The Undo Failback action powers on VM replicas running on target hosts and switches from the production VMs back to the VM replicas — as a result, the plan acquires the FAILOVER state. For more information on the undo failback operation, see the Veeam Backup & Replication User Guide, section Undo Failback.
To perform an undo operation for a plan in the PREPARE FOR FAILBACK or FAILBACK state:
- Navigate to Recovery Plans.
- Select the plan. From the Launch menu, select Undo.
Click the plan name to switch to the Plan Details page, and click Undo.
- Complete the Undo Plan wizard:
- For security purposes, at the Credentials step, retype your password.
- At the Summary step, review configuration information and click Finish.
If the undo failback process encounters an error while being performed, it will not be halted automatically — the plan will proceed until the process completes. To terminate the undo failback process manually, use the Halt option to stop the currently running plan as described in section Halting Failover. To resume the undo failback process again, use the Undo option.
