I am speaking under correction, but I am sure the "Copy" functionality is a licensed feature. So if you are not running in eval mode, nor bought the license, it will not be possible.
What you can do is to run the "Copy Media Server Configuration" using the BEUtility in the Symantec\backup exec\nt directory.
Add the Server you want to copy off, and the Server you want to copy to as Media Servers within the BEUtility.
Select the Server which you want to copy the config from, and select "Copy Media Server Configuration". Add your domain\backupaccount, password, and a target location.
Once the file has been created, select your "other" Media Server and apply the config file you just created.
This will copy all your policies, selection lists, and the jobs.
Open and close Backup Exec.
Hope this helps.
