When compressing a tar archive all files in the archive are compressed as a whole, i.e. you can only specify a compression ration for the whole archive and not just for a single file. Technically a tar.bz2 is actually a aggregation of multiple files into a single tar file, which is then compressed. This is different to e.g. PKZip in which each file is compressed individually and the compressed files are then merged into an archive. The first method has better compression ratio, since redundancies among files are compressed, too, whereas the latter is better if you need random access to the individual files.
