'This operation returns information about a vault, including
the vault\'s Amazon Resource Name (ARN), the date the vault was
created, the number of archives it contains, and the total
size of all the archives in the vault. The number of archives
and their total size are as of the last inventory generation.
This means that if you add or remove an archive from a vault,
and then immediately use Describe Vault, the change in
contents will not be immediately reflected. If you want to
retrieve the latest inventory of the vault, use InitiateJob.
Amazon Glacier generates vault inventories approximately
daily. For more information, see `Downloading a Vault
Inventory in Amazon Glacier`_.
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 conceptual information and underlying REST API, go to
`Retrieving Vault Metadata in Amazon Glacier`_ and `Describe
Vault `_ in the Amazon Glacier Developer Guide .
