I don't happen to think that "tee" is the right tool here.

The standard way to do this and record the error messages is with redirection.

In standard linux the screen output is from the stdout device and the
error message is printed to the stderr device with a standard screen
setup both stdout and stderr are the screen, but when you are
recording data to a log file for historical needs, you have to
redirect stderr to stdout so that the tee command can actually see it.

add a 2>&1 to the cp command at the end before the pipe, and tee will
get the errors as well.

BTW this is generically true for all POSIX compatible screen based tools.
