With reference to http://dan.langille.org/2013/03/07/deleting-old-bacula-volumes/ this is a good start. I reckon it'll be useful. If you can avoid bash in shell scripts, it'll be more likely to be adopted by those without bash.

Hello

Good script, Now is it possible to select lastwritten from media only for specific client?

Actually I want to delete few days old data only for one client including any prune, purged and from /var/lib/bareos/storage
