There's a few options:
- Add a "Volume Use Duration" to your pool configs. I use a value of "1 
days" for my daily backups so the tapes get marked "Used" after that 
time and will get recycled later.
- Set a "Maximum Volume Jobs" value in your pool configs. If the amount 
of jobs running to one tape is set and will not change often you can use 
this to get a tape marked "Used" as soon as the set amount of jobs are 
written to it.
