This action will power off VM replicas running on target hosts and roll back to the state of VMs before failover. For more information on the undo failover operation, see the Veeam Backup & Replication User Guide.
If the undo failover process encounters an error while being performed, it will not be halted automatically. The plan will proceed until the process is complete.
You can use the Halt option to terminate the undo failover process manually. For more information on stopping a PROCESSING failover plan, see Halting Failover.
You can use the Undo option to resume the undo failover process again.
To perform an undo operation for a plan in the FAILOVER state:
- 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 Enter Credentials step, re-type Site Administrator or Failover Plan Author password.
- At the Summary step, review configuration information and click Finish.
By design, during the undo failover process all plan steps will be skipped, except the Process Replica VM step. This information will be displayed in the Plan Execution Report output.
