摘　　要：在存储管理中,数据保护是重要的一环。本文提出了一种基于Linux平台远程逻辑卷复制系统的灾难恢复策略,并论述了它的基本原理及实现方法。该灾难恢复策略保证了本地系统的数据卷在遭受灾难的情况下,可以被远程系统进行接管,并在适当时候根据远程数据卷实现本地数据的有效恢复,大大提高了数据保护能力,并在一定程度上降低了管理开销。Protecting data from disaster is a key issue in storage management. This paper presents a kind of strategy of disaster recovery based on the remote logical volume replication system on Linux,and discusses its principle and implement method. The strategy guarantee that in the case of the local data volumes in disaster, they can be token over by the remote data volumes immediately, and be recovered from the latter in future, which improves the ability to protect data and makes it possible to control the overhead.
