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.
"The most valuable feature is the integration with our Nutanix environment."
"The solution is scalable."
"Virtual Machine Recovery during DR situation, with automation and easy to use menus and options."
"It's easy to use and the interface is quite simple."
"The product functionality is fairly high-quality."
"If you want to do failover, it works without any problem."
"I would rate the ease of setting up and configuring my recovery plan in VMware SRM, a ten out of ten, with ten being the easiest."
"The most valuable features are the disaster recovery and testing."
"The ease of use and simplicity in moving things without having to do a cross-v set of V-motions has been most valuable. It saves time and effort and it eliminates mistakes."
"The most valuable feature of Zerto for us is its DR capability."
"The solution's continuous protection is the best on the market. The ability to do the split-write, without any interruption to the production server, and the ability to roll back to any point in time you desire, are two really key features."
"We had a disaster recovery four or five years ago. I can't remember what happened, but I believe something crashed in our data center, like a power outage. We did a failover of our network using Zerto from production to disaster recovery. We successfully completed the failover process in three or four hours without issue. The data was current, and the application owners could access their data and continue working while the issue was resolved."
"The most important feature is that the recovery point (RPO) is less than one minute. The is really good for our customers, as they can keep their data loss to a minimum."
"Journaling allows us to leverage Zerto's journal for sub-minute recoveries, instead of having to wait for the storage array to replicate."
"The continuation to the public cloud has been especially helpful where I can pretty much work with things like hosts and clusters as part of the data center."
"Its ease of use is most valuable. The online documentation is very clear and helpful. We are able to solve a lot of problems on our own without having to contact support."
"It has a lot of dependencies on VMware infrastructure, and testing can be complex. Testing often requires extensive approval at the organizational level."
"There needs to be better stability during heavy capacity in future releases."
"Technical support can take some time to respond."
"The administration guides can be complicated and difficult to use, so it would be helpful if it was made easier."
"VMware SRM's platform agnostics should support on-cloud usage as well."
"The product's dashboard is an area of concern where improvements are required."
"The technical support is not very good and needs to make an effort to improve."
"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."
"We have had some issues with trying to get certain parts of the backup or restore functionality to work."
"The improvement that I would like to see is a little bit easier product knowledge, things like that. It's getting a lot better than it was before because it's not as old of a product as Cisco, but if you look for something like Cisco routing and networking, you'll find millions of articles out there and it's everywhere."
"It would be difficult to do, but I would love it if Zerto handled some of the scripting and things necessary to do a recovery. For example, it would be helpful if the solution could update the DNS to point to a new location. It would be nice to automate some of those tasks that you have to do to recover a VM and they were kinda out-of-the-box point-and-click things rather than things that required you to write a script."
"The only issue that I observed was that depending on the number of virtual machines that are being replicated, you will have to provision the appropriate bandwidth for the link that the replicated systems will traverse."
"When we are trying to upgrade any virtual machines, we have to stop the virtual machines that have been replicated in Zerto and then upgrade or update to the virtual machines onsite. Instead of having to do it manually, there should be some way of automating that particular function."
"I would like to see improvement on the Zerto Virtual Replication appliances, so that they are a little bit more streamlined as opposed to now where they just span multiple ZVR appliances like there were gremlins... as this thing grows it just spawns unlimited numbers of additional ZVR appliances and you end up with a bunch so that you can't really tell which is which."
"We'd like to be able to migrate data without its operating system or any other functionality and without having to go through a virtual machine or server."
"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."
