A backup method and device

Abstract

The invention relates to the technical field of computer communication, in particular to a backup method and a backup device, aiming to reduce redundant data in a communication device and reduce production cost of the communication device. The method comprises the following steps of identifying whether service integrated circuit boards are inserted into both slots respectively corresponding to a main slot identification and a paired secondary slot identification according to the paired main slot identification and secondary slot identification stored in configuration information, wherein the main slot identification is used for uniquely identifying the slot a main service integrated circuit board to insert, and the secondary slot identification is used for uniquely identifying the slot allowing a spare service integrated circuit board to insert; if so, pointing the data finger of the spare service integrated circuit board inserted in the slot corresponding to the secondary slot identification to the storage position of the data content of the main service integrated circuit board inserted in the slot corresponding to the paired main slot identification. Thus, with the adoption of the method, the redundant data in the communication device can be reduced, and the production cost of the communication device can be reduced.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a backup method and equipment. Background technique [0002] At present, in communication equipment, in order to avoid interruption or error of communication equipment due to hardware failure and ensure long-term stable operation of communication services, it is usually used to add redundant physical equipment to all working equipment in communication equipment to realize data backup. . When the equipment in the working state fails, it will quickly switch to the standby equipment corresponding to the working equipment, so that the standby equipment can continue to complete the relevant operations of the working equipment, so as to ensure that the ongoing business can be restored at the telecommunication level. [0003] But the inventor finds that there are following two defects in the prior art: [0004] First. It is necessary to add a redundant physical device t...

Problems solved by technology

[0004] First. It is necessary to add a redundant physical device to each working device, and back up the redundant physical device with the same data content as the working device, so a lot of redundant data is generated;

[0005] Second, when the user does not need to use a certain work equipment, the user also has to purchase the redundant physical equipment corresponding to the work equipment while purchasing the communication equipment. Therefore, while increasing the production cost of the communication equipment, It also increases the user's purchase cost
