Universal Replicator for Mainframe/ShadowImage for Mainframe configurations which share
the Universal Replicator for Mainframe primary data volume and ShadowImage for Mainframe
S-VOL
The following figure shows an example of a Universal Replicator for Mainframe primary data
volume which is also functioning as a ShadowImage for Mainframe S-VOL. This configuration
allows you to use ShadowImage for Mainframe for on-site data backup in case of a Universal
Replicator for Mainframe failure, and to use Universal Replicator for Mainframe to provide
remote backup of the ShadowImage for Mainframe S-VOL in case of a ShadowImage for
Mainframe failure.

Business Continuity Manager allows you to set the starting time for the backup copy to journal
groups. In the above configuration, if you set the starting time for the backup copy, the writes to
the primary data volume up to that time will be backed up to the secondary data volume. If the
above configuration is used in multiple journal volumes in multiple storage systems, you can set
the same starting time for the backup copy to all the journal groups. If you do this operation, the
primary data volumes will be backed up across the multiple storage systems at the same time.

Universal Replicator for Mainframe/ShadowImage for Mainframe configurations which share
the Universal Replicator for Mainframe secondary data volume and ShadowImage for
Mainframe P-VOL
The following figure shows an example of a Universal Replicator for Mainframe secondary
data volume which is also functioning as a ShadowImage for Mainframe S-VOL. This
configuration allows you to use ShadowImage for Mainframe to provide multiple backup
copies of a single Universal Replicator for Mainframe primary data volume.
