Use a NAS (network attached storage) disk. Attach the NAS to your router. Follow the instructions to set yourself up as a user (all NAS disks differ in their management).
Map your NAS share on your Windows machine. Use Cobian Backup 9 to backup your entire machine, or simply a location on a nightly basis. It's all free (except the disk), dead simple, and does what you need.
