（O管理）对O数据库进行容灾(VVR(VVR))对Oracle数据库进行容灾（VeritasV olumeReplicator(VVR)）随着全球信息化时代的到来，信息数据越来越成为企业关注的焦点，即在各种自然灾害或者人为破坏的情况下，如何保证生产数据的安全和关键业务的不中断运行。

传统的保护方法离线备份、备份介质异地保存在一定程度上可以解决上述问题，但为了能够对业务系统提供更高的实时性和可靠性，保证关键业务7x24不中断，应对激烈的市场竞争和提高客户满意度，企业必须在IT系统围绕“连续”(BC)主题进行构建，实施业务连续/容灾备份计划，包括业务连续性、高可用性管理、容灾、数据复制和恢复方案、安全等，下面就对数据复制技术做一个简单的介绍。

根据数据复制运行的位置，可以将数据复制方式分为以下四种：基于存储(Storage-Based)：代表厂商有EMCSRDF、IBMPPRC/GDPS、HPBusinessCopy、HDSTrueCopy等，特点对主机透明，对应用系统的影响较小，技术成熟，有较多的成功案例，但是投资较大，对网络连接的要求也较高。

基于服务器(Host-based)：代表厂商主要是Symantec公司的VeritasVolumeReplicator(V VR)，是存储卷的复制技术。

需要占用主机一定的系统资源。

基于存储交换机(SAN-Based)：运行于挂接在存储网络上的专用设备中，代表厂商有CISCO 的SANTap，FalconStorIPStor，TopioSANsafe，DataCoreSANsymphony,Asynchrono usInternetMirroring(AIM)等。

基于数据库/软件应用:代表厂商有OracleDataGuard，QuestSharePlex，IBM-DB2的远程Q复制，SYBASE的复制服务器(ReplicationServer)等，这些技术都是对数据逻辑操作的复制，属于逻辑数据复制，而其它3种复制的是数据卷中的数据变化，属于物理数据复制。

RAID DP有两块校验盘，可以保护RAID组里面两块盘损坏，最少的盘数量至少是3块，一块数据盘,一块校验盘，一块dual校验盘。

如果是校验盘损坏了，则可以根据数据盘的内容来重建。
