An incremental dump includes all of the directories and just the files
that changed.  Any change no matter how small results in the entire file
being sent.

A full dump includes all of the directories and all of the files.

Adding support for an 'rdiff' dump format to provide much smaller
incremental dumps is on the roadmap/wishlist.
