Hello,

your solution IMHO only deals with backup file (*~), not with autosave files (#*#).
I have the following code in my .emacs, which does the trick for both kinds of files.

(defvar user-temporary-file-directory
   (concat temporary-file-directory user-login-name "/"))
(make-directory user-temporary-file-directory t)
(setq backup-by-copying t)
(setq backup-directory-alist
       `(("." . ,user-temporary-file-directory)
         (,tramp-file-name-regexp nil)))
(setq auto-save-list-file-prefix
       (concat user-temporary-file-directory ".auto-saves-"))
(setq auto-save-file-name-transforms
       `((".*" ,user-temporary-file-directory t)))
