Patent abstract

Data within a file system may be protected using a key rotation scheme. The key rotation scheme may include a data key and a metadata key. The data key may be used to encrypt data portions of the file system while the metadata key may be used to encrypt the metadata of the file system. The metadata key may be generated based at least in part on a user input and may be rotated at the end of a key rotation interval.
