Can you carry hpv virus for over 30yrs? can you have a negative hpv test 2yrs prior to positive ?if so, does that mean you just became infected?

Yes, yes, and yes: Yes, you can have hpv for over 30+ years. Any person who has been sexually active with another person ever in their lifetime likely has been exposed to hpv. This is why there has been a push to get young children vaccinated before they become sexually active. If your hpv test was negative 2 years ago but then became positive, then you likely did get infected with hpv within those 2 years.
