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) and changes sent to it during failback work 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.
