Abstract

An object storage system provides a storage object to support index structures, logs, and audit trails in WORM storage. The storage object includes a mutable object, an immutable object, or an appendable object. For each storage object, the system maintains an indication of type, such as mutable, immutable, or appendable object type. A mutable object can be arbitrarily modified, an immutable object cannot be modified, and the contents of the appendable object cannot be modified but can be appended with new data. Appended data becomes immutable. The system enables a protection level represented by the object type to be upgraded but not downgraded. Consequently, data committed to be immutable cannot be changed by changing the type of the storage object.
