WP Staging - DB & File Duplicator & Migration
https://wordpress.org/…/wp-staging/

This duplicator plugin allows you to create an staging or development environment in seconds.

It creates a file clone of your website into a subfolder of your current WordPress installation with an entire copy of your database. This sounds pretty simple and yes it is! All the hard time consumptive database and file copy stuff including url replacements is done in the background.
