We performed a comparison between VMware SRM (Site Recovery Manager) and Zerto based on our users’ reviews in four categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Zerto wins out in this competition. Its consistent sub-second response for RTO and RPO makes it one of the most responsive and fastest in the marketplace today. Users are able to easily run tests and change scenarios without any effect on an organization's production.
"VMware SRM's most valuable features are its convenience and its use of stretched clusters."
"It is easy to implement for my clients."
"The most valuable feature is the integration with our Nutanix environment."
"The installation and initial setup are straightforward."
"It made the DR process a lot faster and easier for recovery after we were familiar with the product operation."
"The product functionality is fairly high-quality."
"The solution is consistent."
"This SRM solution can improve your footprint within a data center."
"Zerto is scalable."
"It's also very much faster than any other migration or disaster recovery platform we have. I work with virtualization, mostly on VMware, and I must admit that Zerto is even better than VMware Site Recovery Manager. Zerto compresses the data and it works much faster."
"The orchestration and automation of the DR and how it replicates the VMs and then picks them up in the DR site have been most valuable."
"The most valuable feature is Zerto's ability to precopy data to a remote destination prior to the actual live migration period. That saves us a lot of time and has been very helpful. For example, if we had migrations occurring in waves over a period of several weeks with a VPG or VPG setup of approximately 50 VMs, that is multiple gigabytes of data, even terabytes in many cases. Having that data already copied on the evening of the migration saves considerable hours of time. It easily saves us four to six hours a night."
"The continuous data protection is great. We love it because I can see exactly how many seconds behind real-time we are, which is usually under 10 seconds. It keeps things up to date. We love the product."
"Zerto enables us to do sandboxing failovers. You can run tests on a production environment in a sandbox and spin up a copy of your actual production environment in a few hours. When you're done with it, you can click a couple of buttons, and it's all blown away. You don't need to worry about reverting changes or interfering with your on-prem production environments."
"The most valuable feature of this solution is the live migration."
"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... Migrating systems as a failover rollback or a system move are two of the functions that I like the most."
"In general, the drawbacks of VMware SRM, where improvements can be made, stem from the fact that it is an expensive and complex product."
"The interface is not easy to use and can be made more user-friendly."
"The technical support is not quick enough to respond when a user tries to contact them."
"You need a lot of knowledge to work with the interface because it is not really easy to use, and it would be great if the dashboard were simplified."
"We've had configuration issues on occasion. We start to fail over, and then we have to call it off because the configuration is not right, or the data stores aren't configured correctly in the secondary data center. Oftentimes, it is just the experience level of the team, and we have to bring in the vendor to help and validate our configuration."
"If you have a failover case, you need to work on it manually. It would be helpful if this could be automated. It would simplify things."
"The product's dashboard is an area of concern where improvements are required."
"The solution is on the expensive side."
"It is crucial for Zerto to collaborate closely with VMware in order to promptly test updates."
"Overall, Zerto is doing a very good job. We have experienced a few downtimes on networking. Most of the time, they come up with a solution immediately to sort out any challenge that may affect data flow or data migration. It does not happen frequently. We might experience it once in two months, but when we face any downtime, it does not impact the data."
"If I had to pick anything, it would be the documentation for upgrades. They need to make it easier for users to do upgrades without having to contact support, by providing better documentation for that."
"The limitation with Zerto is that you're required to have one Zerto Manager per virtual center, and this means that you're only able to replicate one way. Technical support for this product was fantastic, before they were acquired by HP. You're now able to tell that the company is becoming too big, in terms of the support they provide."
"The only thing we've noticed that needs improvement is the backend cleanup within VMware. There are some little issues there. I would like to see tighter integration with Vmware... orphan data is an issue within VMware. It doesn't clean up properly when you're moving stuff around."
"There should be more comprehensive cyber recovery capabilities."
"In general, the solution is pretty good, but because it is geared toward simplicity, sometimes, when things go wrong, the answer is not very detailed so that things can be solved quickly. If things do go wrong, it does require a little bit deeper troubleshooting to resolve the issues. That's the only area where improvement could occur. There should be a little bit more details about if things go wrong, how to remedy them."
"A slight disadvantage of Zerto is that it requires the Windows Server operating system as the base OS. Over time, I would like to see more offerings in that regard. There should be more deployment options other than just the Windows operating system."
