ABSTRACT:
An embodiment of the invention provides a method for improving efficiency in a system containing repeated snapshots of an original data store. A READ/WRITE enabled parent virtual logical unit (VLU) to store an original data store is created. One or more READ-only enabled child VLUs, each storing a point-in-time copy of the original data store, are created at distinct times. A search pointer and a propagation pointer are implemented on the parent VLU and on each child VLU. The search pointer of each child VLU is set to point to the next subsequently created child VLU, with the search pointer of a most recently created child VLU set to point to the parent VLU. The propagation pointer of each child VLU is set to point to the immediately previously created child VLU, with the propagation pointer of the parent VLU set to point to the most recently created child VLU.
