title: How do I control how Emacs makes backup files?
body: <p>Emacs puts backup files named <code>foo~</code> everywhere and I don't like having to remember to delete them.  Also, if I edit a file that has a hard link somewhere else in the file system, the hard link points to the backup when I'm done editing, and that's confusing and awful.  How can I either eliminate these backup files, or have them go somewhere other than the same directory?</p>
