## Source File
- [[raw/Cloud & DevOps/Public-Cloud-Learning-Sessions/10_OpenText-Series/public-cloud-learning-sessions-opentext-evolving-from-dr-to-recovery-assurance-2.md]]

## Summary
- 核心主题：灾难恢复（DR）向恢复保障（Recovery Assurance）的演进
- 问题域：企业级 DR 策略改进与 SRE 实践
- 方法/机制：通过设计、软件、构建、环境四个维度构建恢复保障能力
- 结论/价值：从被动响应式测试转向主动式恢复保障架构

## Key Claims
- DR 需要从被动响应转向Recovery Assurance的主动式架构
- RTO（恢复时间目标）和RPO（恢复点目标）是DR策略的核心指标
- 恢复保障应是设计原则，而非事后补救
- SRE和可观测性工程是提升恢复能力的关键技术

## Key Quotes
> "CrowdStrike was not us, but we have had some disruptions." — Jim Rose, 提及基础设施安全事件对DR策略的影响

> "Every person who is a SME on some part of this has to be involved in developing a plan." — Jim Rose, 描述DR测试的复杂性

## Key Concepts
- [[Recovery Assurance]]：恢复保障，从设计层面确保系统具备恢复能力
- [[SRE]]：站点可靠性工程，将软件工程方法应用于运维
- [[Observability Engineering]]：可观测性工程，通过持续监控理解系统健康状态

## Key Entities
- [[OpenText]]：企业解决方案公司，主办本次学习活动
- [[Jim Rose]]：演讲者，DR/Recovery Assurance专家
- [[CrowdStrike]]：安全公司，其安全事件推动了行业对DR的重视
