Business Copy Z primary volumes
Configurations with Business Copy Z secondary volumes
The following figure shows a Business Copy Z primary volume used as the production volume. A
remote Continuous Access Journal Z backup copy is made of the Business Copy Z secondary

Access Journal Z operation.
You can make a Business Copy Z backup copy at a specified time without suspending the
Continuous Access Journal Z pair on the secondary system. See
