The variable factor does not seem to be defined in case the for loop on line 18 is not entered. Are you sure this can never be the case?

The variable suffix does not seem to be defined in case the for loop on line 18 is not entered. Are you sure this can never be the case?

    d = ZipBackup(directory, destination, compress_level=i).backup()
