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