Copying backups to another Amazon Web Services Region - Amazon Redshift
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Copying backups to another Amazon Web Services Region

You can configure Amazon Redshift Serverless to automatically copy snapshots and recovery points to another Amazon Web Services Region. When you create a snapshot in the source Amazon Web Services Region, it's copied to a destination Region. You can configure your namespace so that it only copies snapshots and recovery points to one destination Amazon Web Services Region at a time. For a list of Amazon Web Services Regions where Amazon Redshift Serverless is available, see the endpoints listed for Redshift Serverless API in the Amazon Web Services General Reference.

When you configure copying backups, you can also specify a retention period of how long Amazon Redshift Serverless should keep the copied snapshot. You can't change the retention periods of recovery points, which must be 1 day. The retention periods of snapshots in the destination Region is separate from the retention period of the snapshot in the source Region. By default, the retention period is to keep the snapshot indefinitely. If you choose Custom value choose the number of days. This amount you choose must be between 1-3653 days, inclusive.

To change the destination Region to copy snapshots to, first disable copying backups, and then specify the new destination Region when you re-enable copying.

Once a snapshot or recovery point is copied to a destination Region, you can use it to restore data to the Region.

By default, your data is encrypted with a key that Amazon manages for you. To use a different key, choose the key that you want to use when configuring backup copying in the source Amazon Web Services Region, and Amazon Redshift Serverless automatically creates a grant, which enables snapshot encryption in the destination Amazon Web Services Region.

To copy backups to another Region, make sure that you have the following IAM permissions:

redshift-serverless:CreateSnapshotCopyConfiguration
redshift-serverless:UpdateSnapshotCopyConfiguration
redshift-serverless:ListSnapshotCopyConfigurations
redshift-serverless:DeleteSnapshotCopyConfiguration

If you're using your own KMS key to encrypt your backups, you also need the following permissions:

kms:CreateGrant
kms:DescribeKey
