I use (in addittion to the autosaves) three saves. I call it the rolling saves.
X1, X2, and X3 and alternate between those three progressively.
If X1 is at the top of the three and X2 is at the bottom Ill overwirte X2.
That way if one is corrupted I can roll back to the previous one.
(Please no X1 rants its just a random name.)
