本课只做一件事：搞清「业务连续性与灾后恢复」到底是什么、为什么考试要先过这一关、它管到哪里为止。

Get clear on what Business Continuity & Recovery really is, why it comes first, and where it stops.

本课不涉及：不展开细节与题目——那是第 2–5 课的事。
Not covered here: No detail, no questions — those are lessons 2 to 5.

本课目标 | Learning objectives

  1. 能用一句话说清「业务连续性与灾后恢复」解决的是什么问题
  2. 能举出一个「不懂它就一定做错」的例子
  3. 知道本课的边界，不把后续课的内容提前混进来

  • State in one sentence the problem Business Continuity & Recovery solves
  • Give one example where missing it guarantees a wrong answer
  • Know this lesson's boundary and keep later lessons out

    它是什么 | What it is

    业务连续性（BC）回答的是「坏了以后怎么活下来」，与应急响应（先把人救出来、把事按住）分工不同：应急响应管前 24 小时，BC 管之后的数周到数月。核心工具是业务影响分析 BIA——只问两件事：哪些流程必须活着、停多久就不可接受。后者量化为 MTD（最大可容忍停机），再由它倒推 RTO（恢复时间目标，必须 ≤ MTD）与 RPO（恢复点目标，即能容忍丢多少数据）。恢复优先级固定为：人 → 关键流程 → 厂房设施 → 系统与数据，资产永远排在人后面。灾后复工不靠「看着没事」，而靠结构、电气、气体、水患四项逐项评估、书面放行（Restart Permit）才可上电投产。恢复期本身是事故高发期：疲劳加班、临时接线、拆除动火、霉菌与污水暴露、发电机一氧化碳，都要在恢复方案里预设控制。

    Business continuity answers how the business survives after the event, while emergency response handles the first hours. The core tool is the business impact analysis, which asks only two questions: which processes must live, and how much downtime is intolerable. That becomes the MTD, and from it you derive the RTO (which must not exceed the MTD) and the RPO for data loss. Recovery priority is fixed: people, critical processes, facilities, then systems — assets never outrank people. Restart is not a judgement call but a written clearance covering structure, electrical, gas and water damage before energizing. Recovery itself is a high-incident period: fatigue, temporary wiring, demolition hot work, mould and sewage exposure, and generator carbon monoxide all need pre-planned controls.

    为什么先学它 / Why first
    三个坑：①把 BC 当应急预案——预案管救人控事，BC 管活下去；②RTO 拍脑袋定得比 MTD 还长——等于计划一启动就已经违约；③灾后「试一下能不能开」——水浸设备未烘干就上电，二次事故比原灾更贵。
    Three traps: treating BC as the emergency plan; setting an RTO longer than the MTD, so the plan fails the moment it starts; and powering up water-damaged equipment to see if it works — the second incident costs more than the first.
    它管到哪里为止 / Where it stops
    本块不展开 ISO 22301 认证条款、供应链金融与保险精算，只取 CSP 考试相关的 BIA、RTO/RPO/MTD 与复工放行逻辑。
    ISO 22301 clauses, supply-chain finance and actuarial detail are out of scope; the block stays with BIA, RTO/RPO/MTD and restart clearance.

    先认个脸 | Terms you will meet

    1. BIA — 业务影响分析
    2. RTO — 恢复时间目标
    3. RPO — 恢复点目标
    4. MTD — 最大可容忍停机
    5. Critical Process — 关键流程
    6. Restart Permit — 复工许可

    这里只要求认得；定义、易混与例句在本块第 3 课「术语精讲」。/ Recognition only — definitions come in the glossary lesson of this block.

    情景自测 | Scenario check

    本课理解Lesson comprehension

    这道题考什么：考 BC 的起点。
    Tests the starting point of BC.

    公司第一次做业务连续性计划，第一步应当是？

    A company writes its first business continuity plan. First step?

    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. 列你公司的五项关键流程，各写一个 RTO。
    List five critical processes with an RTO each.
