I had to delete a Google apps user, and during the process deleted all the documents it owned.
I guess I can not restore that but is there a backup on Google servers anywhere?
Is there another way to restore these files?
Found it: When a user is deleted, it can still be restored, as well as all the documents it owned for 30 days.
Go to the manage panel, and on the Organizations & users select the list: Recently deleted users.
You can restore the user as long as it's shown here.
