SSR 2013 Need Help Setting Up To Multiple USB Destinations

Hi All,

I am trying this software out for a client and looking for some help on the best way to set it up.  Here is what we want to achieve:

1x Server to backup

3x 1TB USB drives to rotate for backups

Basically we want the server to be backed up daily as long as any one of the drives is connected.  Similar sort of option to the built-in Windows Server option where you can create a backup drive pool.  I have looked through the user guide but couldn't pinpoint anything helpful there (I may have missed it?)

Thanks in advance
