Common Tasks

After completing basic preparations such as accounts, permissions, databases, and networks, you can view common practices to better use DRS.

**Table 1** Common practices
Scenario		Practice	Description
Creating a Task	Real-Time Migration	From Other Cloud MySQL to RDS for MySQL	This practice describes how to use DRS to migrate data from a MySQL database on another cloud to a Huawei Cloud RDS for MySQL instance through a public network.
		From Other Cloud MySQL to GaussDB(for MySQL)	This practice describes how to use DRS to migrate data from a MySQL database on another cloud to a Huawei Cloud GaussDB(for MySQL) instance through a public network.
		From Other Cloud MongoDB to DDS	This practice describes how to use DRS to migrate data from a MongoDB database on another cloud to a Huawei Cloud DDS instance through a public network.
		From ECS-hosted MySQL to RDS for MySQL	This practice describes how to use DRS to migrate data from a MySQL database built on an ECS to an RDS for MySQL instance in the same VPC of the same region through a VPC.
		From ECS-hosted MySQL to GaussDB(for MySQL)	This practice describes how to use DRS to migrate data from a MySQL database built on an ECS to a GaussDB(for MySQL) instance in the same VPC of the same region through a VPC.
		From ECS-hosted MongoDB to DDS	This practice describes how to use DRS to migrate data from a MongoDB database built on an ECS to a DDS instance in the same VPC of the same region through a VPC.
		From On-Premises MySQL to RDS for MySQL	This practice describes how to use DRS to migrate data from an on-premises MySQL database to a Huawei Cloud RDS for MySQL instance through a public network.
		From On-Premises MongoDB to DDS	This practice describes how to use DRS to migrate data from an on-premises MongoDB database to a Huawei Cloud DDS instance through a public network.
		From RDS for MySQL to DDM	This practice describes how to use DRS to migrate data from a Huawei Cloud RDS for MySQL instance to a DDM instance in different regions through a VPN.
		From MySQL Schema and Logic Table to DDM	This practice describes how to use DRS to migrate data from MySQL shards and tables to a DDM instance through a public network.
	Backup Migration	Migrating Microsoft SQL Server Backup Data to RDS for SQL Server	This practice describes how to use DRS to restore local Microsoft SQL Server data backups to an RDS for SQL Server instance. DRS supports full backup migration and full+incremental backup migration.
	Real-Time Synchronization	From Other Cloud PostgreSQL to RDS for PostgreSQL	This practice describes how to use DRS to synchronize data from a PostgreSQL database on another cloud to an RDS for PostgreSQL instance through a public network.
		From ECS-hosted PostgreSQL to RDS for PostgreSQL	This practice describes how to use DRS to synchronize data from a PostgreSQL database built on an ECS to an RDS for PostgreSQL instance through a VPC.
		From On-Premises PostgreSQL to RDS for PostgreSQL	This practice describes how to use DRS to synchronize data from an on-premises PostgreSQL database to an RDS for PostgreSQL instance through a public network.
		From On-Premises Oracle to GaussDB	This practice describes how to use DRS to create a full+incremental task to continuously synchronize data from an on-premise Oracle database to a GaussDB instance through a public network.
		From On-Premises Oracle to DDM	This practice describes how to use DRS to create a full+incremental task to continuously synchronize data from an on-premise Oracle database to a DDM instance through a public network.
		From RDS for MySQL to Kafka	This practice describes how to use DRS to create an incremental task to synchronize incremental data from an RDS for MySQL instance to a Kafka instance through a VPC.
	Real-Time DR	Configuring Remote Single-Active DR for an RDS for MySQL Instance Using DRS	This practice describes how to use DRS to synchronize data from an RDS for MySQL instance in the production center to an RDS for MySQL instance in the DR center through a public network to implement data DR between the primary instance and the DR instance across regions.
Querying Task Progress	Real-Time Migration	Querying the Migration Progress	DRS shows the task progress using a progress bar, helping you keep track of the status of a task.
	Real-Time Synchronization	Querying the Synchronization Progress
	Real-Time DR	Querying the DR Progress
Comparing Data	Real-Time Migration	Comparing Migration Items	Data comparison allows you to check data consistency between source and destination databases before and after the migration. To minimize the impact on services and shorten the service interruption duration, DRS provides multiple comparison methods.
	Real-Time Synchronization	Comparing Synchronization Items
	Real-Time DR	Comparing DR Items
Managing Tasks	Real-Time Migration	Migration Task Life Cycle	During the life cycle of a DRS task, you can edit, pause, reset, resume and stop the task, and modify the flow control mode of the task as required.
	Real-Time Synchronization	Synchronization Task Life Cycle
	Real-Time DR	DR Task Life Cycle
