backup file save not saving to backups directory.

[Sharon Kimble]

I am using this code in my 'init.el' -
--8<---------------cut here---------------start------------->8---
;;; from Tassilo Horn 11/08/14
(setq version-control t
      delete-old-versions t
      kept-new-versions 7
      kept-old-versions 0
      backup-directory-alist '(("." . "~/.emacs.d/backup/")))
--8<---------------cut here---------------end--------------->8---

When a file is saved, it is saved to its destination, but there is no
backup copy in "~/.emacs.d/backup/". How can I get a backup copy please?

Thanks
Sharon.
