Disclosed are a system update method, apparatus, and device, which belong to the field of information technologies. The method comprises: determining a currently used system, and synchronizing a system file of the currently used system to a corresponding mirror system; acquiring a system update package, and updating, according to the system update package, the mirror system after synchronization; and after the mirror system after synchronization has been successfully updated, starting the updated mirror system, and using the updated mirror system as the currently used system. In the disclosure, system update is performed in a mirror system, after the mirror system has been successfully updated, the updated mirror system is started, and the updated mirror system is used as a currently used system, so that system update does not influence normal use of the currently used system, and a case in which the currently used system cannot be normally used because of an exception that occurs in a process of system update is also prevented, thereby enhancing system safety and stability. |
