initiate-multipart-upload

Description

This operation initiates a multipart upload. Amazon S3 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.

Note

You don't need to know the size of the archive when you start a multipart upload because Amazon S3 Glacier does not require you to specify the overall archive size.

After you complete the multipart upload, Amazon S3 Glacier (Glacier) removes the multipart upload resource referenced by the ID. 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) .

For conceptual information and underlying REST API, see Uploading Large Archives in Parts (Multipart Upload) and Initiate Multipart Upload in the Amazon Glacier Developer Guide .

Options

--account-id (string)

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 '- ' (hyphen), in which case Amazon S3 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.

--vault-name (string)

The name of the vault.

--archive-description (string)

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).

--part-size (string)

The size of each part except the last, in bytes. The last part can be smaller than this part size.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

The following command initiates a multipart upload to a vault named my-vault with a part size of 1 MiB (1024 x 1024 bytes) per file:

aws glacier initiate-multipart-upload --account-id - --part-size 1048576 --vault-name my-vault --archive-description "multipart upload test"

The archive description parameter is optional. Amazon Glacier requires an account ID argument when performing operations, but you can use a hyphen to specify the in-use account.

This command outputs an upload ID when successful. Use the upload ID when uploading each part of your archive with aws glacier upload-multipart-part. For more information on multipart uploads to Amazon Glacier using the AWS CLI, see Using Amazon Glacier in the AWS CLI User Guide.

Output

location -> (string)

The relative URI path of the multipart upload ID Amazon S3 Glacier created.

uploadId -> (string)

The ID of the multipart upload. This value is also included as part of the location.
