If you crank down dumpcycle in amanda.conf the program will do its best
to fit more on each tape. If you crank it down too far you'll get daily
complaints about it having to delay backups but it'll still do what it can.
That's what I've done to maximize tape usage in my setup:
single 50Gb AIT tape/day, 300Gb to back up. Tell it to manage full backups
of everything over 4 days of backups.
That's not really what I'm after. I'd like to have amanda to backup as
little as possible (i.e. high level backups, few level 0's -> long
dumpcycle), but I want it to stuff tapes until they are full. However,
currently when you run out of tape you are left with dumps in the
holding area that need to get flushed. I don't want to flush them, but
if you don't amanda believes that those backups have been completed and
figures it in to planning the next run.
