AWS SDK Version 4 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Container for the parameters to the CopyPart operation. Uploads a part by copying data from an existing object as data source. To specify the data source, you add the request header x-amz-copy-source in your request. To specify a byte range, you add the request header x-amz-copy-source-range in your request.

For information about maximum and minimum part sizes and other multipart upload specifications, see Multipart upload limits in the Amazon S3 User Guide.

Instead of copying data from an existing object as part data, you might use the UploadPart action to upload new data as a part of an object in your request.

You must initiate a multipart upload before you can upload any part. In response to your initiate request, Amazon S3 returns the upload ID, a unique identifier that you must include in your upload part request.

For conceptual information about multipart uploads, see Uploading Objects Using Multipart Upload in the Amazon S3 User Guide. For information about copying objects using a single atomic action vs. a multipart upload, see Operations on Objects in the Amazon S3 User Guide.

Directory buckets - For directory buckets, you must make requests for this API operation to the Zonal endpoint. These endpoints support virtual-hosted-style requests in the format https://bucket_name.s3express-az_id.region.amazonaws.com/key-name. Path-style requests are not supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.

Authentication and authorization

All UploadPartCopy requests must be authenticated and signed by using IAM credentials (access key ID and secret access key for the IAM identities). All headers with the x-amz- prefix, including x-amz-copy-source, must be signed. For more information, see REST Authentication.

Directory buckets - You must use IAM credentials to authenticate and authorize your access to the UploadPartCopy API operation, instead of using the temporary security credentials through the CreateSession API operation.

Amazon Web Services CLI or SDKs handles authentication and authorization on your behalf.

Permissions

You must have READ access to the source object and WRITE access to the destination bucket.

  • General purpose bucket permissions - You must have the permissions in a policy based on the bucket types of your source bucket and destination bucket in an UploadPartCopy operation.

    • If the source object is in a general purpose bucket, you must have the s3:GetObject permission to read the source object that is being copied.

    • If the destination bucket is a general purpose bucket, you must have the s3:PutObject permission to write the object copy to the destination bucket.

    For information about permissions required to use the multipart upload API, see Multipart Upload and Permissions in the Amazon S3 User Guide.

  • Directory bucket permissions - You must have permissions in a bucket policy or an IAM identity-based policy based on the source and destination bucket types in an UploadPartCopy operation.

    • If the source object that you want to copy is in a directory bucket, you must have the s3express:CreateSession permission in the Action element of a policy to read the object . By default, the session is in the ReadWrite mode. If you want to restrict the access, you can explicitly set the s3express:SessionMode condition key to ReadOnly on the copy source bucket.

    • If the copy destination is a directory bucket, you must have the s3express:CreateSession permission in the Action element of a policy to write the object to the destination. The s3express:SessionMode condition key cannot be set to ReadOnly on the copy destination.

    For example policies, see Example bucket policies for S3 Express One Zone and Amazon Web Services Identity and Access Management (IAM) identity-based policies for S3 Express One Zone in the Amazon S3 User Guide.

Encryption

  • General purpose buckets - For information about using server-side encryption with customer-provided encryption keys with the UploadPartCopy operation, see CopyObject and UploadPart.

  • Directory buckets - For directory buckets, only server-side encryption with Amazon S3 managed keys (SSE-S3) (AES256) is supported.

Special errors

  • Error Code: NoSuchUpload

    • Description: The specified multipart upload does not exist. The upload ID might be invalid, or the multipart upload might have been aborted or completed.

    • HTTP Status Code: 404 Not Found

  • Error Code: InvalidRequest

    • Description: The specified copy source is not supported as a byte-range copy source.

    • HTTP Status Code: 400 Bad Request

Properties

NameTypeDescription
Public Property CopySourceServerSideEncryptionCustomerMethod Amazon.S3.ServerSideEncryptionCustomerMethod

Gets and sets the property CopySourceServerSideEncryptionCustomerMethod.

Specifies the algorithm to use when decrypting the source object (for example, AES256).

This functionality is not supported when the source object is in a directory bucket.

Public Property CopySourceServerSideEncryptionCustomerProvidedKey System.String

Gets and sets the property CopySourceServerSideEncryptionCustomerProvidedKey.

Specifies the customer-provided encryption key for Amazon S3 to use to decrypt the source object. The encryption key provided in this header must be one that was used when the source object was created.

This functionality is not supported when the source object is in a directory bucket.

Public Property CopySourceServerSideEncryptionCustomerProvidedKeyMD5 System.String

Gets and sets the property CopySourceServerSideEncryptionCustomerProvidedKeyMD5.

Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

This functionality is not supported when the source object is in a directory bucket.

Public Property DestinationBucket System.String

Gets and sets the property DestinationBucket.

The bucket name.

Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket-name.s3express-zone-id.region-code.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Zone (Availability Zone or Local Zone). Bucket names must follow the format bucket-base-name--zone-id--x-s3 (for example, amzn-s3-demo-bucket--usw2-az1--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.

Copying objects across different Amazon Web Services Regions isn't supported when the source or destination bucket is in Amazon Web Services Local Zones. The source and destination buckets must have the same parent Amazon Web Services Region. Otherwise, you get an HTTP 400 Bad Request error with the error code InvalidRequest.

Access points - When you use this action with an access point for general purpose buckets, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When you use this action with an access point for directory buckets, you must provide the access point name in place of the bucket name. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide.

Object Lambda access points are not supported by directory buckets.

S3 on Outposts - When you use this action with S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When you use this action with S3 on Outposts, the destination bucket must be the Outposts access point ARN or the access point alias. For more information about S3 on Outposts, see What is S3 on Outposts? in the Amazon S3 User Guide.

Public Property DestinationKey System.String

Gets and sets the property DestinationKey.

Public Property ETagsToNotMatch System.Collections.Generic.List<System.String>

Gets and sets the property ETagsToNotMatch.

Copies the object if its entity tag (ETag) is different than the specified ETag.

If both of the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request as follows:

x-amz-copy-source-if-none-match condition evaluates to false, and;

x-amz-copy-source-if-modified-since condition evaluates to true;

Amazon S3 returns 412 Precondition Failed response code.

Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.

Public Property ETagToMatch System.Collections.Generic.List<System.String>

Gets and sets the property ETagToMatch.

Copies the object if its entity tag (ETag) matches the specified tag.
