Retrieving Vault Metadata in Amazon Glacier
You can retrieve vault information such as the vault creation date, number of archives in the vault, and the total size of all the archives in the vault. Amazon Glacier provides API calls for you to retrieve this information for a specific vault or all the vaults in a specific region in your account.
If you retrieve a vault list, Amazon Glacier returns the list sorted by the ASCII values of
the vault names. The list contains up to 1,000 vaults. You should always check the response
for a marker at which to continue the list; if there are no more items the marker field is
null. You can optionally limit the number of vaults returned in the
response. If there are more vaults than are returned in the response, the result is
paginated. You need to send additional requests to fetch the next set of vaults.
