What device turns out to be a SATA HDD?

I find your mail hard to follow. I do not understand what happened.

Do you mean you tried to back up to an external drive, but by mistake,
you backed up *from* your internal hard disk *to* your internal hard
disk? And thereby filled it up?

So, what you are saying is that you accidentally filled up your hard
disk, and now you can't log in? Is that right?

If so: free up some space. Use a bootable USB to delete the misdirected backup.
