So, i have an X game that occupies like 20Gb, then, a patch comes out, but steam instead of just download and installing the patch, downloads the patch and it seems that copy the entire .exe file then patches it, and then copy it again.
I want to do this to be allowed to patch a game when i dont have enough free space to make the copy of the entire game.
It would be good to have an option to not backup on patch(maybe it's what steam is doing).

I've not seen this happen myself. (I've had several games installed, each larger than the total free space on the disk, and they were patched without issues. If this does happen for some game, it's likely specific to that game, or maybe to that specific patch. The patching process is a "black box" to the user, there's not really anything you can do to affect what it's doing.
