Problem saving a buffer

Hi to all,
i have made a model within of this i've included buffer toolbox.
I would like the model to create as intermediate value the buffer , and then with copy feature i would like to save the buffer in a file geodatabase on my disk location (es. c:\temp\myfgdb.gdb).
When i launch the model work good and he provide correct result, but when i publish geoprocessing he works good, he creates the buffer in the scratch workspace but he don't copy the feature in location i've choose before.
I tried also setting the workspace environment to c:\temp\myfgdb.gdb during the copy feature.

I don't understand where's the problem , someone have any suggestion ?

There's another way the geoprocess to save the buffer in my file gdb ?

Thanks in advance
