Yep, detecting the os with nmap should work. Or if you are not using dhcp or 
only for one of them, you could distinguish by ip-address.

That will work until you install bonjour for windows (which is very nice in 
networks relying on zeroconf).

Using the same archive-method for both would involve either mingw with stuff on 
the windows-machine or exporting / as C$ in samba. But still you will have 
different paths inside these shares which results in files and paths only 
present every other day.
Better to use two different backup-"hosts" for the two os'es.

Have fun,
