Zusammenfassung:Embodiments of the present disclosure provide a hot backup system, a hot backup method, and a computer device. The hot backup system includes a centralized management module, a master server, a slave server and a delay server. The master server is configured to receive a write instruction sent by the centralized management module. The slave server is configured to perform data synchronization with the master server in real time, receive a read instruction sent by the centralized management module, and send second data read based on the read instruction to the centralized management module to cause the centralized management module to send the second data to the service server.
