Patent abstract

Described are techniques used in performing data replication processing. Data is replicated on a recovery site from a production site. When a disaster occurs, the state of the replication processing is determined and a restart copy of the data is made available from the recover site. Processing continues based on whether protection mode is desired such that the system executes using the recovery site as the restart with a replicated copy of the data. Data is propagated from the recovery site to the production site to resume operations and replication processing originating from the production site.
