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.

Prioritization and source-nonspecific based virtual machine recovery apparatuses, methods and systems

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 backup configuration request to configure backups of a data storage volume of a source device is obtained. A paired backup device is determined. A recovery prioritization index is generated by determining a recovery priority ranking for each selected for backup data block of the data storage volume. A discrepancy hash for each selected for backup data block of the data storage volume that is available from at least one of a set of source-nonspecific locations is precalculated. The recovery prioritization index and the discrepancy hashes are periodically updated to account for data block use. Backup data including at least one of the recovery prioritization index and the discrepancy hashes is sent from the source device to the backup device.

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.
