Deja Dup restore not working

Hi!
I am working on a Linux Mint 19.1 Cinnamon machine. Before upgrading to 19.1 I made a full, non-encrypted Deja Dup backup of my complete Home folder on a separate disk.
Now, when I try to restore the data, to adifferent location, I get an error after a long time of "Preparing":
Wiederherstellung fehlgeschlagen
Mit unbekanntem Fehler fehlgeschlagen
Details:
Traceback (innermost last):

 ReadError: unexpected end of data

I have tried the "worst case instructions" for manual untar, but that gives me about 10 000 files which I would need to reconstruct using the "cat" procedure. But I am over 70 years old, I will not live long enough to do that.

Does anyone know what else I can do?
