Jon — you are brilliant!   The backup SERVER’s dump files,  which I did ad hoc 
after all other jobs were done
and just left there sitting on the holding disk,  were indeed the first files 
onto the tape.   What a clever idea!
I did a force on the ad hoc dump,  so the the dump sitting on the holding disk 
was a FULL dump.
Very useful concept.   :D
