I am not sure what you want to achieve, but if you want just to Backup, 
maybe specialized Backup Software like Bacula (http://www.bacula.org/) 
could be a better solution for you (Sorry, could not resist ;-)

That said, if you want to do it that way, my exclude list (maybe) could 
be:

/etc/mtab
/etc/ssh/*_key{,.pub}
/etc/hosts (maybe)
/etc/sysconfig/network-scripts/ifcfg-*
/etc/sysconfig/network-scripts/route-* (not sure, maybe other files too)
/proc/*
/selinux/*
/sys/*
/dev/*
/tmp/*
/*lost+found/* (maybe)
/.auto*

If the partition Layout differs
/etc/fstab
and not lost+found for not existing file systems maybe.

Well, I done that years ago multiple times for one shot cloning not for 
regular Backups and i remember beeing surprised that it worked, its kinda 
hackish i believe. I am sure i forgot something important paths in list 
above.
