I have the normal NAS drive with a USB drive. The USB drive have got a extra release in the network. But I can’t do a backUp with an assignment. Like I can do with the intern drives. To make a backup I have got a second USB drive on the nas!
There is no menu point “USB to USB” only “NAS to USB” and “USB to NAS”
I hope you can make the point “USB to USB” then I can backup my whole NAS!
