Restore the backup to XAMPP localhost

I recently downloaded a backup for my web host, the extension is .tar.gz. I would like to restore the backup to XAMPP localhost so that I can operate on it locally. How do I extract those files (tried 7-zip, it extracted only 1 file with .tar extension)?

Extracting .tar.gz from with 7-zip is two step process.

  1. Extract .tar.gz, it will give you .tar file.
  2. Again extract .tar, it will give you backup files.

Make sure, you are using latest version of 7-zip.
