If Tom is right and the issue is end-of-line transformation, in theory
you might be able to un-mungle newlines. The chances of \r\n occurring
naturally in a tiny backup like that are not huge, so any \r\n in the
data probably used to be a raw \n. Taking a copy of the DB and
performing that substitution might get you a usable backup file.
That's replacing all \x0d\x0a sequences with \x0a. Or I might be wrong
and it's \x0d.
This won't work on a larger backup where some \r\n sequences will occur
naturally in compressed binary data. In those you're likely to have a
much, much bigger job ahead of you.
