Downloads an archive from Amazon Glacier from the specified vault for the current user's account. Saves the archive to the specified file.
This method creates an Amazon SNS topic, and an Amazon SQS queue that is subscribed to that topic. It then initiates the archive retrieval job and polls the queue for the archive to be available. This polling takes about 4 hours. Once the archive is available, download will begin.
Additional options can be set using the UploadDirectoryOptions object. For example, you can set the FilesTransferProgress property to a delegate to track progress.
