22、演著越來越重要的角色。在通訊、金融、醫(yī)療、電子商務(wù)、物流、政府等領(lǐng)域，信息系統(tǒng)業(yè)務(wù)中斷會(huì)導(dǎo)致巨大經(jīng)濟(jì)損失、影響品牌形象并可能導(dǎo)致重要數(shù)據(jù)丟失。因此，保證業(yè)務(wù)連續(xù)性是信息系統(tǒng)建設(shè)的關(guān)鍵。目前，各行業(yè)普遍通過建設(shè)災(zāi)備中心來提高關(guān)鍵應(yīng)用的業(yè)務(wù)連續(xù)性，在災(zāi)備中心保存生產(chǎn)數(shù)據(jù)副本。傳統(tǒng)災(zāi)備部署方式為一個(gè)生產(chǎn)中心對(duì)應(yīng)一個(gè)災(zāi)備中心，災(zāi)備中心平時(shí)不對(duì)外提供業(yè)務(wù)訪問。一旦生產(chǎn)中心發(fā)生災(zāi)難，業(yè)務(wù)癱瘓，無法短時(shí)間恢復(fù)時(shí)，災(zāi)備中心才應(yīng)需啟動(dòng)以提供業(yè)務(wù)訪問。這種
