撤销故障切换

Failover undo is one of the ways to finalize failover. When you undo failover, you switch back from a VM replica to the original VM. Veeam Backup & Replication discards all changes made to the VM replica while it was in the Failover state.

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 latest restore point in the replication chain. Changes that were written to the protective virtual disks (<disk_name>-interim.vmdk) while the VM replica was in the Failover state are discarded.
2. The state of the VM replica gets back to Ready, and Veeam Backup & Replication resumes replication activities for the original VM on the source host.
