No, rsync will only hardlink to instances of the same file in the same
location from previous runs.  Backuppc will link every file with
identical contents even from different machines and locations.  And it
compresses them.  So you could probably keep 2 to 10x the history
online compared to anything else.   Plus it has a nice web interface.
