Failback

1 February 2024

Failback is the process of returning operations from the DR site back to the primary site.

To perform an actual failback:

In SiteContinuity, navigate to DR Plans.
In the Disaster Recovery Plans page, choose a DR Plan for failover. A DR Plan must be in the Failback Ready state for failback.
Click the Actions menu (⋮) of the DR plan, and select Failback. The Failback page displays the target DR site and the target Cohesity cluster:
From the Resource Profile drop-down, select a Resource Profile.
For recovery, the latest snapshot is always used. Confirm the snapshot, click Edit, choose a different one, and click Apply.
Enter YES confirm to confirm and click Failback.

Validate Failback

To validate failback:

Log in to the DR vCenter.
Confirm that the virtual machine instances come up in the specified order as defined in your DR plan.
Ensure the allocated resources and network configurations for each VM are correct.
Verify the functionality of your critical applications to confirm they are working as expected.
Navigate to the primary (DR) Cohesity cluster and validate the Protection Group created as part of the failback process.

Next Steps

If the Failback is successful and your DR plan is in Failback Complete state, you can click the Actions menu (⋮) corresponding to the DR plan in the DR Plans page and perform a prepare for failover to then perform a Test Failover or Failover.

If the failover is partially successful, the DR plan’s status transitions to the Failback Failed state but still gives the option to Force Finish to mark the partial success as a complete success.

If the failover fails, the DR plan’s status transitions to the Failback Failed state. To explore possible causes and resolve the error, see the Troubleshooting section.
