rsync can do that, files get copied by a checksum compare, if they are 
different, than that 64k block is pulled from the src.  If no changes, 
no update.  New files get a full copy.  But you will need scratchpad 
space for the biggest file available to do this.  rsync is pretty 
bulletproof, I've been using it here to make backup dirs of important 
dirs on other machines on my own LAN for several years now.  I have it 
as a cron job & it sends me an email every morning showing what it did.
