I had trouble on a Nook HD and kept getting a 0 byte file. Then I noticed the nook had a full screen diaglog that had 2 buttons at the bottom of the display, one of which was to perform the backup. This was complicated by the top of the screen by a request for the key to unlock the device encryption, which I had trouble figuring out how to specify no key. I fumbled around starting from scratch a few times and finally the "do backup" button got enabled and I tapped it, resulting in a 41 byte file. Unfortunately, I the calibre dialog to import the key failed, claiming no file selected even though I went through all the steps to import a key, including selecting the file and clicking open.
