Hello Russell,

Terry was right about directive on NDMP. Aslo, if you want to breakup into
two diffrent jobs inyour case is NOT work. You need two vol..

ie vol/vol0 and vol/vol1 then it will work.

ALso you would be able to setup backup jobs at them same time, but in
different vol.

Hopes that help.

Vinh
