1. A data management method using multiple edge devices connected to the Internet,
a format of communication data on the Internet including data control information and communication data main body,
the data control information including control information,
the control information including a description of storage locations of distributed data,
a first edge device including a first edge agent, the first edge device for acquiring original data,
a first memory device including a device agent, a first data area, and a first management information area, the first memory device for recording the original data,
a second edge device connected to the first edge device via the Internet including a second edge agent and a second memory device, the second memory device including a second data area and a second management information area, and
a third edge device connected to the first edge device via the Internet including a third edge agent and a third memory device, the third memory device including a third data area and a third management information area,
the method comprising:
when determining a risk of overwriting recorded data in the first data area by the device agent, performing cooperation between the first edge agent and the device agent;
distributing the recorded data to the second data area of the second memory device and the third data area of the third memory device by the first edge agent; and
at a time of the distributing, conveying the recorded data by the communication data main body, conveying a description of a storage location of the recorded data in the communication data main body by the control information, storing the communication data main body in the second data area and the third data area, and storing the control information including a description of storage locations of the distributed data in the second management information area and the third management information area wherein
the first edge device inquires of the second edge device and the third edge device for the storage locations,
wherein, if one of the description of data storage locations stored in one of the second edge device or third edge device is lost, the first edge device can use another one of the description of data storage locations.
