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.

Expert Backup at a tech services company with 201-500 employees
A virtual deduplication backup appliance that protects physical and virtual data across remote sites, the datacenter and cloud deployments
Given its ease of use and management, I believe there are no specific caveats that users need to be aware of during the setup of DXRIS for backups. The process was straightforward, and I did not encounter any challenges or issues. As for a rating on a scale of one to ten, with one being the worst and ten being the best, I would rate the Quantum DXI Series a nine. My deduction is primarily influenced by personal preferences, particularly regarding the user interface and it is a highly commendable system, I would rate it a solid nine out of ten.

Quotes from Members

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

Pros

"We have been able to safely and securely save our backups off of AWS."
"Working with the Clumio/Commvault team has been a very good experience."
"We now have the peace of mind knowing that our entire AWS infrastructure is fully backed up into an air-gapped environment."
"Clumio gave us a genuinely isolated vault that sits outside our AWS Organization's blast radius."
"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."
"Clumio has a straightforward setup"
"Clumio proved to be the most cost-effective option."
"It has improved our disaster recovery footprint; previously, backups were only stored on premises, and having an offsite backup improves our reliability and security."
"While the challenges posed by the difficulties were significant, they prompted the replacement of problematic components, resulting in the resolution of issues. Importantly, there were no substantial ongoing concerns. Regarding the overall performance, it has been consistently excellent."
"I am impressed with the tool's technical alliance with Veeam and Veritas."
 

Cons

"The account onboarding process deploys around 20 IAM roles per account, which is heavy."
"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."
"They need to improve their SQL backup services"
"I was not a fan of the buy-up-front model due to the scaling of data size."
"The credit system can be confusing, but if you talk to your account manager, they can help alleviate those concerns."
"It would be beneficial to show when backups are available and to receive alerts if there are any issues with the backups."
"Perhaps the most notable area for enhancement lies in the web interface for management. The current limitations in LDAP editing capabilities are not addressed in the UI, and I haven't observed any recent updates. It's possible that the new version of the DXI service incorporates improvements in the GUI, but I cannot confirm. While there is room for improvement in the current GUI, it remains a relatively minor issue. Overall, the system is comprehensive, covering aspects such as reports on latency and networking, leaving little room for additional enhancements in those areas."
"The product needs to improve performance while scaling out. It also needs to improve stability."
