InitiateMultipartUploadRequest Class

Container for the parameters to the InitiateMultipartUpload operation. This operation initiates a multipart upload. Amazon Glacier creates a multipart upload resource and returns its ID in the response. The multipart upload ID is used in subsequent requests to upload parts of an archive (see UploadMultipartPart).

When you initiate a multipart upload, you specify the part size in number of bytes. The part size must be a megabyte (1024 KB) multiplied by a power of 2-for example, 1048576 (1 MB), 2097152 (2 MB), 4194304 (4 MB), 8388608 (8 MB), and so on. The minimum allowable part size is 1 MB, and the maximum is 4 GB.

Every part you upload to this resource (see UploadMultipartPart), except the last one, must have the same size. The last one can be the same size or smaller. For example, suppose you want to upload a 16.2 MB file. If you initiate the multipart upload with a part size of 4 MB, you will upload four parts of 4 MB each and one part of 0.2 MB.

You don't need to know the size of the archive when you start a multipart upload because Amazon Glacier does not require you to specify the overall archive size.

After you complete the multipart upload, Amazon Glacier removes the multipart upload resource referenced by the ID. Amazon Glacier also removes the multipart upload resource if you cancel the multipart upload or it may be removed if there is no activity for a period of 24 hours.

An AWS account has full permission to perform all operations (actions). However, AWS Identity and Access Management (IAM) users don't have any permissions by default. You must grant them explicit permission to perform specific actions. For more information, see Access Control Using AWS Identity and Access Management (IAM).

The InitiateMultipartUploadRequest type exposes the following members

Constructors

	Name	Description
	InitiateMultipartUploadRequest()	Empty constructor used to set properties independently even when a simple constructor is available
	InitiateMultipartUploadRequest(string, string, Int64)	Instantiates InitiateMultipartUploadRequest with the parameterized properties
	InitiateMultipartUploadRequest(string, string, string, Int64)	Instantiates InitiateMultipartUploadRequest with the parameterized properties

Properties

Name	Type	Description
AccountId	System.String	Gets and sets the property AccountId. The `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 single apos`-`apos (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 (apos-apos) in the ID.
ArchiveDescription	System.String	Gets and sets the property ArchiveDescription. The archive description that you are uploading in parts. The part size must be a megabyte (1024 KB) multiplied by a power of 2, for example 1048576 (1 MB), 2097152 (2 MB), 4194304 (4 MB), 8388608 (8 MB), and so on. The minimum allowable part size is 1 MB, and the maximum is 4 GB (4096 MB).
PartSize	System.Int64	Gets and sets the property PartSize. The size of each part except the last, in bytes. The last part can be smaller than this part size.
VaultName	System.String	Gets and sets the property VaultName. The name of the vault.
