Undo Failover

To revert a VM replica to its pre-failover state, you can undo failover.

When you undo failover, you switch back from the VM replica to the original VM. Veeam Backup & Replication discards all changes made to the VM replica while it was in the Failover state. You can use the undo failover scenario if you have failed over to the VM replica for testing and troubleshooting purposes and want to get back to the normal operation mode.

The undo failover operation is performed in the following way:

  1. Veeam Backup & Replication reverts the VM replica to its pre-failover state. To do this, Veeam Backup & Replication powers off the VM replica and gets it back to the state of the latest snapshot in the snapshot chain. Changes that were written to the snapshot delta file while the VM replica was in the Failover state are discarded.
  2. The state of the VM replica gets back to Normal, and Veeam Backup & Replication resumes replication activities for the original VM on the source host.
