A system and method for determining file system data integrity. In one embodiment, the system includes a storage device configured to store data and a file system configured to manage access to the storage device, to store plurality of files, to store a respective signature of each of the plurality of files, and to compare a respective signature of a given file against a corresponding validation signature. In one specific implementation, the system further includes a validation signature inventory including a plurality of validation signatures, and the file system is further configured to validate a particular file by retrieving a corresponding particular validation signature from the validation signature inventory and comparing the corresponding particular validation signature against the respective signature of the particular file. In another specific implementation, the file system is further configured to store the corresponding validation signature of the given file in a write-once storage attribute.
