摘要
许多企业为了加强管理而建设了大集中布署的信息系统,这些信息系统面临着无法承受区域性灾难的风险。为了有效防范灾难事件,保障企业核心数据安全,就需要建设数据级灾难恢复系统。而根据不同的系统构架和运行环境,而其建设方法则有多种技术路线。对数据级灾难恢复系统所涉及到的各种数据复制技术进行了研究,对其优缺点进行了分析,希望在设计和实施中起到帮助作用。
Many enterprises to build a large centralized deployment of information systems, these information systems can not afford to face the risk of a regional disaster, in order to effectively prevent disasters, to protect the core data , they need to build data-level disaster recovery. While depending on the system architecture and operating environment, and its construction methods there are a variety of technical routes. In this paper, data-level disaster recovery involved in a variety of data replication techniques to study its strengths and weaknesses were analyzed, hoping in the design and implementation of help here.
