Abstract
A differencing virtual hard disk is created at a recovery server. The differencing disk is pointed to a virtual machine that has been backed up to a backup media server. A configuration file associated with the backed up virtual machine is restored to the recovery server while the backed up virtual machine remains on the backup media server. A planned virtual machine is created from the configuration file. Virtual hard disk settings of the planned virtual machine are modified to point to the differencing disk at the recovery server. Parameters of the planned virtual machine are modified based on a path of the configuration file as restored on the recovery server. The planned virtual machine is realized.
