Embodiment Construction

[0145] With the continuous advancement of storage technology, the amount of data generated is also increasing, and a large amount of data puts forward the highest requirements for storage capacity. The increase in storage capacity also increases the procurement cost of IT equipment. In order to alleviate the demand contradiction between data volume and storage capacity and save IT equipment procurement costs, data deduplication technology is introduced in the field of data storage.

[0146] A usage scenario in the embodiment of the present invention is a data backup scenario. Data backup is the process of backing up data to other storage media through the backup server to prevent data loss caused by various reasons. like figure 1 The data backup system architecture shown. The data backup system includes clients (101a, 101b...101n), backup server 102, data deduplication server (referred to as deduplication server or deduplication server) 103 and storage devices (104a, 104b......

Abstract

The embodiment of the invention provides a method for inquiring about a data flow break point on the basis of a server. In the method, by judging whether at least part of data in a certain window of M windows meets preset conditions or not, the data flow break point is inquired about; when at least part of data in a certain window does not meet the preset conditions, N*U lengths are skipped, and the next potential break point is obtained. The data flow break point inquiry efficiency is improved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a server-based method for searching data stream segmentation points and a server. Background technique [0002] The continuous growth of data volume makes providing sufficient data storage a serious challenge in the current storage field. One way to address this challenge is to take advantage of the redundant nature of the data that needs to be stored and use de-duplication technology to reduce the amount of stored data. [0003] In the prior art, the data deduplication algorithm based on Content Defined Chunk (CDC) first needs to divide the data stream to be stored into many data blocks, and to divide the data stream into data blocks needs to find the appropriate data stream in the data stream. The data between the split points of two adjacent data streams constitutes a data block. Calculate the characteristic value of the data block to find out whether there is a data bl...
