A backup file is stored in a directory that is accessible to actors outside of the intended control sphere.
Often, old files are renamed with an extension such as .~bk to distinguish them from production files. The source code for old files that have been renamed in this manner and left in the webroot can often be retrieved. This renaming may have been performed automatically by the web server, or manually by the administrator.
