Error on Database Backup

[myjeeprocks]

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /httpdocs/photopost/adm-backup.php on line 45

Can anyone translate this for me? Trying to back up the database from the control planel for an upgrade. Thanks.

Have you in global options set a backup path and location to mysqldump in the settings?

Just an FYI if mysql is located on an external server you cant use the backup utility.
