Many colleges and universities have their own network system. And as the information release platform, the mail system, collaborative office, in-depth application of campus card services, information is getting more and more valuable into massive data, the value of data is more and more high, any data loss will bring great loss to the school. In order to ensure the teaching, scientific research, management and other related activities of normal operation, is very important to the corresponding information system disaster recovery construction. From the technology point of view, the establishment of a disaster recovery system is generally divided into based on host (including applications and database operation Diary) and based on storage (storage disk array of disk array) two kinds of schemes have their own advantages and disadvantages. Based on the analysis of various disaster recovery technology, puts forward a reasonable plan and prospects the future of the disaster backup. 【Keywords】disaster recovery data backup disaster recovery application level disaster recovery synchronous asynchronous 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc 前 言 PAGEREF _Toc \h 1 HYPERLINK \l _Toc 第一章 容灾备份系统相关说明 PAGEREF _Toc \h 2 HYPERLINK \l _Toc 1.1容灾、备份的区别与联系 PAGEREF _Toc \h 2 HYPERLINK \l _Toc 1.2窖灾备份系统的划分 PAGEREF _Toc \h 2 HYPERLINK \l _Toc 1.3同步和异步的选择 PAGEREF _Toc \h 4 HY
