I don't keep separate files, but I do keep a "scratch" section at the bottom of my story. Any time I make a change that I think I might want to change back (i.e., not something like fixing a typo or a grammar error), I put the original version there. Sometimes it's just a sentence fragment, but sometimes I'll stick whole paragraphs in. That way, I can always go back if I need to -- like you, I find that immensely helpful.
