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.
"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."
"We use Nasuni's continuous file versioning feature and it fully protects us. With the ability to version files and have continuous recovery, it helps in terms of resiliency. If we have an incident then we would be able to easily recover from it by using the technology."
"My clients are happy with Nasuni because the transmission is seamless, and it consolidates all the existing file servers into one location. Also, Nasuni has no boundaries. It's infinitely expandable. They don't have to rely on the service provider for backup and restoration. It's self-serve."
"Nasuni has helped to eliminate on-premises infrastructure. We were using about eight to 10 different types of vendors or small storage boxes for provisioning and shared access for users. We got rid of all those. That has eliminated operational overhead and footprint at our data center. We don't have to worry about any hardware or monitoring particular devices, and hundreds of devices have been decommissioned. Now, for provisioning, everything is on Nasuni. I assume this has made a big difference in costs."
"With Nasuni Management Console (NMC), we get a single, centralized view of our entire internal structure and data center structure. This is very important because this caters to remote locations. One of the main care center teams is dependent on this solution. As it is directly connected to customers for the calls that they receive and troubleshoot, they can then help customers out in case they are not able to place an order."
"Nasuni gives us a single platform with a 360-degree view of our file data, which is very important to us. We have everything that we need to look at in a single pane of glass."
"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."
"The snapshot functionality and the unified file system are definitely the most valuable features for us. The UFS allows everybody across the organization to see the exact same data at the same time, instead of having different file servers with different structures on them, and that's mission-critical. We have different branches throughout our organization that have to act on that data."
"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."
"Zerto helped our organization meet compliance requirements by ensuring data protection and recovery strategies align with our regulatory standards."
"The ease of use is one of the best features. Previously, we were using Site Replication Manager with VMware and it was a little bit cumbersome. With Zerto, we liked the fact that it was hardware-agnostic and we were able to spin it up pretty quickly and get it working."
"The biggest benefit is the application-consistent disaster recovery functionality."
"During a failover to a DR site, Zerto can automatically change the IP address of servers."
"We can failover to an isolated environment and validate the application without impacting the production environment. We can do more testing in a non-impactful way..."
"It is the backbone of our DR solution for critical databases that hold the data we can't afford to lose. It provided new opportunities to change how we approach disaster recovery."
"It enables protection of a virtual workload to be done by the app, whether single or multi-tiered, with a boot time scheduler. It is pretty awesome."
"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 performance monitoring could be improved."
"Its interface design or the graphic user interface design can be slightly tweaked in some areas. Some built-in setup wizards would be very beneficial. Rather than having to go in and configure it by hand, there should be more setup wizards for onboarding new data shares and getting it set up the way you want. I don't know if these are on their roadmap, but I sat down and talked to them about some of the work concerns, some of the things that we liked, and some of the things that we didn't like. They are probably working on that."
"We forecasted that the data at my client's organization would grow by about ten percent annually, but we are migrating more data because we are bringing in some servers that had not previously been within the scope of our license. We expected it would take us two years to reach a specific amount of data, but we hit that mark in one year. The licensing cost skyrocketed, so we need to renegotiate. It puts us in a bind because we are reliant on Nasuni for our service strategy. We can't deny our customers, but we also struggle to pay for that."
"The customer portal could be improved, but it has been a while since I've used it. They might already have improved it."
"I would like to see Nasuni create a Dropbox or Box alternative. One of the things that people like about those tools is that they are very easy to implement. They look just like a file server. With Nasuni, you have to be online to get your file storage. With Dropbox, there is a thing running on your PC that downloads the files to it when you need them, i.e., an agent."
"There are some issues with multiple users accessing the same file simultaneously. There would be times when the global file would lock when several people tried to access it, so that could be optimized more."
"I would like to see them improve their tools in regards to accessing data using smartphones, tablets, and iPads. I think the Nasuni app could be improved to make access to the data cleaner and more efficient."
"The onset of configuring an environment in the cloud is difficult and could be easier to do."
"I wish Zerto had better file restoration capabilities. We have not been able to use that because of the limitations of Zerto's de-duplication technology."
"Analytics has a 90-day window, where it keeps data. It would be nice to have on-prem storage instead of cloud storage for that so we can keep the data for longer. Unless you discover the problem within three months, you don't know that you need the data. Then, it is gone by the time you realize there is an issue."
"The solution is very expensive."
"The only issue that I observed was that depending on the number of virtual machines that are being replicated, you will have to provision the appropriate bandwidth for the link that the replicated systems will traverse."
"The product could benefit from improvements in automation, specifically in the area of failovers."
"An area for improvement is the support because it gets really expensive. They need to make it a little cheaper. Support also takes time."
"Another thing that would help would be a recommender, or some type of tool that says, 'Hey, you're not conforming to best practices.' It would do a conformance or compliance check to tell you if your VPGs are set up according to best practices and whether your Zerto clusters are set up optimally. It would see if you have HA enabled and whether your alerting is turned on."
