Disaster Recovery Operations and Failover Groups

Updated

Failover groups provide access to disaster recovery (DR) operations for a group of virtual machines (VMs), based on replication to a DR site (also called destination site or secondary site).

Supported Recovery Targets

You can perform the following operations for the supported recovery targets.

Recovery target

  • Test failover

  • Undo failover

  • Undo test failover (array replication only)

  • Unplanned failover

Operations

You can perform the following operations for failover groups:

  • Failback: Switch back to the primary site after a failover.

  • Planned failover: Switch to a DR site for maintenance of the primary site.

  • Point-in-time failover: Select a point-in-time recovery point to use for a failover operation. You can perform this operation only on the Replication Monitor.

  • Reverse replication: Replicate updates from a VM running on a secondary site to the primary site. You can perform this operation only on the Replication Monitor.

  • Test boot: Validate replicated VMs.

  • Test failover: Validate a group of VMs.

  • Undo failover: Discard changes from the secondary site and make the original source VM active. You can perform this operation only on the Replication Monitor.

  • Undo test failover: Discard changes from the secondary site.

  • Unplanned failover: Make the DR site active in an emergency. After a failover, you can perform a failback operation to return operations to the primary site.

  • View test failover VMs: View the test failover DR sites.

The test failover and the test boot operations can be used to verify that replicated VMs are in good shape. For convenience, you can schedule these operations.

Considerations

Review the following considerations before performing any failover group operations:

  • For replicated VMs using source snapshots, failback operations are supported only when replication is configured in the Command Center.

  • To perform failover, test boot, and failback operations for VMware destination sites, VMware tools must be installed on the source VMs before replicating the VMs.
