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 is very effective between two sites with identical twin storage, you can have synchronization between the two sites."
"The replication is a key feature."
"It's very reliable. The solution is stable."
"Its capability to schedule, write and configure the recovery and scheduled steps, such that you don't have to come in and start manually trying to recover the entire machine. You just push a button to recover the VMware and everything is done."
"VMware is one of the best products in the industry when it comes to virtualization."
"VMware SRM is a very nice tool for disaster recovery for virtual environments."
"VMware SRM replicates the VM from one site to another, and it helps us orchestrate the powering of VMs and DR when the DC goes down."
"The solution is very flexible."
"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 biggest benefit is the application-consistent disaster recovery functionality."
"It reduced the time for DR tests from the infrastructure side. Being able to get our work done in a matter of a couple of minutes so the app teams can get to work and can do their testing has been significant."
"We are moving to a new data center. There are several VMs that we have to move over there that have RDM disks or SQL clusters. Those are the hardest things to move at this point in time, but now that I have the setup and it is ready to go, all we have to do is just flip the switch and get everything over where they are supposed to be. It is going to be a lifesaver for me. It will save me a whole lot of time in putting things back together."
"It has enabled DR protection for virtual appliances with minimal administrator time."
"The near-synchronous replication is one of the primary reasons we're using Zerto because we have recovery intervals of sub-five seconds. On a scale of 10, where 10 is "very important", this feature is a 10."
"The replication feature where it constantly replicates and sees that data is always in sync is valuable."
"Four years ago when we did a PoC between two other vendors and Zerto, there were two features of Zerto that sold it, hands-down. One was the ease of creating protection groups, the ease with which our engineers could create protection, add virtual machines into the Zerto product, and get them under DR protection."
"The technical support is not quick enough to respond when a user tries to contact them."
"There needs to be better stability during heavy capacity in future releases."
"The solution must provide better integration with third-party vendors."
"The configuration process could be improved."
"The initial setup of VMware SRM isn't straightforward because many customizations are required since it helps in the recovery of your IT environment."
"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."
"The two vCenters have to be synchronized, which sometimes gives us problems because Keberos does not tolerate more than five minutes in time difference."
"The biggest issue for us is that this product does not have any demo for customers."
"Right now, our production environment runs on-premises, and we have a DR copy of everything that we run in production. However, our development runs on that hardware. In the case of a DR event, we would need to shut down development and bring up our secondary copy of production. We're hoping that Zerto is going to be the tool to help us do that."
"Zerto added the backup feature, but it's not quite up to speed yet when you compare it with the backup capabilities of other solutions out there."
"There needs to be more flexibility in the licensing."
"The time between releases is too long. Zerto doesn't seem to really keep up with the products with which they need to be compatible. For instance, the 9.5 updates 3 took about 90 days to come out after the latest version of vCenter 7.0 update 3 was released."
"The technical support has room for improvement."
"Zerto needs to improve its documentation."
"It would be nice if Zerto offered OVFs, which are custom-built VMs that you can install on your virtualized environment. At the moment, I have the Zerto sitting on two custom-built Windows servers, which creates a lot of overhead. I'm waiting for them to create an OVF file, which is a built and hardened version of their Zerto server that I can just install wherever with a couple of mouse clicks."
"The tech support on my latest issue wasn't so great. I had to figure a lot of stuff out myself. It could be that I had a Level 1 tech who was new or something, but it seemed like the tech was spitballing, which does not help me."
