Efficient backup and restore of storage objects in a version set |
摘要 |
The version set backup and restore facility responds to a version set backup request by backing up multiple snapshot copies of a storage object concurrently from a storage array to backup storage media. The version set backup and restore facility responds to a version set restore request by restoring a plurality of snapshot copies of the storage object concurrently from the backup storage media to the storage array. The on-tape backup image of the version set includes variable-length extents of data for each of the multiple snapshot copies of the storage object. The variable-length extents of data for each of the snapshot copies of the storage object are grouped together and ordered in the on-tape backup image by increasing or decreasing logical block address. |
