Shared storage capabilities provide enterprise value with good reliability
Amazon FSx is more costly compared to other storage solutions like EBS or EFS. The auto-scaling feature should be improved, as it currently includes downtime. I need to manually increase the storage, which is not ideal. Integrating FSx with Windows Server is challenging; it's a long process involving Active Directory (AD) setup and synchronization.
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.

Quotes from Members

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

Pros

"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."
"FSx operates as an independent service, not tied to any server, which eliminates dependencies between applications for storage."
"On a scale of one to ten, I would rate Amazon FSx a ten."
"I rate the stability of Amazon FSx ten out of ten."
"The shared storage capability is highly valuable."
"CTERA stood out due to its ease of use and superior security features."
"CTERA has out-of-the-box data protection capabilities."
"The support is awesome. It is top-notch. I would rate their support a ten out of ten."
"CTERA is a very scalable product, allowing us to grow."
"The CTERA Enterprise File Services Platform is a hybrid solution that supports both on-premises and cloud environments."
"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 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."
"CTERA's instantaneous and redundant file replication, available across multiple geographical locations, ensures easy and user-friendly recovery."
 

Cons

"A direct FTP feature would be beneficial instead of relying on transmission services."
"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."
"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."
"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
"AI and automation features could enhance the platform, such as AI-powered search, predictive storage analytics, and intelligent alerts for proactive monitoring. Predictive storage analytics will help with better capacity planning. There can be some sort of intelligent alerts for proactive monitoring."
"I am looking for a process where version upgrades do not impact the customers. There is no downtime."
"Stability-wise, we just went through one issue that they addressed. We were having cloud sync issues."
"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."
"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."
"However, in some cases, they could improve performance."
"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."
"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."
 

Pricing and Cost Advice

"The lowest price I have paid is $370 or $380 per month, while the highest can exceed $3,000 per month."
"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."
"I am not directly involved in the pricing aspects, but I understand that CTERA's pricing is competitive and within industry standards."
"So far, pricing seems to be fine."
"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."
"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."
"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."
