This parameter defines the tape size in gigabytes (G), megabytes (M) or kilobytes (K) used by BRARCHIVE. Use this parameter if different tape stations are addressed with parameters tape_address_arch and tape_address_rew_arch than with tape_address and tape_address_rew. You can then use different tape station types for BRBACKUP and BRARCHIVE without risking a tape overflow.
tape_size_arch = <size>K|<size>M|<size>G
Default value: same as tape_size
