NPS-10 does not have upload function, i.e., upload data to the memory cards.
If you want to have secondary copy, you can connect USB hard drive or USB card reader to the USB port, and select 'USB HDD' on the LCD.
Then you can choose to do 'SYNC' at the menu.
SYNC is synchronizing the backup folder in internal drive to the external USB drive.
It copies every backup folder inside internal disk to the external USB drive.
