US Patent 10055309 Parallel restoration of a virtual machine's virtual machine disks

Parallel restoration of a virtual machine's virtual machine disks is described. A system identifies restoration parameters for restoring multiple virtual machine disks associated with a virtual machine. The system identifies multiple available threads in an image proxy appliance that are sufficient for parallel restoration of each of the multiple virtual machine disks. Each of the multiple available threads restores a corresponding virtual machine disk as a corresponding dummy virtual machine, based on the restoration parameters. The system attaches the multiple dummy virtual machines to the virtual machine as the multiple virtual machine disks.
