Problems solved by technology

Because the most intuitive problem brought by the rapid growth of data volume to the disaster recovery system is the lack of storage space, it also puts a huge pressure on the system's processing capacity and data transmission bandwidth. Therefore, in order to ensure the efficient and stable operation of the disaster recovery system, A storage capacity optimization mechanism needs to be established to reduce the data's demand for storage capacity

Embodiment Construction

[0016] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0017] refer to figure 2 As shown, a repetitive data processing technology includes two methods: static file segmentation and dynamic file segmentation, the static file segmentation is to segment the file according to a fixed size, and the dynamic file segmentation Splitting files includes the following steps:

[0018] Step 1) Find the boundary position of the data block according to a certain algorithm;

[0019] Step 2) Solve the data fingerprint, that is, after cutting the file into multiple small modules, it is necessary to calculate the data fingerprint for each small data block;

[0020] Step 3) Use data fingerprints to determine whether two data blocks are the same; when searching for data blocks, due to the large number of data blocks, using the function-based HASH search method can effectively shorten the search time;

Abstract

The invention discloses repeating data processing technology which includes two methods including static file segmenting and dynamic file segmenting. Static file segmenting refers to segmenting files according to a fixed size, and dynamic file segmenting includes the following steps: looking up border positions of data blocks according to a certain algorithm; solving data fingerprints; using the data fingerprints to judge whether two data blocks are same or not; storing the same data blocks into one portion, and storing index values of the same data blocks for the convenience of being used during recovery. By adopting the technical scheme, needs of data on storage capacity can be reduced; on the basis of in-depth study on storage capacity optimization technology in disaster recovery backup, a certain technological improvement on repeating data deleting technology is made, and high-quality storage is realized.

Description

technical field [0001] The invention relates to an alarm system, in particular to a repeated data processing technology. Background technique [0002] Today's enterprise's demand for information storage is growing rapidly, and the collection and processing of information has become one of the key technical factors that determine the survival and development of enterprises. At the same time, more and more attention has been paid to the reliability and security of data in information systems, and the data disaster recovery system is an effective technical means to ensure data security. Especially the 911 terrorist attack and the Southeast Asian tsunami, as well as the recent snowstorm and Wenchuan earthquake in southern China, these catastrophic events have made enterprises have a common thread, which is to establish a remote disaster recovery system to ensure business continuity. The disaster recovery system is proposed according to the current technological development tren...
