Abstract
A method, system, and apparatus of minimizing configuration of changes in a fabric-based data protection solution. In one embodiment, a method includes configuring a switch such that a write request to a primary storage device is transferred through a virtual initiator in the switch to the primary storage device and to a secondary storage device, and configuring the switch such that a read request from the secondary initiator of a data in the primary storage device appears as though the read request is coming from a physical initiator rather than the secondary initiator (e.g., such that system protocol may be bypassed because the switch intercepts a response having the data from the primary storage device through a virtual target which uses the virtual initiator of the switch to communicate the data to the secondary initiator rather than the physical initiator).
