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. -- PMM
