Thanks Tyler,
However, for snapshotting to work, don't you have to have at least as much space for the snapshot as you do for the original partition? I currently am using nearly 60% of the VG just for backups, which is the root of the problem. It wasn't apparent in my scanning of the article (I'll go back and read for content in a bit).

As promised, how to use LVM to clone a BackupPC pool.
