Borrowed from Sacha Chua https://github.com/sachac/.emacs.d/
This is one of the things people usually want to change right away. By default, Emacs saves backup files in the current directory. These are the files ending in ~ that are cluttering up your directory lists. The following code stashes them all in ~/.emacs.d/backups, where I can find them with C-x C-f (find-file) if I really need to.
(setq backup-directory-alist '(("." . "~/.emacs.d/backups")))Disk space is cheap. Save lots.
