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's tech support gets a nine-out-of-ten. They are responsive and get you a useful reply."
"VMware SRM's most valuable features are its convenience and its use of stretched clusters."
"It's very reliable. The solution is stable."
"The solution is scalable."
"The solution is strong when it comes to protection and analytics, with the latter being added later on."
"VMware SRM is very effective between two sites with identical twin storage, you can have synchronization between the two sites."
"My impression is that the initial setup process is relatively straightforward."
"The most valuable feature of the solution is the automatic recovery of the virtual machine if it goes down."
"The most valuable tool is the dashboard, which allows us to immediately check the DLP status, replication data, and all other data needed to have cleaner and immediate control of the situation."
"The ability to fully test your entire environment without actually performing a failover is invaluable."
"We work a lot with customers that need disaster recovery and the best possible migration approaches, and Zerto helps them minimize the amount of effort it takes to finish their upgrades or migrations."
"The feature I've found most valuable so far has been the ability to migrate the VMs from Hyper-V and Citrix Hypervisor. It's made our migration seamless. In the beginning, we were looking at freeware tools, and it was just a massive headache. Zerto solved a lot of the roadblocks that we'd run into in the past."
"VMware VM replication over narrow WAN bandwidth."
"Consistency Groups: If you replicate groups of VMs, then during failover, all of the VMs in groups are failed over to the exact same point in time."
"There are several valuable features because of the way we use it. The backup and restore features are definitely indispensable."
"The real-time replication of data is the most valuable feature. It is a vast improvement in scheduled daily backups. Real-time data is streamed to the offsite data center, which allows us to restore our mission-critical applications up to 10 seconds from when the last changes were made in our system. If we enter a sales order or enter any kind of information in our ERP application it is replicated within 10 seconds to the offsite location."
"In my view, if VMware comes up with an appliance-based solution like vCenter Server (which was also Windows-based), it will be much easier for deployment. I"
"Technical support can take some time to respond."
"Currently, there is a limitation of consolidating only 15 sites per SRM."
"SRM has to be installed on two separate data centers, so both have to be coordinated very well, which becomes complicated when configuring the software for disaster recovery."
"The technical support is not quick enough to respond when a user tries to contact them."
"The back sites sometimes are very, very complicated."
"This product is not appropriate for those moving to a broader cloud footprint."
"We would like the patching management function of this product to be improved."
"If the log was more detailed and more user-friendly, we wouldn't have to make the calls to the support to try and figure out where the problem lies."
"The replication appliances tend to have issues when they recover from being powered off when a host is in maintenance mode. Sometimes you have to do a manual task where you go in and detach hard disks that are no longer in use, to get the replication appliances to power back on. There are some improvements to be made around the way those recover."
"The full site recovery is not up to SRM standards."
"Zerto could add text alerts if there are critical problems and alerts if changes affect our replication."
"When we do failover and failback, it doesn't maintain some of the settings that it should and I don't really understand why that happens."
"The onset of configuring an environment in the cloud is difficult and could be easier to do."
"We would like the LTR function to be able to retain the past 12 months."
"I don't feel like we're a big enough customer to warrant being called every week or every month but it would be good to get a little bit more contact with a salesperson or engineer group."
