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.

Incremental backup simplifies content recovery with beneficial features for email and file services
Almost all the features are valuable for Microsoft 365, specifically signatures and backup for email services and files for Microsoft. It is a full module suitable for any organization. The incremental backup feature is beneficial as it allows me to restore any imaging and filing with just a few clicks, simplifying content recovery after errors occur.

Quotes from Members

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

Pros

"Working with the Clumio/Commvault team has been a very good experience."
"Clumio gave us a genuinely isolated vault that sits outside our AWS Organization's blast radius."
"Clumio proved to be the most cost-effective option."
"Clumio has a straightforward setup"
"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."
"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."
"It has improved our disaster recovery footprint; previously, backups were only stored on premises, and having an offsite backup improves our reliability and security."
"The most valuable feature of CodeTwo Backup for Office 365 is its restore functionality."
"Almost all the features of CodeTwo are valuable for Microsoft 365."
"The tool's porting of targeted sources in CSV was a nice feature. The integration and connection between the tenants were smooth. We could access a template CSV as well."
"The solution offers ease of configuration. With a wizard, you run through the setup, and everything is configured correctly. Additionally, creating a job is very easy, and overall, the ease of access is excellent. Also, it allows you to use the backups to migrate to another Office 365 environment."
 

Cons

"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."
"We are still exploring the areas where improvements might be needed."
"They need to improve their SQL backup services"
"The account onboarding process deploys around 20 IAM roles per account, which is heavy."
"More alignment with Clumio and Commvault branding would have helped us understand the product better during the discovery phase."
"The customer service and support could be improved. When communicating via email, they sometimes take until late the same day to respond."
"There is room to improve in managing email signatures."
"I attempted to modify the XML files in the product's configuration to enhance the speed and efficiency of the process. While the KBs and documentation were well-written, technical aspects related to speed adjustment parameters were unclear."
"There are two major improvements. First, the UI seems outdated. Second, the tool should support cloud backups. I suggest using Windows Server 2016 or 2019."
 

Pricing and Cost Advice

Information not available
"The tool's pricing was reasonable. I don't remember the amount per mailbox, but the cost seemed fair, considering we had around 300 mailboxes to migrate and needed to do it in a rush over a weekend. We didn't have many choices for people to operate the migration."
