Having the storage of a NAS is fine, but you still need a program of some sort to get the data from machine A to machine B.

I'd even advocate running a small home server instead. I've done that myself. Take an old PC and toss in a few hard drives and then use that server as your data storage point. Microsoft makes and excellent product called Windows Home Server [microsoft.com] that will backup every machine on your network. There are also many free Linux options if you don't mind the learning curve.
