ABSTRACT:
Snapshot sets comprising snapshot criteria are created, maintained, and executed via a command set designed to facilitate managing and conducting snapshots on data distributed across multiple volumes. Snapshot criteria such as source volume, target volume, redundancy level, copy mode, and the like are added as desired to a snapshot set. Upon invocation of an execute command, the fast replication operations defined by the snapshot set are executed, providing a logically atomic data replication utility potentially involving multiple sources and targets. In one embodiment auto selection of a target may be specified, thus facilitating over-subscription of target resources. The present invention reduces the complexity of archiving data—particularly data distributed across multiple volumes such as data associated with database applications and the like.
