Hello

I'm still reading about Retention/Recycle but i think in your case the  
problem is that tape is the wrong tool for your backup. Tape backup is  
good for offsite copies or long term "archive" backup, but if you have  
only small amount of data which need very long to fill the tape you  
should consider using backup-to-disk on some cheap SATA and if you  
need aditional disaster protection do some offsite (tape) backup from  
your catalog and bacula disk archive.
With this you can use one tape for disaster backup, mark it as "used"  
after backup and let it expire in whatever retention you like.

Regards

Andreas
