3. If the USB backup was gone,

then it somehow didn't get saved in the first place, for some reason the program didn't register it.

I finished a novel recently (my first and last). I started it in Pages. Same thing happened to me, I lost 9 hard-won pages of writing that had been on the screen when I did a Save and then Save As elsewhere. Gone. I left Pages, tried LO as well as two other Word-like apps. Finally paid for Word. Too many tutorials were teaching how to do stuff in Word, which, no longer being the computer whiz I used to be, did me no good.

Anyway, my sympathies for the loss. Put it in two different apps altogether in the future before closing up?
