Creating an RDS Backup Migration Task

Supported Source and Destination Databases

Prerequisites

• You have logged in to the DRS console.
• Your account balance is greater than or equal to $0 USD.
• For details about the supported DB types and versions, see Supported Databases.
• If a subaccount is used to create a DRS task, ensure that an agency has been added. To create an agency, see Agency Management.

Before Backing Up File

Learn the backup migration constraints before starting a migration task.

Precautions

This section describes constraints on backup migrations of Microsoft SQL Server databases.

Procedure

This section describes how to create an RDS full backup migration task. You can use the full backups of Microsoft SQL Server DB instances in the cloud to migrate data.

1. On the Backup Migration Management page, click Create Migration Task.
2. On the Select Backup page, specify information about the task and backup files. Then, click Next.

   Table 4 Task information

   Parameter	Description
   Task Name	The task name consists of 4 to 50 characters, starts with a letter, and can contain only letters (case-insensitive), digits, hyphens (-), and underscores (_).
   Description	The description consists of a maximum of 256 characters and cannot contain special characters !=<>'&"\

   Table 5 Backup file information

   Parameter	Description
   Database Type	Select Microsoft SQL Server.
   Backup File Source	Select RDS full backup. NOTE: Select a backup file whose status is Completed.
   Enterprise Project	If the DB instance has been associated with an enterprise project, select the target project from the Enterprise Project drop-down list. You can also go to the ProjectMan console to create a project. For details about how to create a project, see the ProjectMan User Guide.
   Tags	Tags a task. This configuration is optional. Adding tags helps you better identify and manage your tasks. Each task can have up to 10 tags. After a task is created, you can view its tag details on the Tags tab. For details, see Tag Management.

3. On the Select Destination page, specify database information and click Next.

   Table 6 Database information

   Parameter	Description
   Destination RDS DB Instance Name	Select a destination RDS DB instance. If no RDS DB instance is available, you can create one.
   Backup Database Name	After you select the destination RDS DB instance, all databases to be restored are automatically displayed. You can select databases to be restored as required and rename them. Backup Database Name: Name of the database to be restored. New Database Name: The backup database name must consist of 1 to 64 characters. It can contain only uppercase letters, lowercase letters, digits, hyphens (-), and underscores (_). If the name is not specified, the original database name is used. NOTE: The backup database can be renamed. A maximum of 100 backup databases can be created. The new database name cannot be the same as the name of any other database in the source.

4. On the Confirm Task page, check configuration details, read and agree to the agreement, and click Next.
   

   If the SQL Server source contains non-clustered index tables, the index information of non-clustered index tables will become invalid after the SQL Server backups are restored to a new database. For the best performance, rebuild the indexes after the backup migration. In addition, the backup files store only database-level information. If the SQL Server source contains some instance-level configurations, such as login, permission, DBlink, and job, migrate these configurations by referring to Manual Configuration.

5. In the task list on the Backup Migration Management page, check whether the task is in the Restoring status. If the migration is successful, the task status becomes Successful.
