    摘要: An apparatus, system, and method are disclosed for managing multiple copy versions of a source volume. In one embodiment, the apparatus includes a replication record management module, a pre-pairing record management module, and a copy record module. The replication record management module is configured to maintain a current replication record that is descriptive of a current copy version of the source volume. The pre-pairing record management module is configured to maintain a future pre-pairing record that is descriptive of a future copy version of the source volume. The copy record module is configured to create a copy record from a pre-copy record. The pre-copy record may be either the current replication record or the future pre-pairing record. The apparatus, system, and method beneficially maintain multiple records to describe different states for a particular copy version and dynamically handle changes to a source pool, a target pool, or both in a data copy environment.

    摘要: An apparatus, system, and method are disclosed for recovering multivolume data. In one embodiment, a backup module physically backs up a plurality of source volumes to plurality of backup volumes. A data set size module may also capture a data set size for a data set during the physical backup. A retrieval module retrieves metadata for the data set from a catalog. A location module locates the data set on the plurality of backup volumes using the metadata. A recovery module recovers the data set as a recovered data set from the plurality of backup volumes. In one embodiment, a verification module verifies that the recovered data set is successfully recovered.

    摘要: A method for using a change-recording feature to perform more effective backups includes generating an initial point-in-time copy of source data residing in a storage device. The method may then perform an initial backup of the initial point-in-time copy. As changes are made to the source data, the method may record changes made to the source data after the initial point-in-time copy is generated. These changes may be stored as incremental change data. At some point, the initial point-in-time copy may be updated using the incremental change data. In order to perform an incremental backup of the updated point-in-time copy, the method may query the incremental change data to determine which changes were used to update the point-in-time copy. The method may then perform an incremental backup of the updated point-in-time copy by backing up the changes designated in the incremental change data.
