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.
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.
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.
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.
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
Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.
The following operations are related to UploadPartCopy:
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginCopyPart and EndCopyPart.
Namespace: Amazon.S3
Assembly: AWSSDK.S3.dll
Version: 3.x.y.z
public abstract Task<CopyPartResponse> CopyPartAsync( String sourceBucket, String sourceKey, String destinationBucket, String destinationKey, String uploadId, CancellationToken cancellationToken )
A property of CopyPartRequest used to execute the CopyPart service method.
A property of CopyPartRequest used to execute the CopyPart service method.
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-az_id.region.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the format bucket_base_name--az-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az1--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide. Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. 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. Access points and Object Lambda access points are not supported by directory buckets. S3 on Outposts - When you use this action with Amazon 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 through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.
A property of CopyPartRequest used to execute the CopyPart service method.
Upload ID identifying the multipart upload whose part is being copied.
A cancellation token that can be used by other objects or threads to receive notice of cancellation.
