Note that is also possible to use dump or cpio as well.  Unlike the
MS-Windows zip/unzip, which combines compressing and archiving in a
single program, the 'UNIX' way is to separate these functions.  bzip2
only compresses.  Other programs (tar, dump, cpio) create archives -- 
bundle a group of files and/or directory trees into a single file.
