Senior Software Engineer at a outsourcing company with 10,001+ employees
Ransomware recovery has become validated and protects critical workloads across multiple accounts
The account onboarding process deploys around 20 IAM roles per account, which is heavy. Consolidating those or offering a slimmer permission set for read-only backup (versus full restore) would help with security review friction. Cross-account restore into a target account still requires manual steps for KMS. If Clumio could handle re-encrypting with the target account's CMK during restore rather than requiring Multi-Region Key pre-staging, that would save significant preparation time. Also, the restore API could surface better progress telemetry since right now, large RDS restores are a bit of a black box until they complete or fail. Finally, DocumentDB and MongoDB Atlas backup support would round out our stack nicely.

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

"Clumio gave us a genuinely isolated vault that sits outside our AWS Organization's blast radius."
"Clumio has a straightforward setup"
"Working with the Clumio/Commvault team has been a very good experience."
"We have been able to safely and securely save our backups off of AWS."
"It has improved our disaster recovery footprint; previously, backups were only stored on premises, and having an offsite backup improves our reliability and security."
"We now have the peace of mind knowing that our entire AWS infrastructure is fully backed up into an air-gapped environment."
"Clumio proved to be the most cost-effective option."
"I am impressed with the tool's technical alliance with Veeam and Veritas."
"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."
 

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."
"It would be beneficial to show when backups are available and to receive alerts if there are any issues with the backups."
"They need to improve their SQL backup services"
"More alignment with Clumio and Commvault branding would have helped us understand the product better during the discovery phase."
"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."
"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."
