Supported Databases

DRS supports data flows between different DB engines. This section lists the supported databases in real-time migration, backup migration, real-time synchronization, data subscription, and real-time DR.

Real-Time Migration

You can migrate all database objects across cloud platforms, from on-premises databases to the cloud, or across regions on the cloud in real time. The following table lists the supported databases, versions, and migration types. For more information about real-time migration, see Real-Time Migration.

Self-managed databases (such as MySQL and MongoDB) refer to on-premises databases and databases created on an ECS. RDS for MySQL refers to the MySQL databases on Huawei Cloud RDS instances.

  • Some functions are only available for whitelisted users. To use these functions, submit a service ticket. In the upper right corner of the management console, choose Service Tickets > Create Service Ticket.
  • Data cannot be migrated from a newer version database to an older version database.

Backup Migration

You can export data from the source database to a backup file, upload the backup file to OBS, and then restore the backup file to the destination database. In this way, data migration can be complete without exposing your source database to the Internet. Table 8 lists the supported databases, versions, and migration types. For more information about backup migration, see Backup Migration.

Data cannot be migrated from a newer version database to an older version database.

Real-Time Synchronization

Real-time synchronization refers to the process of copying data from one data source to another database while keeping data consistency. In this way, the data of key services can flow in real time. The following table lists the supported databases, versions, and synchronization types. For more information about real-time synchronization, see Real-Time Synchronization.

Self-managed databases (such as MySQL, Oracle, and PostgreSQL) refer to on-premises databases and databases created on an ECS. RDS for MySQL refers to the MySQL databases on Huawei Cloud RDS instances.

  • Some functions are only available for whitelisted users. To use these functions, submit a service ticket. In the upper right corner of the management console, choose Service Tickets > Create Service Ticket.

Data Subscription

Data subscription is used to obtain data changes of key services in the database. DRS caches the data changes and provides a unified SDK interface for downstream services to subscribe to, obtain, and consume the changes. Table 22 describes the supported databases and data types. For details about data subscription, see Data Subscription.

Real-Time Disaster Recovery

To prevent service unavailability caused by regional faults, DRS provides disaster recovery to ensure service continuity. The floowing table lists the databases and versions supported by real-time DR. For more information about real-time DR, see Real-Time Disaster Recovery.

Self-managed databases (for example, MySQL) refer to on-premises databases and the databases created on an ECS. RDS for MySQL refers to the MySQL databases on Huawei Cloud RDS instances.

  • Some functions are only available for whitelisted users. To use these functions, submit a service ticket. In the upper right corner of the management console, choose Service Tickets > Create Service Ticket.
  • Disaster recovery cannot be performed from a later version database to an earlier version database.

Traffic Replay

A traffic replay task simulates the service load of the source database on the destination database so you can evaluate the effectiveness and performance of the destination database. Table 25 lists the supported databases and versions. For more information about traffic replay, see Traffic Replay.

Self-managed databases (such as MySQL and MariaDB) refer to on-premises databases and databases created on an ECS. RDS for MySQL refers to the MySQL databases on Huawei Cloud RDS instances.

  • Traffic cannot be replayed from a later version database to an earlier version database.
