1. A system for recording file events in change logs while incrementally backing up file systems, the system comprising: a processor-based application, which executed on a computer, will cause the processor to: back up a file system incrementally by reading a current change log; identify a file event associated with the file system, the file event occurring during the incremental back up of the file system; identify a unique identifier associated with the identified file event; determine whether the unique identifier associated with the file event is greater than a unique identifier associated with reading the current change log; and record the file event in the current change log during the incremental backup of the file system 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.
