Patent ID: 7721057

Claim:
A system for transporting data across a system area network, the system comprising: one or more processors for executing computer executable instructions; and one or more computer storage media storing the computer executable instructions that when executed by the one or more processors provide: a storage subsystem module that stores data for at least one host computer system, the data stored in at least one LUN; a requester module for requesting the transportation of data stored in the storage subsystem, the transportation involving the transfer of information from a first host computer system to a second host computer system, the requester module requesting the transportation of a volume of information stored on at least a portion of one or more LUNs; a point-in-time copy interface module for receiving a request from the requester module and generating an instruction to create a point-in-time copy of the one or more LUNs on which the volume of information is stored, wherein the instruction comprises identification information related to the one or more LUNs on which the volume of information is stored, and wherein the point-in-time copy interface also generates a backup components document describing the volume to be transported; a provider module for receiving the instruction to create the point-in-time copy and creating the point-in-time copy, the provider module providing mapping information to the point-in-time copy interface, wherein the mapping information relates to a location for the point-in-time copy; and an importer module for importing the backup components document and using the information in the backup components document to access the point-in-time copy of the volume to be transported.
