// 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 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.

	// for this parameter uses the same logic that is described in [Authenticating Requests: Using Query Parameters (Amazon Web Services 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.
