### 使用限制

- 要使用此功能，TiDB Operator 应为 v1.4.0 及以上，TiDB 应为 v6.3.0 及以上。
- TiDB 集群部署在 EKS 上，且使用了 AWS EBS 卷。
- 仅支持在 AWS 上使用 EKS 和 TiDB Operator v1.4.0 及以上版本来部署和管理 TiDB 集群，并且要使用 EBS 卷来存储数据。
- 使用 TiDB v6.3.0 及以上版本。
- 仅支持将数据库恢复到备份时间点，暂不支持按照指定时间点进行恢复。
- 仅支持整个集群同拓扑恢复，暂不支持按照单库 / 单表恢复。
- 暂不支持 TiFlash、TiCDC、DM 和 TiDB Binlog 相关节点的卷快照备份。


> **注意：**
>
> - 集群从低于 v6.5.0 版本升级到 v6.5.0 时，可能无法进行卷快照备份。详细解决办法见[升级后备份无法工作](backup-restore-faq.md#升级后备份无法工作)。
