hi
i would recommend getting phpMyAdmin. It is pure magic and FREE, to quote them:
"phpMyAdmin 2.9.0.3 is released
Welcome to phpMyAdmin 2.9.0.3, a tool written in PHP intended to handle the administration of MySQL over the Web. Currently it can create and drop databases, create/drop/alter tables, delete/edit/add fields, execute any SQL statement, manage keys on fields." .... and do backups!
see their website
http://www.phpmyadmin.net/home_page/index.php
check with your host if they don't have it installed
hope this helps
regards
