I’m no database person so I don’t know if this is possible, but a nice option would be to have urbackupsrv be able to wipe a corrupt database, and rebuild it based on the backups.
It would save losing all your backups when the database is corrupt beyond repair and you have to remove and reinstall the server software.
Also, it would be nice if the server S/W could make sure the database is healthy before it makes a backup.
Backing up a corrupt database defeats the purpose of the backup.
