I use in .emacs:
(defun my-desktop-save ()
(interactive)
;; `desktop-owner' is a new function in Emacs 22.1.50 to check
;; for conflicts between two running Emacs instances.
;; We don't want automatic saving in the second Emacs process.
(if (and (fboundp 'desktop-owner) (eq (desktop-owner) (emacs-pid)))
(desktop-save "~")))
;; Save the desktop every hour
(run-at-time 3600 3600 'my-desktop-save)
But maybe instead of requiring putting this code in .emacs for
every user who want to save the desktop periodically, we should
add a new user option to desktop.el that specifies time interval
of auto-saving? I think the default value of `auto-save-timeout'
is too frequent for a heavy function `desktop-save'. And also
standard auto-saving mechanism works on files, but the desktop
doesn't keep the desktop file permanently visited.
