As you've discovered, the way you are using COPY TO is creating a free table.

To help you solve your problem, tell us: do you want to back the data up to a table that is in the same dbc as the original table?

Let's say you have a DBC called MyDBC and a table called MyTable that you want to copy. Then you can do this:

USE MyDBC!MyTable  && Notice, the "MyDBC!" is usually not needed
COPY STRUCTURE EXTENDED TO tmpstru
CREATE myCopy DATABASE myDBC NAME MyCopyOfMyTable FROM tmpstru 
APPEND FROM MyTable

HTH

P.S. Unless you're typing commands, capitalization is interpreted as shouting (and rude).
