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, giving it a five out of five.

Quotes from Members

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

Pros

"What I like about it is that I can work on it from any computer or any device. The initial setup is very simple. The setup wizard is really helpful."

"The solution has been very stable so far."

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

"FreeNAS is much simpler and easier to use than other solutions, but we don't have the complete range of features that come with the full version."

"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."

"It has the best storage capacity."

"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."

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

More FreeNAS pros

"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."

"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 global file locking feature is valuable. The ability to quickly deploy new sites is also valuable."

"The ability to access anywhere, the ease of deployment, and the security are the most valuable features."

"Nasuni has helped to replace multiple data silos with a single global file system, providing a single platform with a 360-degree view of our data so we can secure it properly, ensure resiliency, and maintain the visibility required for strict regulations like GDPR."

"My advice for anybody who is considering this product is that it works great."

"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."

"With Nasuni, the simplicity of management is light-years ahead of our previous processes because the old backup and recovery was so slow, and we had to keep growing the SAN as the business grew."

More Nasuni pros

Cons

"FreeNAS should be better prepared for clustering."

"The support for S3 needs to be improved."

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

"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."

"Its support for Hyper-V clusters."

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

"They should include clustering for the solution."

"One of my hard drives has failed and the documentation that I've been able to find has not helped."

More FreeNAS cons

"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."

"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."

"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."

"We would like to have a user desktop agent to help improve the end-user experience."

"Some applications may not be suited for the Nasuni environment. You may need something with better performance. Otherwise, if you want to run daily operations or some file system, it's a good bet."

"We've had some organizational changes that Nasuni has not been able to keep up with, mainly from a data or file system perspective. Moving a filer from one management console has been a challenge. It lacks the flexibility to move files in and out of the management console. We have six management consoles now, and we're constantly telling Nasuni, "Hey, please allow us to move a filer from management console A to B." They can't do that."

"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."

"The performance of the filesystem could be improved."

More Nasuni cons

Pricing and Cost Advice

"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."

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

"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."

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

"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."

"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."

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

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

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