Abstract

A method, computer program product and computer system are provided. A processor receives a host input/output write operation, wherein the host input/output write operation includes host metadata regarding data represented by the host input/output write operation. The processor stores the host input/output write operation in one or more physical storage data units. A processor assigns a priority to the one or more physical storage data units. In response to receiving a host volume delete command associated with at least one of the one or more physical storage data units, a processor prioritizes data units of the host volume for deletion based, at least in part, on the assigned priority of the data units of the host volume, wherein data units with a lower priority are permanently deleted before data units with a higher priority.
