    摘要: The disclosed embodiments provide a system for managing access to a remote storage system. During operation, the system receives a first request from a user to write a file to a remote storage system. Next, the system receives a first encrypted version of the file from a client associated with the first request. The system then decrypts the first encrypted version to obtain an unencrypted version of the file and uses the unencrypted version to generate a second encrypted version of the file. Finally, the system writes the second encrypted version to a file store and stores metadata for the file in a virtual filesystem that is physically separate from the file store.
