Description
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a disaster recovery backup method, apparatus, device, and machine-readable storage medium.
Background
In the server domain, management can be divided into in-band and out-of-band management. In-band management: and monitoring the machine through the main CPU. Generally, a piece of management software needs to be installed on the computer, so the management is called Agent management. The reason for the in-band management is performed by the main CPU, so that theoretically all information can be acquired, and the functions are complete. Managing outside the band: the machine is monitored without the main CPU, and the machine is monitored by the BMC. This method is called Agentless management because it does not require any software to be installed on the main CPU. Since many resources are not directly accessible, functionality is relatively weak with respect to in-band management.
The BMC (Baseboard Management Controller) implements out-of-band Management functions and can be a Controller for implementing Platform Management (Platform Management). Platform management represents a series of monitoring and control functions, and the object of operation is system hardware. Such as by monitoring the temperature, voltage, fan, power supply, etc. of the system and making adjustments to ensure that the system is in a healthy state. Meanwhile, the platform management is also responsible for recording information and log records of various hardware and is used for prompting a user and positioning subsequent problems. The BMC is an independent system, does not depend on other hardware (such as a CPU (Central processing Unit), a memory and the like) on the system, or on the BIOS, an OS and the like, but can interact with the BIOS and the OS, so that a better platform management effect can be achieved, and system management software under the OS can cooperate with the BMC to achieve a better management effect.
Since the BMC modules of each house are private, great inconvenience is brought to users, and if servers of different manufacturers exist in a machine room, different management software of each manufacturer must be installed for managing the servers, and the management modes and functions are different. In order to improve the situation, the Intel leads to the establishment of a set of IPMI protocol specifications. The set of specifications defines the behavior and the interface of the BMC, and the BMC conforming to the IPMI specification can be monitored by using a universal interface, so that the compatibility of the server is greatly improved.
Currently, a server based on the IPMI protocol can utilize a Baseboard Management Controller (BMC) to intelligently monitor, control and automatically report the operation status of a large number of servers, so as to reduce the system cost of the server.
For the purpose of low cost, a BMC module is usually configured on a server motherboard, so that the module manages the operating conditions of the server, such as the device temperature, the system operating status, and the like.
The BMC only plays a monitoring role of a server operation function at present, and performs log alarm if the temperature is too high or too low, but may cause interruption of some important services when a network administrator performs abnormal data processing.
