How screwed am I? (corrupt backup files?)

[Stumpy]

I have a bunch of backups... all in one place... and it seems most of
them have been borked in some way. I have tried to restore 50gb backups
using qube manager and end up with empty appvms (that show a size of 0mb
in qubes manger and as far as i can tell are empty when i start them up
and look in them), though with many of the restores I dont get errors?

I am trying to figure out how to restore them manually per the qubes
emergency restore doc page and am getting errors like:

[user@disp9624 appvms2salvage]$ sudo tar -i -xvf
qubes-2019-12-14T162028_shuttle -C ~/Templates/

Can someone explain how bad things are looking from these errors?

If you haven't already, try fully patching the Qubes OS where you are
attempting the restores.
