Continuous replication failover and failback

Typically, the source cluster drives a replication session. However, in some situations, it may be useful for the target cluster to drive the replication session. Access Appliance supports a failover and a failback feature for continuous replication. This feature enables control of replication to be temporarily relocated from the source cluster to the destination (target) cluster.

Continuous replication failover and failback is useful for:

  • Planned failover

    In cases where the source cluster is taken down for routine maintenance or for moving applications to another cluster, a planned failover procedure is available for moving replication from the source cluster to the target cluster.

  • Disaster recovery

    In cases where the source cluster fails unexpectedly, an unplanned failover procedure is available for moving replication to the target cluster.

With failover and failback, you can use the replication continuous failover command to move control from the source cluster to the target cluster. You use the replication continuous failback to restore control to the source cluster.

Continuous replication failover does not automatically move the NFS or the CIFS share information that is associated with file system from the source cluster to the target cluster. Share information has to be done manually.

CIFS shares should be removed before failover and failback operations. After failover and failback operation are complete, add the CIFS shares again.
