Restoring a DB Instance from a Backup

Scenarios

This section describes how to use an automated or manual backup to restore a DB instance to the status when the backup was created.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select a region and a project.
  3. Click Service List. Under Database, click Relational Database Service to go to the RDS console.
  4. On the Backup Management page, locate the target backup and click Restore in the Operation column.

    Alternatively, click the target DB instance on the Instance Management page. On the Backups & Restorations page, locate the target backup and click Restore in the Operation column.

  5. In the displayed dialog box, configure required information and click OK.

    1. Select a restoration method.
      • Create New Instance
        The Create New Instance page is displayed.
        • The DB engine and version of the new DB instance are the same as those of the original DB instance. The database port is 1433 by default.
        • Storage space of the new DB instance is the same as that of the original DB instance by default and must be greater than or equal to that of the original DB instance.
        • Other parameters use the default values and can be modified. For details, see section Creating a DB Instance.
        •  
      • Restore to Original

        Microsoft SQL Server currently does not support restoration to the original DB instance.

  6. View the restoration result. The result depends on which restoration method was selected:

    A new DB instance is created using the backup data. The status of the DB instance changes from Creating to Available.

    The new DB instance is independent from the original one.

    After the restoration, the system will perform a full backup.
