Continuous Access XP Journal to create a PiT copy of data volumes belonging to a journal group.

2. After all write I/Os to primary data volume have stopped, split the mirror (that is, a pair of the master

page 103. On the Pairsplit-r pane, specify Group for Range, and specify Flush for Suspend Mode.

volumes is complete. If desired, restart your business application at the primary site to resume business
activities.
