Your Incrementals will be much faster following your FULL image due to the fact that they are only imaging the CHANGES in your System since the last image taken... they are usually very small. Whenever you look at those images, they will be a combination of all images taken in that image chain, including the full.
Image chains start with a FULL image and create difference images along the way depending on what type of image is taken. A DIFFERENTIAL includes all changes since the last FULL, an INCREMENTAL includes all changes since the most recent image (Full, Differential or Incremental). A new chain will begin at each new FULL.
