Specifically, if the main Qin system of the server 2 can be started, the BIOS 21 receives the Qin system from the main system of the server ..... . . . The boot information; if the main system of the server 2 is not bootable, the BIOS 21 collects system boot information from the backup initial system 30 of the server 2. In step S5, the BIOS 21 boots up to the main system of the server 2 or the initial system of the backup based on the collected system boot information. Specifically, if the host system of the server 2 can be booted, the BIOS 21 directly starts the host system; if the host system of the server 2 is not bootable, the BIOS 21 starts the initial system 30 of the backup of the server 2. 099140880 Form No. A0101 Page 9 / Total 20 Page 0992071133-0 201222238 [0034] [0036] Step S6 'The system check sub-module 2〇3 determines the main system of the server 2 or the backup Whether the initial system is a bare system. If the server 2 or the initial system of the backup is not a bare system, then step S7 is performed. • If the primary system of the server 2 or the initial system of the backup is a bare system, step S8 is performed. It can be understood that the primary system of the server 2 is not a bare system' and the initial system backed up by the server 2 is a bare system. In step S7, the server 2 executes the system task and controls the execution of the various applications. Step S8' The data recovery sub-modem 2〇2 obtains the main system backed up by the server 2 from the second storage 25 of the backup circuit 22, and transmits the backup main system to the body circuit 20 of the server 2, and then The server 2 is restarted, and the process returns to step S1. In this embodiment, the data backup sub-module 2〇1 backups the primary system of the secondary server 2, such as the first backup primary system 41 and the second backup master, every other preset time (for example, 5 minutes).
