The idea is that you sync A to B with reference to C. If a file in A and C are the same, a hard link is created in B instead of a copy of the file. This means the only new files in B are files that have changed in A relative to C. When I start the backup I create a directory for the new backup, named with the date of the backup. If a symlink "latest" exists, I run rsync with the argument "--link-dest=.../latest". The new backup will be performed relative to the latest backup. When rsync is complete, I update the "latest" link to point to the just-performed backup. I periodically purge old backups, leaving behind backups ending in 01. This leaves one backup per month (e.g. 20090301, 20090201, etc) for a longer term historical backup. I have a script that does this for me which you are welcome to.
