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 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.
