## DRA Account
|
||
|
||
DRA（Disaster Recovery Account）账户是 CTP（Cloud Transformation Programme）中为每个生产工作负载账户设立的专属灾备账户。
|
||
|
||
### 用途
|
||
|
||
- 存储从源账户复制过来的备份恢复点
|
||
- 实现物理隔离：工作负载账户被入侵时，备份不会一并丢失
|
||
- 支持即时恢复：备份保留在 DR 账户内，无需耗时跨账户数据拷贝即可完成恢复
|
||
|
||
### 架构关系
|
||
|
||
- 源账户 → 取初始备份 → 复制到 → **DRA Account**
|
||
- 如 DRA 账户不可用，备份可回退到 [[Databunker]] 集中账户
|
||
- DRA 账户配合 AWS Backup Audit Manager 提供合规审计报告
