Each one # corresponds to a drastically different dump format. The first on is # the original dump format on a 4.1 BSD or earlier file system. The # second marks the change between the 4.1 file system and the 4.2 file # system. The Third marks the changing of the block size from 1K # to 2K to be compatible with an IDC file system.
