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.
