rsync -- a fast, versatile, remote (and local) file-copying tool
Rsync is a fast and extraordinarily versatile file copying tool. It can copy
locally, to/from another host over any remote shell, or to/from a remote
rsync daemon. It offers a large number of options that control every aspect
of its behavior and permit very flexible specification of the set of files
to be copied. It is famous for its delta-transfer algorithm, which reduces
the amount of data sent over the network by sending only the differences
between the source files and the existing files in the destination. Rsync is
widely used for backups and mirroring and as an improved copy command for
everyday use.
