True. The original survived. But it must not always be so.

The point is losing the images in the holding disk and losing the
original data, which could have been avoided by NOT leaving them in the
holding disk,

Because planner needs it to decide how much to do before taper will
find it. It needs to be on the server in someplace like tapelist or

They already do. What does that have to do with not repositioning the
tape at all?

Taper basically does the same thing w.r.t. the "right" tape, so amcheck

Nothing. It's already there. Just leave the tape out of the drive and
make as many runs as you want into the holding disk. At your convenience,
run "amflush" and select "all" instead of a specific holding area
What would it take to have some sort of config option that did exactly
that? I have a 15/30DLT ... I have a 15gig holding disk ... when holding
disk is full, dump it all to tape and then backup to the holding disk
again ... then, your tapes would always be full and you don't have to
