Objects stored in a storage system (such as a file server system) are protected by multiple levels of validation. Each chunk of an object is associated with a chunk validator, and an object validator is computed for the object based on the chunk validators. The object validator is stored in the storage system and may be used at various times to validate the object, for example, upon a startup of the storage system, upon taking a checkpoint or "snapshot" of the status of the storage system, or at other appropriate times.
