Good point. Maybe yes. The point is that I would want the amanda log files the most, so I know where data is on my tapes. I could recreate the boot disks from source but I’d prefer not to do, in a hurry — so I’d best have boot disks there, too, so yes, let’s force those to level 0 too. > > IIRC, the taperalgo is in effect when multiple DLE's are available > for flushing.

I’m pretty sure my flush-threshold-* are already set to “always flush every last bit”; don’t save stuff on the holding disk, don't be frugal with tapes. And autoflush is set to “all”. Good point. Ok — let’s run another —no-taper dump of the one DLE that wasn’t already done at level 0.
