Changes (request)

{'CopyTags': 'boolean', 'KmsKeyId': 'string', 'PreSignedUrl': 'string'}

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 region where you call the CopyDBClusterSnapshot action is the destination region for the encrypted DB cluster snapshot to be copied to. To copy an encrypted DB cluster snapshot from another region, you must provide the following values:

KmsKeyId - The AWS Key Management System (KMS) key identifier for the key to use to encrypt the copy of the DB cluster snapshot in the destination region.
PreSignedUrl - A URL that contains a Signature Version 4 signed request for the CopyDBClusterSnapshot action to be called in the source region where the DB cluster snapshot will be copied from. The pre-signed URL must be a valid request for the CopyDBClusterSnapshot API action that can be executed in the source region that contains the encrypted DB cluster snapshot to be copied. The pre-signed URL request must contain the following parameter values:
- KmsKeyId - The KMS key identifier for the key to use to encrypt the copy of the DB cluster snapshot in the destination region. This is the same identifier for both the CopyDBClusterSnapshot action that is called in the destination region, and the action contained in the pre-signed URL.
- DestinationRegion - The name of the region that the DB cluster snapshot will 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 region. For example, if you are copying an encrypted DB cluster snapshot from the us-west-2 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.

TargetDBClusterSnapshotIdentifier - The identifier for the new copy of the DB cluster snapshot in the destination 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 region and is the same value as the SourceDBClusterSnapshotIdentifier in the pre-signed 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 DB cluster snapshots from one region to another, see Copying a DB Cluster Snapshot in the Same Account, Either in the Same Region or Across Regions in the Amazon RDS User Guide.

For more information on Amazon Aurora, see Aurora on Amazon RDS in the Amazon RDS User Guide.

        },
    ]
)

type SourceDBClusterSnapshotIdentifier

string

param SourceDBClusterSnapshotIdentifier

[REQUIRED]

The identifier of the DB cluster snapshot to copy. This parameter is not case-sensitive.

Constraints:

Must contain from 1 to 63 alphanumeric characters or hyphens.
First character must be a letter.
Cannot end with a hyphen or contain two consecutive hyphens.

Example: my-cluster-snapshot1

type TargetDBClusterSnapshotIdentifier

string

param TargetDBClusterSnapshotIdentifier

[REQUIRED]

The identifier of the new DB cluster snapshot to create from the source DB cluster snapshot. This parameter is not case-sensitive.

Constraints:

Must contain from 1 to 63 alphanumeric characters or hyphens.
First character must be a letter.
Cannot end with a hyphen or contain two consecutive hyphens.

Example: my-cluster-snapshot2

type KmsKeyId

string

param KmsKeyId

The AWS KMS key ID for an encrypted DB cluster snapshot. The KMS key ID is the Amazon Resource Name (ARN), KMS key identifier, or the KMS key alias for the KMS encryption key.

If you copy an unencrypted DB cluster snapshot and specify a value for the KmsKeyId parameter, Amazon RDS encrypts the target DB cluster snapshot using the specified KMS encryption 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 encryption 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 region, you must set KmsKeyId to the KMS key ID you want to use to encrypt the copy of the DB cluster snapshot in the destination region. KMS encryption keys are specific to the region that they are created in, and you cannot use encryption keys from one region in another region.

type PreSignedUrl

string

param PreSignedUrl

The URL that contains a Signature Version 4 signed request for the CopyDBClusterSnapshot API action in the AWS region that contains the source DB cluster snapshot to copy. The PreSignedUrl parameter must be used when copying an encrypted DB cluster snapshot from another AWS region.

The pre-signed URL must be a valid request for the CopyDBSClusterSnapshot API action that can be executed in the source region that contains the encrypted DB cluster snapshot to be copied. The pre-signed URL request must contain the following parameter values:

KmsKeyId - The KMS key identifier for the key to use to encrypt the copy of the DB cluster snapshot in the destination region. This is the same identifier for both the CopyDBClusterSnapshot action that is called in the destination region, and the action contained in the pre-signed URL.
DestinationRegion - The name of the region that the DB cluster snapshot will 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 region. For example, if you are copying an encrypted DB cluster snapshot from the us-west-2 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.

Metadata assigned to an Amazon RDS resource consisting of a key-value pair.
- Key (string) --
  
  A key is the required name of the tag. The string value can be from 1 to 128 Unicode characters in length and cannot be prefixed with "aws:" or "rds:". The string can only contain only the set of Unicode letters, digits, white-space, '_', '.', '/', '=', '+', '-' (Java regex: "^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$").

type StorageEncrypted

boolean

param StorageEncrypted

Specifies whether the DB cluster is encrypted.

type KmsKeyId

string

param KmsKeyId

The KMS key identifier for an encrypted DB cluster.

The KMS key identifier is the Amazon Resource Name (ARN) for the KMS encryption key. If you are creating a DB cluster with the same AWS account that owns the KMS encryption key used to encrypt the new DB cluster, then you can use the KMS key alias instead of the ARN for the KMS encryption key.

If the StorageEncrypted parameter is true, and you do not specify a value for the KmsKeyId parameter, then Amazon RDS will use your default encryption key. AWS KMS creates the default encryption key for your AWS account. Your AWS account has a different default encryption key for each AWS region.

If you create a Read Replica of an encrypted DB cluster in another region, you must set KmsKeyId to a KMS key ID that is valid in the destination region. This key is used to encrypt the Read Replica in that region.

type PreSignedUrl

string

param PreSignedUrl

A URL that contains a Signature Version 4 signed request for the CreateDBCluster action to be called in the source region where the DB cluster will be replicated from. You only need to specify PreSignedUrl when you are performing cross-region replication from an encrypted DB cluster.

The pre-signed URL must be a valid request for the CreateDBCluster API action that can be executed in the source region that contains the encrypted DB cluster to be copied.

The pre-signed URL request must contain the following parameter values:

KmsKeyId - The KMS key identifier for the key to use to encrypt the copy of the DB cluster in the destination region. This should refer to the same KMS key for both the CreateDBCluster action that is called in the destination region, and the action contained in the pre-signed URL.
DestinationRegion - The name of the region that Aurora Read Replica will be created in.
ReplicationSourceIdentifier - The DB cluster identifier for the encrypted DB cluster to be copied. This identifier must be in the Amazon Resource Name (ARN) format for the source region. For example, if you are copying an encrypted DB cluster from the us-west-2 region, then your ReplicationSourceIdentifier would look like Example: arn:aws:rds:us-west-2:123456789012:cluster:aurora-cluster1 .
