The '-b' option needs a backing_file argument, but the next thing
on your commandline is "-o". The option parser has thus assumed you
meant to say that the backing-file is named "-o", and has then
completely misinterpreted the rest of your commandline as a
result. Delete the '-o', or, if you wanted to specify options, put
"-o whatever-options-you-wanted" somewhere else than between
the '-b' and its argument.
