NETWORK 10 & IFS backups

Since upgrading to NETWORK 10 we have been getting the following during our nightly backups of *LINK (Save while active):

Message ID . . . . . . . . : CPFA09E
Message . . . . : Object in use. Object is /Help Systems/Robot
NETWORK/logs/netnodelog.log.
Cause . . . . . : An operation attempted to use object /Help Systems
NETWORK/logs/netnodelog.log. This object is currently in use.

Sometimes it is netnodelog.log, sometimes netnodeboot.log, and sometimes both. Is there anything we can do besides an omit or shutting down Network to get a clean backup of the logs?
