DECLUSTERED RAID POOL AS BACKUP FOR RAID VOLUMES

摘要

Storage data is distributed across a first plurality of physical disks in a first enclosure using at least one redundant array of independent disks (RAID) technique. This creates a plurality of virtual volumes. This plurality includes at least a first virtual volume and a second virtual volume. The storage data is copied (i.e., backed up) to a second plurality of physical disks in a second enclosure. The storage data in the second enclosure is distributed across the second plurality of physical disks according to a declustered RAID technique. The declustered RAID allocations each correspond to the virtual volumes created in the first enclosure.
