Offers flexibility, fast performance, and ransomware protection
The platform is releasing new features at a fast pace, which sometimes leads to version updates every three to six months. Although updates are generally not complex, it is challenging to stop the production environment during these updates, even if the downtime is just a few minutes. This is a common challenge across all NAS providers. From my perspective, the most important area for improvement is developing a method to perform updates without affecting customer production environments. Additionally, there are some cache size limitations that might become problematic for future use cases, though they don’t impact current applications. Collaboration for NFS and SMB protocols could also be enhanced. Although this issue isn't specific to CTERA, it is something we are working on together to improve. The quality of the versions has improved, but occasional issues still arise. All solutions face this challenge, but we hope to see a continued reduction in the number of bugs. That said, we haven't had any major production problems in the last four years, and we appreciate how responsive CTERA is to our issues. We engage in brainstorming sessions together, and we value this relationship.

Enterprise storage system that offers consistent stability and data security
The replication capability and data security have been the most valuable features When retrieving data from the replication of remote sites, it does not give you immediate results. The RPO and RTO rates could be improved.  We have been using this solution for three and a half years. This is a…

Quotes from Members

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

Pros

"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."
"The support is awesome. It is top-notch. I would rate their support a ten out of ten."
"CTERA has out-of-the-box data protection capabilities."
"I like that the glass is always half full with CTERA file services. It keeps the data hot for users on location and then tiers off older data. If you need it, the stub is still there. You can click on it, and it's back on the device."
"The CTERA Enterprise File Services Platform is a hybrid solution that supports both on-premises and cloud environments."
"The best feature is the migration tool within CTERA."
"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."
"It is a three-in-one solution for us. It is a file-sharing platform, an archiving solution, and also a backup solution."
"It is not necessarily for the fastest storage or cluster storage, but just for pure storage, it's really hard to beat. It's just been around as long as anything else."
"Oracle ZFS is very fast and it is efficient. It has outperformed any hardware array controller that I've ever come across. With Oracle ZFS on my NAS, which is running five, four terabyte drives, when I've had a drive failure and changed one out, it'll rebuild that array in two hours, or maybe less. When you think you're rebuilding almost four terabytes of data redundancy, that's pretty good using an old AMD Turion hardware, that's nothing to complain about."
"The replication capability and data security have been the most valuable features."
 

Cons

"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."
"It has a learning curve."
"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."
"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."
"However, in some cases, they could improve performance."
"More monitoring from the platform would be good. There is some monitoring, but it is paid. It is a chargeable service. It would be good for that to be included in the base."
"I am looking for a process where version upgrades do not impact the customers. There is no downtime."
"One area for improvement is the migration tool, which at times does not work as designed, necessitating the use of alternative solutions like Robocopy."
"When retrieving data from the replication of remote sites, it does not give you immediate results. The RPO and RTO rates could be improved."
"Oracle ZFS does what I've asked it to do, and it has done it very efficiently. The only time I'm running into issues is with Proxmox. If I run ZFS drives, I find my RAM usage is very high. However, I don't have that problem with the TrueNAS system, where I'm running an old N36 Turion with four gigabytes of RAM, and that's running 24/7. There have been no issues with such a low-powered environment there, it works fine, but with Proxmox it seems to go slow."
"ZFS is great for just mass storage, but if you're trying to make fast storage – something like a SAN-type delivery network where you wanted to do any type of RAM disc over the network – it falls flat. ZFS does not do that. It is kind of limiting."
 

Pricing and Cost Advice

"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 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 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."
"So far, pricing seems to be fine."
"I am not directly involved in the pricing aspects, but I understand that CTERA's pricing is competitive and within industry standards."
"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."
"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."
