I am in need of a good solution for backing up 4 computers wirelessly. 3 of them are Mac laptops and one is a Windows 7 desktop. Our wireless router is also getting old, slow, and unstable. I know that the time capsule will work with windows as a wireless router, but will I also able to backup the windows machine to it? Can I just partition it so one partition will work with the mac computers and the other will work with windows? If not, are there other solutions that are time machine capable AND windows compatible?
