If you enable the cross-region backup feature for an ApsaraDB RDS for MySQL, ApsaraDB RDS for SQL Server, or ApsaraDB RDS for PostgreSQL instance in the ApsaraDB RDS console, Database Backup (DBS) transfers and backs up the data of the instance across regions by using Express Connect. A backup schedule used to dump the data of the instance is generated in the DBS console. You can view the information about the source database on the details page of the backup schedule.
