// 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 Key Management Service (KMS) 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 (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/snapshots-outposts.html#ami)
// in the Amazon Elastic Compute Cloud 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 (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-copy-snapshot.html)
// in the Amazon Elastic Compute Cloud User Guide.

	// Outpost. You cannot copy a snapshot from an Outpost to a Region, from one

	// For more information, see Amazon EBS encryption (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSEncryption.html)
	// in the Amazon Elastic Compute Cloud User Guide.
	Encrypted *bool

	// The identifier of the Key Management Service (KMS) KMS key to use for Amazon
	// EBS encryption. If this parameter is not specified, your 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.
	// Amazon Web Services 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.
	KmsKeyId *string

	// When you copy an encrypted source snapshot using the Amazon EC2 Query API, you

	// snapshots. For more information, see Query requests (https://docs.aws.amazon.com/AWSEC2/latest/APIReference/Query-Requests.html)
	// . 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 Amazon Web Services 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 (Amazon Web Services Signature Version 4) (https://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-query-string-auth.html)
	// 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.
