Abstract

The invention provides a file recovery method and device, equipment and a storage medium. The method comprises the following steps: determining that the initialization of an embedded equipment systemfails at a boot initialization stage of the embedded equipment system; obtaining a basic file configuration table and a backup file configuration table from a file system; wherein the backup file configuration table is a backup of the basic file configuration table; If the basic file configuration table is different from the backup file configuration table, recovering the basic file configurationtable according to the backup file configuration table so as to perform initialization according to the recovered basic file configuration table. According to the method, the damaged file configuration table is automatically repaired by the embedded equipment in the system boot initialization stage, so that the operating system can be normally started, the service influence on the online equipmentis reduced, the maintenance efficiency is improved, and the maintenance cost is reduced.

Description

technical field [0001] The present application relates to the field of embedded technology, and in particular to a file recovery method, device, equipment and storage medium. Background technique [0002] With the continuous development of information technology, embedded technology has been applied to various fields. Before the embedded device runs, it needs to read and verify the system files to complete the initialization in the system boot stage, so as to bring the system environment to a suitable state and start the operating system to run. However, during the operation of embedded devices, system files in the file system are often destroyed due to abnormal operations (such as crashes, power failures, etc.) and system destructibility and instability. For example, the file configuration table in the embedded device file system is damaged or the file data area is wrong. The damage of these two system files will cause the embedded device to fail to initialize, making the ...
