The invention concerns a system for saving data derived from a mainframe characterized in that it comprises a computer equipment including an input/output interface for exchanging data with the guest computer, said interface comprising a backup document reader/inscriber emulator, at least one intermediate storage device and a tape document reader/inscriber, the equipment further comprising a processor for transfer between the input/output interface or the intermediate storage device and the key-to-tape reader/inscriber, the system further including a supervisor comprising a storage unit for recording data concerning key-to-tape recordings of the computer equipment, and for controlling said computer equipment according to instructions coming from the guest computer.
A method for saving data originating from a host computer composed of a computer equipment including an input-output interface for exchanging data with the host computer, the said interface comprising a backup reader-inscriber emulator, at least one intermediate storage device and a tape reader-inscriber, the equipment also comprising a processor for making transfers between the input-output interface or the intermediate storage device interface and the tape reader-inscriber, wherein the system also comprises a supervisor comprising a memory for saving information about records on the computer equipment tape, and to control the said computer equipment as a function of instructions originating from the host computer, and a memory for making use of a database containing identification labels of the backed up data.
A method for saving data from a host computer wherein the input-output interface of a backup equipment is emulated so that the behaviour of the backup equipment is identical to the behaviour of a streamer, as far as the host machine is concerned, the said backup equipment comprising an intermediate storage means that is not the same as the streamer.
