Remote disaster recovery from a user-created database to an RDS instance
You can use DTS to synchronize the data of a database in any user-created data center or an ECS-hosted database in one region to an RDS instance in another region in real time. In such case, you can always retrieve a backup of your data on Alibaba Cloud even if your data center is damaged.
For more information about how to synchronize data, see Create a data synchronization task.
Cross-region backup and restoration
RDS MySQL can automatically replicate backup files from your computer to an OSS bucket that is located in a region different from your computer. The backup file replicates are used to manage and restore your RDS instance. For more information, see Restore the data of an RDS MySQL instance across regions.
