Method and computer system for information notification

摘要

The present invention allows notification of information held by a first computer to a second computer even if the first computer and the second computer are not communicably connected. The first server 1 sends information which is used when the second server ii backs up (hereafter called catalog information) to the first storage system 21. The first storage system 21 converts the received catalog information into an electronic file having a predetermined file name and writes it to the PVOL 45, and writes the data group including the catalog information in the PVOL 45 to the SVOL 145 in the second storage system 121. The second server II acquires the catalog information from the SVOL 145 by searching the predetermined file name in the SVOL 145, and backs up the data in the SVOL 145 using the acquired catalog information.
