Failover Groups

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

Supported operations

Amazon

  • Failback

  • Planned failover

  • Unplanned failover

Azure

  • Failback

  • Planned failover

  • Unplanned failover

Hyper-V

  • Failback

  • Planned failover

  • Test boot

  • Undo failover

  • Unplanned failover

Oracle Cloud Infrastructure

  • Failback

  • Planned failover

  • Undo failover

  • Unplanned failover

VMware

  • Failback

  • Planned failover

  • Point-in-time failover

  • Reverse replication

  • Test boot

  • 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.

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.

  • For Oracle Cloud Infrastructure destination sites, use Undo failover instead of Failback.

  • 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.
