About two weeks ago I asked about a way to use rsync to backup (I wanted to make something in-between a mirror and an incremental backup). I wrote a preliminary version of a program that does this (see http://www.stanford.edu/~bescoto/rdiff-backup), and am now considering adding remote filesystem support through ssh the way rsync does. Conceptually this may not be too hard, but there are probably issues that will arise that I don't foresee now. So if anyone knows of a description of how rsync does the ssh/rsh client/server bit, or maybe something more generic on how to use ssh in the way rsync does, I would appreciate a reference. I could look at the rsync source, but it doesn't seem to be overly commented, and I'm not exactly fluent in C and thought that this post might save me time in any event. Thanks. -- Ben Escoto
