Similar to Google Cloud Storage, **TiDB Dedicated supports dual-region pairing only within the same multi-region code as Google dual-region storage**. For example, in Asia, currently you must pair Tokyo and Osaka together for dual-region storage. For more information, refer to [Dual-regions](https://cloud.google.com/storage/docs/locations#location-dr).
 
 TiDB Dedicated supports dual region backup by replicating backups from your cluster region to another different region. After you enable this feature, all backups are automatically replicated to the specified region. This provides cross-region data protection and disaster recovery capabilities. It is estimated that approximately 99% of the data can be replicated to the secondary region within an hour.
