1、--本科畢業(yè)論文(20__屆)嘉興市電信公司災(zāi)備技術(shù)應(yīng)用分析摘要在當(dāng)前信息時(shí)代,通常數(shù)據(jù)資源比計(jì)算機(jī)設(shè)備本身的價(jià)值要高得多。近年來(lái)隨著網(wǎng)絡(luò)技術(shù)的飛速發(fā)展,形成了數(shù)據(jù)在網(wǎng)絡(luò)環(huán)境中的高度集中存儲(chǔ),在簡(jiǎn)化數(shù)據(jù)管理,提高運(yùn)行效率,降低投資成本的同時(shí),也使數(shù)據(jù)的安全性經(jīng)受著更為嚴(yán)峻的考驗(yàn)。面對(duì)系統(tǒng)數(shù)據(jù)安全要求和應(yīng)用需求同時(shí)要得到滿足的情況,如何做到容災(zāi)與應(yīng)用兩不誤,如何在可以容忍的時(shí)間內(nèi)恢復(fù)業(yè)務(wù)支撐系統(tǒng)的正常運(yùn)行,如何將企業(yè)因業(yè)務(wù)中斷而導(dǎo)致的損失降低到預(yù)定的程度是一個(gè)值得研究的問(wèn)題。本文通過(guò)實(shí)地調(diào)研的形式,主要調(diào)研了嘉興市電信公司在災(zāi)難備份技術(shù)方面的情況(主要包括
2、現(xiàn)有的幾種數(shù)據(jù)恢復(fù)的方式和方法),初步了解了目前嘉興市電信公司現(xiàn)有的災(zāi)難備份應(yīng)急方案,根據(jù)應(yīng)急方案設(shè)計(jì)了災(zāi)難備份的演練方案。通過(guò)本演練方案實(shí)施,對(duì)災(zāi)難恢復(fù)預(yù)案中的組織機(jī)構(gòu)、相關(guān)人員、災(zāi)難恢復(fù)的有關(guān)過(guò)程及操作,組織的協(xié)調(diào)能力、災(zāi)難備份系統(tǒng)恢復(fù)和災(zāi)難恢復(fù)計(jì)劃進(jìn)行一次全面的檢查和驗(yàn)證,提高災(zāi)難發(fā)生時(shí)數(shù)據(jù)恢復(fù)的效率。關(guān)鍵詞:電信運(yùn)營(yíng)商;災(zāi)難備份;演練方案17AbstractIntheinformationage,usuallythevalueofdataresourcesismuchhigherthencomputerequipment.Inrecentyear
