You almost answered your own question: Archive bit, modification time, ntfs
change journal.
But there are a few options to influence the selection, such as the
environment variable NSR_AVOID_ARCHIVE and/or deleting the change journal.
Pse note that the change journal is always activated if the indexing service
is started on the client, but I can't say for sure what networker does when
the change journal has not been activated through networker.

Subject: [Networker] How does NetWorker decide if a file has changed or
not?


Dear all,
Does anybody know how NetWorker decides on the changed files?
What is the working algorithm behind the incremental backups?
I know that you can make NetWorker use modify date by a directive,
or make it use the NTFS change log.
But in the normal case what does it use?  If it is only the size, than it
would
be too simple :)

Best regards,

Richard E. PEKAR
