Hi,

I don't know why you want this feature.
But I've written a well tested tool for backing up directories on
another disk which uses md5 sums to recognize same files (even in one
backup) and hard links them. By this way, it combines the advantages of
full and incremental backup. It also uses compression and has a lot of
other options and optimisations. It runs best with reiserfs, because
reiserfs has no preconfigured number of inodes and is fast with hard
linking.
So, if you need to backup, try
http://sourceforge.net/projects/storebackup
