JFS

JFS, or Journaled File System, is a type of computer file system that ensures data integrity and reliability. It records changes in a dedicated journal before making them to the main storage, which helps prevent data corruption if there's a sudden power loss or system crash. This journaling process allows the system to recover more smoothly by referencing the journal to complete or undo incomplete operations. JFS is commonly used in enterprise environments where data accuracy and system stability are critical.
