. We were looking for a solution that could do individual virtual machine replication failover and failback, and Zerto provided that.

We conduct DR tests biannually. With Zerto, our DR tests go much faster. Orchestration is much better. Previously, these events took two to four hours, and they are now down to under fifteen minutes. The speed of the DR test is better. Accuracy is better. Everything is faster all around. It has saved 15% to 25% of time.

We use Zerto to help protect VMs in our environment. Right now, our recovery is in seconds of several critical VMs. There is more than a 95% reduction in RPO and RTO time. It has been significant.

We also have more accuracy. There is about a 50% improvement. Human error has decreased by 50% as well. Things seem to be going a little bit better. We are working on more scripting and automation so that we get to the eventual goal of push-button. Right now, engineers have to push buttons within the Zerto console, but we are trying to work on full automation orchestration so that we can get it down to five minutes from fifteen minutes.

Zerto has saved downtime by 25%. From a quantification standpoint, there are 15% to 20% cost savings.

We are using anti-ransomware approaches on Zerto as well as data protection backup and primary storage, so at this time, Zerto has not saved time in a data recovery situation due to ransomware or other causes, but we are investigating use cases for anti-ransomware recovery.

Zerto is quite central to our IT resiliency strategy. Several of our big customers require it. DR is a service that we sell, so it is pretty important for us.

We primarily use Zerto as a disaster recovery tool to handle data transfer between virtual machines. Currently, Zerto is implemented on-premises, as 90 percent of our services reside there. However, we plan to migrate some services to the cloud and utilize Zerto's migration capabilities to move VMs directly from our on-premises environment to the cloud. This is a crucial feature for us, as our virtualization technique relies heavily on VMware, and Zerto allows for straightforward migration of critical VMs to the cloud.

Our multi-campus university faced challenges delivering services hosted in a single location to geographically dispersed users. The extensive data volume and risk of outages due to disasters led us to implement a Disaster Recovery and Continuity setup. This involves hosting primary services in one data center and maintaining a disaster recovery site in another. Zerto's replication technology allows us to continuously update data at the DR site, ensuring data currency and the ability to roll back to a stable version quickly.

Zerto is straightforward to implement because it only requires the installation of an agent on the VMs designated for migration. A service, typically a VM, must also be deployed at the disaster recovery location. This entire process is simple and can be completed within three days.

Zerto's near-synchronous replication occurs every minute, allowing for highly granular recovery points. This means that even if interruptions or malware disruptions occur within that minute, Zerto can restore to the last known good state, effectively recovering the entire setup to the latest backup. This capability ensures high data security and minimizes potential data loss.

One of the main benefits of implementing Zerto is its data compression, which significantly reduces the load on our IPsec VPN. Zerto compresses data by 80 percent before transmitting it across the VPN, minimizing the data transferred between geographically dispersed locations. This compression and subsequent decompression at the destination alleviate the strain on the VPN, preventing overload and ensuring efficient data synchronization.

Zerto simplifies malware protection by integrating it into its disaster recovery and synchronization features. This comprehensive approach eliminates the need for separate antivirus setups in virtual machines and applications. It streamlines our security measures and removes the need for additional software or solutions, resulting in an excellent return on investment.

Zerto's single-click recovery solution offers exceptional recovery speed. Through the user interface, a single click allows for a complete restoration from the most recent backup within two to three minutes, enabling rapid recovery and minimal downtime.

Zerto's Recovery Time Objective is excellent. In the past, if a virtual machine crashed, we would recover it from a snapshot, which could take one to two hours. With Zerto, the recovery process takes only five minutes, and users are typically unaware of any disruption. This allows us to restore everything quickly and efficiently.

Zerto has significantly reduced our downtime. When malware affects our data, Zerto immediately notifies us and helps us protect other applications, even those not yet implemented with Zerto. By monitoring these applications, we can quickly identify and address any potential malware spread, minimizing downtime across our systems.

Zerto significantly reduces downtime and associated costs during disruptions. Our services are unified, so in the event of a disruption without Zerto, even a half-day disruption would necessitate offline procedures. This would lead to increased manpower, service delays, and substantial financial losses due to interrupted admissions and other critical processes. By unifying service processes, Zerto minimizes the impact of outages.

Zerto streamlines our disaster recovery testing across multiple locations by enabling efficient failover testing without disrupting live services. Traditionally, DR testing required downtime of critical systems, but Zerto's replication and failover capabilities allow us to test in parallel with live operations. This non-disruptive approach ensures continuous service availability while validating our DR plan, even in scenarios like malware attacks, by creating a separate testing environment that mirrors the live setup. This comprehensive testing provides confidence in our ability to handle real-world incidents effectively. This saves us over 60 percent of the time.

Zerto streamlines system administration tasks by automating many processes, thereby reducing the workload for multiple administrators. This allows them to focus on other university services that require attention and effectively reallocate support resources from automated tasks to those requiring more dedicated management.

Zerto is used exclusively for our critical services, providing up to a 70 percent improvement in our IT resilience.

Our systems are primarily Windows-based, but a big portion of the organization also runs on AS/400. About 40% of our systems are AS/400.

We use Zerto to replicate data from a primary data center to a secondary data center. In the previous incarnation, we used Zerto to replicate our secondary data center and also Azure because we were looking to start moving more and more things to Azure. We were considering Azure to have someplace where we could run some of our critical systems in the event we did not have much capacity in the secondary data center or it just made sense to leverage Azure for a particular application.

Zerto’s near-synchronous replication works very well. Most of the time, our systems are running about three seconds behind the primary, which is something most people are not going to complain about. It also has the ability to take you back to a point in time where everything is in sync. You can start from that point and maybe lose a couple of transactions as opposed to a typical backup environment where you could lose hundreds of transactions as a result of an outage. It can help revert systems to a specific point in time, providing continuity where data loss is minimal compared to traditional backup solutions. 

We saw the benefits of Zerto right away. It gave us the confidence that if something happened, we would be able to restore our data. A notable benefit is the ability to conduct failover testing in a virtual environment. We can confirm operations without affecting external users. The software audits its processes, offering detailed reports.

Zerto has also continued to upgrade features, including Secure Vault and tools for immutability, enhancing ransomware protection, but a hardware change is required to fully benefit from Zerto's ransomware solutions. We have to go with their hardware versus what we are running. We can take advantage of some of the things that they do to help with ransomware, but we cannot get all the way there without switching the hardware.

We use Zerto to protect virtual machines. Our RPOs have moved. Prior to Zerto, and at different places, we have used other solutions such as Pure Storage or IBM replication solutions. Most of these solutions tend to have an RPO of minutes or more, whereas, with Zerto, we are looking at an RPO of less than ten seconds or something like that. That was one of the big differences we saw. It is also an integrated solution. You move the entire environment as opposed to some of the other environments where you connect to the storage, and then the storage is doing the replication. At the point at which something fails, you have to reconnect servers back up to the right hardware before you can get started in recovery. With Zerto, your recovery time goes down, and your RPO becomes much better.

The recovery time or RTO is much better with Zerto if you have the right bandwidth and other things. If you have an issue with latency or bandwidth, you may see those RTO numbers go up a little bit. Generally, RTOs are much better.

We have not seen Zerto reducing downtime in any situation. We have not necessarily seen an improvement there.

In terms of time savings in a data recovery situation, we went through a ransomware event at the last company. I have seen Zerto help from a ransomware perspective because one of the things that Zerto does is it maintains a whole bunch of snapshots as it goes along. In a ransomware situation, you can go back to the time before you were hit by the ransomware. You can go back in time and recover those servers. You can scan them to make sure they do not have whatever malware was installed for the ransomware, and then you can recover.

Zerto has had a huge impact on our resiliency strategy. It allows us to be able to leverage our secondary data center for a major event. It also frees us up to do more things in the local environment such as leveraging SQL Always On.

Zerto has not helped us to reduce overall DR testing. We would like to do more testing with Zerto, but some folks are very comfortable with just Zerto saying everything is okay. On the other hand, Zerto has been able to help us increase our testing where we could not do it before. That does not mean that we are satisfied with where it is. We would like to do more with it.

I use Zerto for backup and restore.

With both Veeam and vCenter, the restoration process took a considerable amount of time. Zerto bragged about how their restoration was much faster, and it was true. It seemed unrealistically faster when they described and said that they could restore a VM within minutes. With vCenter and Veeam, when we restore a VM, depending on the size of the VM, it can take hours. Zerto proved true, and we have tested it numerous times now. We have done restorations via Zerto, and it truly does a full restoration of a VM within minutes. That was the problem we needed to solve, and they provided the solution. We are very pleased.

We are able to do a restoration so quickly because it backs up in near real-time. Of course, nothing is going to be in real-time, but it is as near real-time as possible. Instead of copying a larger amount of data, it is able to copy just delta data which is in a compressed form so that replication is more frequent. If we need to do a restoration, we will be missing less data.

Its interface is like any enterprise-grade utility. It is complex and not easy to use, but it is learnable.

We were able to see its benefits after some time. That was mostly because we did not have a good opportunity to test it in production. The initial onboarding came with an opportunity for us to do a test backup and restoration, but that was test data. You find the true value of this platform when you use it in a production environment where a stakeholder is involved and there is data that if you do not restore will lead to problems.

We use Zerto to help protect VMs in our environment. The restoration time is in minutes versus hours. That goes a long way towards our RPO. With our previous platform, it took two hours, and with this platform, it takes five minutes. It has also had a positive effect on our RTOs.

Zerto has helped us to reduce downtime with a restoration time of five minutes versus two hours.

We have not had to use it for restoration because of ransomware. We were using a couple of VMs to test migration to a new database. While testing that migration, we caused damage to the VMs. We then used Zerto to restore them prior to that damage, and it was fantastic. The restoration was quick and effective, and we were back in production in minutes versus hours.

Zerto has reduced the time spent on DR testing but we still do the same number of DR tests throughout the year to make sure. It just takes a lot less time.

Zerto has improved our confidence tremendously, and it has reduced the RPO of any potential restoration needs.

It is part of a new deployment. We have a large deployment for the public sector in the UK, and we are using Zerto to enable disaster recovery by replicating data. This allows us to have a very low recovery point objective for that data.

Zerto is easy to use and fairly straightforward to set up. It reliably keeps the data in sync which is all that we can ask of it. It does what it says on the tin, and that takes away any worries. We know that we will be able to recover as we are contracted to do.

Having Zerto in place takes a headache off my plate. I do not have to worry about it. I check it, or I have my team check that it is up to date and synchronizing. All they have to do is log on, have a look, and confirm that we are okay and have green lights across the board. It is very easy to understand the interface.

It is one of those things that sits and does its job and does it well. Therefore, we do not have to worry about it. That is the biggest thing. We have peace of mind at the end of the day.

Zerto's near-synchronous replication is very important. We run an application in the SaaS model for our customers. Our customers sign into our application. It is a purchasing application called PECOS. We do purchasing and inventory management. They sign in to our systems and do their business. We have to ensure that the systems are highly available. In the event of a disaster, we can bring them up with a minimum loss of data. That is where Zerto comes in.

We use Zerto to help protect VMs in our environment. Our recovery point objective by contract is within four hours, but practically, it is within five minutes. Zerto is very effective. If I look at it during the day, I generally see that we are within nine to ten seconds. It is a very good thing to see.

Zerto recovery is a lot faster than recovery from a tape or a digital backup. We did a test against the old RecoverPoint and found Zerto to be faster. We also do disaster recovery tests. I have a full disaster recovery test coming up at the end of the month. We expect to be able to bring up the entire environment for our customer within 45 minutes, which is very good.

Zerto has not reduced our downtime, but it has made us feel a lot better. In the event we have downtime, we have some protection there.

Zerto has not saved us time in a real-time data recovery situation. In our rehearsals, it definitely has saved time. Hopefully, our systems have been built reliably enough that we would not have to use it for one. It is just an insurance system.

We still do DR testing. We have noticed a speed improvement in our DR testing. It is slightly faster, but we still have to do DR testing. As with any system, you have to make sure it works.

Zerto has given us confidence in our IT resilience strategy. We had similar strategies in place with the previous infrastructure. We completely renewed our entire infrastructure and replaced it with HPE backend and SAN. Zerto is the recovery solution. We have a lot of confidence that it will work if called upon.

We use Zerto for disaster recovery between our private data centers.

Near-synchronous replication is the primary reason we chose Zerto, as nobody else is able to meet the same replication times. We have some special contracts, so Zerto is the only one that can meet those contractual requirements.

Zerto has had a significant impact on our RTOs. We have probably reduced our RTOs by 70% to 80%. Previously, we relied on manually replicated backups that we had to restore from, resulting in significant RTO compared to Zerto.

We use Zerto to help protect virtual machines in our environment. When it comes to recovery, if other solutions take five minutes, with Zerto, we can usually get them up in under a minute. Our RTOs are much quicker on Zerto. It is probably 20 seconds on Zerto versus an hour with others.

We have had multiple live disaster recovery events where Zerto saved us a lot of downtime. We have not had any ransomware situations, but it has saved us time in generalized data recovery.

Zerto has helped reduce DR testing. For the customers for whom we use Zerto for disaster recovery, we usually do DR testing once a month, and it takes us probably two minutes to run those DR tests. With other solutions that we use for our wider customer base, it takes us about two days to go through all of our DR testing.

Zerto has had a significant impact on our IT resiliency strategy. The tier-one customers that we use Zerto for have very strict requirements for their disaster recovery capabilities, and Zerto is able to meet those contractual obligations pretty easily.

We were able to realize its benefits immediately after the deployment.

We are using Zerto as a DR solution. We also utilize Zerto when we have to migrate any servers from one location to another.

Previously, we were using VMware Site Recovery Manager, and we were not happy with the services we received. There were lots of issues. Since implementing Zerto, we have been happy. We are not seeing any issues with the services. Zerto's support is also excellent. If we encounter any issues, we open a ticket, and they are available all the time.

When we implemented Zerto, we were not sure how things would work. We have a DR test or maintenance window every quarter. During the first window, when we did the DR implementation through Zerto, we found it to be very helpful. Previously, we used to manually take screenshots for DR evidence, whereas now, we can generate a report from Zerto. After the DR, it tells everything in detail such as when a VM was moved, what the procedure was, and how much time it took to consolidate from the primary site to the DR site.

When we had an issue with a legacy application over the weekend and users reported it on Monday, we had to revert the VM to a snapshot from eight hours prior. We could do that easily. This is an excellent feature. Zerto allows us to select a custom recovery time. For instance, if no one checked the server yesterday because it was a holiday and we needed to restore the VM to the day before yesterday, we could do that quickly. Zerto helps address downtime situations effectively.

Zerto has reduced the DR testing time. Previously, it took three to four hours, including app testing, but now it gets completed in one hour. 

Zerto is excellent. It is the primary and only solution we are using in our organization.
