No not a ReadyNAS. I also have a Netgear Stora connected with 2 X 2TB drives.

In that case you should be able to back up to your Netgear Stora, have you tried? If so what happened?

The Netgear Stora does not show up in the list of destinations when I set up the backup.

Try Windows/NAS and enter the I.P. address of the stora as the host and the sharename in the path.
