One way to do it would be to use the auto-save which
Emacs already uses.

;; These are my values (which are probably default) but
;; even if you already have them, and the mode enabled,
;; it might be interesting to see - use `C-x e' with

;; their values. (Otherwise just setup as you please.)

(auto-save-mode)              ; enable auto-save
(setq auto-save-interval 300) ; auto-save every 300 keydowns
(setq auto-save-timeout 30)   ; or after 30 seconds of idle

;; whenever so, save the messages buffer
(add-hook 'auto-save-hook
          (lambda ()
            (with-current-buffer "*Messages*"
              (write-file "~/emacs_messages" nil) ))) ; nil: no confirm
