Abstract

A method, computer program product, and computing system for hot recovery of virtual machines are described. The method may include initiating a recovery process to transfer data, from a backup archive of a virtual machine to be restored, to a virtual disk at the virtual machine host computer. The method may further include booting the virtual machine to be restored. The method may also include intercepting a read request from the virtual machine to the virtual disk at the virtual machine host computer. The method may additionally include determining if the read request from the virtual machine requested data from the virtual disk which has not yet been restored from the backup archive to the virtual disk by the recovery process. Moreover, the method may include, in response to determining that the requested data has not been restored from the backup archive to the virtual disk, returning the requested data.
