According to one embodiment, a backup is searched for data to be restored from a volume. The backup comprises multiple disks. The volume is stored in one or more spans on the disks. The spans containing the data to be restored from the volume are identified as desired spans, and a current disk is searched for the desired spans. A first subset of data is read from the desired spans on the current disk. A second subset of data is recorded on an unread list. The second subset of data comprises the data to be restored from the desired spans that are not on the current disk. The remaining data is read from the remaining disks according to the unread list. |
