We have a customer using Backup Exec SBS Suite v10.0 Rev 5520 (BE Service Pack 3). There daily backup is to a DAT72 drive & they've just hit the limit of a single tape (compression is on so actual size is subjective). The backup job is set to terminate in 12 hours of start up, which is 17:00. This way they should have their notification e-mails the next morning regardless of the state of the backup.
Since hitting the limit of one tape, the backup job (which fills the first tape well within the 12 hour limit) will sit there all night waiting for the second tape (quite correctly). The problem that is occurring is that the job is not getting terminated by the 12 hour limit. The backup job waits until the next day's tape is in the drive (typically around mid day) and completes the actual backup process. The job doesn't get terminated until the verification stage begins & only then does the job seem to realise it is way over the 12 hour limit & kills itself.
Is this normal behaviour and how can it be fixed (including if it is not normal)?
