I wouldn't be so sure. 16 million files is rather a lot for a single job
- it's an average of ~66KB per file for that job. (Although I back up
about 8 million in 9 hours using multilple concurrent jobs, reading from
28 disks concurrently). Backing up small files is inefficient as the
disk has to seek all over the place.
I suggest that you try this first:
time tar cf /dev/null /the/directory/you/are/backing/up
Then you should be able to work out whether its the Netapp limiting the
back up speed, rather than bacula.
