If the intent is to re-use the same set of tapes, you'd could either set
the retention period to something less than 3 weeks (e.g. 19 days) or
manually expire the images on the tapes prior starting the next backup.
The later could be done using a combination of the 'bpexpdate' and
'vmquery' utilities.
Something like,
bpexpdate -m $media_id -d 0 -force
vmquery -deassignbyid $media_id 2 0
This could probably be scripted with a bpstart_notify.<policy_name> script
if you knew which tapes you would be using.
