Abstract
A system and method reduces cleaning overhead in a storage array by establishing owner groups for selectively organizing memory page groups. The method generates a metadata lookup structure to correlate a disk address of the real-time data generated to a logical block address on the select storage volume. Further, the method establishes a current state of the select storage volume as a first owner group that receives reference access to the logical block address associated with the memory page group. The method selectively generates a memory snapshot of the current state of the select storage volume to form a subsequent owner group. Additionally, the method enables the first owner group and the subsequent owner group to reference the logical block address that is associated with the memory page group until a real-time data write provides a new logical block address that is associated with a new memory page group.
