According to the Veeam Backup & Replication user guide1, a failover plan is a set of rules that defines how VMs must be failed over to their replicas1. You can create and run failover plans for regular replicas and CDP replicas1.

After you run a failover plan, you can perform the following actions on it2:

Undo — reverts VMs in the failover plan back to their original state at the production site2.

Start — runs the failover plan again if you need to repeat the failover operation for some reason2.

Edit — modifies the settings of the failover plan, such as adding or removing VMs, changing their order or time delay1.

Delete — removes the failover plan from Veeam Backup & Replication. This does not affect the VM replicas that are used by the plan1.
