Using Boto to tell when a file has successfully been uploaded to Glacier

Take a look at this Boto and Glacier guide, you can either poll it manually from boto or you can set up Amazon Simple Notification Service to notify you when the job is done.

archive_id = vault.upload_archive("mybackup.tgz")
retrieve_job = vault.retrieve_archive(archive_id)

# if the job is in progress
job_id = retrieve_job.id
retrieve_job = vault.get_job(job_id)

if retrieve_job.completed:
    job.download_to_file("mybackup.tgz")

You can use boto's set_vault_notifications function set the SNS notifications.

notification_config = {'SNSTopic': 'my_notification_topic',
                       'Events': ['ArchiveRetrievalCompleted',
                                  'InventoryRetrievalCompleted']}
vault.set_vault_notifications(vault, notification_config)

Here is an extensive example of waiting for an upload by setting up SNS notification subscriptions to SQS queue service.
