This option enables Arcserve Backup to compress files using software compression algorithm before backup. Since most tape devices already provide hardware compression, you may use this option only if hardware compression is not available. Enabling both hardware and software compression is unnecessary, and if both are selected, software compression will be automatically disabled when the job is run.
Important! Arcserve Backup performs local compression and encryption at the agent system. When you specify local compression and encryption and ARCserve server-based compression and encryption (global option), Arcserve Backup performs the compression and encryption at the agent system.
