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
