HOT STORAGE BACKUP SYSTEM AND METHOD FOR SERVER

A hot storage backup system and method for server, relating to the technical field of servers. The method includes: after a Complex Programming Logic Device (CPLD) in a hard disk backboard detects access of a hard disk, triggering a hard disk access signal and sending same to a Central Processing Unit (CPU), and sending command parameters, corresponding to the hard disk, combined by a Basic Input Output System (BIOS) to the CPU; and checking, by the CPU, the command parameters with a mapping table, and in the case that the check is successful, setting an Advanced Configuration and Power Management Interface (ACPI) protocol according to the command parameters, so that the server normally recognizes the hard disk, thereby implementing a hot storage backup function through the hard disk.
