I don't think 'rsync' is available on Windows. You can go the other way, though, ie. backup Windows to Linux.
Having retweaked my setup I've started backing up everything in the house lately, and with my boxen either linux or bsd, rsync gets used. My wife just finalized her move from windows to mac (OS X), but the need existed to back up both machines. How I feared that I'd have to go without rsync! But that wasn't the case. Found gui rsync programs for both platforms, though I can't remember their names right now. I suspect 'winrsync' or 'windows rsync' were the search strings I used. The OS X software was right off Apple's site and was just a layer on top of a port of rsync methinks. -- The Toronto Linux Users Group.
