  • Using file system extended attributes to update databases in hierarchical file systems
    Patent number: 11853165
    Abstract: Systems and methods are disclosed for reconstructing a file hierarchy by scanning attributes of stored files. Stored files can have a file hierarchy that is maintained in a database stored on a storage device. The files can be stored as objects on the device using a flat file structure. The file database provides the file hierarchy. The systems and methods disclosed herein store information in file system extended attributes for individual storage files such that the database can be reconstructed by scanning the storage files, using values in the extended attributes to recreate the hierarchical database.
    Type: Grant
    Filed: January 28, 2020
    Date of Patent: December 26, 2023
    Assignee: Western Digital Technologies, Inc.
