Disaster recovery of volumes and file systems using Volume Replicator (VVR) and Veritas File Replicator (VFR)

In a disaster recovery scenario, you can achieve volume and file level replication by configuring VVR and VFR respectively. Storage Foundation (SF) configured on the hosts provides storage to the guest virtual machines.

VVR and VFR replication technologies replicate volume block devices and file system respectively on the DR site with applications in active state. When the primary site goes down or a network disruption occurs, the VCS Global Cluster Option (GCO) configured for the primary and DR site provides coordinated failover of applications. The DR site takes over the VVR and VFR primary role.

In case you want to move back to the original primary for VVR replication, perform a role transfer. VCS GCO provides the option to select the primary VVR site after a network partition while the applications remain active.

For more information on setting up VVR and VFR, refer to the Veritas InfoScale™ Solutions Replication Administrator's Guide.
