Upload Part (PUT uploadID)
This multipart upload operation uploads a part of an archive. You can upload archive parts in any order because in your Upload Part request you specify the range of bytes in the assembled archive that will be uploaded in this part. You can also upload these parts in parallel. You can upload up to 10,000 parts for a multipart upload.
For information about multipart upload, see Uploading Large Archives in Parts (Multipart Upload).
Amazon Glacier rejects your upload part request if any of the following conditions is true:
SHA256 tree hash does not match—To ensure that part data is not corrupted in transmission, you compute a SHA256 tree hash of the part and include it in your request. Upon receiving the part data, Amazon Glacier also computes a SHA256 tree hash. If the two hash values don't match, the operation fails. For information about computing a SHA256 tree hash, see Computing Checksums.
SHA256 linear hash does not match—Required for authorization, you compute a SHA256 linear hash of the entire uploaded payload and include it in your request. For information about computing a SHA256 linear hash, see Computing Checksums.
Part size does not match—The size of each part except the last must match the size that is specified in the corresponding Initiate Multipart Upload (POST multipart-uploads) request. The size of the last part must be the same size as, or smaller than, the specified size.
If you upload a part whose size is smaller than the part size you specified in your initiate multipart upload request and that part is not the last part, then the upload part request will succeed. However, the subsequent Complete Multipart Upload request will fail.
Range does not align—The byte range value in the request does not align with the part size specified in the corresponding initiate request. For example, if you specify a part size of 4194304 bytes (4 MB), then 0 to 4194303 bytes (4 MB —1) and 4194304 (4 MB) to 8388607 (8 MB —1) are valid part ranges. However, if you set a range value of 2 MB to 6 MB, the range does not align with the part size and the upload will fail.
This operation is idempotent. If you upload the same part multiple times, the data included in the most recent request overwrites the previously uploaded data.
You send this HTTP
PUT request to the URI of the upload ID that was returned by
your Initiate Multipart Upload request. Amazon Glacier uses the upload ID to associate
part uploads with a specific multipart upload. The request must include a SHA256 tree
hash of the part data (
x-amz-SHA256-tree-hash header), a SHA256 linear hash of the entire payload (
the byte range (
Content-Range header), and the length of the part in bytes (

AccountId value is the AWS account ID of the account that owns the vault. You can either specify an AWS account ID or optionally a
-' (hyphen), in which case Amazon Glacier uses the AWS account ID associated with the credentials used to sign the request.
If you use an account ID, do not include any hyphens ('-') in the ID.
This operation does not use request parameters.
This operation uses the following request headers, in addition to the request headers that are common to all operations. For more information about the common request headers, see Common Request Headers.
Identifies the length of the part in bytes.
Identifies the range of bytes in the assembled archive that will be uploaded in
this part. Amazon Glacier uses this information to assemble the
archive in the proper sequence. The format of this header

A successful response includes the following response headers, in addition to the response headers that are common to all operations. For more information about common response headers, see Common Response Headers.
The SHA256 tree hash that Amazon Glacier computed for the uploaded part.
This operation does not return a response body.
The following request uploads a 4 MB part. The request sets the byte range to make this the first part in the archive.
The example sends an HTTP
PUT request to upload a 4 MB part. The request is
sent to the URI of the Upload ID that was returned by the Initiate Multipart Upload
Content-Range header identifies the part as the first 4 MB
data part of the archive.

To upload the next part, the procedure is the same; however, you must calculate a new SHA256 tree hash of the part you are uploading and also specify a new byte range to indicate where the part will go in the final assembly. The following request uploads another part using the same upload ID. The request specifies the next 4 MB of the archive after the previous request and a part size of 4 MB.

The parts can be uploaded in any order; Amazon Glacier uses the range specification for each part to determine the order in which to assemble them.
