Recycling is the process of reclaiming space on archive volumes. The recycler works with the archiver to reclaim the space occupied by unused archive copies. As users modify files, the archive copies associated with the old versions can be purged from the system

-recycle_hwm 50 „high water mark “ – Percentage of the total storage space in the library that must be utilized before recycling will occur
-recycle_mingain 50 „minimum gain“ – Percentage of the VSN that must be expired archives before it can be recycled
-recycle_vsncount 1 – „VSN count“ – Maximum number of VSNs recycled in one recycler run
Creating a crontab File for the Recycler If the system is performing as expected, you are ready to make a crontab entry for the superuser to run the recycler periodically, every two hours or more, depending on your site’s conditions
# EDITOR=vi
# export EDITOR
# crontab -e
