I’ve recently moved large ammount of files between two backup sets.
The new backup set backs and uploads them, that part is fine. I however have this data still in the old backup, essentialy taking the double space in the remote location.
Is there a way to expire deleted files early and have them purged from remote (purge, download and repack archives, upload them, etc), so they no longer take any space in the first backup set?
--dry-run first helps safety, because an incorrect purge is irrecoverable.
You can’t ask to purge all files which are deleted. It would delete too much.
If you don’t care about old versions (and it sounds like you don’t for these),
deleting all versions with moved files will purge them but other files as well.
Exactly specifying what you want purged is safest, but method is up to you.
