Well, I did check, and there were no incrementals in the holding disk. According to the debug log, the planner fails the dumps right after building the schedule. >> In general, we only need one LTO1 a day, this particular DLE is a freak >> statistic well outside the standard deviations of the other DLE sizes, so >> doing a flush once every cycle is more appealing than allocating two tapes >> per run. > >Just because you set runtapes > 1 doesn't mean Amanda will use them all. >I keep runtapes set to a number higher than what normally gets used per >run, and have autoflush set true.

The higher >number just allows it to use additional tape(s) if needed. I was under the impression that Amanda would choose dump levels to fill as much of the tapes as possible. That's incorrect then?
