【摘要】 网络数据信息高可用性和高安全性的要求刺激了远程容灾备份技术的发展,由于传统的基于FC协议的远程容灾备份技术存在一些缺陷,目前出现了一种将远程镜像技术、IP的SAN互联技术和快照技术融合起来的远程容灾备份技术,该种容灾备份技术可避免基于FC协议的远程容灾备份技术的不足,具有较好的应用前景。文章对其关键技术进行了剖析,以便用户有一个较全面的了解。更多还原

【Abstract】 The high availability and security require for network data stimulates the development of disaster recovery with remote data backup. The traditional FC-based disaster recovery with remote data backup exists some drawbacks,at present, there is a new disaster recovery with remote data backup, it combines remote mirroring with IP-based SAN interconnection and snapshot. In order to make network users know the remote mirroring,IP- based SAN interconnection and snapshot, this paper introduces and analyses them.更多还原
