数据异地容灾的实现

日益增长的信息量必然发生大量的数据传输、存储和数据交换，数据安全成为影响整个信息系统的一个重要因素为了应付区域性灾害，如地震、海啸、战争等因素导致多个机房同时损毁，数据永久性丢失，其它如区域性的病毒泛滥、蓄意破坏、严重误操作等人为因素也可能导致同城备份中心失效。建立一套异地数据备份系统已经成为信息系统建设的必要组成部分，会成为保证数据安全的最后一道防线。本文详细阐述了某信息系统数据异地容灾的实现。

The realization of data disaster recovery

More and more information is inevitable data transmission, storage and data exchange, data security has become an important factor affecting the entire information system in order to cope with the regional disaster, such as earthquake, tsunami war and other factors leading to multiple room also damaged, permanent loss of data, such as regional spreading of virus, sabotage, serious errors such as factors may also lead to local backup center failure. To establish a set of remote data backup system has become a necessary part of the construction of information system, will be the last line of defense to keep the data safe. This paper describes in detail the implementation of remote data disaster recovery system of certain information.
