  21 # Description:
  22 # Verify that the -c and -D flags do not interfere with each other.
  23 #
  24 # Strategy:
  25 # 1. Write unique data to a filesystem and create a compressed, deduplicated
  26 #    full stream.
  27 # 2. Verify that the stream and send dataset show the same size
  28 # 3. Make several copies of the original data, and create both full and
  29 #    incremental compressed, deduplicated send streams
  30 # 4. Verify the full stream is no bigger than the stream from step 1
  31 # 5. Verify the streams can be received correctly.
