They may be incomplete dumps. If there is a problem before a dump
completes you end up with a partial dump image in your holdingdisk
that never gets cleaned up. (To the developers: Since amflush seems
to know which ones are complete, can't it remove the incomplete ones?
Also, why does amflush mark a tape as used even when it doesn't write
any new data to it?)
> Anyone know how to just delete the held backup jobs?
'rm' works for me. Just make sure they aren't complete (try a verify of the
dump image) or are older than your rotation before removing them.
