Backuppc dedups (and compresses) at the file level using hardlinks. Not quite as effective as a block level if you have frequent small changes in large files, but still very good with no unusual filesystem requirements other than keeping the whole archive on one filesystem. It will link all identical content, whether from the same or different systems and it's rsync implementation can work with local compressed copies while chatting with a stock remote version. -- Les Mikesell lesmikesell at gmail.com
