摘要
源端数据重删技术应用期间,所遇到的问题比较多,比如计算指纹耗时长、重删效率低、数据库耗时等。设计数据备份恢复系统,在客户端分段数据流,通过预处理方式存储,并发执行整个处理过程。通过此种方式,可以缩短计算时间,提升缓存命中率。
During the application of source-side Data re-delete technology,there are many problems,such as time-consuming of computing fingerprint,low efficiency of re-delete,time-consuming of database,etc..A data backup and recovery system is designed,in which the data flow is segmented at the client,stored by pre-processing,and the whole process is executed concurrently.In this way,the computation time can be reduced and the cache hit ratio can be improved.
