I too have the same problem.
I wish I didn't have but one choice to turn off the backups and auto saves but a way to provide a folder for them to be saved in that I could find every time I needed to go back and restore a file that had been lost or corrupted. The whole idea of having autosave files and backup files that are directed to any folder by default and not to a folder that I can specify then just adds to the torment if a file is lost. Then you are searching your computer to find the files you need to restore the project. I save things regularly but when I'm in the heat of design I like having that autosave every ten minutes or so. But if it is going to save 13 or 14 files to my desktop every time I make a project I can't have it. my desktop would be filled with SKB files with no room for anything else. Is there another fix for this somewhere?
