Well, I actually keep two backup copies.
1.- A "pre-Tuesday" one, which is really the "post-Tuesday" of last month.
This is the one I keep "outside" the computer in an external drive.
2.- A "post-Tuesday" one, of the current month.
This one is kept "inside" the computer in a dedicated partition.
So, after Patch Tuesday, I first push the "inside" copy "outside", deleting
the old one and then create an "inside" backup of the current state.
Better safe than sorry.
