Unsure what you mean, sorry 
I have never noticed backup functionality there.
The swipe that gives me the shortcuts has sometimes shown an empty page, but it’s not something I’ve seen often enough to file a bug report about, and might not even be current anymore. That’s the only place I would imagine has that.
Copying manually when I have videos from the Jolla 1 days on my phone is too painful, even with the excellent File Browser.
Here’s how I deal with it:
I installed the Fish shell, and tmux, and made tmux switch shells to fish.
Then a form of this rsync -avz . /run/media/ defaultuser/UUID/backup/ --progress --info=progress2
I’ve been less than great with periodic rsync baclups to my NAS, not least because I don’t want to pay for the electricity of having it always on, but with this new SD card I could set up a cron job. And try to be more regular with the NAS
