I've recently moved some data to a different volume and did a full backup after the move. I then updated the permissions of the data in the new volume and as expected, the incremental backup backed-up the data in the new volume.
However, the scheduled incremental that ran last night is still going and it seems to be backing up all the data in the new volume, almost like it had never known it had been backed-up incrementally the previous night. I would expect some of the files to have been changed since the first incremental but not the whole lot.
I'm guessing this may have something to do with archive bits and NBU thinks the files haven't already been backed-up incrementally.
 
Why would NBU not think the files have been backed-up and keep backing-up all the same files twice in a row?
 
Cheers,
