  21 # Description:
  22 # Verify that we can receive a compressed stream into a deduped filesystem.
  23 #
  24 # Strategy:
  25 # 1. Write heavily duplicated data to a filesystem and create a compressed
  26 #    full stream.
  27 # 2. Verify that the stream can be received correctly into a dedup=verify
  28 #    filesystem.
