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.
