rdiff-backup also does this superbly, see 
http://www.nongnu.org/rdiff-backup/. rsync and utilities based around it 
(such as rsnapshot) do it too, but rdiff-backup also offers efficient 
storage of multiple versions of the backup data, so that you can recover 
not only the most recent backup but also earlier ones, and without 
bloating the backup server.

rdiff-backup will work very well if you want to backup multiple copies 
of the same file or files over time from one source: it transmits and 
stores the data efficiently (with the latest version always being stored 
'in the clear' on the backup server). It has however no space 
optimisation strategy for backups from similar sources i.e. where you do 
backups from multiple computers and the sources have a lot of common 
data (system files etc). Storebackup might score over rdiff-backup in 
this regard? Backuppc (http://backuppc.sourceforge.net/info.html) can 
also do this (but I think without rdiff-backup's other advantages).
