aws ec2 create-snapshot
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. You can create snapshots of volumes in a Region and volumes on an Outpost. If you create a snapshot of a volume in a Region, the snapshot must be stored in the same Region as the volume. If you create a snapshot of a volume on an Outpost, the snapshot can be stored on the same Outpost as the volume, or in the Region for that Outpost. 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.

Options
| Name | Description |
|---|---|
--description <string> | A description for the snapshot |
--outpost-arn <string> | The Amazon Resource Name (ARN) of the AWS Outpost on which to create a local snapshot. To create a snapshot of a volume in a Region, omit this parameter. The snapshot is created in the same Region as the volume. To create a snapshot of a volume on an Outpost and store the snapshot in the Region, omit this parameter. The snapshot is created in the Region for the Outpost. To create a snapshot of a volume on an Outpost and store the snapshot on an Outpost, specify the ARN of the destination Outpost. The snapshot must be created on the same Outpost as the volume. For more information, see Creating local snapshots from volumes on an Outpost in the Amazon Elastic Compute Cloud User Guide |
--volume-id <string> | The ID of the EBS volume |
--tag-specifications <list> | The tags to apply to the snapshot during creation |
--dry-run | 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 |
--no-dry-run | 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. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally |
--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 |
