Natively, it is not possible. It can be done using some "tricks"

Full dumps are NOT scheduled, that is Amanda that decide when to full
dump, depending on the load of the system (wouldn't do all full dumps
the same day and nothing the other days).

Yes you need a light version of Amanda on the clients (plus at least a
valid version of GNU tar if you are to use GNU tar).

It does not use smbmount, but instead smbclient and the tar command
included to smbclient. It works with the mentionned limitations about
open files, naming of share, users and password (keep them all to
alphanumerical). These limitations are due to a conjunction of Windows
limitations, Samba limitations and Unix shell limitations.
It DOES put some load on the Windows client.
