Backburner dispatches rendering to Autodesk Backburner(TM), Autodesk's
distributed network rendering solution. As for Background rendering,
you can use Composite while rendering proceeds. When you choose
Background or Backburner rendering, the render is done on a copy of the
composition: modifying the composition while it renders will not affect
the result of the rendering.
6 Click the Render Actions button to dismiss the Render dialog, and display
the Render Actions tab in the Project Preferences dialog. This allows you
to edit the existing render actions, or define new ones.
7 Set the Start and End values to set the start and end frames for this render.
8 Click the Reset button if you wish to modify the Start and End frames to
include frames of all the currently selected outputs.
9 Finally, click the Start button to begin rendering, or click the Cancel
button.

Caching
Composite can keep track of previously-computed images through an image
cache, called the media cache. While building your composition, you will
frequently connect new nodes to the output of existing nodes. It is beneficial
for performance to avoid re-computing the image results of existing nodes,
and rather read previously-computed results from a cache.
Composite supports this through its media cache, which features two caching
levels: an automatically managed in-memory cache, which is limited by the
size of available memory, and a disk-based cache that you can turn on per
node.
