Data Compression: (-Z)

Software based data compression is specified using the -Z option. In addition to allowing more data to be stored in a smaller space, using compression in software can provide a performance improvement if the backup device used does not offer hardware compression. However, if you are writing to a locally attached backup device that does offer hardware compression, do not use BRU’s software compression. Hardware compression will always be more efficient than software compression and sending compressed data to a compression-enabled backup device can result in the backup becoming larger, rather than smaller.
