Copying files from one GDB to another with error reporting.

I was hoping someone here could help me!

I'm trying to write a script that will allow me to transfer files from one GDB to another, excluding lines, and generate an error report in the process. In the arcpy module I've tried using ListFeatureClasses, Describe, and CopyFeatures but I haven't really been able to get anywhere. I'd appreciat if someone could point me in the right direction!
