Back up of Mycloud Home to an external device

On the my cloud home device there is a usb port available.
But that usb port is only for import data to the my cloud home device.

It is really strange that export by using the USB port is not available!
Users always want to make a backup of the data on the my cloud home device to another external device.
Now all the data is put on the my cloud home device and there is no other way to make a copy of the data using WIFI!

Make the export functionality for the USB port available, so people can backup their data!
Now the My cloud home device is not a good product
