On Windows networker looks at the archive attribute of the file.
When you backup a file the archive attribute is removed.
If you open the file and edit it you will notice that the archive attribute 
returns.  This would mean that during an incremental backup the file would be 
backed up again.

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
