CopySnapshot - Amazon Elastic Compute Cloud
Request ParametersResponse ElementsErrorsExamplesSee Also

CopySnapshot

Copies a point-in-time snapshot of an EBS volume and stores it in Amazon S3. You can copy a snapshot within the same Region, from one Region to another, or from a Region to an Outpost. You can't copy a snapshot from an Outpost to a Region, from one Outpost to another, or within the same Outpost.

You can use the snapshot to create EBS volumes or Amazon Machine Images (AMIs).

When copying snapshots to a Region, copies of encrypted EBS snapshots remain encrypted. Copies of unencrypted snapshots remain unencrypted, unless you enable encryption for the snapshot copy operation. By default, encrypted snapshot copies use the default AWS KMS key; however, you can specify a different KMS key. To copy an encrypted snapshot that has been shared from another account, you must have permissions for the KMS key used to encrypt the snapshot.

Snapshots copied to an Outpost are encrypted by default using the default encryption key for the Region, or a different key that you specify in the request using KmsKeyId. Outposts do not support unencrypted snapshots. For more information, Amazon EBS local snapshots on Outposts in the Amazon EBS User Guide.

Snapshots created by copying another snapshot have an arbitrary volume ID that should not be used for any purpose.

For more information, see Copy an Amazon EBS snapshot in the Amazon EBS User Guide.

Request Parameters

The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see Common Query Parameters.

Description

A description for the EBS snapshot.

Type: String

Required: No

DestinationOutpostArn

The Amazon Resource Name (ARN) of the Outpost to which to copy the snapshot. Only specify this parameter when copying a snapshot from an AWS Region to an Outpost. The snapshot must be in the Region for the destination Outpost. You cannot copy a snapshot from an Outpost to a Region, from one Outpost to another, or within the same Outpost.

For more information, see Copy snapshots from an AWS Region to an Outpost in the Amazon EBS User Guide.

Type: String

Required: No

DestinationRegion

The destination Region to use in the PresignedUrl parameter of a snapshot copy operation. This parameter is only valid for specifying the destination Region in a PresignedUrl parameter, where it is required.

The snapshot copy is sent to the regional endpoint that you sent the HTTP request to (for example, ec2.us-east-1.amazonaws.com).

Type: String

Required: No

DryRun

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

Type: Boolean

Required: No

Encrypted

To encrypt a copy of an unencrypted snapshot if encryption by default is not enabled, enable encryption using this parameter. Otherwise, omit this parameter. Encrypted snapshots are encrypted, even if you omit this parameter and encryption by default is not enabled. You cannot set this parameter to false. For more information, see Amazon EBS encryption in the Amazon EBS User Guide.

Type: Boolean

Required: No

KmsKeyId

The identifier of the AWS KMS key to use for Amazon EBS encryption. If this parameter is not specified, your AWS KMS key for Amazon EBS is used. If KmsKeyId is specified, the encrypted state must be true.

You can specify the KMS key using any of the following:

  • Key ID. For example, 1234abcd-12ab-34cd-56ef-1234567890ab.

  • Key alias. For example, alias/ExampleAlias.

  • Key ARN. For example, arn:aws:kms:us-east-1:012345678910:key/1234abcd-12ab-34cd-56ef-1234567890ab.

  • Alias ARN. For example, arn:aws:kms:us-east-1:012345678910:alias/ExampleAlias.

AWS authenticates the KMS key asynchronously. Therefore, if you specify an ID, alias, or ARN that is not valid, the action can appear to complete, but eventually fails.

Type: String

Required: No

PresignedUrl

When you copy an encrypted source snapshot using the Amazon EC2 Query API, you must supply a pre-signed URL. This parameter is optional for unencrypted snapshots. For more information, see Query requests.

The PresignedUrl should use the snapshot source endpoint, the CopySnapshot action, and include the SourceRegion, SourceSnapshotId, and DestinationRegion parameters. The PresignedUrl must be signed using AWS Signature Version 4. Because EBS snapshots are stored in Amazon S3, the signing algorithm for this parameter uses the same logic that is described in Authenticating Requests: Using Query Parameters (AWS Signature Version 4) in the Amazon S3 API Reference. An invalid or improperly signed PresignedUrl will cause the copy operation to fail asynchronously, and the snapshot will move to an error state.

Type: String

Required: No

SourceRegion

The ID of the Region that contains the snapshot to be copied.

Type: String

Required: Yes

SourceSnapshotId

The ID of the EBS snapshot to copy.

Type: String

Required: Yes

TagSpecification.N

The tags to apply to the new snapshot.

Type: Array of TagSpecification objects

Required: No

Response Elements

The following elements are returned by the service.

requestId

The ID of the request.

Type: String

snapshotId

The ID of the new snapshot.

Type: String

tagSet

Any tags applied to the new snapshot.

Type: Array of Tag objects

Errors

For information about the errors that are common to all actions, see Common client error codes.
