rsync

This system administration enhancement is new in the Developer 2/07 release.

rsync is an open source utility that provides fast and incremental file transfer. This utility is used by system administrators to move, copy, synchronize data both local, and over the network. The rsync utility uses SSH as a secure transport between machines. rsync can also be used as a safe remote data backup tool for both full and incremental directory comparisons and transfers.
