Failback undo is one of the ways to finalize failback. When you undo failback, you confirm that the VM to which you failed back (the production VM) works in a wrong way and you want to get back to the replica.
The undo failback operation is performed in the following way:
- Veeam Backup & Replication powers off the production VM.
- Veeam Backup & Replication reverts the replica to its pre-failback state.
- Veeam Backup & Replication powers on the replica and changes the replica state from Failback to Failover.
