I'm sure there are several things to consider here but one thing that comes to
my mind is that your holding disk should be at least large enough to hold one
nights worth of backups and maybe a little more. That way in the event that
for some reason amanda can't dump everything to tape at least you have a copy
on disk that you can flush to tape after you resolve the problem with the tape
drive.
