[morrow]

my db is around 65/mb and I searched high and low for the utility you're looking for. Just modify this file as needed and run from cgi-bin.

good luck.

#!/bin/sh
#
# Edit this file and put correct string for following items
# MYSQLUSERNAME1&2 MYSQLPASSWORD1&2 mysqlXX1&2 DATABASE_NAME1&2
#
# Don't forget to set permission of 700 (not 755) to this script.
# You can do that with WebFTP, SiteTools, most FTP software, other utilities.
#

echo # Send text/plain Content-type header.
exec 2>&1 # Senf error output (stderr) to the browser

filename=${HOME:-${DOCUMENT_ROOT%/*}/cgi-bin/filename.sql} # ex.: dbbackup_2006-03-07.sql
#echo "Moving MySQL db"
# Dump DB
#/usr/local/bin/mysqldump --opt --no-create-db --user=xxx --password=xxx --host=xxx vbulletin > $filename

#echo "Data saved in $filename.
#Now importing to the destination DB"

# Restore (import)
/usr/local/bin/mysql --user=xxx --password=xxx --host=xxx xxx < $filename

echo 'Done'

Call the file whatever you want with a .cgi extension.
