About Failback for Virtual Machines to the Source Site
Native failback of virtual machines that you have previously recovered in vCloud Air is available by using
vSphere Replication.
After successfully recovering your replicated virtual machines in vCloud Air, you can failback those virtual
machines. In the vSphere Replication, you can configure reverse replication, which repoints the replication
of the virtual machines back to your on-premises vSphere environment. In the event of a disaster you would
failover all your virtual machines from your on-premises data center to the vCloud Air Disaster Recovery
cloud. Once you have restored on-premises data center, native failback provides you with the ability to
restore your service from the cloud back to your on-premises data center.
NOTE To use native failback you must power-off the virtual machine before you copy it. You can start
multiple copies simultaneously and run them in parallel.
