摘要 重复数据删除技术包括相同数据重复数据删除技术和相似数据重复数据删除技术。相同数据重复数据删除技术主要有:相同文件重复数据删除技术、固定长度分块的重复数据删除技术、基于内容分块的重复数据删除技术、基于滑动块的重复数据删除技术和基于数据特征的重复数据消除算法等。重复数据删除技术适合应用于数据备份系统、归档存储系统、远程灾备系统等场合。 Data de-duplication technology can be used to de-duplicate instances of the same data or similar data. Same data de-duplication includes de-duplication of fixed-length blocks, Content Defined Chunking (CDC), sliding blocks, and characteristic-based elimination of duplicate data algorithm. This technology is especially applicable in data backup systems, archival storage systems, and remote disaster recovery systems.
