As an addition to the previous tips.  In general making backup files is
a good thing, so you most probably don't want to turn it off.  But I
understand that you don't want to clutter the filesystem.  But emacs
allows to place the backup files in one single directory.  Here's the
config:

--8<---------------cut here---------------start------------->8---
(setq version-control t)
(setq kept-old-versions 0)
(setq kept-new-versions 20)
(setq delete-old-versions t)
(setq backup-directory-alist
      '((".*" . "~/.emacs.d/backup-files/")))
--8<---------------cut here---------------end--------------->8---

This saves the last 20 versions of all files I edit in
~/.emacs.d/backup-files/.  (Yes, I'm paranoid!  Additionally all my
important files are under version control (git, svn), too.)

Bye,
