Devin Mehta - PeerSpot reviewer
IT Manager Infrastructure & Security at VISBY MEDICAL, INC.
Secure backups have simplified compliance and now provide immutable protection for cloud workloads
The best features that Clumio offers are the ability to know when a backup has completed, to know how to restore both files at the file level and also restore EBS backups, point-in-time restores, as well as snapshots. Clumio has positively impacted our organization by providing us with the peace of mind of knowing that all of our EC2 instances are securely backed up. This peace of mind has translated into measurable outcomes as we adhere to NIST 800 compliance, and with that, we need immutable backups and the ability to have backups that do not exist within our existing tenants. Clumio fixes that problem for us.

Senior Manager at a manufacturing company with 10,001+ employees
Supports global file recovery and rapid data versioning across 80 nodes
When we implemented CTERA Enterprise File Services Platform early on, and we've been on the platform for three years, we have three different cloud portals. We have an EU portal, we have an Americas portal, and we have an APAC portal. It would be nice if we could combine that into one portal just for that global single pane of glass look. We've talked with them about that and they say it's challenging just because of some of the structure, but that would be something nice if we could get that. I integrated with Varonis, and because CTERA Enterprise File Services Platform didn't have initially a working relationship with that vendor, it would have been nice had that pre-existed us saying we need this. But that wasn't totally CTERA's fault. There was a lot of challenge working with the vendor to build out that interface. A single pane of glass for CTERA Enterprise File Services Platform would be beneficial. Everything else works fairly well. We've never had a point where we couldn't get to something that caused us to have a serious outage, and that to me is the mark of a good software package. It's never really caused us serious issues. We have our issues, that's true, and every software package does. However, we've always been able to meet the needs of the business, and we drive hard on security, stability, and scalability. From the scalability standpoint, that's one of the most important things to us. We're on their capacity-based licensing, so if I need to ramp up another CTERA Enterprise File Services Platform NAS, if we have an M&A, I can easily and quickly spin up another NAS and start doing that data transition fairly quickly. The biggest maintenance issue with CTERA Enterprise File Services Platform is firmware upgrades. We've done a lot of transition from hardware solution to virtualized infrastructure in order to minimize that hardware lifecycle portion of it. We have to upgrade the firmware and sometimes that can be challenging in the nature of business of our size with 80 CTERA Enterprise File Services Platform nodes around the globe. The issue we've had with CTERA Enterprise File Services Platform happened recently in a firmware upgrade where there was a major database back-end upgrade and that took some time. For our smaller sites, it would be an hour or two, and I can build that into a fairly easy change window. But in our larger sites where we may have hundreds of terabytes of data, that database update process took maybe a day or a day and a half. That becomes more challenging, especially in a manufacturing environment where people are wanting to access configuration files. We had to pin the data locally because the data would be available on the local edge filer, but the cloud sync, while it was updating the database, the cloud files weren't available. That would be the other thing I'd like to see an improvement on: some way to do those database upgrades either in a more segmented fashion or in some type of offline environment. I understand the logistics behind that sounds easy, but I'm sure it's not.

Quotes from Members

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

Pros

"We now have the peace of mind knowing that our entire AWS infrastructure is fully backed up into an air-gapped environment."
"We have been able to safely and securely save our backups off of AWS."
"Clumio has a straightforward setup"
"Clumio proved to be the most cost-effective option."
"Clumio gave us a genuinely isolated vault that sits outside our AWS Organization's blast radius."
"Working with the Clumio/Commvault team has been a very good experience."
"Clumio has positively impacted our organization by providing us with the peace of mind of knowing that all of our EC2 instances are securely backed up."
"The support is awesome. It is top-notch. I would rate their support a ten out of ten."
"CTERA Enterprise File Services Platform has positively impacted my organization in that it works as a file server, and centralizing things makes managing them in one location simpler than managing them everywhere else."
"The replication workflows have replicated content to our branch offices and cached that content, which makes that content accessible to our regional offices around the globe and makes accessing that data much easier and much faster."
"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."
"CTERA Enterprise File Services Platform has positively impacted our organization as it has allowed us to shrink our on-premise file system footprint, moving out from data centers and adopting a cloud-first strategy, which brings cost savings."
"CTERA's instantaneous and redundant file replication, available across multiple geographical locations, ensures easy and user-friendly recovery."
"CTERA is a very scalable product, allowing us to grow."
"CTERA has out-of-the-box data protection capabilities."
 

Cons

"The credit system can be confusing, but if you talk to your account manager, they can help alleviate those concerns."
"They need to improve their SQL backup services"
"We are still exploring the areas where improvements might be needed."
"More alignment with Clumio and Commvault branding would have helped us understand the product better during the discovery phase."
"The account onboarding process deploys around 20 IAM roles per account, which is heavy."
"It would be beneficial to show when backups are available and to receive alerts if there are any issues with the backups."
"I would rate CTERA Enterprise File Services Platform a nine out of ten because I think there are some shortcomings in the performance of the gateway that could be improved, and I realize part of that is we are running an older version."
"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."
"However, it is a bit difficult to find the files because I need to go through each and every folder step-by-step, and the search engine optimization is not that good, so I face some difficulties in finding the files."
"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."
"Stability-wise, we just went through one issue that they addressed. We were having cloud sync issues."
"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."
"However, in some cases, they could improve performance."
"In my experience, CTERA Enterprise File Services Platform is not stable."
 

Pricing and Cost Advice

Information not available
"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."
"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."
"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 am not directly involved in the pricing aspects, but I understand that CTERA's pricing is competitive and within industry standards."
"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."
