22、演著越來越重要的角色。在通訊、金融、醫(yī)療、電子商務、物流、政府等領域,信息系統(tǒng)業(yè)務中斷會導致巨大經濟損失、影響品牌形象并可能導致重要數(shù)據(jù)丟失。因此,保證業(yè)務連續(xù)性是信息系統(tǒng)建設的關鍵。目前,各行業(yè)普遍通過建設災備中心來提高關鍵應用的業(yè)務連續(xù)性,在災備中心保存生產數(shù)據(jù)副本。傳統(tǒng)災備部署方式為一個生產中心對應一個災備中心,災備中心平時不對外提供業(yè)務訪問。一旦生產中心發(fā)生災難,業(yè)務癱瘓,無法短時間恢復時,災備中心才應需啟動以提供業(yè)務訪問。這種
