Abstract

A server data backup control method comprises a data management step, a checking step and a synchronous updating step. In the step of managing data, a first management unit of a main hard disk expansion card device distinguishes a plurality of main control system state data and a plurality of hard disk state data into a plurality of groups of information groups, and in a main checking step of the checking step, the first management unit executes a first checking instruction and only needs to check a state bit value of each information group, and whether all the main control system state data and the hard disk state data are updated or not is not needed to be checked, so that the data reading quantity is greatly reduced. In the step of synchronous updating, the first management unit only transmits all data in the information group with updating variation to a subordinate hard disk expansion card device and synchronously updates the data to the corresponding information group in the subordinate hard disk expansion card device, thereby effectively saving time and having good efficiency.

Description

Data backup control method for server Technical Field The present invention relates to a control method, and more particularly, to a server data backup control method. Background In computers or servers, it has been common to utilize clustered disk systems (e.g., just a Bunch Of Disks, JBOD) for system data storage management. Generally, a JBOD device is connected to a plurality of hard disks through an internal hard disk expansion control unit (expander), and detects information of the JBOD device and the plurality of hard disks and generates corresponding detection information (such as temperature or on/off state, etc.). When the JBOD device is connected with a host, the detection information is correspondingly acted according to the instruction sent by the host, for example, the detection information is returned to the host or the data of the plurality of hard disks are accessed, and the controller module of the hard disk expansion control unit can receive the data state information of the server and can monitor and store the operation state of the server system, such as CPLD state data information, cable on-line state data information, sensor state data information, LED state data information and other state data information of an interface physical layer (PHY) state data information of the hard disk. In the data storage technology, dual controller modules of a master controller and a slave controller capable of mutually backing up data are commonly utilized, except that the master controller can periodically update all data state information synchronization (Sync) of the master controller to the slave controller for backing up, the master controller can also periodically screen information from the slave controller, and after the master controller screens the slave controller for data, the master controller can integrate the data with the data of the master controller and then transmit the integrated data to the slave controller for synchronously updating all data state information, so that the data can be backed up and stored and protected, and the problem of data damage caused by abnormality of a single controller module is effectively avoided. However, the amount of data that the master controller updates all data state messages (Sync) to the slave controller each time is very large, and when only a small amount of data in the master controller needs to be updated to the slave controller synchronously, the master controller still updates all data state messages (Sync) to the slave controller, which is very time-consuming and inefficient. Moreover, the amount of data that the master controller screens the slave controller each time is very large, and even if the data status messages of the slave controller are unchanged, the master controller periodically screens the slave controller for messages, which is not efficient. And after the master controller screens the data from the slave controller, the data and the data of the master controller are integrated and then are transmitted to the slave controller to synchronously update all data state messages, so that the master controller and the slave controller need to communicate for many times regularly and the communication information amount is huge, which is very time consuming and the master controller and the slave controller often can screen and backup the data state messages which are not updated for many times in a meaningless way, thereby causing poor efficiency and further needing to be discussed and improved by practitioners. Disclosure of Invention The invention aims to provide a server data backup control method capable of reducing the read data quantity and having good efficiency. In order to solve the technical problems, the invention provides a server data backup control method which is applied to a server data backup control system, wherein the server data backup control system comprises a main control main board, a main hard disk expansion card device arranged on the main control main board, a slave hard disk expansion card device arranged on the slave main board and a storage device.
