Abstract

The invention provides a file recovery system and method. The system comprises a write-in module, a detection module, a recovery module and a restart module. The write-in module is used for writing target data into a primary zone and a backup zone which are opened in a memory cell; the detection module is used for detecting whether or not the target data in the primary zone is abnormal according to preset parameters; if the target data is abnormal, then the detection module sends a recovery instruction to the recovery module, or else, the detection module continues detecting abnormity of the target data; the recovery module is used for calling data in the backup zone for updating the target data and sending a restart instruction to the restart module after update; the restart module is used for restarting a terminal according to the restart instruction. According to the system and method of the invention, data is simultaneously written in the primary zone and the backup zone, the data in the primary zone can be checked in real time; once abnormal data is generated, the primary zone is updated from the backup zone at the same time, which guarantees the data integrity of the primary zone.

Description

technical field

[0001] The invention mainly relates to the technical field of system file processing, in particular to a file recovery system and method. Background technique

[0002] The file system is a system used to create files, save them, read them, modify them, etc. When the system is abnormal, it is easy to cause data loss, so abnormal data operation will bring serious consequences; currently, the solution to the above The solution to the problem is generally to set the operation node, check and update according to the operation node, and often cannot update in time when abnormal data has been generated. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a file recovery system and method. When writing data, write the main area and the backup area at the same time, and can check the data in the main area in real time. Once abnormal data is generated, it will be synchronized from the backup area. Updating to ...
