Container for the parameters to the InitiateJob operation. This operation initiates a job of the specified type. In this release, you can initiate a job to retrieve either an archive or a vault inventory (a list of archives in a vault).

Retrieving data from Amazon Glacier is a two-step process:

  1. Initiate a retrieval job.

    A data retrieval policy can cause your initiate retrieval job request to fail with a PolicyEnforcedException exception. For more information about data retrieval policies, see Amazon Glacier Data Retrieval Policies. For more information about the PolicyEnforcedException exception, see Error Responses.

  2. After the job completes, download the bytes.

The retrieval request is executed asynchronously. When you initiate a retrieval job, Amazon Glacier creates a job and returns a job ID in the response. When Amazon Glacier completes the job, you can get the job output (archive or inventory data). For information about getting job output, see GetJobOutput operation.

The job must complete before you can get its output. To determine when a job is complete, you have the following options:

The information you get via notification is same that you get by calling DescribeJob.

If for a specific event, you add both the notification configuration on the vault and also specify an SNS topic in your initiate job request, Amazon Glacier sends both notifications. For more information, see SetVaultNotifications.

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).

About the Vault Inventory

Amazon Glacier prepares an inventory for each vault periodically, every 24 hours. When you initiate a job for a vault inventory, Amazon Glacier returns the last inventory for the vault. The inventory data you get might be up to a day or two days old. Also, the initiate inventory job might take some time to complete before you can download the vault inventory. So you do not want to retrieve a vault inventory for each vault operation. However, in some scenarios, you might find the vault inventory useful. For example, when you upload an archive, you can provide an archive description but not an archive name. Amazon Glacier provides you a unique archive ID, an opaque string of characters. So, you might maintain your own database that maps archive names to their corresponding Amazon Glacier assigned archive IDs. You might find the vault inventory useful in the event you need to reconcile information in your database with the actual vault inventory.

Range Inventory Retrieval

You can limit the number of inventory items retrieved by filtering on the archive creation date or by setting a limit.

Filtering by Archive Creation Date

You can retrieve inventory items for archives created between StartDate and EndDate by specifying values for these parameters in the InitiateJob request. Archives created on or after the StartDate and before the EndDate will be returned. If you only provide the StartDate without the EndDate, you will retrieve the inventory for all archives created on or after the StartDate. If you only provide the EndDate without the StartDate, you will get back the inventory for all archives created before the EndDate.

Limiting Inventory Items per Retrieval

You can limit the number of inventory items returned by setting the Limit parameter in the InitiateJob request. The inventory job output will contain inventory items up to the specified Limit. If there are more inventory items available, the result is paginated. After a job is complete you can use the DescribeJob operation to get a marker that you use in a subsequent InitiateJob request. The marker will indicate the starting point to retrieve the next set of inventory items. You can page through your entire inventory by repeatedly making InitiateJob requests with the marker from the previous DescribeJob output, until you get a marker from DescribeJob that returns null, indicating that there are no more inventory items available.

You can use the Limit parameter together with the date range parameters.

About Ranged Archive Retrieval

You can initiate an archive retrieval for the whole archive or a range of the archive. In the case of ranged archive retrieval, you specify a byte range to return or the whole archive. The range specified must be megabyte (MB) aligned, that is the range start value must be divisible by 1 MB and range end value plus 1 must be divisible by 1 MB or equal the end of the archive. If the ranged archive retrieval is not megabyte aligned, this operation returns a 400 response. Furthermore, to ensure you get checksum values for data you download using Get Job Output API, the range must be tree hash aligned.

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).

Expedited and Bulk Archive Retrievals

When retrieving an archive, you can specify one of the following options in the Tier field of the request body:

The InitiateJobRequest type exposes the following members

Constructors

NameDescription
Public Method InitiateJobRequest()

Empty constructor used to set properties independently even when a simple constructor is available

Public Method InitiateJobRequest(string, JobParameters)

Instantiates InitiateJobRequest with the parameterized properties

Public Method InitiateJobRequest(string, string, JobParameters)

Instantiates InitiateJobRequest with the parameterized properties

Properties

NameTypeDescription
Public Property 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 '-' (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.

Public Property JobParameters Amazon.Glacier.Model.JobParameters

Gets and sets the property JobParameters.

Provides options for specifying job information.

Public Property VaultName System.String

Gets and sets the property VaultName.

The name of the vault.
