Data synchronization method and system of redundant device, storage medium and electronic device

The invention discloses a data synchronization method and system of redundant equipment, a storage medium and electronic equipment. The data synchronization method comprises the following steps: a target device sends a data synchronization request to a data source device; starting a target device according to the first operation data from the data source device; controlling the target equipment and the data source equipment to operate synchronously according to the second operation data from the data source equipment; wherein the first operation data is generated by the data source equipment according to the data synchronization request, and the second operation data is obtained by periodically updating the first operation data by the data source equipment. The target device and the data source device can run synchronously through the first running data of the data source device and the periodically updated second running data. And the out-of-step equipment can be re-synchronized in time through the periodica
