Rsync uses a quick and reliable algorithm to very quickly bring
remote and host files into sync. Rsync is fast because it just
sends the differences in the files over the network (instead of
sending the complete files). Rsync is often used as a very powerful
mirroring process or just as a more capable replacement for the
rcp command. A technical report which describes the rsync algorithm
is included in this package.

Install rsync if you need a powerful mirroring program.
