Abstract: Embodiments of the present disclosure provide a hot standby method, apparatus, and system. The method includes: saving, by an active device, first user information of the active device into a local cache module of the active device and sending, by the active device, the first user information to a remote cache module of a first standby device based on preset correlation information. In response to detecting that the active device becomes faulty, the first standby device obtains the first user information from the remote cache module of the first standby device and restores the first user information.
