yea - that's what i do - save two or three times with separate names. Like, I'll save after each confirmed kill, then i'll save in a fresh one, then i'll save-and-exit (overwrite my exit save). If i load and the exit save fails, then the one before it usually is fine. Once in a blue moon I have two failures, and the third one prior is fine. I think once I had to go back before my last kill (three failed saves in a row) which was a piss-off, but it can mostly be avoided with super-redundancy.
