Amazon Glacier Introduces Vault Lock
Amazon Glacier, which enables long-term storage of mission-critical data, has added Vault Lock. This new feature allows you to lock your vault with a variety of compliance controls that are designed to support such long-term records retention. You can now create a Vault Lock policy on a vault, and after it is locked, the policy cannot be overwritten or deleted.
