cPanel Automatic Backup Script

I have a script to do automatic backups on cPanel, so i can backup accounts from one server to another but the script does not work, but i believe it is correct as it is a very common script that alot of people use. I have to upload the script to each hosting account so it can backup that account to the server i have specified in the script but it doesnt work. Can someone please fix this for me or create a new one. It needs to do daily backups to my other server and overwriting any old backups.
