Plugin Name: WordPress Database Backup

Plugin URI: http://www.skippy.net/blog/plugins/

Description: On-demand backup of your WordPress database.

Author: Scott Merrill

Version: 1.8

Much of this was modified from Mark Ghosh's One Click Backup, which
|

in turn was derived from phpMyAdmin.
|

|

Many thanks to Owen (http://asymptomatic.net/wp/) for his patch
