Image recovery from volume image files |
摘要 |
A system for image recovery comprises an input interface and a processor. The input interface is configured to receive a block backup volume that can be mounted. The processor is configured to determine a merged chain map by consolidating one or more incremental chain maps and to store an image using the merged chain map and a volume map. |

1. A system for image recovery, comprising:
an input interface configured to receive a block backup volume that can be mounted; and a processor configured to:
determine a merged chain map by consolidating one or more incremental chain maps, wherein to determine the merged chain map includes:in the event that only one incremental chain map exists, the merged chain map reflects changes included in the existing one incremental chain map, andin the event that a plurality of incremental chain maps exist, consolidating the plurality of incremental chain maps to form a single map,wherein the merged chain map indicates the changes to a full backup that exist in the one or more incremental chain maps before the changes are applied to the full backup in connection with a data recovery process; andstore an image using the merged chain map and a volume map. |
