## Source File
- [[raw/Cloud & DevOps/Public-Cloud-Learning-Sessions/01_AWS-Landing-Zone/ctp-topic-72-implementing-an-enterprise-dr-strategy-using-aws-backup.md]]

## Summary
- **核心主题**: 使用 AWS Backup 实现企业级灾难恢复策略
- **问题域**: DR 与 HA 的区别、RTO/RPO 定义、AWS Backup 架构
- **方法/机制**: AWS Backup 服务、全备份与增量备份、备份计划、Vault Lock、跨账户备份
- **结论/价值**: AWS Backup 是完全托管的策略驱动备份服务，支持多种资源类型，与 Organizations 集成实现跨账户备份副本

## Key Claims
- 高可用性（HA）关注系统运行时间和平均故障间隔，灾难恢复（DR）关注数据丢失防护
- RPO 定义可接受的数据丢失量，RTO 定义可接受的停机时间
- AWS Backup 是策略驱动的备份服务，支持与 Organizations 集成实现跨账户备份
- Vault Lock（合规模式）防止任何人（包括 root 用户）在生命周期结束前删除恢复点

## Key Quotes
> "We should always be prepared for a situation that everything falls all the time." — Sabith (AWS)

> "Human errors, technical failures, and natural disasters are major categories to consider when creating DR plans."

> "AWS Backup is a fully managed, policy-based backup service that simplifies data protection."

## Key Concepts
- [[灾难恢复]]: 系统故障后的数据还原流程
- [[高可用性]]: 通过冗余和故障转移确保系统持续可用的设计原则
- [[RPO]]: Recovery Point Objective，可接受的数据丢失量
- [[RTO]]: Recovery Time Objective，可接受的停机时间
- [[Shared Responsibility Model]]: AWS 与客户在云安全方面的责任划分

## Key Entities
- [[AWS]]: 全球最大公有云平台，提供 AWS Backup 服务
- [[AWS-Organizations]]: AWS 账户管理服务，用于跨账户备份
- [[IAM]]: AWS 身份与访问管理，用于备份访问控制
- [[AWS-Backup-Audit-Manager]]: AWS Backup 合规审计服务（BAM）
