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 S3 Glacier
generates vault inventories approximately daily. For more information,
see Downloading a Vault Inventory in Amazon S3 Glacier.
