I'm NAS-impaired, but you need to do basic looksee...  Do 'dsmc Query
Filespace' to see what viable filespaces the client generally has.
Also do 'Query NASBAckup' in the TSM server to see what it
specifically has.

Pay particular heed to what the Unix client manual says about the
restorability of Full NAS images, in its documentation of the MODE
option.  This may well be your problem.
