ABSTRACT:
A method for utilizing virtual targets and abstract copy orders in preparing and servicing requests for server-free data transfer operations in a data storage network. The abstract copy orders represent data transfers between virtual targets and real devices. They allow source target copy orders to be prepared separately from destination target copy orders. The abstract copy orders may then be converted into concrete copy orders involving only real device targets for execution by a data mover that implements the server-free data transfer operations.
