Look at the rsync package.  It is what is used for the Debian mirror
sites. From the man page:

DESCRIPTION
       rsync  is a program that behaves in much the same way that
       rcp does, but has many more options  and  uses  the  rsync
       remote-update  protocol  to greatly speedup file transfers
       when the destination file already exists.

       The rsync remote-update protocol allows rsync to  transfer
       just  the differences between two sets of files across the
       network link, using an efficient checksum-search algorithm
       described  in  the  technical report that accompanies this
       package.
