A "reasonable strategy just for the operating system?"
Anywhere from a 32-120gb drive - or partition, to hold the OS and programs you use.
All else goes on one or more other drives which have their own backup scheme.
Personally, that's about 18gb for me, with 12gb images. I only keep a few images.
I only install Window once, and find the original worthless, because of Windows updates.
