I run into this myself on holidays. Originally I would reconfigure my
cron to just skip that day's backup, because no one would be here, the
data wouldn't have changed from my last good level 0. (We run level 0
every night). But then I realized I had this big huge holding disk
(duh). So I just let it run. The report whines that it couldn't find a
tape, so it left everything in the holding disk. The day after the
holiday I manually run the amflush to flush it to the tape it was
*expecting* the day before and then change the tape for the next night's
cron backup. There is no 'delay' in backup. It's one of my favorite
features in amanda, the holding disk.
