Stopping a StoreOnce copy erroring off falsely?

So I have a line in cron that run a copy every hour.

# Copy the archive logs over to Fenton hourly

13 * * * * /opt/omni/bin/omniobjcopy -replist Hourly_Archive_Log_Copy -scheduled > /tmp/objcopy.$$ 2>&1

 

NOW we get an alarm if there is nothing to copy.  THAT is not an error.  How do I make DP NOT report it?  Folks will get paged for a false alarm.  Is there a way to check for objects before I attempt a copy?

No objects to copy. The session will abort.

 

This is from the man page but an example might be nice:

 

To obtain the information about all backed up objects or sessions

containing the objects you want to copy, use the omnidb command.
