Abstract
The Prioritization and Source-Nonspecific Based Virtual Machine Recovery Apparatuses, Methods and Systems (“MBR”) transforms backup configuration request, restore request inputs via MBR components into backup configuration response, restore response outputs. A restore request to build a recovery virtual machine using a backup disk image of a source device stored on a backup device is obtained. A virtual machine recovery environment comprising a guest virtual machine running a guest hypervisor is booted. A recovery virtual machine configuration identifying source-nonspecific software is determined. A recovery prioritization index for data blocks of the backup disk image is determined. Essential data blocks of the backup disk image are prefetched. An operating system of a nested guest abridged virtual machine is booted. Command data blocks are fetched when a user command is received. Remaining data blocks are fetched in priority order. The nested guest complete virtual machine is migrated to a non-nested guest virtual machine.
