Embodiment Construction

[0012] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0013] A method for rebuilding the directory structure of disaster data files, comprising the following steps:

[0014] 101 Recover all the data in the disk by gradually scanning the key information FILE0, including normal data, lost data and deleted data; 102 analyze all the recovered data, classify the data by file type number, and divide it into folder data and file data ;Preserve the folder class data in the database table 1, and filter the directory information with the same content in the folder class data to ensure that there is no repeated identical directory information; save the file class data to the database table 2; 103 read the database All the data information in the file is analyzed and its affiliation is determined to reconstruct the di...

Abstract

The invention discloses a method for reconstructing a disaster data file directory structure and belongs to the field of data disaster recovery. The method includes the steps that 101, key information FILE0 is scanned step by step to restore all data in a disk, wherein the data includes normal data, obliterated data and deleted data; 102, all the restored data is analyzed, the data is classified through file type numbers and classified into fold data and file data; the fold data is saved in a database table 1, same-content directory information in the fold data is screened and filtered out, and it is guaranteed that no repeated or same directory information exists; the file data is saved in a database table 2; 103, all data information in a database is read and analyzed, relation of subordination of the data information is determined, and the disaster data file directory structure is reconstructed. By means of the method, file types can be fast differentiated, and the data file directory structure with the hierarchical relation can be fast built.

Description

technical field [0001] The invention relates to the field of data disaster recovery, in particular to a method for rebuilding the directory structure of disaster data files. Background technique [0002] Data disaster recovery refers to the recovery of lost data and reduction of disaster losses through the corresponding data recovery technology system when electronic data storage devices fail or encounter unexpected disasters that cause data to be lost unexpectedly. As an important part of the "disaster response mechanism", data disaster recovery plays an inestimable role in strengthening the disaster emergency system and reducing people's economic losses. It is also an indispensable basic security facility in the information society. [0003] Disaster data recovery often involves massive amounts of data, and when the data files and their directories are out of order and have no hierarchical relationship, it is difficult to organize the recovered data into a hierarchical rel...
