RSYNC is small utility that was developed by two engineers (Andrew Tridgell and Paul Mackerras) and announced back in 1996. The tool is used to copy files between two systems over an SSH or stunnel.

This results in very efficient transfer of large files over a WAN link. For example, if you had a PST file that was 10 Gigabytes most backup programs would struggle to transfer this file daily because even if it changed by only a couple of Megabytes it would have to be re-transferred in its entirety each time.
