copy-snapshot

Description

Copies a point-in-time snapshot of an EBS volume and stores it in Amazon S3. You can copy the snapshot within the same region or from one region to another. You can use the snapshot to create EBS volumes or Amazon Machine Images (AMIs). The snapshot is copied to the regional endpoint that you send the HTTP request to.

Copies of encrypted EBS snapshots remain encrypted. Copies of unencrypted snapshots remain unencrypted, unless the Encrypted flag is specified during the snapshot copy operation. By default, encrypted snapshot copies use the default AWS Key Management Service (AWS KMS) customer master key (CMK); however, you can specify a non-default CMK with the KmsKeyId parameter.

Note

To copy an encrypted snapshot that has been shared from another account, you must have permissions for the CMK used to encrypt the snapshot.

Note

Snapshots created by the copy-snapshot action have an arbitrary volume ID that should not be used for any purpose.

For more information, see Copying an Amazon EBS Snapshot in the Amazon Elastic Compute Cloud User Guide .

Options

--description (string)

A description for the EBS snapshot.

--destination-region (string)

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.

Note

copy-snapshot sends the snapshot copy to the regional endpoint that you send the HTTP request to, such as ec2.us-east-1.amazonaws.com (in the AWS CLI, this is specified with the --region parameter or the default region in your AWS configuration file).

--encrypted | --no-encrypted (boolean)

Specifies whether the destination snapshot should be encrypted. You can encrypt a copy of an unencrypted snapshot using this flag, but you cannot use it to create an unencrypted copy from an encrypted snapshot. Your default CMK for EBS is used unless a non-default AWS Key Management Service (AWS KMS) CMK is specified with KmsKeyId . For more information, see Amazon EBS Encryption in the Amazon Elastic Compute Cloud User Guide .

--kms-key-id (string)

The full ARN of the AWS Key Management Service (AWS KMS) CMK to use when creating the snapshot copy. This parameter is only required if you want to use a non-default CMK; if this parameter is not specified, the default CMK for EBS is used. The ARN contains the arn:aws:kms namespace, followed by the region of the CMK, the AWS account ID of the CMK owner, the key namespace, and then the CMK ID. For example, arn:aws:kms:us-east-1 :012345678910 :key/abcd1234-a123-456a-a12b-a123b4cd56ef . The specified CMK must exist in the region that the snapshot is being copied to. If a KmsKeyId is specified, the Encrypted flag must also be set.

--presigned-url (string)

The pre-signed URL that facilitates copying an encrypted snapshot. This parameter is only required when copying an encrypted snapshot with the Amazon EC2 Query API; it is available as an optional parameter in all other cases. The PresignedUrl should use the snapshot source endpoint, the copy-snapshot 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 by Using Query Parameters (AWS Signature Version 4) in the Amazon Simple Storage Service 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.

--source-region (string)

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

--source-snapshot-id (string)

The ID of the EBS snapshot to copy.

--dry-run | --no-dry-run (boolean)

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 .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Examples

To copy a snapshot

This example command copies a snapshot with the snapshot ID of snap-066877671789bd71b from the us-west-2 region to the us-east-1 region and adds a short description to identify the snapshot.

Command:

aws --region us-east-1 ec2 copy-snapshot --source-region us-west-2 --source-snapshot-id snap-066877671789bd71b --description "This is my copied snapshot."

Output:

{
    "SnapshotId": "snap-066877671789bd71b"
}

Output

SnapshotId -> (string)

The ID of the new snapshot.
