Cloud data management that achieves cost efficiency with advanced data protection features
I am currently using Nasuni for seismic data. We have a huge data size, and we want to reduce costs. Nasuni acts as a caching solution, so we put some data into the cache, and the rest goes to the blob, which helps us save on costs. We use it for applications like Petrol and Tech Log, where 3D…

Provides fast access to files and offers a reliable backup solution without compatibility issues
Versioning control helps speed up data recovery by providing easy access to previous versions of files. This is particularly useful when moving backups to off-site storage and deploying them quickly during installations. My experience with Synology Backup's security features includes partitioning for production environments, regular scans for new threats, and support for multifactor authentication. Password security is also emphasized, meeting basic security requirements. Before choosing Synology, consider its sensitivity in your network infrastructure, especially for critical backup and storage tasks. Prioritize security, including testing and recovery procedures, and evaluate the device's performance to ensure it meets your needs effectively. Overall, I would rate Synology C2 Backup as an eight out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"The nice thing about Nasuni storage is that it is immutable. This means the data is only written once. So, you never modify the files. When you write a file out to the storage, it doesn't modify it when you change it. The technology knows how to figure out what the difference is between the original file write and what the changes are. Therefore, it only saves the changes."
"The solution gives us a breakdown and summary of every resource and each volume within every resource. It tells us the code within a given volume, so I can go in there and look at the size of the files that are stored there. Nasuni gives me the big picture and allows me to connect things like Power BI to any endpoint. I can take that tabular information from Nasuni and look at it in a graph."
"The feature I have found to be most valuable is the revision control of the files. If somebody deletes or accidentally makes a wrong change to files, we can go back to the revision history and restore the previous versions. That is a very good feature that we rely on."
"We like Nasuni's snapshot technology. The snapshot and recovery features are the things we use most frequently. Ideally, I would recommend NFS or CFS, which gives you more benefits for clients or anyone who wants to access FTP protocol, FTP utilities, SAN, and MSS."
"We've used it to provide file source capacity for VDI environments. The security of it is important and the fact that it's object storage, it's immutable and that it can't be held for ransom. It's a lot smoother than our previous processes that weren't Nasuni-based. A lot of it is done automatically just by the system being in place."
"Nasuni gives us a single platform with a 360-degree view of our data, which is important so that we know the size of our estate and the amount of data that we hold."
"The features I find most valuable in Nasuni are the unlimited snapshots, antivirus capabilities, auditing, and ransomware protection."
"It's good for file services."
"I find Synology C2 Backup valuable for its speed, features, and server compatibility."
 

Cons

"The only thing that I'd like to see is more support for platforms like OneDrive or Box.com."
"We can recover if data and a Filer are lost because of a possible ransomware event, but even that takes time to recover."
"When we have to rebuild a filer or put a new one at a site, one of the things that I would like to be able to do is just repoint the data from Azure to it. As it is now, you need to copy it using a method like Robocopy."
"Nasuni does not support different retention policies within the same volume, so you have to keep creating volumes for retention policies. When you create a new volume, it means you're starting from zero all over again. You can't move data between two volumes. You have to move them from your physical device to Nasuni or your cloud device to Nasuni."
"Some of their cross-platform features are really good, but it could always use more."
"Room for improvement would be the speed of replication of new files. I would also like to see cloud mirroring."
"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."
"We would like to have a user desktop agent to help improve the end-user experience."
"Improving the pricing would be great."
"The main drawbacks of Synology C2 Backup are slower processes in certain regions and less frequent updates."
 

Pricing and Cost Advice

"It is around $850 per terabyte per year. Any additional costs that you would incur are for the local caching devices that you'll need to access Nasuni. You kind of provide your own virtual machines or compute to access the data. You also pay for the object storage. So, there are three parts to it. There is the Nasuni license per terabyte. You would also pay for the actual object storage in the cloud, and then you would pay for virtual machines to access the storage."
"With this solution, the license renewal is pretty swift. With the virtual appliance, you just need to take care of the OS versions and patches. In a way, we don't have to struggle much with renewals because the only thing that we need to take care of are the licenses. We renew it every three years. This aspect goes with infrastructural costs because it doesn't cost us too much to maintain the solution."
"The cost is based on the capacity, which is approximately $100 USD per terabyte."
"There are cheaper forms of storage, but Nasuni is fairly priced for the functionality it offers. I can get basic file shares provisioned in Azure and pay for the storage and the CPU. The overall cost would be much less than Nasuni, but I would need to build the management console and encryption process, so it would cost a lot to develop that kind of functionality."
"I would not say it is economically priced, but it is affordable. If you can afford to pay for it, it is worth the money, but it is definitely not overpriced. It is priced about where it needs to be in the market. We were satisfied with the way they did their licensing and how they handled it. I believe they actually license by data size. It is based on how much data is being held on the machine and replicated, and that's completely understandable. So, for us, their pricing was as expected and affordable."
"Its pricing can get a tad expensive. When we first took Nasuni out, we were just paying for the service. We got storage at a reduced rate. It has now changed, and they're now more of an all-in-one type of thing. It can be quite expensive, but it works out. Apart from that, licensing-wise, it's very simple."
"The pricing is on par with everybody else, and fair."
"Its price is fair and reasonable. I don't have anything negative about its pricing and licensing. For us, there is also the cost of monitoring. We are monitoring through Xenos and not through Nasuni. That is another cost for us from the monitoring perspective, but as far as Nasuni goes, we don't have any other cost apart from the licensing fee."
