22# Description:
23# Verify that the amount of data in a send -c stream matches compressratio.
24#
25# Strategy:
26# 1. For random compression types, and compressible / incompressible data:
27# 2. Create a snap with data
28# 3. Compare the size of the stream with the data on the dataset, adjusted
29#    by compressratio for normal send, and compared to used for send -c.
