Accessible from anywhere without the requirement to purchase hardware

We are customers of Carbonite Backup and I'm the company IT manager The fact that we don't need to purchase any hardware is a huge benefit. It also means we can have access from anywhere. I think they could implement some new functionalities and I'd like to see some better training provided,…

It helped us save 40 to 45 percent on some types of data

It can provide a 360-degree view of your data, depending on how you implement it and whether you're storing your data in Nasuni. However, if you're working with multiple cloud providers, I don't think it's mature enough to provide a 360-degree view of what's in AWS, Azure, and Google Cloud. I think it can do it, but it's still a lot of scope and range fitting. Given that Nasuni storage is actually cheaper in some areas, it made sense for us to move a lot of our data away from Microsoft. Nasuni gave us more of a 360 view of that particular data type. Other data types are a little different because the company went in a direction where they wanted to store some stuff in an AWS S3 bucket rather than a file storage system. An S3 bucket has its advantages, but if you were to store more of your data in Nasuni, you would get a wider 360-degree view of it rather than on several cloud providers. I have data in AWS, Google, and Azure, and I would like to see a wider view of all the data stored across these three top providers. Currently, I use it for AWS and Azure, but I couldn't use both of them at the same time. I think Nasuni could have better visibility across these different areas. I had to take my data out and then do some analysis to get the costs. It would be helpful to have more built-in analytics tools to compare the storage costs between the various cloud providers. I would also like some graphing capabilities. We had a tool called Grafana that we used for graphing. I think some more visual analytics like that would be nice.

Quotes from Members

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

Pros

"We don't need to purchase any hardware for this solution."

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

"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."

"Nasuni offers us a single platform with a 360-degree view of our file data, which is definitely important to us. It simplifies IT operations tremendously. Because it is taking continuous snapshots, it eliminates a lot of work that was done previously when trying to manage backing up and restoring data files."

"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."

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

"The biggest and most impressive thing for us is the operational recovery (OR) and disaster recovery (DR) capabilities that Nasuni has. If a filer goes down, or an ESX server goes down, then we can quickly recover."

More Nasuni pros

Cons

"Lacks sufficient documentation or training videos."

"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."

"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."

"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."

"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 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 suggest Nasuni improve their syslog forwarders to support TCP protocol, as it's more secure than UDP, which is plain text and not protected at all."

"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."

Pricing and Cost Advice

Information not available

"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."

"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."

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

"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."

"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."

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

Reviews from Real Users

James J., IT Manager at a marketing services firm, says Nasuni’s management dashboard is helpful because he's able to view all of the different filers at once rather than check each one of them individually. He values the software’s security, reliability, good performance, helpful alerting, and responsive support.

According to a Server Engineering Services Lead at a mining and metals company, Nasuni offers good OR and DR capabilities, performs well, offers data security, and continuous file versioning helps recover from hardware failures.

The Managing Director of IT at a construction company appreciates Nasuni because it eliminates a lot of work that was previously done when managing backing up and restoring data files.
