On top of Microsoft's resiliency measures, OnePlan takes nightly backups of all OnePlan data and store it in geo-replicated Azure storage for 30 days. We can use these backups to revert a entire OnePlan group back to a previous days backup.
Note
These nightly backups are only intended to be used in disaster scenarios, not for granular restores of a particular project.
After any data is deleted, or you cancel your subscription, all of the data will be removed in 30 days (after the daily backups are deleted).
