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.
"In terms of resiliency, the most valuable aspect of SRM has been its effectiveness."
"It is a very stable solution...I was involved in VMware SRM's deployment phase two years ago, and it was an easy process."
"It's very reliable. The solution is stable."
"This SRM solution can improve your footprint within a data center."
"My impression is that the initial setup process is relatively straightforward."
"VMware's tech support gets a nine-out-of-ten. They are responsive and get you a useful reply."
"VMware is one of the best products in the industry when it comes to virtualization."
"The most valuable feature is the integration with our Nutanix environment."
"We've never had any major headaches with the virtual-protection groups. They seem to work exactly as they should. If there's ever an issue with replication, we know right away, so it's all been very reliable."
"I really like how you can test the failover as often as you need."
"With Zerto, we were able to replicate our virtual servers to a remote DR site across a WAN connection."
"There are two things that are keeping us with the solution: 1. It does a very good job of keeping the data in sync at all times. 2. In the event of a failover or in the event of a contingency, we are able to retrieve the data very quickly without any issues."
"I would give it an eight out of 10, if not a nine out of 10, when it comes to ease of use."
"I found the very easy VPG setup, the easy recovery, and failover testing to be the most valuable features."
"The Zerto university for training staff is very useful."
"The most important features are the simplicity of recovery and the wider capabilities and feature sets than VMware SRM has."
"Sometimes it can cause a bit of downtime during switchovers."
"The configuration process could be improved."
"We have had an issue when some customers have traditional designs and sites. For example, on one another site, they are using hyper-converged, using VMware, or Nutanix. We have a problem with the synchronization between the storage for site to site. This is the main issue. We are adding some other tools to support the synchronization to allow the movement of the workload from site to site easily."
"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 administration guides can be complicated and difficult to use, so it would be helpful if it was made easier."
"Technical support can take some time to respond."
"The product's dashboard is an area of concern where improvements are required."
"The primary site lacks adequate equipment, such as power backup and cooling, which can lead to downtime during issues like power outages or overheating."
"When building out a VPG and doing the machine types within Azure, they were not coming across correctly. It would say it had a CPU and memory of a specific type, but it was not accurate... It was a bug and they were working on it."
"We do have some sites that are very low-bandwidth sites. Zerto is able to set throttling in the solution, but the throttling is set at a site-wide level. In those instances that have very low bandwidth, I can't reduce the throttling on that site. It would be nice if there were a way to control the throttling by the protection group for a specific workload."
"Their data backup and restore have some ways to go."
"Right now, if you have an error, it creates a link that takes you to a website to review information about the problem. It would be nice if Zerto could give you information within the app instead of referring you to a web application."
"The VPG model causes us a bit of concern. We are considering using Zerto to replace Site Recovery Manager. Site Recovery Manager is very easy when we have entire data scores being replicated. We don't have to make any decisions when it comes to groupings. It is all covered. If we move to Zerto, which we are considering, we will have to work much closer with the applications teams to develop the VPG configuration and determine how the VMs will be grouped. It will be a lot more overhead for us to go that route."
"There are a lot of features that it has that we don't use since we are on prem."
"It took some time to get to know the solution in general, and exactly what functions each of the features is used for."
"If I were to nitpick, I would say that I wish I had a better account manager. Our sales guy has changed a couple of times. I would like a little more responsiveness from our account manager. I've had a couple of issues where getting in touch with him has been a little difficult, and I end up just going around him and dealing with support and support has handled it right away."
