Normally all incremental (differential) backups according to the retention policies plus all full backups that they depend on. So one would normally expect to see at least one diff and one full. Now, your retention period is actually shorter that the interval between backups. I'd expect to see at least one full and optionally an incremental if the last backup made was not the full. > David -- Met vriendelijke groeten/Kind Regards, Remco Post [email protected] +31 6 248 21 622
