This BRBACKUP command option sets the compression mode. If you specify this option, you can compress your data files before the backup runs.
Syntax
-k|-compress no|yes|hardware|only
Default value: no (no compression)
Possible values:
yes: specifies software compression.
hardware: specifies hardware compression. The prerequisites are that the tape device must support hardware compression and hardware compression must be active. See Hardware Compression.
only: determines the current compression rate of the individual data files. In this case, no backup is started. If you use tape devices with hardware compression, we recommend that you repeat this procedure about once a month. For more information, see Hardware Compression for BRBACKUP.
