## Summary

### 核心主题
AWS Backup 在云转型计划（CTP）中的实施，标准化备份流程。

### 问题域
- 生产工作负载的备份策略
- 跨账户跨区域备份设计
- SRE 模型的备份自动化

### 方法/机制
- AWS Backup 作为统一备份工具
- SRE 模型：允许产品组创建和控制备份
- 初始备份 + 复制到 DR 账户
- AWS Backup Audit Manager 审计与合规报告

### 结论/价值
- 备份策略灵活性和标准化兼顾
- 支持点时间恢复（PITR）
- 开箱即用的审计框架
- DR 账户存储备份，实现即时恢复

## Key Claims

- 生产工作负载备份策略要求：每24小时至少备份一次，保留至少30天，两个备份位置
- AWS Backup 设计：源账户初始备份 → 复制到 DR 账户/区域，支持无 DR 账户时使用 Databunker 作为集中备份账户
- SRE 备份模型简化 AWS Backup 采用：备份计划、选择、金库、KMS 策略、生命周期策略、审计报告等自动化
- AWS Backup Audit Manager 提供合规控制评估：备份计划保护、最小频率和保留、防止删除恢复点、加密恢复点、跨区域跨账户备份
