Failover undo is one of the ways to finalize failover. When you undo failover, you switch back from a vApp replica to the original vApp. Veeam Backup & Replication discards all changes made to the vApp replica while it was in the Failover state.
The undo failover operation is performed in the following way:
- Veeam Backup & Replication reverts the vApp replica to its pre-failover state. To do this, Veeam Backup & Replication powers off the vApp replica and gets it back to the latest restore point in the replication chain.
- The state of the vApp replica gets back to Ready, and Veeam Backup & Replication resumes replication activities for the original vApp on the source host.
