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 for 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 Cross-region backup.
