一种基于压缩的重复数据删除性能及重删率提升的方法和系统
摘要：
本发明提供一种基于压缩的重复数据删除性能及重删率提升的方法，包括步骤：S1、获取即将发送的重复数据删除后的数据及长度；S2、对所述重复数据删除后的数据进行压缩；S3、将压缩后的数据及其长度替换所述重复数据删除后的数据及其长度；S4、将所述重复数据删除后的数据长度和所述压缩后的数据长度进行对比；S5、将对比后的差值加入计算重删比的数值中。能够提升重复数据删除的重删比及性能，从而更好的缩减数据存储空间占用、网络带宽占用、数据保护窗口时间。
摘要（英）：

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.
