Urk, insufficient coffee this morning.  In my previous reply I thought
this was the backuppc list.   Backuppc does in fact do a very good job
of storing backups in minimal space - and can use rsync to do it while
also maintaining versioning so it is great as a generic backup
solution.    But, it doesn't have anything built-in to delete target
files after the copy.   There is an option to run post-backup scripts
that might work.
