摘要：PURPOSE:To accelerate a back-up operation when a fault arises, by connecting an auxiliary computer in parallel to a primary computer and storing all data transferred to the primary computer also in the auxiliary computer. CONSTITUTION:The data transferred between a refrigerator 5 and a host computer 1 via a front machine 2 are all applied to a front machine 2' through a line 15 and stored in a storage device 12'. The machine 2' monitors the signal emerging at the line 15, and the machine 2' is actuated when the machine 2 has a fault. Then the data stored in the device 12' are transferred to the computer 1 by an instruction given from the computer 1. At the same time, the data given from the terminal refrigerator 5 is read by the machine 2'.
