We compared Zerto and NetApp Cloud Volumes ONTAP across several parameters based on our users' reviews. After reading the collected data, you can find our conclusion below:
Comparison Results: Zerto is praised for its easy setup and user-friendly interface, as well as its continuous data protection and quick recovery features. NetApp Cloud Volumes ONTAP offers strong integration capabilities and comprehensive storage management, but some users find it expensive. Both products have mixed reviews for customer service and support.
"Its scalability is very good."
"CVO gives us the ability to access data as quickly as possible, which is critical because of the mission set we handle. Some things cannot wait. For example, we tried having the data in the cloud itself, but it took too long for us to retrieve it from cold or deep storage. If we have it ONTAP or on-prem, it's so much easier to pull it within minutes."
"The most valuable features of this solution are SnapShot, FlexClone, and deduplication."
"This solution has made everything easier to do."
"One of the most valuable features is its similarity to the physical app, which makes it familiar. It's almost identical to a real NetApp, which means you can run all of the associated NetApp processes and services with it. Otherwise, we would definitely have to deploy some hardware on a site somewhere, which could be a challenge in terms of CapEx."
"Unified Manager, System Manager, and Cloud Manager are all GUI-based. It's easy for somebody who has not been exposed to this for years to pick it up and work with it."
"The Cloud Manager application that's on the NetApp cloud site is easy to use. You can set up and schedule replications from there, so you don't have to go into the ONTAP system. Another feature we've recently started using is the scheduled power off. We started with one client and have been slowly implementing it with others. We can cut costs by not having the VM run all the time. It's only on when it's doing replication, but it powers off after."
"Multiprotocol is the most valuable because Amazon was not able to provide us with access to the same data from Linux and from Windows clients. That was our value proposition for CVO, Cloud Volumes ONTAP."
"RPO time for the copied-off VMs appears to be quite short."
"Using Zerto for the migration was incredibly valuable, enabling us to save tremendous amounts of time."
"The granularity enables us to failover specific workloads instead of an all-or-nothing type of scenario, where you have to move your entire IP block and your data center, or you have to move large chunks of VMs. Those situations also make it prohibitive to test effectively."
"With Zerto, we were able to replicate our virtual servers to a remote DR site across a WAN connection."
"Zerto's user-friendliness is valuable."
"The fact that we are able to test the failover of live systems during regular hours is invaluable to our organization."
"Journaling allows us to leverage Zerto's journal for sub-minute recoveries, instead of having to wait for the storage array to replicate."
"The file restoration is very helpful. They've improved it over the years to make it a lot more user-friendly and easy to do, which I appreciate. So, we use that quite a bit. The failover process is quite simple and intuitive. Even the configuration and setup are pretty easy to do. It is pretty easy to use. I've done the restoration of servers several times, not as a disaster. When an upgrade on a server goes wrong and it messes things up, I can just fail back to a previous version and try it again. So, that has been really helpful."
"NetApp Cloud Volumes ONTAP needs to have customizable pricing options such as 10 TB increments. They seem to have only two options: 10 TB or 250 TB."
"We would like to have support for high availability in multi-regions."
"Something we would like to see is the ability to better manage the setup and tie it to our configuration management database. We manage our whole IT infrastructure out of that database."
"The data tiering needs improvement. E.g., moving hard data to faster disks."
"I would like NetApp to come up with an easier setup for the solution."
"I rate the scalability a five out of ten."
"The integration wizard requires a bit of streamlining. There are small things that misconfigure or repeat the deployment that will create errors, specifically in Azure."
"How it handles erasure coding. I feel it the improvement should be there. Basically, it should be seamless. You don't want to have an underlying hardware issue or something, then suddenly there's no reads or writes. Luckily, it's at a replication site, so our main production site is still working and writing to it. But, the replication site has stopped right now while we try to bring that node back. Since we implemented in bare-metal, not in appliance, we had to go back to the original vendor. They didn't send it in time, and we had a hardware memory issue. Then, we had a hard disk issue, which brought the node down physically."
"Zerto should add the capability to replicate the same VM to multiple sites."
"The only thing I really don't like about Zerto is that the ZVM has to be a Windows server. I can spin up any OBA template whenever I want to, but if it has an OS that's tied to it, then I have to involve the OS team from my company. That drives me crazy."
"There are certain things about the user interface that could be a little bit more user-friendly."
"Their data backup and restore have some ways to go."
"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."
"Some of the features need improvement. One would be, as you're creating a Move group or a VPG, as they call it, it should either autosave or have the ability so that you can save it for coming back to later because if the setup times out, you lose all your work. That would be a nice improvement to have."
"With secure boot enabled, which is the case for newer systems, it is not easy to rotate passwords and we would have to reinstall the DRAs."
"The alerting doesn't quite give you the information about what exactly is going on when an issue comes up. We do get alerts inside of our vCenter, but it doesn't quite give you accurate information inside the plugin to be able to tell us what's going on without having to go into the actual Zerto application and figuring out what's causing the issue."
