DATA SYNCHRONIZATION METHOD AND APPARATUS FOR REDUNDANT FIRMWARE, AND NON-VOLATILE READABLE STORAGE MEDIUM

Provided are a data synchronization method and apparatus for a redundant firmware (FW), and a non-volatile readable storage medium, applicable to the technical field of computers. In the method, a shared area is established, and a modifiable partition corresponding to the redundant FW is added to the shared area, so that the FW can access any modifiable partition of the shared area, and a fixed mapping relationship between the FW and the modifiable partition is removed, thereby solving the problem in the prior art that when a current FW is switched to another FW partition, data in a modifiable partition corresponding to an original FW is not synchronized into a modifiable partition of the current FW and consequently the data is lost. Modifiable partitions in the shared area are redundant modifiable partitions; if an abnormality occurs in the current FW, the current FW is switched to a FW to be synchronized, and data consistency is achieved by accessing the modifiable partition of the shared area, thereby achi
