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 is obtained. A reestablishing virtual machine is booted. A recovery virtual machine configuration identifying source-nonspecific software is determined. A recovery prioritization index for data blocks of the associated backup disk image is determined. Essential data blocks of the backup disk image are prefetched to build a pseudo abridged virtual machine. User access to the reestablishing virtual machine is provided. A latent virtual machine is created inside the reestablishing virtual machine. Command data blocks are fetched for both the reestablishing virtual machine and the latent virtual machine when a user command is received. Remaining data blocks are fetched for the latent virtual machine in priority order. The reestablishing virtual machine is rebooted to boot the latent virtual machine.
