On a page within the “Tools” Submenu, you’ll find a simple form which lets you choose the ingredients of a current Backup:
<ul>
<li>Uploads (either by scanning your Upload Directory, or by fetching Attachments from your Database)</li>
<li>Active Theme (and its parent theme, if used)</li>
<li>SQL-Dump containing the Mysql Database</li>
<li>A list of active Plugins</li>
</ul>
Backups will be stored within a folder in wp-content and be downloadable from the Backend. Once the downloads are finished, the backup files on the Server can be flushed.
What’s good:
<ul>
<li>Simple: Choose what is included in your Backup and download the resulting ZIP Archive from your Backend</li>
<li>Unobtrusive: It’s nested within the “Tools” submenu and comes without any bling bling, following default WP Backend Styles</li>
<li>Lightweight: 28KB zipped, 72KB unzipped</li>
</ul>
The plugin author does not take any responsibility for the safety of your data or the integrity of the generated backups.

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.
<h3>How to Use</h3>
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.

Remote Database Backup

Lets you create and download SQL dumps of your wordpress database for backup.
