Continuous Access XP and TrueCopy® for Mainframe
You can use the Continuous Access XP and TrueCopy for Mainframe data duplication features to create
copies of logical volumes. 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
Mainframe operations can be performed using the TrueCopy for Mainframe 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, real-time remote data replication to prevent an increase in response time to the
host. At longer distances, Continuous Access Asynchronous XP remotely replicates data which is also in
order, but may be a few I/Os behind. Continuous Access XP Synchronous operations support disaster
recovery as part of a three data center (3DC) configuration in combination with Continuous Access XP
Journal. See Combining Continuous Access XP Journal with Continuous Access XP (3DC cascading
configuration) for more information.
