Abstract
Recording file events in change logs while incrementally backing up file systems is described. A system begins incrementally backing up a file system by reading a current change log. The system identifies a file event associated with the file system while incrementally backing up the file system. The system identifies a unique identifier associated with the file event. The system determines whether the unique identifier associated with the file event is greater than a unique identifier offset associated with reading the current change log. The system records the file event in the current change log in response to a determination that the unique identifier associated with the file event is greater than the unique identifier associated with reading the current change log.
