Over the years I have come to love ssh and it's ability to make doing things across multiple machines so easy. Here is how I quickly backup all my personal files on my Mac directly over to my Linux server.
tar cf - /Users/scotbuff/ | gzip -c | ssh 192.168.0.102 "cat > macbackup.tar.gz"
You can easily script this to run on a regular basis and have a quick and easy backup. The great thing about this method is that you are easily backing up to another machine. You cannot get a cheaper backup alternative. I use an old machine running Linux, sure beats dropping any change on an external harddrive. Give it a try and feel free to include some interesting ways that you use ssh.
