Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the schematic embodiments and descriptions are only used to explain the present invention, but are not intended to limit the present invention.

[0023] See attached figure 1 , which shows the basic steps of a client file recovery method of the present invention:

[0024] Step 1: When no failure occurs, send a mirroring request to the management server, requesting file mirroring;

[0025] Step 2: According to the file segmentation strategy provided by the management server, perform file segmentation processing on the local files that need to be mirrored;

[0026] Step 3: Segment mirroring is performed to the set of repair terminals corresponding to each segment Lj in turn;

[0027] Step 4: When a failure occurs, restore the data of the failed client according to the data stored in the repair terminal;

[0028] See attached figure 2...

Abstract

The invention relates to a client file recovery method. The method includes: sending a mirroring request to a management server to request file mirroring when no failure occurs; performing file segmentation on the local files that need to be mirrored according to the file segmentation strategy provided by the management server. Segment processing; sequentially perform segment mirroring to the recovery end set corresponding to each segment Lj; when a failure occurs, perform data recovery on the faulty client according to the data stored in the recovery end. This method can automatically perform parallel repairs, consider the priority of the file itself, and provide different levels of repair services. By establishing a binding port and multiple repair files, the speed and security of file repair are improved, and the existing data repair is solved. The problem is simple and lacks security.

Description

【Technical field】 [0001] The invention belongs to the field of file restoration, in particular to a file restoration method of a client. 【Background technique】 [0002] When the storage medium is damaged or the data is invisible, unreadable, or lost due to misuse by personnel or failure of the operating system itself. Engineers use special means to read data that is invisible, unreadable, and unreadable under normal conditions. Data recovery (Data recovery) refers to the rescue of electronic data lost on desktop hard disks, notebook hard disks, server hard disks, storage tape segments, mobile hard disks, U disks, digital memory cards, Mp3, etc. through technical means. and recovery techniques. Data recovery is an industry with relatively high technical content. Data recovery technicians need skills in assembly language and software applications, as well as electronic and mechanical maintenance and hard disk technology. [0003] In the existing technology, files are saved ...
