You've just about gottit all. There is some concern about this whole thing; currently, you are limited to image backups using NDMP; if you want file-level granularity, you must use NFS mount to access the file system from a supported b/a-client... not as pretty as you'd like, but that's the way it is. Then, too, you are limited to NAS filer; Auspex and other filers are not supported.
The storage pool limitation comes from the format used to store the data; they "invented" a new concept/format for NDMP storage pools, so must be kept segregated from "standard" storage pools; I THINK you can still use "backup stg" command -- but you cannot intermix the different types of primary storage pools in a common copy-pool. IBM/Tivoli is wondering how much market there is to justify expanding this support -- (a) file-level granularity and/or (b) other filers. IMHO, I'd want to see file-level granularity.
