I have the following code in my ~/.emacs.d/init.el:


(defun delayed-recentf-save-list ()
  "Save recent files list when Emacs is idle."
  (run-with-idle-timer 10 nil 'repeat-recentf-save-list))

(defun repeat-recentf-save-list ()
  "Save recent files list when it was changed and Emacs is idle."
  (unless (equal recentf-saved-list recentf-list)
	(recentf-save-list)
	(setq recentf-saved-list recentf-list))
  (run-at-time 120 nil 'delayed-recentf-save-list))

(delayed-recentf-save-list)

It saves periodically (every 2 minutes), but only when the list has changed, and it waits until Emacs is idle for 10 seconds.
