Embodiment Construction

[0067] 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 in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0068] In a general large-scale information system, it usually contains dozens or even hundreds of servers, and each server is configured with important system files, application files or parameter configuration files. These files, but in some actual application environments, test Personnel, developers, managers, maintenance personnel, and other related personnel can access and use the same file in a certain server. After one of the above-mentioned roles accidentally deletes or modifies the file, the file will not be restored or even Unavailable, resulting in system crashes and application dama...

Abstract

The embodiment of the invention provides a file anti-deletion and modification method and device, and the method comprises the steps: obtaining a feature value of a target file; Obtaining a characteristic value of the backup file; Under the condition that the characteristic value of the target file is different from the characteristic value of the backup file, determining whether the difference between the target file and the backup file is allowed to be deleted or not; Under the condition that the difference between the target file and the backup file is allowed to be deleted, replacing the backup file with the target file; And under the condition that the difference between the target file and the backup file is not allowed to be deleted, replacing the target file with the backup file. In the embodiment of the invention, by determining the difference between the characteristic value of the target file and the characteristic value of the backup file, the mutual replacement of the target file and the backup file is realized, and the technical problem that in the prior art, the file cannot be recovered after the file is deleted and changed, so that the file is unavailable is solved.

Description

technical field [0001] The invention relates to the technical field of data control, in particular to a method and device for preventing file deletion and modification. Background technique [0002] In a large-scale information system, there are usually dozens or even hundreds of servers, and a large number of files are stored on each server, including system files, application files or configuration files. A certain file, in the actual environment, multiple roles such as developers, testers, maintainers, and managers can use the above file together. The file is deleted and modified, resulting in the situation that the file cannot be recovered or even used. [0003] Based on this, in the prior art, the content of the file itself is generally compared to determine whether the file has been deleted or altered. However, the collection content requires the read permission of the file. In practical applications, there are often situations where the file content needs to be kept...
