dumpcycle: maximum number of days or weeks between full, aka level 0, backups.
You really want 3 weeks between full backups?
runspercycle: number of amdump runs in one dumpcycle
You seem to have this conceptually correct
tapecycle: number of tapes you want to cycle. Make it larger than one dumpcycle.
maybe even 2x, 3x, or 4x.
>From your "weekly backup" I suspect like so many before, you are trying to
fit amanda's nice round model into the square old-style scheme; full backups
one specific day a week, incrementals every other day.
If I'm correct and you choose to continue with your geometric squeeze,
I think you want a dumpcycle of 1 week and runspercycle of 1 for your
second configuration.
