After using the Backup app and selecting OneDrive as the backup destination (source: ZimaBoard - destination: OneDrive), my OneDrive and Dropbox mounts disappeared from the Files app. I also have Google Drives that are still there
They no longer appear under External / Cloud sources.
When I try to add the cloud account again, nothing happens, No error message, no confirmation, and the mount is not added back.
However, via SSH, I can still see leftover cloud-related directories under /media

OneDrive directories exist under /media but are not mounted (different from google drive):
Any ideas?
This looks like a UI / mount state desync rather than actual data loss.
What’s likely happening is that the Backup app temporarily takes ownership of the cloud mount, and when it exits, the Files app doesn’t re-register the mount correctly. That’s why the directories still exist under /media, but OneDrive/Dropbox no longer appear as active cloud sources, and re-adding them silently fails.
Google Drive still showing is the giveaway, it’s mounted via FUSE and remained attached, while OneDrive/Dropbox didn’t remount.
At this point:
- The cloud data itself is not gone
- The Files app has simply lost track of the mount state
- Leftover directories under
/media confirm this
A reboot usually restores visibility. If not, removing the stale cloud entries and re-adding the account after reboot typically fixes it.
This feels like a Backup + Cloud integration bug rather than user error, especially with no error message or confirmation shown in the UI. Definitely worth reporting so IceWhale can tighten the mount lifecycle handling between Backup and Files.
