CreateSnapshot - Amazon Elastic Compute Cloud
AWS services or capabilities described in AWS documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with AWS services in China.


Creates a snapshot of an EBS volume and stores it in Amazon S3. You can use snapshots for backups, to make copies of EBS volumes, and to save data before shutting down an instance.

When a snapshot is created, any AWS Marketplace product codes that are associated with the source volume are propagated to the snapshot.

You can take a snapshot of an attached volume that is in use. However, snapshots only capture data that has been written to your EBS volume at the time the snapshot command is issued; this might exclude any data that has been cached by any applications or the operating system. If you can pause any file systems on the volume long enough to take a snapshot, your snapshot should be complete. However, if you cannot pause all file writes to the volume, you should unmount the volume from within the instance, issue the snapshot command, and then remount the volume to ensure a consistent and complete snapshot. You may remount and use your volume while the snapshot status is pending.

To create a snapshot for EBS volumes that serve as root devices, you should stop the instance before taking the snapshot.

Snapshots that are taken from encrypted volumes are automatically encrypted. Volumes that are created from encrypted snapshots are also automatically encrypted. Your encrypted volumes and any associated snapshots always remain protected.

You can tag your snapshots during creation. For more information, see Tagging your Amazon EC2 resources in the Amazon Elastic Compute Cloud User Guide.

For more information, see Amazon Elastic Block Store and Amazon EBS encryption in the Amazon Elastic Compute Cloud 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.


A description for the snapshot.

Type: String

Required: No


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


The tags to apply to the snapshot during creation.

Type: Array of TagSpecification objects

Required: No


The ID of the EBS volume.

Type: String

Required: Yes

Response Elements

The following elements are returned by the service.


The data encryption key identifier for the snapshot. This value is a unique identifier that corresponds to the data encryption key that was used to encrypt the original volume or snapshot copy. Because data encryption keys are inherited by volumes created from snapshots, and vice versa, if snapshots share the same data encryption key identifier, then they belong to the same volume/snapshot lineage. This parameter is only returned by DescribeSnapshots.

Type: String


The description for the snapshot.

Type: String


Indicates whether the snapshot is encrypted.

Type: Boolean


The Amazon Resource Name (ARN) of the AWS Key Management Service (AWS KMS) customer master key (CMK) that was used to protect the volume encryption key for the parent volume.

Type: String


The AWS owner alias, from an Amazon-maintained list (amazon). This is not the user-configured AWS account alias set using the IAM console.

Type: String


The AWS account ID of the EBS snapshot owner.

Type: String


The progress of the snapshot, as a percentage.

Type: String


The ID of the request.

Type: String


The ID of the snapshot. Each snapshot receives a unique identifier when it is created.

Type: String


The time stamp when the snapshot was initiated.

Type: Timestamp


The snapshot state.

Type: String

Valid Values: pending | completed | error


Encrypted Amazon EBS snapshots are copied asynchronously. If a snapshot copy operation fails (for example, if the proper AWS Key Management Service (AWS KMS) permissions are not obtained) this field displays error state details to help you diagnose why the error occurred. This parameter is only returned by DescribeSnapshots.

Type: String


Any tags assigned to the snapshot.

Type: Array of Tag objects


The ID of the volume that was used to create the snapshot. Snapshots created by the CopySnapshot action have an arbitrary volume ID that should not be used for any purpose.

Type: String


The size of the volume, in GiB.

Type: Integer


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



This example creates a snapshot of the volume with the ID vol-1234567890abcdef0.
