  21 # Description:
  22 # Verify that compressed send correctly handles volumes
  23 #
  24 # Strategy:
  25 # 1. Write compressible data into a volume, take a snap
  26 # 2. Verify the compressed stream is the correct size, and has the correct data
  27 # 3. Repeat step 2 for an incremental compressed stream
