DYNAMIC CONSISTENCY GROUP FORMATION AND SYSTEMS USING THE SAME

In one embodiment, a system, includes logic for creating a snapshot of first data stored on a source storage system, wherein the snapshot is a logical copy of the first data stored on the source storage system with respect to data content and data structure; logic for copying the snapshot to a target storage system; logic for copying the first data represented by the snapshot from the source storage system to the target storage system; logic for detecting one or more write operations affecting data on the source storage system; logic for detecting one or more collisions affecting the first data on the source storage system, logic for setting a consistency group interval; and logic for altering the consistency group interval to minimise collisions affecting data on the source storage system. Other systems and computer program products for dynamic consistency group formation are also described.
