# Restoring a DB cluster to a specified time
You can restore a DB cluster to a specific point in time, creating a new DB cluster.
When you restore a DB cluster to a point in time, you can choose the default virtual private cloud (VPC) security group. Or you can apply a custom VPC security group to your DB cluster.
Restored DB clusters are automatically associated with the default DB cluster and DB parameter groups. However, you can apply custom parameter groups by specifying them during a restore.
Amazon Aurora uploads log records for DB clusters to Amazon S3 continuously. To see the latest restorable time for a DB cluster, use the Amazon CLI [describe-db-clusters](https://docs.amazonaws.cn/cli/latest/reference/rds/describe-db-clusters.html) command and look at the value returned in the `LatestRestorableTime` field for the DB cluster.
You can restore to any point in time within your backup retention period. To see the earliest restorable time for a DB cluster, use the Amazon CLI [describe-db-clusters](https://docs.amazonaws.cn/cli/latest/reference/rds/describe-db-clusters.html) command and look at the value returned in the `EarliestRestorableTime` field for the DB cluster.
The backup retention period of the restored DB cluster is the same as that of the source DB cluster.
**Note**
Information in this topic applies to Amazon Aurora. For information on restoring an Amazon RDS DB instance, see [Restoring a DB instance to a specified time](https://docs.amazonaws.cn/AmazonRDS/latest/UserGuide/USER_PIT.html).
For more information about backing up and restoring an Aurora DB cluster, see [Overview of backing up and restoring an Aurora DB cluster](Aurora.Managing.Backups.md).
You can also use Amazon Backup to manage backups of Amazon Aurora DB clusters. If your DB cluster is associated with a backup plan in Amazon Backup, that backup plan is used for point-in-time recovery. For information, see [Restoring a DB cluster to a specified time using Amazon Backup](aurora-pitr-bkp.md).
For information about restoring an Aurora DB cluster or a global cluster with an RDS Extended Support version, see [Restoring an Aurora DB cluster or a global cluster with Amazon RDS Extended Support](extended-support-restoring-db-instance.md).

## Restoring a DB cluster to a point in time
You can restore a DB cluster to a point in time using the Amazon Web Services Management Console, the Amazon CLI, or the RDS API.
### Console
**To restore a DB cluster to a specified time**
1. Sign in to the Amazon Web Services Management Console and open the Amazon RDS console at [https://console.amazonaws.cn/rds/](https://console.amazonaws.cn/rds/).
1. In the navigation pane, choose **Automated backups**.
The automated backups are displayed on the **Current Region** tab.
![\[Automated backups configuration panel showing retention period settings and backup window options.\]](http://docs.amazonaws.cn/en_us/AmazonRDS/latest/AuroraUserGuide/images/db-cluster-automated-backups.png)
1. Choose the DB cluster that you want to restore.
1. For **Actions**, choose **Restore to point in time**.
The **Restore to point in time** window appears.
1. Choose **Latest restorable time** to restore to the latest possible time, or choose **Custom** to choose a time.
If you chose **Custom**, enter the date and time to which you want to restore the cluster.
**Note**
Times are shown in your local time zone, which is indicated by an offset from Coordinated Universal Time (UTC). For example, UTC-5 is Eastern Standard Time/Central Daylight Time.
1. For **DB cluster identifier**, enter the name of the target restored DB cluster. The name must be unique.
1. Choose other options as needed, such as the DB instance class and DB cluster storage configuration.
For information about each setting, see [Settings for Aurora DB clusters](Aurora.CreateInstance.md#Aurora.CreateInstance.Settings).
1. Choose **Restore to point in time**.
### Amazon CLI
To restore a DB cluster to a specified time, use the Amazon CLI command [restore-db-cluster-to-point-in-time](https://docs.amazonaws.cn/cli/latest/reference/rds/restore-db-cluster-to-point-in-time.html) to create a new DB cluster.
You can specify other settings. For information about each setting, see [Settings for Aurora DB clusters](Aurora.CreateInstance.md#Aurora.CreateInstance.Settings).
If tags are provided in the request then the provided tags are applied to the restored DB cluster. If tags are not provided in the request and if the source DB cluster is in-region active and has tags, Aurora adds the latest tags from the source DB cluster to the restored DB cluster.
**Example**
For Linux, macOS, or Unix:
```
1. aws rds restore-db-cluster-to-point-in-time \
2. --source-db-cluster-identifier mysourcedbcluster \
3. --db-cluster-identifier mytargetdbcluster \
4. --restore-to-time 2017-10-14T23:45:00.000Z
```
For Windows:
```
1. aws rds restore-db-cluster-to-point-in-time ^
2. --source-db-cluster-identifier mysourcedbcluster ^
3. --db-cluster-identifier mytargetdbcluster ^
4. --restore-to-time 2017-10-14T23:45:00.000Z
```
**Important**
If you use the console to restore a DB cluster to a specified time, then Amazon RDS automatically creates the primary instance (writer) for your DB cluster. If you use the Amazon CLI to restore a DB cluster to a specified time, you must explicitly create the primary instance for your DB cluster. The primary instance is the first instance that is created in a DB cluster.
To create the primary instance for your DB cluster, call the [create-db-instance](https://docs.amazonaws.cn/cli/latest/reference/rds/create-db-instance.html) Amazon CLI command. Include the name of the DB cluster as the `--db-cluster-identifier` option value.
### RDS API
To restore a DB cluster to a specified time, call the Amazon RDS API [https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_RestoreDBClusterToPointInTime.html](https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_RestoreDBClusterToPointInTime.html) operation with the following parameters:
+ `SourceDBClusterIdentifier`
+ `DBClusterIdentifier`
+ `RestoreToTime`

# Restoring a DB cluster to a specified time from a retained automated backup
You can restore a DB cluster from a retained automated backup after you delete the source DB cluster, if the backup is within the retention period of the source cluster. The process is similar to restoring a DB cluster from an automated backup.
## Console
**To restore a DB cluster to a specified time**
1. Sign in to the Amazon Web Services Management Console and open the Amazon RDS console at [https://console.amazonaws.cn/rds/](https://console.amazonaws.cn/rds/).
1. In the navigation pane, choose **Automated backups**.
1. Choose the **Retained** tab.

You can specify other settings. For information about each setting, see [Settings for Aurora DB clusters](Aurora.CreateInstance.md#Aurora.CreateInstance.Settings).
Resource tagging is supported for this operation. When you use the `--tags` option, the source DB cluster tags are ignored and the provided ones are used. Otherwise, the latest tags from the source cluster are used.
**Example**
For Linux, macOS, or Unix:
```
1. aws rds restore-db-cluster-to-point-in-time \
2. --source-db-cluster-resource-id cluster-123ABCEXAMPLE \

# Restoring a DB cluster to a specified time using Amazon Backup
You can use Amazon Backup to manage your automated backups, and then to restore them to a specified time. To do this, you create a backup plan in Amazon Backup and assign your DB cluster as a resource. Then you enable continuous backups for PITR in the backup rule. For more information on backup plans and backup rules, see the [https://docs.amazonaws.cn/aws-backup/latest/devguide](https://docs.amazonaws.cn/aws-backup/latest/devguide).
## Enabling continuous backups in Amazon Backup
You enable continuous backups in backup rules.
**To enable continuous backups for PITR**
1. Sign in to the Amazon Web Services Management Console, and open the Amazon Backup console at [https://console.amazonaws.cn/backup](https://console.amazonaws.cn/backup).
1. In the navigation pane, choose **Backup plans**.
1. Under **Backup plan name**, select the backup plan that you use to back up your DB cluster.
1. Under the **Backup rules** section, choose **Add backup rule**.
The **Add backup rule** page displays.
1. Select the **Enable continuous backups for point-in-time recovery (PITR)** check box.
![\[Enable continuous backups for point-in-time recovery (PITR).\]](http://docs.amazonaws.cn/en_us/AmazonRDS/latest/AuroraUserGuide/images/add_backup_rule_continuous_v2.png)
1. Choose other settings as needed, then choose **Add backup rule**.
## Restoring from a continuous backup in Amazon Backup
You restore to a specified time from a backup vault.
### Console
You can use the Amazon Web Services Management Console to restore a DB cluster to a specified time.
**To restore from a continuous backup in Amazon Backup**
1. Sign in to the Amazon Web Services Management Console, and open the Amazon Backup console at [https://console.amazonaws.cn/backup](https://console.amazonaws.cn/backup).
1. In the navigation pane, choose **Backup vaults**.
1. Choose the backup vault that contains your continuous backup, for example **Default**.
The backup vault detail page displays.
1. Under **Recovery points**, select the recovery point for the automated backup.
It has a backup type of **Continuous** and a name with `continuous:cluster-AWS-Backup-job-number`.
1. For **Actions**, choose **Restore**.
The **Restore backup** page displays.
![\[Restore backup page for point-in-time recovery (PITR).\]](http://docs.amazonaws.cn/en_us/AmazonRDS/latest/AuroraUserGuide/images/backup_vault_pitr.png)
1. For **Restore to point in time**, select **Specify date and time** to restore to a specific point in time.
1. Choose other settings as needed for restoring the DB cluster, then choose **Restore backup**.
The **Jobs** page displays, showing the **Restore jobs** pane. A message at the top of the page provides information about the restore job.
After the DB cluster is restored, you must add the primary (writer) DB instance to it. To create the primary instance for your DB cluster, call the [create-db-instance](https://docs.amazonaws.cn/cli/latest/reference/rds/create-db-instance.html) Amazon CLI command. Include the name of the DB cluster as the `--db-cluster-identifier` parameter value.
### CLI
You use the [start-restore-job](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/backup/start-restore-job.html) Amazon CLI command to restore the DB cluster to a specified time. The following parameters are required:
+ `--recovery-point-arn` – The Amazon Resource Name (ARN) for the recovery point from which to restore.
+ `--resource-type` – Use `Aurora`.
+ `--iam-role-arn` – The ARN for the IAM role that you use for Amazon Backup operations.
+ `--metadata` – The metadata that you use to restore the DB cluster. The following parameters are required:
+ `DBClusterIdentifier`
+ `Engine`
+ `RestoreToTime` or `UseLatestRestorableTime`
The following example shows how to restore a DB cluster to a specified time.
```
aws backup start-restore-job \
--recovery-point-arn arn:aws:backup:eu-central-1:123456789012:recovery-point:continuous:cluster-itsreallyjustanexample1234567890-487278c2 \
--resource-type Aurora \
--iam-role-arn arn:aws:iam::123456789012:role/service-role/AWSBackupDefaultServiceRole \
--metadata '{"DBClusterIdentifier":"backup-pitr-test","Engine":"aurora-mysql","RestoreToTime":"2023-09-01T17:00:00.000Z"}'
```
The following example shows how to restore a DB cluster to the latest restorable time.
```
aws backup start-restore-job \
--recovery-point-arn arn:aws:backup:eu-central-1:123456789012:recovery-point:continuous:cluster-itsreallyjustanexample1234567890-487278c2 \
--resource-type Aurora \
--iam-role-arn arn:aws:iam::123456789012:role/service-role/AWSBackupDefaultServiceRole \
--metadata '{"DBClusterIdentifier":"backup-pitr-latest","Engine":"aurora-mysql","UseLatestRestorableTime":"true"}'
```
After the DB cluster is restored, you must add the primary (writer) DB instance to it. To create the primary instance for your DB cluster, call the [create-db-instance](https://docs.amazonaws.cn/cli/latest/reference/rds/create-db-instance.html) Amazon CLI command. Include the name of the DB cluster as the `--db-cluster-identifier` parameter value.
