Restoring a DB Instance to a Point in Time

Scenarios

This section describes how to use existing automated backups to restore DB instances to a point in time.

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 Instance Management page, click the target DB instance.
  5. On the Backups & Restorations page, click Restore to Point In Time.
  6. In the displayed dialog box, configure required information and click OK.

    1. Select the time range, select or enter a time point within the acceptable range.
    2. 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.

  7. 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.
