The amount of cpu consumed in any asterisk system is the sum of all the 
activities in "your" system, not someone else's. G729 codec cpu 
consumption only occurs if your system requires translation from another 
codec to G729 for calls or playing sounds. All g729 calls from a g729 
device to another g729 device operate in a pass-through mode, and do not 
consume codec translation cycles.

There are several good references on the wiki relative to this as well 
as cpu sizing, etc. Take a look.

The digium g729 codec lives in /usr/lib/asterisk/modules (on a fc3 box) 
and will be backed up "if" you config your backup appropriately. Not 
sure what needs to be backed up for the license part of their codec 
since the license is based on the mac address of your nic card. Someone 
else will need to comment on that. (Its fairly easy to re-license it 
with digium anyway.)
