Figure 21 on page 82 through Figure 24 on page 84 show the various URz/SIz configurations which
share volumes.
• URz/SIz configurationswhich sharethe URzprimary data volumeand SIz S-VOL
Figure 21 on page 82 shows an example of a URz primary data volume which is also functioning as
aSIz S-VOL. This configuration allows you to use SIz for on-site data backup in case of a URz failure,
and to use URz to provide remote backup of the SIz S-VOL in case of a SIz failure.

Business Continuity Manager allows you to set the starting time of backup copy to journal groups. In the
above configuration, if you set the starting time of 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 subsystems, you can set the same starting time of backup
copy to all the journal groups. If you do this operation, the primary data volumes will be backed up
across themultiplestorage subsystems at thesametime.
