Dive Into Mark today talks about doing backups with rsync and ssh. This is one of the things I really love about unix and one of the reasons I'm so happy that it is at the heart of OS X. Not to bash on MS, but how easy is to do the same thing on Windows? Without having to go out and buy more software. I think you might be able to do some of it with cygwin, but I'm not sure how easy it would be to get working. Note, it isn't necessarily the easiest thing to get working in unix, but it is very easy to find help online on how to do it.
