Restoring a DB Instance to a Specified Time

The Amazon RDS automated backup feature automatically creates a storage volume snapshot of your DB instance, backing up the entire DB instance and not just individual databases. This backup occurs during a daily user-configurable 30 minute period known as the backup window. Automated backups are kept for a configurable number of days (called the backup retention period). You can restore your DB instance to any specific time during this retention period, creating a new DB instance.

When you restore a DB instance to a point in time, the default DB security group is applied to the new DB instance. If you need custom DB security groups applied to your DB instance, you must apply them explicitly using the AWS Management Console, the Amazon RDS API ModifyDBInstance action, or the AWS CLI modify-db-instance command once the DB instance is available.

You can restore to any point in time during your backup retention period. To determine the latest restorable time for a DB instance, use the AWS CLI describe-db-instances command and look at the value returned in the LatestRestorableTime field for the DB instance. The latest restorable time for a DB instance is typically within 5 minutes of the current time.

The OFFLINE, EMERGENCY, and SINGLE_USER modes are not currently supported. Setting any database into one of these modes will cause the latest restorable time to stop moving ahead for the whole instance.

Several of the database engines used by Amazon RDS have special considerations when restoring from a point in time. When you restore an Oracle DB instance to a point in time, you can specify a different Oracle DB engine, license model, and DBName (SID) to be used by the new DB instance. When you restore a SQL Server DB instance to a point in time, each database within that instance is restored to a point in time within 1 second of each other database within the instance. Transactions that span multiple databases within the instance may be restored inconsistently.

Some actions, such as changing the recovery model of a SQL Server database, can break the sequence of logs that are use for point-in-time recovery. In some cases, Amazon RDS can detect this issue and the latest restorable time is prevented from moving forward; in other cases, such as when a SQL Server database uses the BULK_LOGGED recovery model, the break in log sequence is not detected. It may not be possible to restore a SQL Server DB instance to a point in time if there is a break in the log sequence. For these reasons, Amazon RDS does not support changing the recovery model of SQL Server databases.

AWS Management Console

To restore a DB instance to a specified time

  1. Sign in to the AWS Management Console and open the Amazon RDS console at https://console.aws.amazon.com/rds/.

  2. In the navigation pane, click DB Instances.

  3. Click Instance Actions, and then click Restore To Point In Time.

    The Restore DB Instance window appears.

  4. Click on the Use Custom Restore Time radio button.

  5. Enter the date and time that you wish to restore to in the Use Custom Restore Time text boxes.

  6. Type the name of the restored DB instance in the DB Instance Identifier text box.

  7. Click the Launch DB Instance button.

CLI

To restore a DB instance to a specified time, use the AWS CLI command restore-db-instance-to-point-in-time to create a new database instance.

For Linux, OS X, or Unix:

Copy
aws rds restore-db-instance-to-point-in-time \ --source-db-instance-identifier mysourcedbinstance \ --target-db-instance-identifier mytargetdbinstance \ --restore-time 2009-10-14T23:45:00.000Z

For Windows:

Copy
aws rds restore-db-instance-to-point-in-time ^ --source-db-instance-identifier mysourcedbinstance ^ --target-db-instance-identifier mytargetdbinstance ^ --restore-time 2009-10-14T23:45:00.000Z

API

To restore a DB instance to a specified time, call the Amazon RDS API RestoreDBInstanceToPointInTime function with the following parameters:

  • SourceDBInstanceIdentifier = mysourcedbinstance

  • TargetDBInstanceIdentifier = mytargetdbinstance

  • RestoreTime = 2013-10-14T23:45:00.000Z
