A job ID will not expire for at least 24 hours after Amazon Glacier completes the job. That is, you can download the job output within the 24 hours period after Amazon Glacier completes the job.
If the job output is large, then you can use the
Range request header
to retrieve a portion of the output. This allows you to download the entire output
in smaller chunks of bytes. For example, suppose you have 1 GB of job output you want
to download and you decide to download 128 MB chunks of data at a time, which is a
total of eight Get Job Output requests. You use the following process to download
the job output:
Download a 128 MB chunk of output by specifying the appropriate byte range using the
Along with the data, the response includes a SHA256 tree hash of the payload. You compute the checksum of the payload on the client and compare it with the checksum you received in the response to ensure you received all the expected data.
Repeat steps 1 and 2 for all the eight 128 MB chunks of output data, each time specifying the appropriate byte range.
After downloading all the parts of the job output, you have a list of eight checksum values. Compute the tree hash of these values to find the checksum of the entire output. Using the DescribeJob API, obtain job information of the job that provided you the output. The response includes the checksum of the entire archive stored in Amazon Glacier. You compare this value with the checksum you computed to ensure you have downloaded the entire archive content with no errors.
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).

public class GetJobOutputRequest : AmazonGlacierRequest IRequestEvents
The GetJobOutputRequest type exposes the following members
|GetJobOutputRequest()||Empty constructor used to set properties independently even when a simple constructor is available|
|GetJobOutputRequest(string, string, string)||Instantiates GetJobOutputRequest with the parameterized properties|
|GetJobOutputRequest(string, string, string, string)||Instantiates GetJobOutputRequest with the parameterized properties|
Gets and sets the property AccountId.
Gets and sets the property JobId.
The job ID whose data is downloaded.
Gets and sets the property Range.
The range of bytes to retrieve from the output. For example, if you want to download the first 1,048,576 bytes, specify "Range: bytes=0-1048575". By default, this operation downloads the entire output.
Gets and sets the property VaultName.
The name of the vault.
