Both cases are good and will work. Both have advantages and disadvantages,
i.e. NFS is not as efficient as Bacula communication protocol, especially
when you will backup a lot of files (a fileserver, in example :) ), but if
you need to compress or encrypt your data then using NFS allow you to move
compress or encryption computations from fileserver to backup server, etc.
You have to check what is best for you.

What hashing do you mean? Currently Bacula can perform MD5 or SHA1 file
digest computation during backup. It is performed on client side and cannot
be moved to backup server.

Great, then NFS will be your friend.

It sounds like block level data deduplication which is not currently
available.

Yes it is. It is called "deduplication on source". Bacula currently has
deduplication on source (base jobs) but it works completely different then
that.
BTW. You should ask above questions which are not related to Bacula
development on bacula-users list instead of bacula-devel. Do this next time.
