Overwrite a Backup

In both the Pro and Lite versions, Overwrite mode is available. The Overwriting allows users to replace an existing WordPress site with the contents of the archive.daf file. The process for overwrite closely resembles the Classic Install process, with the main differences being:

  • Classic Install requires an empty directory with only the installer.php and archive.daf files.
  • Overwrite install will replace any existing files and the Database of the current WordPress site.
  • Overwrite install automatically detects the existing site’s database and pre-fills the database credentials.

Overwrite works with Lite and Pro versions of the Duplicator Plugin.

Create a Backup

To start the backup process, head over to Duplicator Lite/ Pro » Packages » Create New:

Package Files include installer.php & archive.daf from the source site.

Copy the Backup to the site directory.

Copy the package files to the site directory of the existing WordPress destination site using FTP, cPanel, etc.

You can refer to this guide to understand the WordPress File and Directory Structure.

Run the Installer.php file.

  1. Open the site directory of the destination site, copy the installer.php and daf file.
  2. Go to
  3. Verify and continue with the pre-filled database inputs from the existing wp-config.php settings.
  4. Proceed through these steps and login to your newly overwritten WordPress site.

For both Pro and Lite versions, existing content like plugins, themes, and images will still appear after installation if they were not initially in the archive file.

If a plugin, theme, or file exists in the current site but not in the archive file, it will persist.

After the installation, the plugin will be displayed as a disabled plugin. This behavior will not affect the site’s operation, as it is part of the expected process where only the archive files are extracted. For a guaranteed clean slate, it is recommended to use a Classic Install.
