Cron Jobs For Exporting Datafeeds & Backup

In my cpanel I am trying to set a cron job that will under datafeeds, google export to server twice a day. I have found the following line which does not do anything. Not sure if MYPASS is actually set to something different.



php /var/www/public_html/admin.php --dispatch=exim.cron_export --cron_password=MYPASS



I have tried replacing the path to the url and get these sort of errors:

/usr/local/cpanel/bin/jailshell: -c: line 0: unexpected EOF while looking for matching `"'

/usr/local/cpanel/bin/jailshell: -c: line 1: syntax error: unexpected end of file



Once I have done the above I will also like to set up one to backup the database.



Please help!
