"...rsnapshot is a filesystem backup utility based on rsync. Using 
rsnapshot, it is possible to take snapshots of your filesystems at 
different points in time. Using hard links, rsnapshot creates the illusion 
of multiple full backups, while only taking up the space of one full 
backup plus differences."


As I said, double your disk space. The incrementals may be small, but the 
initial full backup requires as much disk space as the filesystem it's 
backup up.
