Fred,
You'll have to use Netbackups' restore to get what you're wanting. The other posts are to help you get "Netbackup" files off of the tape, but I can tell from your questioning, that you want your files that were in the HPUX file system. Unless you're a guru in the data layout of Netbackup, or you're lucky enough to find out that the files are mostly text and laid end to end with little to no indexing and formatting and tablature (and they probably are not) then your only method of getting files out of a Netbackup is to run Netbackup restore procedure.
When I say "only" I mean the only straightforward way. Beyond that, you'll probably be writing some C code to retrieve data from the files on the tape in whatever format you figure out Netbackup stores data in.
