Hi,
I want my emacs to backup every file on save (with version control),
but for some reason i only have one version of each file.
My configuration is this:
(setq make-backup-files t)
(setq version-control t) ; Enable backup versioning
(setq delete-old-versions t) ; Don't ask about delete old versions of
backup
(setq kept-new-versions 1000000) ; Remember 1M versions of backup
(setq kept-old-versions 1000000)
(setq backup-directory-alist (quote ((".*" . "~/.emacs_backups/"))))
How can have one new backup version created every time i save a file?

My setup is this:
(setq auto-save-interval 125)
(setq make-backup-files t ;backup my files
backup-by-copying t ;don't clobber symlinks
delete-old-versions t
kept-new-versions 6
kept-old-versions 2
version-control t ;use versioned backups
vc-make-backup-files t ;make backups for cvs projects
vc-follow-symlinks t)
;; Backups to central location
(setq backup-directory-alist `(("." ,@(concat user-emacs-directory
"Sicherungen"))))

I think backup-by-copying variable has to do with _hard_ links, not
symlinks.

Ah, yes! I first introduced 'backup-by-copying t' when I saw that my
clever hard links changed a bit. Years later I found that block (a
larger one, actually) and adopted it – with the original comments
included. And that one comment is presumingly wrong...
Thanks! I'll make an update to my init file.

If you read the description of `save-buffer', you'll see that this is by
design. I think this comes from the olden times when disk space was
precious.
How can have one new backup version created every time i save a file?

You can force a backup whenever you save, by mapping C-xC-s to something
like this:
(defun le::save-buffer-force-backup (arg)
"save buffer, always with a 2 \\[universal-argument]'s
see `save-buffer'
With ARG, don't force backup.
"
(interactive "P")
(if (and arg (listp arg))
(save-buffer)
(save-buffer 16)))

See the backup-by-copying-when-linked, -when-mismatch, and
-when-priveleged-mismatch variables for finer control over backups.

These variables (the last one actually backup-by-copying-when-
privileged-mismatch) play only then a role when backup-by-copying is
nil. The latter is non-nil. But it should be sufficient to let it be
nil and set backup-by-copying-when-linked to non-nil.
