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.

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."
"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 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."
"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 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."
"The Nasuni management dashboard is helpful because, on the administration side, I'm able to view all of the different filers that we have in the UK, rather than check each one of them individually."
"With Nasuni, we have been able to replace multiple data silos and toolsets with a single global file system, which is important to us because we have been able to consolidate several different products and solutions."
"Nasuni has eased our job because we don't have to worry about the user requests for additional space anymore."
"I find Synology C2 Backup valuable for its speed, features, and server compatibility."
"It's good for file services."
 

Cons

"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."
"Part of the problem seems to be that Nasuni currently is not set up to do 24/7 support; they said that they were going to do that, so that was a little disappointing."
"The performance monitoring could be improved."
"There have been small shortcomings with support so it isn't perfect, although I don't think that any supplier I have dealt with has support that I would rate a ten out of ten."
"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."
"Room for improvement would be the speed of replication of new files. I would also like to see cloud mirroring."
"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."
"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."
"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

"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)."
"Our agreement is set up such that we pay annually per terabyte, and we buy a chunk of it at a time. Then if we run out of space, we go back to them and buy another chunk."
"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."
"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."
"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."
"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."
"Nasuni should provide small-scale licenses, like a 20 TB license. Currently, the smallest is a 30 TB license."
