Richard Saini - PeerSpot reviewer
The ransomware recoverability has helped with our data protection mandates
File replication and versioning seem to work very well. We did have some challenges at the beginning, but all of that has been resolved now. It works very well. It does what our users require. Replication is excellent. We needed that, and the versioning is also pretty important. One of the reasons we chose CTERA Enterprise File Services Platform was the requirements we had to have ransomware protection. Our existing solution at the time would not have met those requirements of being able to restore from a ransomware incident. What we wanted from a platform was the ability to restore a snapshot or restore a file system or data back to a previous point in time, and CTERA Enterprise File Services Platform offered us that. Availability was a very key feature of why we liked the solution. It is effectively like the disaster recovery feature, and that also lends itself to replication. It works very well for our ransomware recovery objectives. There is business growth due to being able to offer greater storage capacity for them. Before, we were running into storage limitations, and now that we have enabled CTERA, we can accommodate more data and users. When it comes to reduction in recovery time objectives, we have not used it in that way. However, we are anticipating that our recovery time objectives will come down from over a month to hours or days. Recovery point objectives will also effectively be down to hours. It is hard to say how much it has freed up IT resources for other projects or tasks. Now that it is fully implemented and fully working, we are spending a lot less time looking after it. It has drastically reduced the amount of time we used to spend on backups. It is hard to provide the metrics, but six hours a month or something like that would be fair. The ransomware recoverability feature has definitely helped with our data protection mandates. It has reassured our security teams that we are in a good place with regard to securing the data and being able to recover the data.

Has reduced downtime by enabling fast recovery after ransomware incidents
The facility to use Datto SIRIS is a function that I prefer. The user interface of Datto SIRIS is very simple and very user-friendly. The restore is very fast. The alerts that arrive in my email are very complete. Reporting in Datto SIRIS is very efficient. The reporting via email from Datto SIRIS for me, my customer, and my team shows that every single backup is okay or if there is a problem because the snapshot for the server is broken or another problem that I can address systematically. Since I started using Datto SIRIS, the time to recover data or servers has improved significantly; before, restoring a file or server was very long with the normal backup system. Datto reduced the time much more when I needed to recover a file or a machine. The cost for Datto SIRIS is very important. Using Datto SIRIS notably reduces time and introduces high-level security. Datto SIRIS positively impacts my organization by reducing downtime for the restore. The restore with Datto SIRIS is very fast compared to other solutions that I know.

Quotes from Members

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

Pros

"CTERA has out-of-the-box data protection capabilities."
"The features I find most valuable are in the gateways themselves. They have done a great job over the years of providing insight into what is happening with our products, with the batches that come through that are scanned. I enjoy that part of it, and it is fairly easy to use from our standpoint once we get to know the product."
"The CTERA Enterprise File Services Platform is a hybrid solution that supports both on-premises and cloud environments."
"CTERA has been particularly capable of keeping all of our workstations backed up. That became a critical feature for us during the pandemic when computers were rarely in the office. Everybody went off-site with their computers, and we were accustomed to working with a centralized storage infrastructure where people would come to the office and connect to the server to use, create, and modify files. Everything was done directly to that server."
"Our main reason for going for this solution was the uncontrollable growth of file data. It was unsustainable on our previous platform or technology. We needed something scalable like CTERA, so it was the scalability that we required."
"CTERA stood out due to its ease of use and superior security features."
"The support is awesome. It is top-notch. I would rate their support a ten out of ten."
"The solution provides substantial flexibility, allowing the separation of workloads across various hardware platforms without vendor lock-in. This flexibility makes it adaptable to future infrastructure changes."
"Since I started using Datto SIRIS, the time to recover data or servers has improved significantly; before, restoring a file or server was very long with the normal backup system, Datto reduced the time much more when I needed to recover a file or a machine."
 

Cons

"One of the bigger things that I would like to see is additional logging. There are logs in there. They provide us with the initial logs on what is happening on our CTERA device. I appreciate that, but they do not give us any further information. I would like to have more information on the logs themselves."
"The web portal that our users access to view data and backups could be optimized. CTERA could apply some of the improvements made to their administrative interface on the user side. The administrators are a much smaller group of people than the users, so it would be helpful if they targeted user experience resources to them."
"One suggested improvement for the CTERA Enterprise File Services Platform is the ability to distribute data across multiple active backend storage nodes rather than the current limitation of a single active node."
"Stability-wise, we just went through one issue that they addressed. We were having cloud sync issues."
"One area for improvement is the migration tool, which at times does not work as designed, necessitating the use of alternative solutions like Robocopy."
"The new Edge filer that they have comes with a lot more features than what we purchased. It would be better if we are able to add those extra features without having to swap out the hardware. A clear upgrade path for legacy customers would be beneficial."
"I am looking for a process where version upgrades do not impact the customers. There is no downtime."
"They fixed all the requirements that we had in the beginning. The beginning was a little bit rough, but we tuned it nicely. However, in some cases, they could improve performance."
"The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment."
 

Pricing and Cost Advice

"I am not directly involved in the pricing aspects, but I understand that CTERA's pricing is competitive and within industry standards."
"It is hard to compare the costs if we want to retain the same model of a separate high-performance storage or certain things, but it is one of the cheapest solutions available in Israel."
"CTERA's pricing model is competitive compared to other companies that achieve the same thing. Their closest rival is Nasuni, and CTERA is significantly more affordable than Nasuni."
"So far, pricing seems to be fine."
"CTERA's pricing seems to be on par with some of the other players, such as Nasuni and Azure. They all have benefits, but CTERA is competitive for its features."
"It is fairly priced. I am not too involved in the pricing of what we used to pay, but it would have reduced the cost of ownership. I cannot give a figure, but the EMC solution was very expensive compared to CTERA."
"I find the pricing reasonable. They offered us deals that helped us. Especially with the upgrade to a bigger unit last year, they were helpful with the deal."
