An official implementation of the rsync protocol for Windows. Has a handy wizard which walks you through picking the directories you want to back up, the host and directory you want to back up to, how you want to connect (hint: if you're backing up to a Linux box, Windows Backup Agent natively supports SSH!), and when you want the backup jobs to run. Windows Backup Agent will then run in the background of your Windows machine and periodically SSH into another machine to rsync files over to it to back them up. I use it on my Windows machines at home and I'm very pleased with it.
