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.)
