rsync (1)            - a fast, versatile, remote (and local) file-copying tool

Rsync is the ultimate tool for copying files and is loved by many people. It offers many advantages over traditional methods like SCP or FTP which are linear file transfer tools. Rsync checks the delta of files between the source and the destination and only transfers the difference. Additionally it allows an option for easy compression of files before they are sent over the network.
