Performing VMware instant recovery enables you to replace a corrupt or failed virtual machine. When you select a recovery point, the appliance uses data from the recovery point to create a disk image on the appliance and a new virtual machine on the datastore of the ESX server. As soon as the virtual machine is created, it is available for use. The Unitrends appliance utilizes Storage vMotion to copy the data from the disk image on the Unitrends appliance to the target ESX server. Once the migration is complete, the disk image is no longer needed on the Unitrends appliance and it can be torn down. For details, see Performing VMware instant recovery. For information on recovery points, see Types of restores.
The diagram below illustrates the instant recovery process:
