本课只做一件事：把「业务连续性与灾后恢复」的 6 个高频英文术语从「眼熟」变成「能用」：定义、易混、例句。

Turn the six high-frequency terms of Business Continuity & Recovery from familiar to usable: definition, look-alike, example.

本课不涉及：不扩到别的板块的术语，也不考题型技巧。
Not covered here: No terms from other blocks, no question-technique work.

本课目标 | Learning objectives

  1. 为每个术语说出定义，而不是只给中文对应词
  2. 指出每一对易混词差在哪一个限定条件上
  3. 把每个术语放进一句真实的现场英文里

  • Define each term rather than translate it
  • Point to the exact qualifier that separates each look-alike pair
  • Put each term into one real site sentence

    术语详解 | Glossary in depth

    BIA / 业务影响分析
    识别关键流程、量化停机后果的分析过程，是 BC 计划的输入。
    The analysis that identifies critical processes and quantifies downtime consequence; the input to any BC plan.
    易混 / Easily confused：易混：BIA 与风险评估。风险评估看「多可能出事」，BIA 看「出了事停多久会死」。
    Risk assessment asks how likely; BIA asks how much downtime kills you.
    例句 / In a sentence：No BIA, no priorities. / 没有 BIA 就没有优先级。
    RTO / 恢复时间目标
    流程必须恢复到可接受水平所允许的时间，必须小于 MTD。
    The time allowed to restore a process to an acceptable level; must sit inside the MTD.
    易混 / Easily confused：易混：RTO 与 MTD。MTD 是不能逾越的红线，RTO 是给自己定的目标。
    MTD is the cliff; RTO is your target.
    例句 / In a sentence：RTO 6 h inside MTD 8 h. / RTO 6 小时，MTD 8 小时。
    RPO / 恢复点目标
    可接受的数据丢失时间跨度，决定备份频率（RPO 1 小时 = 每小时备份）。
    The acceptable data-loss window, which sets backup frequency — an RPO of one hour means hourly backups.
    易混 / Easily confused：易混：RPO 讲「丢多少」，RTO 讲「停多久」。
    RPO is how much data, RTO is how long down.
    例句 / In a sentence：Backups follow RPO. / 备份频率跟着 RPO 走。
    MTD / 最大可容忍停机
    流程停摆造成不可接受后果（客户流失、违约、监管处罚）的时间阈值。
    The downtime threshold beyond which consequences become unacceptable — lost customers, breach, enforcement.
    易混 / Easily confused：易混：MTD 由业务方定，不是安全部门拍。
    The business owns the MTD, not EHS.
    例句 / In a sentence：MTD is a business number. / MTD 是业务数字。
    Critical Process / 关键流程
    停摆即导致停产、违法、伤人或不接受客户损失的流程。
    A process whose stoppage causes production loss, violation, injury or unacceptable customer loss.
    易混 / Easily confused：易混：关键流程与高价值流程。挣钱最多的不一定停不得。
    Most profitable is not the same as must-not-stop.
    例句 / In a sentence：Rank by consequence. / 按后果排序。
    Restart Permit / 复工许可
    灾后按结构/电气/气体/水患四项评估并签字后签发的书面复工授权。
    The written authorization issued after structure, electrical, gas and water assessments are signed off.
    易混 / Easily confused：易混：复工许可与动火票。前者管「能不能复产」，后者管「能不能点火」。
    One allows production, the other allows ignition.
    例句 / In a sentence：No signature, no power. / 不签字不上电。

    情景自测 | Scenario check

    术语辨析Terminology check

    这道题考什么：考 RPO 的实践含义。
    Tests what RPO means in practice.

    公司定 RPO 为 15 分钟，最直接的含义是？

    An RPO of fifteen minutes most directly means?

    自编练习题，不是 BCSP 官方真题，也不能用来预测分数。 / Original practice item, not an official BCSP exam question.

    动手练 | Practice

    1. 为你的一条产线写 RTO / RPO / MTD 三个数并说明依据。
    Write RTO, RPO and MTD for one line, with justification.
