Abstract:
For disaster recovery involving a first site and a disaster recovery site, where at least a portion of management service metadata not isolated within the management service, a failover process is initiated, including creating an initial snapshot of the distributed metadata state. In a failback process, a representation is created of state changes for the management service and a delta description is calculated therefrom. The delta description is transmitted to the first site; and a reverse replica is created, at the first site, of all the workload components from the disaster recovery site. The delta description is played back to restore a distributed metadata state that existed in the disaster recovery site and to re-create it in the first site.
