Communication activities are one of the most basic activities in social activities. Today, communication activities have evolved into an era of interconnecting people, objects, and things through various communication devices. The important carrier for realizing the powerful functions is network communication equipment deployed on each layer, and the network communication equipment realizes the great revolution and qualitative leap of human communication activities by orderly and unified cooperation of division of labor.
The communication devices distributed at each node need to be configured correspondingly according to different application environments during deployment so as to adapt to the current network environment and complete the communication functions carried by the communication devices. These startup configuration data are roughly classified into: the method comprises two categories of equipment management function configuration and equipment service function configuration. Any kind of data is essential key information for normal operation of equipment and ensuring network smoothness. In the aspect of the use of the starting configuration data, the starting configuration data is mostly required to be immediately effective after being set, and communication equipment of a plurality of important nodes is required to be permanently effective after being set once. For communication equipment, reliable storage and accurate acquisition of these startup data are very important. In data storage, network devices are generally stored in a storage medium carried by the network devices, and when the network devices are started, the network devices are configured by reading the starting data on the storage medium.
The main technology of the backup synchronization method for starting configuration data at the present stage is as follows: a backup synchronization method for main and standby areas based on a nonvolatile storage medium. The method comprises the steps of opening up two areas with the same size on a nonvolatile storage medium, storing the same configuration data, acquiring the configuration data from the other area when the configuration data of one area is detected to be invalid, synchronizing the data of an effective area to the invalid area, and updating the main area and the standby area synchronously when the configuration data is changed. The method is simple, convenient and feasible and is a commonly applied method at present. However, this method stores backup data and main data in the same storage medium, and in case of damage to the storage medium, it may cause disastrous consequences to the start-up and stable operation of the device. Meanwhile, data is stored on a nonvolatile medium, and due to the low natural I/O efficiency of the equipment, the change and update perception of the configuration data during the operation are not facilitated to be realized efficiently.

Has the advantages that:
compared with the prior art, the method for starting the backup synchronization of the configuration data of the different nonvolatile storage media based on the memory cache provided by the invention displays and increases the data validity field stored on the nonvolatile storage media, can effectively judge the validity of the data, ensures the validity of the configuration data of the equipment, and prevents the communication equipment from being failed due to misconfiguration after the data is invalid.
