<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>

If you've ever been saved by an Emacs backup file, you
probably want more of them, not less of them.  It is annoying
that they go in the same directory as the file you're editing,
but that is easy to change.  You can make all backup files go
into a directory by putting something like the following in your
```
.emacs
```
.
```
```
(setq backup-directory-alist `(("." . "~/.saves")))
```
```
There are a number of arcane details associated with how Emacs
might create your backup files.  Should it rename the original
and write out the edited buffer?  What if the original is linked?
In general, the safest but slowest bet is to always make backups
by copying.
```
```
(setq backup-by-copying t)
```
```
If that's too slow for some reason you might also have a look at
```
backup-by-copying-when-linked
```
.
Since your backups are all in their own place now, you might want
more of them, rather than less of them.  Have a look at the Emacs
documentation for these variables (with
```
C-h v
```
).
```
```
(setq delete-old-versions t
  kept-new-versions 6
  kept-old-versions 2
  version-control t)
```
```
Finally, if you absolutely must have no backup files:
```
```
(setq make-backup-files nil)
```
```
It makes me sick to think of it though.
