USB Backups

I currently have a single 2TB MyCloud gen.1 and looking to get the EX2 Ultra. Reading the manual for the EX2 it mentions USB backup but that looks like folder to folder. I want to backup all the NAS files/folders to the external drive USB connected.

So how would I do that? Is there a way to do incremental backups?

You may, if you haven’t already, want to read or search through the dedicated EX2 subforum where there may be more information/discussion on how the EX2 Ultra can be backed up to a USB drive.
