I'm testing the backup/restore process, and I've schedule a full backup each Sunday at 1:00 AM, and an incremental from Monday to Friday at 1:00 AM.

When I tried to restore a corrupt mailbox from the administration console (and after with the CLI command "zmrestore -s myserver.mydomain.com -a myaccount@mydomain.com"), I had this error :
