More likely, the editor will just ask you if you want to recover the
auto-saved version the next time you open the file.  (Or do what Emacs
does, which is open the file normally but display a message suggesting
you execute "M-x recover-this-file".)

If you choose to run such a script, I would recommend using one that
only deletes files that are several days old.

If you're concerned about that, customize kept-old-versions and/or
kept-new-versions to manage the number of backup versions that are
saved.
