CopyDBClusterSnapshot

Copies a snapshot of a DB cluster.

To copy a DB cluster snapshot from a shared manual DB cluster snapshot, SourceDBClusterSnapshotIdentifier must be the Amazon Resource Name (ARN) of the shared DB cluster snapshot.

You can copy an encrypted DB cluster snapshot from another AWS Region. In that case, the AWS Region where you call the CopyDBClusterSnapshot operation is the destination AWS Region for the encrypted DB cluster snapshot to be copied to. To copy an encrypted DB cluster snapshot from another AWS Region, you must provide the following values:

  • KmsKeyId - The AWS Key Management System (AWS KMS) key identifier for the key to use to encrypt the copy of the DB cluster snapshot in the destination AWS Region.

  • TargetDBClusterSnapshotIdentifier - The identifier for the new copy of the DB cluster snapshot in the destination AWS Region.

  • SourceDBClusterSnapshotIdentifier - The DB cluster snapshot identifier for the encrypted DB cluster snapshot to be copied. This identifier must be in the ARN format for the source AWS Region and is the same value as the SourceDBClusterSnapshotIdentifier in the presigned URL.

To cancel the copy operation once it is in progress, delete the target DB cluster snapshot identified by TargetDBClusterSnapshotIdentifier while that DB cluster snapshot is in "copying" status.

For more information on copying encrypted Amazon Aurora DB cluster snapshots from one AWS Region to another, see Copying a Snapshot in the Amazon Aurora User Guide.

For more information on Amazon Aurora DB clusters, see What is Amazon Aurora? in the Amazon Aurora User Guide.

For more information on Multi-AZ DB clusters, see Multi-AZ DB cluster deployments in the Amazon RDS User Guide.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

SourceDBClusterSnapshotIdentifier

The identifier of the DB cluster snapshot to copy. This parameter isn't case-sensitive.

You can't copy an encrypted, shared DB cluster snapshot from one AWS Region to another.

Constraints:

  • Must specify a valid system snapshot in the "available" state.

  • If the source snapshot is in the same AWS Region as the copy, specify a valid DB snapshot identifier.

  • If the source snapshot is in a different AWS Region than the copy, specify a valid DB cluster snapshot ARN. For more information, go to Copying Snapshots Across AWS Regions in the Amazon Aurora User Guide.

Example: my-cluster-snapshot1

Type: String

Required: Yes

TargetDBClusterSnapshotIdentifier

The identifier of the new DB cluster snapshot to create from the source DB cluster snapshot. This parameter isn't case-sensitive.

Constraints:

  • Must contain from 1 to 63 letters, numbers, or hyphens.

  • First character must be a letter.

  • Can't end with a hyphen or contain two consecutive hyphens.

Example: my-cluster-snapshot2

Type: String

Required: Yes

CopyTags

Specifies whether to copy all tags from the source DB cluster snapshot to the target DB cluster snapshot. By default, tags are not copied.

Type: Boolean

Required: No

KmsKeyId

The AWS KMS key identifier for an encrypted DB cluster snapshot. The AWS KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the AWS KMS key.

If you copy an encrypted DB cluster snapshot from your AWS account, you can specify a value for KmsKeyId to encrypt the copy with a new KMS key. If you don't specify a value for KmsKeyId, then the copy of the DB cluster snapshot is encrypted with the same KMS key as the source DB cluster snapshot.

If you copy an encrypted DB cluster snapshot that is shared from another AWS account, then you must specify a value for KmsKeyId.

To copy an encrypted DB cluster snapshot to another AWS Region, you must set KmsKeyId to the AWS KMS key identifier you want to use to encrypt the copy of the DB cluster snapshot in the destination AWS Region. KMS keys are specific to the AWS Region that they are created in, and you can't use KMS keys from one AWS Region in another AWS Region.

If you copy an unencrypted DB cluster snapshot and specify a value for the KmsKeyId parameter, an error is returned.

Type: String

Required: No

PreSignedUrl

When you are copying a DB cluster snapshot from one AWS GovCloud (US) Region to another, the URL that contains a Signature Version 4 signed request for the CopyDBClusterSnapshot API operation in the AWS Region that contains the source DB cluster snapshot to copy. Use the PreSignedUrl parameter when copying an encrypted DB cluster snapshot from another AWS Region. Don't specify PreSignedUrl when copying an encrypted DB cluster snapshot in the same AWS Region.

This setting applies only to AWS GovCloud (US) Regions. It's ignored in other AWS Regions.

The presigned URL must be a valid request for the CopyDBClusterSnapshot API operation that can run in the source AWS Region that contains the encrypted DB cluster snapshot to copy. The presigned URL request must contain the following parameter values:

  • KmsKeyId - The AWS KMS key identifier for the KMS key to use to encrypt the copy of the DB cluster snapshot in the destination AWS Region. This is the same identifier for both the CopyDBClusterSnapshot operation that is called in the destination AWS Region, and the operation contained in the presigned URL.

  • DestinationRegion - The name of the AWS Region that the DB cluster snapshot is to be created in.

  • SourceDBClusterSnapshotIdentifier - The DB cluster snapshot identifier for the encrypted DB cluster snapshot to be copied. This identifier must be in the Amazon Resource Name (ARN) format for the source AWS Region. For example, if you are copying an encrypted DB cluster snapshot from the us-west-2 AWS Region, then your SourceDBClusterSnapshotIdentifier looks like the following example: arn:aws:rds:us-west-2:123456789012:cluster-snapshot:aurora-cluster1-snapshot-20161115.

To learn how to generate a Signature Version 4 signed request, see Authenticating Requests: Using Query Parameters (AWS Signature Version 4) and Signature Version 4 Signing Process.

Note

If you are using an AWS SDK tool or the AWS CLI, you can specify SourceRegion (or --source-region for the AWS CLI) instead of specifying PreSignedUrl manually. Specifying SourceRegion autogenerates a presigned URL that is a valid request for the operation that can run in the source AWS Region.

Type: String

Required: No

Tags.Tag.N

A list of tags.

For more information, see Tagging Amazon RDS resources in the Amazon RDS User Guide or Tagging Amazon Aurora and Amazon RDS resources in the Amazon Aurora User Guide.

Type: Array of Tag objects

Required: No
