This operation enables you to check the status of your job. However, it
is strongly recommended that you set up an Amazon SNS topic and specify
it in your initiate job request so that Glacier can notify the topic
after it completes the job.
A job ID will not expire for at least 24 hours after Glacier completes
the job.
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 more information about using this operation, see the documentation
for the underlying REST API Describe Job
in the Amazon Glacier Developer Guide.
