A Duplicate-Aware Data Replication
Jianfeng Zhu, Qin Leihua, Zeng Dong, Zhou Jinli · 2008
In this paper, we employ the data de-duplication technology to detect the duplicate data in the process of data replication. By avoiding duplicate data, data replication reduces the quantity of data transmission, and save the replication I/O bandwidth. In additional, the data consistency has been guaranteed in the same time. The work is a part of our project which is to build a wide-area disaster recovery system.
