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.
