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
