NetBackup - backup staging for DR

Hi,

I have a NetBackup 5220 appliance which works as Master and Media server at main site and another media server at DR site.

I'm looking to set up a basic disk staging unit for staging backup copies to DR media server.

My questions are;

1) If I click Staging Schedule and check Destination, I only see Master/medis server's storage unit as final destination.

    I would like to simply have another copy to DR site, so in case of disaster, I would like to quickly set up a master server at DR site and recover catalog.

    In this case, can I just use Multiple copies and configure two copies (Copy 1 for primary master/media unit, copy 2 for media server at DR site?

2) Is this a plausible solution? As I can't get another appliance for setting up Advanced disk/Puredisk at DR site for SLP/AIR. Basic disk staging would be my only viable solution at the moment.

Thanks
