Setting Up Remote Replication for Disaster Recovery (BUI)

A two-system disaster recovery site consists of a source appliance at a production site and
a target appliance located at a recovery site in a geographically different location. In the
event of a catastrophic production site failure, the administrator redirects client operations to
the recovery site by reversing replication on the target appliance, thus ensuring continuous
operation. After the production site is restored to normal operation, the administrator updates
the production site by reversing replication at the recovery site. To restore the original source-
target relationship, replication is then reversed again.

Setting Up a Target Appliance at a Recovery Site
(BUI)
To create a replication target for disaster recovery:
1. Identify a target appliance at a recovery site.
The target appliance requires a software version compatible with the source appliance. See
MOS Doc ID 1958039.1 for details.
From the source appliance, create a target as described in
