    If a tenant wants to resume operation of a production VM, he or she can fail back to it from a VM replica on the cloud host. When you perform failback, you get back from the VM replica to the original VM, shift your I/O and processes from the cloud host to the source production host and return to the normal operation mode.

    A tenant can perform failback to a production VM after partial site failover or full site failover. If a tenant performs the failback operation after full site failover, he or she needs to process every VM in the cloud failover plan individually.

    If a tenant managed to restore operation of the source host at the production site, a tenant can switch from the VM replica to the original VM on the source host. If the source host is not available, a tenant can restore the original VM to a new location and switch back to it. To learn more, see the Replica Failback section in the Veeam Backup & Replication User Guide.

    Failback to production is a temporary stage that should be further finalized. After a tenant tests the recovered original VM and make sure it is working without problems, he or she should commit failback. A tenant also has an option to undo failback and return the VM replica back to the Failover state.
