Think you are right, believe it still stays in the volume pool it was
assigned to :-)

Hi.
Failed backups do not occupy VAILD space on tapes. When a new backup runs
and appends to a tape which was used with a failed backup, Netbackup will
position the tape to the end of the last VALID image on the tape, thus
overwriting the invalid image.
If the tape was blank (in the scratch pool) , it will be placed in the
policie's volume pool, but after the backup has failed, the "Date Assigned"
value of the tape will be blank. I don't recall if the tape will return to
the scratchpool, but I don't think so.
Regards,
Jim

Anything other than an error code 0 or 1 is a failed backup; failed backups
do not create any valid images. The attempt, though, may still occupy tape
space until any other successful images on that tape are expired & the
entire tape is reusable.
There may be a delay in the time when a tape's images are expired and the
tape becomes reusable.
Look at the "bpexpdate -deassignempty" command to speed the process. It
also accepts a mediaid if you want to limit its effect. The command is
safe, not deleting any valid images. It's just a cleanup command.

Subject: [Veritas-bu] Images on media question
Running NetBackup 4.5 FP3.
A weekend Fullback loaded 4 different tapes according to the Activity
Monitor. The backup failed due to no available media. Running the Images
on Media Report for these tapes, I see no images for the failed backup.
1. I am not sure if the GUI is the best determinant of this.
2. Since the backup failed, does that mean the images that were backed up
are no longer on the media?
Thanks in advance.
