## Databunker
|
||||
|
||||
Databunker 是 CTP 中作为备份集中存储备选账户的内部命名账户。
|
||||
|
||||
### 用途
|
||||
|
||||
- 当 DRA 账户不可用时,作为集中账户存储备份副本
|
||||
- 作为跨区域、跨账户备份架构的降级方案
|
||||
- 配合 AWS Backup 的跨账户复制机制使用
|
||||
|
||||
### 架构关系
|
||||
|
||||
- [[DRA-Account]] 为每个生产工作负载的专属 DR 账户(主方案)
|
||||
- [[Databunker]] 为集中备份账户(降级方案)
|
||||
- 两个账户均使用 [[AWS-Backup]] 的 Vault Lock 确保不可变性
