auto-backing up your .emacs

auto-backing up your .emacs

Can somebody help me please, I want to put this line into my .emacs -
'cp ~/.emacs ~/.emacs.d/.emacs-$(date +%Y%m%d-%R)' but it works as part
of a bash script, but I don’t know elisp to get it working in my .emacs.
What it does is save a dated and timed copy of your .emacs in your
~/.emacs.d so that when you're trying things out and learning how to
use .emacs you'll always have a backup copy. A case in point, last
night I had org2blog working, today, after fiddling its stopped
working, but if I'd had this operational I could just revert to a known
and working .emacs. So, can you help please?

Thanks
Sharon.

You should look into version control, like Git. It makes this process easy and integrates with Emacs with the Magit package.

You could look into the backup utilities that emacs provides out of the
box.  See the manual for further explanation: (info "(Emacs) Backup").

Hi Sharon

Emacs already have a builtin file version control.
If you use Emacs itself to edit your .emacs,
it will most likely create a .emacs~, which is a backup.
This is controlled by the variable make-backup-files.
Add this line to your .emacs:
  (setq make-backup-files t)

You may want to have several backup files.
They will be numbered with names like .emacs.~7~
Then add this line to your .emacs:
  (setq version-control t)

Of course this works for all files visited by Emacs, not only .emacs.

Look at the documentation:
  within Emacs, type C-h i
  then navigate to
    Emacs > Files > Saving > Backup 

Have fun

Thanks for this. I called up the package menu and found
'backup-each-save' so I've installed that to try out. Hopefully it will
work okay, but time will tell :)
