Presumably you're trying to backup a mysql database. In a standard setup the
database files are only accessible to the 'mysql' user. Your webserver, under
normal circumstances, would not be able to access those files. Once you get
over this hurdle, the second problem is that your destination directory is
not writeable by any user other than mysql.
In short you're better off using mysqldump to backup your databases.
