Continuous Access XP and TrueCopy® for z/OS
You can use the Continuous Access XP and TrueCopy for z/OS data duplication features to create copies
of logical volumes in two different arrays at remote locations. You can perform Continuous Access XP
operations for UNIX/PC server-based data using the licensed Continuous Access XP or RAID Manager XP
on a UNIX/PC host. TrueCopy for z/OS operations can be performed using the TrueCopy for z/OS
remote console software and can also be managed using TSO and/or ICKDSF commands.
Continuous Access XP provides synchronous and asynchronous copy modes. Continuous Access XP
Synchronous provides volume-based, real-time data backup. Continuous Access XP Asynchronous
provides volume-based, data backup at another time from host-requested write operations to prevent an
increase in response time to the host. Continuous Access XP Synchronous operations support disaster
recovery in a three data center (3DC) configuration with Continuous Access XP Journal operations. See
” Combining Continuous Access XP Journal with Continuous Access XP (3DC cascading configuration) ” on
page 64 for more information.
