This BRBACKUP command option sets the compression mode.

Input syntax: -k|-compress no|yes|hardware|only

Default value: no (no compression)

If you specify this option, you can compress your data files before the backup is performed.

·        yes: Software compression.

·        hardware: Hardware compression. Prerequisite: the tape device must support hardware compression and hardware compression must be active. See Hardware Compression.

·        only: Determine the current compression rate of the individual data files. In this case, no backup is started. If you use tape devices with hardware compression, SAP recommends repeating this procedure about once a month. For more information, see Hardware Compression for BRBACKUP.
