The 20 days for restoring a deleted user hasn't changed in a very long time.
I can't even remember a time when it wasn't 20 days.
Restoring deleted user Drive data was also always 25 days, never 30.
With Vault, the amount of time one can recover user-deleted data can be extended to infinity, as long as the user account still exists. When a user account is permanently deleted (after 20 days), then Vault purges their data irrevocably. However, this purge process runs with a delay of 30 days, unless you've set specific retention rules to purge faster.
Also, Vault is not a backup service and can not under any circumstances restore any data at any time!
What Vault can do is export the retained data in MS Office compatible formatted files or PDFs.
I'm not sure any of this helps anyone in this thread, apart from serve as yet another warning to not delete users with content that should have been stored in a shared drive. 🙂
