This is the scenario; If a backup to disk job fails for any reason whatsoever, even if it's only missing one file or directory, it automatically causes a duplicate to tape job to get skipped and then it requires creating a manual duplicate to tape job for that backup set just to get your data backed up.
If you're backing up multi-terabytes worth of information and a backup fails for a single missing directory, I still want/need that data to be duplicated to tape regardless! The software needs to be smart enough to do this because I can't babysit backup jobs that sometimes take four or five days to complete by themselves, not including verification. Even if the job failed entirely, I would still want whatever data that actually was backed up to be duplicated to tape.
