This topic describes how to use ApsaraDB RDS together with self-managed database instances to implement geo-disaster recovery.
Use of an ApsaraDB RDS instance together with a self-managed database instance
You can use Data Transmission Service (DTS) to synchronize data from a self-managed database instance that is deployed in an on-premises data center or on an Elastic Compute Service (ECS) instance to an ApsaraDB RDS instance that resides in any Alibaba Cloud region in real time. If the data of the self-managed database instance is lost due to unexpected exceptions such as data center damages, you can use the data backups stored in the ApsaraDB RDS instance to restore the data.
For more information, see Configure a data synchronization task.
Cross-region backup and restoration
ApsaraDB RDS for MySQL provides the cross-region backup feature. This feature allows an ApsaraDB RDS for MySQL instance to automatically synchronize the backup files stored in the RDS instance to an Object Storage Service (OSS) bucket that resides in a different region. You can use the cross-region backup files to manage and restore the RDS instance in the event of unexpected exceptions. For more information, see Enable cross-region backups for an ApsaraDB RDS for MySQL instance.
