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