Basically you will be implementing Automatic recycling externally.

cron job each night to check the volumes.

1) grab the output of list media.

echo "list media pool=SomePool" | bconsole > output.txt

2) Filter this by the volumes that are Full or Used.

grep

3) Out of what is left do time arithmetic between the last written
date and the retention period (in seconds).

awk

4) If any volumes are recyclable. Select the one with the last written
the oldest.

5) Then purge that volume and relabel it to whatever you want.
