How to backup save files.

I want to go back and so some achievements that require a new save but I already have all 3 saves occupied and finished. Where can I find the save files on my computer and save them somewhere else?

I am only missing 2 achivements, "gold plated" and "IOU one, little buddy". I thought the first one was for buying everything but i didn't get it when i did so. The second one probobly has something to do with Burgerpant cuz he calls chara "little buddy"

Am I the only one who thinks Admiral Alphys resembles a Reptilian Female Colonel Klink from Hogan's Heroes?!
