S3.Client.upload_part_copy(**kwargs)¶Uploads a part by copying data from an existing object as data source. You specify the data source by adding the request header x-amz-copy-source in your request and a byte range by adding 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 .
Note
Instead of using an existing object as part data, you might use the UploadPart action and provide data in your request.
You must initiate a multipart upload before you can upload any part. In response to your initiate request. Amazon S3 returns a unique identifier, the upload ID, that you must include in your upload part request.
For more information about using the UploadPartCopy operation, see the following:
UploadPartCopy operation, see CopyObject and UploadPart.Note the following additional considerations about the request headers x-amz-copy-source-if-match , x-amz-copy-source-if-none-match , x-amz-copy-source-if-unmodified-since , and x-amz-copy-source-if-modified-since :
x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request as follows: x-amz-copy-source-if-match condition evaluates to true , and; x-amz-copy-source-if-unmodified-since condition evaluates to false ; Amazon S3 returns 200 OK and copies the data.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.Versioning
If your bucket has versioning enabled, you could have multiple versions of the same object. By default, x-amz-copy-source identifies the current version of the object to copy. If the current version is a delete marker and you don't specify a versionId in the x-amz-copy-source , Amazon S3 returns a 404 error, because the object does not exist. If you specify versionId in the x-amz-copy-source and the versionId is a delete marker, Amazon S3 returns an HTTP 400 error, because you are not allowed to specify a delete marker as a version for the x-amz-copy-source .
You can optionally specify a specific version of the source object to copy by adding the versionId subresource as shown in the following example:
x-amz-copy-source: /bucket/object?versionId=version idSpecial Errors
- Code: InvalidRequest
- Cause: The specified copy source is not supported as a byte-range copy source.
- HTTP Status Code: 400 Bad Request

[REQUIRED]
The bucket name.
When using this action with an access point, 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 .
When using 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 using this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see Using Amazon S3 on Outposts in the Amazon S3 User Guide .
Bucket key in the copy source dictionary. If you want to provide the copy source for an S3 access point as a string instead of a dictionary, the ARN provided must be the full S3 access point object ARN (i.e. {accesspoint_arn}/object/{key})[REQUIRED]
Object key for which the multipart upload was initiated.
[REQUIRED]
Part number of part being copied. This is a positive integer between 1 and 10,000.
[REQUIRED]
Upload ID identifying the multipart upload whose part is being copied.
x-amz-server-side-encryption-customer-algorithm header. This must be the same encryption key specified in the initiate multipart upload request.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.
Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required

Response Structure
(dict) --
CopySourceVersionId (string) --
The version of the source object that was copied, if you have enabled versioning on the source bucket.

Entity tag of the object.
LastModified (datetime) --
Date and time at which the object was uploaded.
