We'll create fresh WordPress site with Remote Database Backup installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin creates SQL dumps of your wordpress database. It is based on the WordPress Database Backup plugin(http://www.ilfilosofo.com/blog/wp-db-backup) – but it removes some of the security restrictions in the plugin to enable automated remote backups. You still need the admin user name and password to do a remote backup.
One the plugin is enabled, you create a backup by going to Manage > DB Backup. You can download the backups to your system or you can leave it on the server.
