I have both backup options enabled in CWP and it works perfectly.  I have a specific need to backup via rsync to another location as well.  Is it possible to do this with the existing setup?  for example, put a comma after each ip address backup location?  
Or could I duplicate /usr/local/cwp/.conf/remote_backup.conf?  where is the cron that fires all the backup scripts?
I can setup my own script and cron, I just thought it would be nice to use some of the existing code.
