Embodiment Construction

[0027] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] as attached figure 1 As shown, a method for data reduction and deduplication and mirror remote backup protection, the implementation process is as follows:

[0029] 1. First, divide the data file to be stored into several data blocks;

[0030] 2. Then check the duplicated data blocks and delete the duplicated data blocks;

[0031] 3. Back up the processed data to a data storage pool, and then back up the storage pool to another ...

Abstract

The invention discloses a data simplified duplicate removal and mirror image remote backup protection method and system. The method comprises the steps of firstly segmenting to-be-stored data files into multiple data blocks; secondly performing duplicate checking on the segmented data blocks to delete duplicated data blocks; and thirdly backing up the processed data in a data storage pool, and backing up the storage pool in another mirror image storage pool. Compared with the prior art, the data simplified duplicate removal and mirror image remote backup protection method and system has the advantages that unique data is effectively protected after duplicated data in a production server is deleted; the method and the system are suitable for backup in medium and small-sized enterprises; thestorage space occupied for duplicated data transmission can be effectively reduced; the storage cost is reduced; the practicality is high; the application range is wide; and the popularization is easy.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a highly practical method and system for streamlining and deduplication of data and backup and protection of images in different places. Background technique [0002] Data backup storage not only involves complete, safe and stable data backup, but also stores data on corresponding media with high efficiency. Enterprises need to consider other important factors when choosing data backup storage. There are many backup plans. [0003] However, in the prior art, the data backup device is always filled with a large amount of redundant data, which leads to the need to occupy a large amount of bandwidth during the backup, and the backup space takes up a large amount. In order to solve this problem and save more space, "simplification and deduplication" came into being. However, in the prior art, the process of streamlining and deduplication is cumbersome, and the greater risk aft...
