Saving file before it is changed

Let's say I have a template that will reapply my, say,
/etc/ssh/sshd_conf if it has changed. How can I save the old one just
in case? Something like in /etc/ssh/Old would do fine; you get the
idea.

Something like the "backup" option in the template module?

      I have a feeling that might be exactly what I need. :wink:
      Thanks!

the backup feature should be really changed to do remote backups. This may come later.
