Data protection method for managing increment file based on digital identifiers

Abstract

The invention relates to a data protection method for managing an increment file by using digital identifiers, and belongs to the technical field of data storage and backup. The method comprises the following steps of: numbering a catalogue and representing the catalogue by using the digital identifiers; numbering files under the catalogue and representing the files by using the digital identifiers; and synthesizing operating records into the increment file and representing the synthesized increment file by using the digital identifiers. An index is created for fields of the digital identifiers by using a database indexing technology. During recovery, all increment information of the file to be recovered can be quickly found, so that the file version at any modification time can be quickly recovered.

Description

technical field [0001] The invention belongs to the technical field of data storage and backup, in particular to a data protection method for managing incremental files with digital identifiers. Background technique [0002] With the continuous improvement of the level of informatization, data information has gradually become the basis for the survival of enterprises, and the losses caused by data loss are becoming more and more serious. Although traditional data protection technologies such as data replication, backup, and recovery can achieve a certain degree of data protection, the recovery point objective and recovery time objective of these methods are too long, which is unacceptable for some key information systems. Therefore, it is necessary to reduce the "fixed time interval" of data backup as much as possible, or even reduce it to zero. Continuous Data Protection (CDP, Continuous Data Protection) is a data protection technology that appears to meet such requirements...

Problems solved by technology

[0009] 1. When storing incremental files, the length of the original storage path will be increased, causing some files with long original paths to be unable to be backed up;

[0010] 2. It is not easy to encrypt, and the backup path and file name will also lead to the leakage of user information;

[0011] 3. Affect the portability of the backup storage body: For example, there are no restricted characters in the file name under linux, but there are restricted characters under windows. In this way, if the files backed up under linux are saved to the partition of windows, it is possible unable to store

[0012] Another method has nothing to do with the original path of the backed-up files, open up an area in the storage body, and store all the incremental files generated in a unified way. The problem brought about by this is that there are more and more incremental files, resulting in searching for incremental files. Slower and takes more time to restore files
