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).
