Embodiment Construction

[0027] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0028] The embodiment of the present invention provides a method for server to compress data, such as figure 1 As shown, the method includes:

[0029] S101. The server parses the information block in the data block, and acquires the file type of the data block and the sub-data blocks included in the data block.

[0030] It is worth noting that the information block of the data block can be the block header (Block Header) of the data block, which is used to describe the attributes of the data in the data block, and the attributes of the data include the file type of the data stored in the data block and The location of the different regions in the data block. Specifically, a specific byte is included in the information block to indicate the file type of the data stored in the data block, and the data b...

Abstract

A server and a method for compressing data by the server relate to the storage field, and are used to solve the problem in the prior art that the compression rate of data in a server compressed data block is low. The method includes: the server parses the information block in the data block, Obtaining the file type of the data in the data block and the sub-data blocks included in the data block; determining the characteristics of the data in the sub-data blocks according to the file type; A target compression algorithm for the data in the data block; compressing the data in the sub-data block using the target compression algorithm. Embodiments of the present invention are used to compress data.

Description

technical field [0001] The invention relates to the field of storage, in particular to a server and a method for compressing data by the server. Background technique [0002] At present, in order to save storage space, existing servers generally support the compression of stored data. [0003] In the prior art, the server uses a preset compression algorithm to compress the data in the sub-data block. For example, the server uses a dictionary compression algorithm. In this case, the server scans the data in the data block byte by byte to obtain Identify consecutively repeated character strings in a data block, and compress the consecutively repeated character strings. [0004] It can be known from the above that the server can only use one compression algorithm to compress the data of a specific characteristic in the data block. Therefore, the compression rate of the data in the data block is relatively low in the prior art. Contents of the invention [0005] The object o...
