We compared Nasuni and Zerto across several parameters based on our users' reviews. After reading the collected data, you can find our conclusion below:
Comparison Results: Nasuni is highly regarded for its storage capabilities, simplicity, scalability, and security features. However, it may require additional assistance during setup and could improve in terms of platform support and user-friendliness. Conversely, Zerto receives praise for its continuous data protection, quick recovery, ease of use, and integration with VMware. Its initial setup is straightforward, but some users express the need for enhancements in licensing structure and support. Nasuni prioritizes storage and IT operations, while Zerto specializes in data protection and disaster recovery.
"I can see who is logging in on files from all over the globe. For example, if a file is locked, maybe a user in Shanghai has locked files or something, I can see that from the Management Console, then unlock the file."
"Another helpful feature, in addition to restoring a file that was deleted within 24 to 48 hours, is that we have the ability to restore a file or a folder that was deleted, going all the way back to the inception of that file or folder. That means we actually have unlimited backups to the inception point of data with Nasuni."
"Its dependability and auditing capabilities are very important to us to be able to maintain a chain of custody of the information."
"I like the unlimited snapshotting."
"It has the ability to do end-user recovery, or a user can simply contact an admin who can perform a recovery from the management console. The versioning has simplified everything. Now we don't have to worry about those components."
"Continuous File Versioning is one of the best features because it helps you to restore at any point in time. That means you don't have to worry about a ransomware attack. Even if that attack happens, you can restore all the data to five minutes ago and save everything."
"Nasuni Management Console (NMC) is super valuable, and both physical and virtual filers are also valuable. NMC is the one-stop place for all our filers, both virtual and physical filers. They are definitely doing a great job in housing all our documents and surveillance videos."
"Snapshot backup is most valuable. It's quick and easy to use. It's controlled only by an administrator, which is very good. It takes 10 seconds to back up a spreadsheet of three or four megabytes."
"The testing features are the most valuable features of this solution. We use the failover test feature not just for testing failovers and disaster recovery, we've also had clients use it for development purposes as well as patching purposes to test patches. We can failover the VM and then we can make any changes we want without affecting production. It's a nice sandbox for that usage."
"We now have the ability to replicate critical data to a secure, off-site location that can be brought back in seconds if needed."
"I like the less than one-minute RPO, the ability to IP customize during failovers, and the cloning feature that I can use to clone VMs over at the target location. As part of the automation failover, if we need to change an IP when it fails over to the other data center, Zerto will handle that; there's no need for manual intervention. As far as the cloning, we use that to do quick testing of a VM in the remote data center for lift-and-shift processors."
"The most valuable features are the single pane of glass and the reduction in time it takes for our systems engineering team to manage the platform."
"Its ease of use is valuable. You do not have to do much to install Zerto or implement Zerto on the infrastructure. It is not very complicated."
"The recovery was pretty seamless. It took about a minute for it to kick over when we did our testing. So, it wasn't a long downtime."
"The orchestration and automation of the DR and how it replicates the VMs and then picks them up in the DR site have been most valuable."
"I found VM level replication and being able to group the VM levels to be valuable. I like not having to worry about whether a particular VM is in the right storage group; some of those sorts of things would trip us up previously."
"Nasuni recently implemented a health system for filers. However, it needs better visibility because it lacks data and an explanation, or reasoning as to why a particular filer may be unhealthy."
"The speed at which new files are created is something that could be improved. For example, if you create a new file in another country, I won't see it for between 10 and 15 minutes."
"The Nasuni file storage platform doesn't work well when there are a high number of small files. This is the case when a directory structure contains more than 10,000 or 20,000 small files, e.g., 5 KB, 10 KB, or 15 KB. When the user is accessing these files from another geographical location, they might face a slow response or timeouts when connecting to the shares, and then to the files. This is because the file size is small. There is a scope of improvement with this solution when it comes to accessing a large number of small files."
"The only issue we face with Nasuni is from the performance perspective. Sometimes, when we deploy a Nasuni device, it doesn't meet our requirements. It's a capacity-planning issue."
"One thing to consider is that Nasuni will have the same limitations that a traditional file storage solution will have, although that is because they are taking the place of a traditional architectural model. For example, Office 365 supports collaboration on documents such as Excel files and Word documents, but because Nasuni is a traditional file server, in that sense, it can't make use of that functionality."
"There is some room for improvement when it comes to monitoring. We are not using Nasuni monitoring. We are using our own monitoring through Xenos. Nasuni can provide better monitoring capabilities for us to monitor all the filers and NMC so that we don't have to use a third-party tool."
"The performance monitoring could be improved."
"The user-friendliness of its access needs improvement. When I log into the console, I see all the files that we handle globally. There are hundreds of Nasuni files that I can see on the console, but no way that I can filter them down. While this is a small thing, I need to scroll down and select the ones that I want. "Control F" doesn't work nor is there a dropdown menu that I can click on and select the ones that I want."
"Migration of complex VMware and Hyper-V solution. Using Zerto to replicate to azure and S3."
"It is crucial for Zerto to collaborate closely with VMware in order to promptly test updates."
"Zerto generates many false positive alerts, which is annoying. I still have thousands of alerts in my inbox, and those are false alerts. When I check there's actually no problem."
"Zerto could improve its reporting capabilities."
"Zerto's solution could benefit from additional security features, such as malware scanning tools at the recovery site."
"The number one thing we have found we would like changed so far is the cost per VM. It would be great to get that pricing reduced."
"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."
"It took me a little bit of time to get used to Zerto's terminology and to relate it back to how you do a backup traditionally. It was a little different. It took a little while to understand what a VPG is and what it does. That's an area that they could probably improve on a little, making the documentation easier to understand."
