Just to clarify, Journal Based Backup only backs up objects which have changed based on solely on the contents of the change journal maintained by the journal service.
The change journal is maintained based on change notifications reported by the filesystem. Traditional incremental backup must build the entire list of objects for the local file system and the entire list of objects stored on the server file space for that file system and compare the two lists to derive a list of backup candidates. Note that the above is done regardless of how many objects are actually backed up, if only one object changes both lists must still be built and processed.
