Embodiment Construction

[0028] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0029] figure 1 is a flow chart of the first embodiment of the data processing method for backing up the database according to the present invention. Such as figure 1 As shown, the method includes the following steps:

[0030] Step S102, acquiring a backup file of the original file in the database, wherein the backup file includes multiple sub-files.

[0031]Backup files are files copied to storage media, which can help users protect data from being destroyed when system hardware or storage media fails. The common ways to realize backup are: use U disk or mobile hard disk to back up important data from the computer; Floppy disk backup data, etc. According to the backup content, it can be ...

Abstract

The invention discloses a data processing method and device for backing up a database. The data processing method for backing up the database includes: obtaining the backup file of the original file in the database, wherein the backup file contains multiple sub-files; obtaining header file information of the backup file, wherein the header file information contains the original storage addresses corresponding to the multiple sub-files ; Determine the feature information, wherein the feature information is the information contained in multiple sub-files to be moved in the multiple sub-files and the information that the non-to-be-moved sub-files do not contain; Read the multiple to-be-moved files that contain feature information from the header file information respectively The original storage address corresponding to the subfile; synchronously move multiple subfiles to be moved from the corresponding original storage address to the target storage address. Through the present invention, batch restoration of sub-files in backup files can be realized so as to improve the restoration efficiency of sub-files in backup files.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data processing method and device for backing up a database. Background technique [0002] Backup files are files copied to storage media, which can help users protect data from being destroyed when system hardware or storage media fails. A backup file often contains one or more file groups, and each file group can contain one or more sub-files. In a production environment, it is often necessary to restore one or more subfiles in a backup file to a specified disk path in order to efficiently utilize the characteristics of concurrent disk IO. In the prior art, the restoration of the sub-file in the backup file is usually realized through manual judgment, that is, the user reads the original storage address of the sub-file and restores the sub-file from the original storage address to the target storage address. This method can only restore one sub-file at a time, and cannot rest...
