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. jon -- Jon H.
