unwanted backup files with nnfolder archive method

unwanted backup files with nnfolder archive method

[Julien Cubizolles]

I'm using the nnfolder method to archive my sent mail and posts as
described in the Gnus manual with:

--8<---------------cut here---------------start------------->8---
(setq gnus-message-archive-method
      '(nnfolder "archive"
                 (nnfolder-inhibit-expiry t)
                 (nnfolder-active-file "~/email/Local/archive/active")
                 (nnfolder-directory "~/email/Local/archive/")
		 (nnfolder-get-new-mail nil)
		 (nnir-search-engine notmuch)
		 ))
(setq gnus-message-archive-group 
      '((if (message-news-p)
            (format-time-string "sent-news-%Y-%m") 
          (format-time-string "sent-mail-%Y-%m"))))
--8<---------------cut here---------------end--------------->8---

However, I've noticed that for each "sent-mail-%Y-%m" file, there is
also a "sent-mail-%Y-%m~" backup file created, with roughly the same
size: the size of the archive folder is then doubled. Is it the expected
behaviour, or is there some way to avoid these files ?

Julien.

Is this yours? :)

That's exactly what I needed, thanks. By the way, what command do you
use to cite an info node in this manner ?

Julien.

`boxquote-region'[1] and add a keystroke by hand.  Hehe.
Maybe automating it like `boxquote-describe-variable' will be
not so easy.
