You can use Data Transmission Service (DTS) to synchronize data between data sources in real time. Typical scenarios include active geo-redundancy, geo-disaster recovery, zone-disaster recovery, cross-border data synchronization, cloud business intelligence (BI) systems, and real-time data warehousing. This topic describes the database types, synchronization types, and synchronization topologies that are supported by DTS.
In some scenarios, data synchronization can implement part of data migration features and can provide better network stability and additional features. For more information about the differences between the two features, see the "What are the differences between data migration and data synchronization?" section of the FAQ topic.
When you create a task to synchronize data to or from a database instance that is created in ApsaraDB MyBase, you can set the Access Method parameter to Alibaba Cloud Instance. This way, DTS can access the database instance. You can configure the synchronization task by referring to the topics listed in the following tables. For example, you can synchronize data from a self-managed MySQL database to an ApsaraDB MyBase for MySQL instance by referring to Synchronize data from a self-managed MySQL database to an ApsaraDB RDS for MySQL instance.
Synchronization types
Synchronization type | Description |
Schema synchronization | DTS synchronizes the schemas of the required objects from the source database to the destination database. Tables, views, triggers, and stored procedures can be synchronized. Important Before you configure a data synchronization task, check whether schema synchronization is supported. If schema synchronization is not supported, you must create a destination database and tables based on the schemas of required objects in the source database. |
Full data synchronization | DTS synchronizes the historical data of required objects from the source database to the destination database. Historical data is the basis for subsequent incremental synchronization. To simplify data synchronization, we recommend that you select both Schema Synchronization and Full Data Synchronization when you configure a data synchronization task. |
Incremental data synchronization | By default, incremental data synchronization is supported. DTS synchronizes incremental data that are generated in the source database to the destination database in real time. |
Synchronization topologies
For information about synchronization topologies, see Synchronization topologies.
Data synchronization scenarios
DTS supports the following data synchronization scenarios. You can select one of the following scenarios based on your business requirements to view the supported database versions, synchronization types, and configuration procedure.
Synchronize data from a self-managed MySQL database or an ApsaraDB RDS for MySQL instance
Synchronize data from a PolarDB for PostgreSQL(Compatible with Oracle) cluster
Synchronize data from a self-managed PostgreSQL database or an ApsaraDB RDS for PostgreSQL instance
Synchronize data from a self-managed SQL Server database or an ApsaraDB RDS for SQL Server instance
Synchronize data from a self-managed MongoDB database or an ApsaraDB for MongoDB instance
Self-managed databases mentioned in the following tables, such as a self-managed MySQL or Redis database, can be one of the following types:
Self-managed database hosted on an Elastic Compute Service (ECS) instance
Self-managed database connected over Express Connect, VPN Gateway, or Smart Access Gateway
Self-managed database without a public IP address or port number (connected over Database Gateway)
Self-managed database connected over Cloud Enterprise Network (CEN)
Synchronize data from a self-managed MySQL database or an ApsaraDB RDS for MySQL instance
A database in a PolarDB-X 1.0 instance must be created based on one or more ApsaraDB RDS for MySQL instances. DTS does not support PolarDB-X 1.0 databases that are created based on PolarDB for MySQL clusters.
For a data synchronization task that has a PolarDB-X 1.0 instance configured as the destination instance, schema synchronization and initial schema synchronization are not supported. Schema synchronization and initial schema synchronization are supported for PolarDB-X 2.0 instances.
A database in a PolarDB-X 2.0 instance must be compatible with MySQL 5.7. We recommend that you update the instance to version 5.4.11 or later. For more information about how to update the version of an instance, see View and update the version of an instance.

Synchronize data from a self-managed Redis database, a Tair instance, or an ApsaraDB for Redis instance
A Redis database is a NoSQL database that does not require schema synchronization.
A Tair enhanced SSD (ESSD)-based instance cannot be configured as the source database.
A two-way data synchronization task supports only ApsaraDB for Redis Enhanced Edition (Tair) instances that use local disks, Tair dynamic random access memory (DRAM)-based instances that use cloud disks, and Tair persistent memory-optimized instances that use cloud disks.
If the source database is a self-managed Redis database or an ApsaraDB for Redis Community Edition instance, full data synchronization and incremental data synchronization are supported and displayed as incremental data synchronization.
