Problems solved by technology

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a method and system for improving deduplication performance and deduplication rate based on compression, which is used to solve the problems caused by the low deduplication ratio in the prior art. Space occupation, network bandwidth occupation, and data protection window time reduction effects are not obvious, so that the expected effect of deduplication cannot be achieved; low performance of deduplication will lead to longer data protection window time, so that data cannot be protected in time The problem

Abstract

The present invention provides a compression based deduplication performance and deduplication rate improving method. The method comprises the steps of: S1, acquiring to-be-transmitted data and data length after deduplication; S2, compressing the data after deduplication; S3, replacing the data and the data length after deduplication with the data and the data length after compression; S4, comparing the data length after deduplication with the data length after compression; and S5, adding a difference value after comparison into a numerical value for calculating a deduplication ratio. The compression based deduplication performance and deduplication rate improving method and system disclosed by the present invention can improve the deduplication ratio and performance of deduplication, thereby better reducing the occupied data storage space, network occupied network bandwidth and data protection window time.

Description

technical field [0001] The present invention relates to the field of deduplication data, in particular to a method and system for improving deduplication performance and deduplication rate based on compression. Background technique [0002] With the continuous development of computers, there are more and more effective data in computers. The accumulation of a large amount of data has brought great challenges to data protection. In order to solve this problem, many vendors have proposed solutions for data deduplication. [0003] Data deduplication can remove duplicate data by comparing existing data with fingerprints of existing data, thereby reducing storage space occupation, network bandwidth occupation, and data protection window time. Although the technologies used by various vendors to implement data deduplication are very similar, the effects achieved are quite different. Among them, the deduplication ratio and performance are the two key points to detect the pros and...
