Open-source with great disk management and task synchronization

The system itself allows you to add any feature. The only bad thing is that this maybe depends on FreeBSD, and sometimes finding documentation is difficult. For example, we knew that previous versions automatically enabled the Linux kernel, yet with the recent version, this was no longer the case. Now, there was the possibility of being able to create Debian-based jails, and finding the documentation was not easy or fast. That said, in the end, we succeeded. If you find the documentation, it is always incomplete and fragmented.

Unified cloud file storage has simplified global data management and reduced operational overhead

From an admin perspective, Nasuni has various valuable features. The GUI is very good, upgrading is very easy, and DFS is very easily manageable. Compared with other products, the snapshot feature is beneficial because it creates a snapshot every five minutes, allowing me to provide restores very easily to customers. Data protection is enhanced by the fact that Nasuni uses S3 technology to create snapshots every five minutes and enables versioning, so the snapshot is created and I can utilize that snapshot for disaster recovery or restore purposes. I assess the value of global file locking and caching for reducing latency as good.

Quotes from Members

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

Pros

"The stability is quite good; our system is in production and we have not had any problems with it, and when a drive fails, we don't really have any disruption because we can easily rebuild the disk, even if it is very large."

"The fact that no data are lost when a hard drive fails is extremely reassuring, as I have had two of five drives fail at one time and no data were lost."

"Its stability is the most valuable. It is reliable, and we don't have to worry too much about it."

"The program is fast, fun to work on and easy."

"It has the best storage capacity."

"It integrates well into either Windows or Linux environments."

"The solution has been very stable so far."

"After using FreeNAS I will never spend money for commercial products like Dell or 3Par."

More FreeNAS pros

"The most valuable feature is disaster recovery. We can fully recover a site in two hours."

"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 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."

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

"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."

"Their backup strategy, as well as their speed of recovery, was amazing."

"Nasuni is helping us replace multiple data silos and toolsets with a single global file system."

"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."

More Nasuni pros

Cons

"Its support for Hyper-V clusters."

"If you find the documentation, it is always incomplete and fragmented."

"They should include clustering for the solution."

"The one thing that I find difficult to do which is very time-consuming is that I like to have a backup of the important files."

"FreeNAS should be better prepared for clustering."

"They can improve the integration with PSA systems. This functionality could be better."

"The support for S3 needs to be improved."

"Make it easier to find out how to fix things when something goes wrong."

More FreeNAS cons

"The customer portal could be improved, but it has been a while since I've used it. They might already have improved it."

"Nasuni provides enough reporting to see what's happening. You can see the number of shares, total volume, issues, conflicts, etc., but it doesn't provide much visibility from a content perspective. For example, it doesn't tell you the data age. When you're trying to sort and filter information, the data creation date is a critical factor. Nasuni doesn't give you that. You can't get a count of all the file types, like the number of PDFs, Word docs, and PPT files."

"I would improve Nasuni by addressing the performance issues we sometimes face on the base file share, which must be fixed, and granting some leverage to the admin to perform administrator-related tasks without needing to engage Nasuni support for every activity."

"If you need performance with less latency, you should go with another solution."

"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."

"It is difficult to configure Nasuni. Adding a filer is an easy task, but deciding where to add them, how many to add, and what size to add takes a lot of time. I have to analyze my existing storage to understand how many users are going to access which folders. I have to design the Nasuni architecture accordingly."

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

More Nasuni cons

Pricing and Cost Advice

"Its licensing cost is based on the hardware capacity."

"Its price is okay. It suits our needs."

"We use the free version of the program."

"For our configuration, we pay a little bit less than €10,000 ($12,000 USD) per year."

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

"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."

"The cost is based on the capacity, which is approximately $100 USD per terabyte."

"The pricing is on par with everybody else, and fair."

"Nasuni pricing is average; it's not too high or too low."

"It has a license fee as well as hardware costs, which we would incur if we want to use Nasuni Cloud Storage Gateway for upgrades."
