I'm looking for a way to script the process of creating a snapshot of
a database as a backup in Windows XP.

I currently create snapshots by exporting the database with
phpMyAdmin. This involves running phpMyAdmin in the browser, entering
the password, clicking Export, setting a couple of fields in the
export page, and clicking Go. Then I have to respond to a couple of
dialog boxes from the browser to save the export to a file.

I'd like to be able to run something from a batch file to create a
snapshot in a single step. Any suggestions?
