摘要：According to the present invention, a file recovery system is provided in which
the commands for recovering files such as a historical file are unnecessitated and therecovery system configuration is independent of the host processing system. That is,since the equipment for achieving a file recovery does not have information about thelocation of the recovery data, information about the content of a file to be recovered istransmitted to a transmission line. The other equipments asynchronously receive theinformation and judges whether or not a file containing the same content exists in theown system. If its file exists, the content of the file is transmitted to the transmission line.The equipment achieving the file recovery asynchronously receives from the transmissionline the file data of files such as a historical file and establishes data consistency by use ofthe buffered current data and the event number, thereby recovering files such as ahistorical file.
