I confess I'm not the sharpest tool in the shed when it comes to backups. In trying to fashion backups of our SBS2003 Server to suit our taste--using only the native backup tools--we're running into a Catch-22:
The SBS Backup feature (aka Wizard) permits us to specify the number of backups to retain (we're backing up to external disk), but it only permits creation of one backup job. Meanwhile, the NTBackup program itself (aka Microsoft Backup) permits creation of multiple jobs but has no option to specify a number of backups to retain (only whether to append or overwrite). I notice that the specification for number-to-retain in SBS Backup is kept in the registry, whereas all parameters of jobs created in NTBackup are kept in the .bks files--and there's no script file switch to specify number-to-retain.
Does anyone know a way around this, ideally so that we can create backup jobs with NTBackup and specify a number of backups to retain (for each job), or failing that, whether any of the inexpensive third-party overlays to NTBackup provide this functionality?
