Out-of-control backups!

[Sharon Kimble]

I need help with regard to my backups please. This is my relevant
section of my 'init.el'
--8<---------------cut here---------------start------------->8---
;; Save backup files in a dedicated directory
(setq backup-directory-alist '(("." . "~/.emacs.d/backup")))
--8<---------------cut here---------------end--------------->8---

Currently I have 38 backups of my 'custom.el', and 60 backups of my
'init.el', and a total of 9,941 files, which just shows the extent of
the problem!

How can I get it to just save 7 backups for each file and then delete
the rest please?

Thanks
Sharon.
