Abstract
A Fiber Channel circuit (150) has a Fiber Channel switch (152) that receives data frames on input ports (142) and writes the frames to a data storage device (158) from an output port (156) A port server (162) backs up the frames to a data storage backup device (160) by reading data volumes from the data storage device (158) and writing backup copies of at least some of the read data volumes to the data storage backup device (160) A data monitor (166) receives the frame data from the output port and applies it to the data storage device (158) The data monitor (166) also applies it to the port server (162) The port server (162) identifies frames in the volume that have been changed during the backup process. The identified frames are either reread from the data storage array (158), or from a memory (168) associated with the port server (162), and written to the data storage backup device (160).
