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

"We have less downtime and fewer trouble tickets from users who cannot access their shared files. Nasuni has reduced the friction and noise associated with file management because the devices are more reliable."

"The most valuable feature is the storage in that it only keeps the last-used data locally, while everything else is backed up to the cloud. That way, we never really have to worry about file space in each office or the replication to the other file servers for DR."

"I would recommend Nasuni because it's a proven product that has delivered results for us even in the worst-case scenario. If you're still using a traditional cloud solution like native Azure products, you are still susceptible to human error. Also, you would need to architect your backup and DR solutions, then integrate, maintain, and administer them."

"Its dependability and auditing capabilities are very important to us to be able to maintain a chain of custody of the information."

"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."

"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."

"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."

"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."

More Nasuni pros

"I find Synology C2 Backup valuable for its speed, features, and server compatibility."

"It's good for file services."

Cons

"Nasuni could improve cloud integration and documentation of various ways we can leverage the product. It integrates with Azure, but the native Azure File Sync solution lets you divide data into tiers like hot, cool, and archived. Nasuni doesn't allow you to break the data apart into those tiered categories."

"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."

"Room for improvement would be the speed of replication of new files. I would also like to see cloud mirroring."

"I would like to see Nasuni provide the ability to mirror a Nasuni appliance from one site to another. They could maybe have a standby appliance that is mirrored in a different location for disaster recovery purposes. We can recover if data and a Filer are lost because of a possible ransomware event, but even that takes time to recover. If we had the ability to have a mirrored appliance, we could flip over to that mirrored device and resume instantly rather than repopulate the local appliance with data from the snapshot history in the cloud. This is another feature that we would really like to see, if possible."

"One area that we've recently spoken to Nasuni about is single sign-on. Another is integrating Nasuni with Azure Active Directory. In our particular case, that would allow for third-party consultants to access our Azure Active Directory environment as opposed to coming to our on-premises environment."

"The privilege settings need to be more granular, and alerts are an excellent example. If a user doesn't have access to them, they can't see them and access information such as what they may have done wrong, what's there, and when the last sync happened. However, the ability to view alerts also comes with permission to delete them, which is not good, so we need more customization options here."

"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."

"The only thing that I'd like to see is more support for platforms like OneDrive or Box.com."

More Nasuni cons

"The main drawbacks of Synology C2 Backup are slower processes in certain regions and less frequent updates."

"Improving the pricing would be great."

Pricing and Cost Advice

"The pricing is fair. It's an enterprise-level solution so it's not inexpensive... The cost is pretty stable year over year."

"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."

"They could lower the cost, but it saves so much money when you go into it (by losing all the backup)."

"It's cheaper than a lot of alternatives but it's not cheap."

"There are annual costs that we pay for maintaining all of the snapshot history in the cloud. That is the primary cost that we pay. We occasionally buy newer Nasuni appliances or deploy them to new offices when the need occurs. That capital equipment expenses is less than the cost of buying new file storage systems. For the most part, you are trading a CapEx cost of storage equipment for an OpEx cost for management of all the snapshot data in the cloud."

"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."

"The cost of licensing is negotiated and billed annually per terabyte."

"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."
