A system and method of transporting volumes of information from one host
computer system to another using point-in-time copies of LUNs but wherein
the hardware provider does not necessarily understand the volume
configuration of the data. The system and method involves an intermediate
layer, i.e., a point-in-time copy interface layer that communicates with
both a requesting host computer system and a hardware provider to enable
the transfer of volumes of information without requiring that the
hardware provider understand the volume information.
