rsync is a clever algorithm for synchronizing files in a way that is bandwidth efficient.  It was invented by [Andrew Tridgell] and [Paul Mackeras]. It is described here:

http://rsync.samba.org/tech_report/

''rsync'' is also a program that implements the algorithm.

NasBackup [http://www.nasbackup.com/] is an Open Source Tcl/Tk application that provides a GUI layer on top of rsync.

[CMcC] notes that rsync can be used to backup a frequently changing database, for example by:

   rsync rsync://wiki.tcl.tk/wiki/wikit.tkd .

One would have to repeat the rsync until no changes were sent, though.  Is there some return value from rsync that tells you how much work it had to do?

[RLH] Are there any other Tcl/Tk guis for rsync?

Synopsis:

 Ran the installer
 cwRsync_2.0.10_Installer.zip

 Then found the example batch file, modified it by adding one line at the end:
 rsync rsync://wiki.tcl.tk/wiki/wikit.tkd .

 And then just ran the batch file
 wikit-rsync.cmd
 I renamed it with a .txt extension as well so it's not run by mistake.
