Keepit simply works - it does run on the servers of Keepit, I don't need to allocate disk space for it, and they also keep in mind that I need to stay GDPR compliant, so they host the data inside Europe when I am a European customer. It does cover what we need and the restore process is simple. Also, the data is stored in a format that I can download and work with. So, even when the target system (e.g. Dynamics or Exchange Online) is unavailable, I can still download the data and "work" with it - some data is stored as JSON, so I can write custom code to work with it. Integration with Dynamics, Exchange Online, Teams, SharePoint, and OneDrive for Business was very easy. The information mails about anomalities like deletion of large amounts of data are great! The subscription model did change, but the new contract partner did keep the rates, so: great!

We found very useful for NIS2 the audit log

Ease of onboarding with connector setup and easy restores with file through the UI
