Craeting special backup

Hi,
I'd like to create a backup CD which can be - somehow - searched or at least
appended to the live db. I mean a backup of data older then 5 years. If the
customer needs to search something in the old data he should simply insert
the CD, attach it to the database and perform his/her search. After
completing his/her work disattaches the CD and goes on.

Is there any way to do this? Or I have to insert the the old data to the db
and then delete(+vacuum) it?

Thank you all in advance.

Best Regards,
-- Együd Csaba
