Freeradius 2.1-1: failure modes

I want to keep NAS table replicated in redundant SQL servers for failover
reasons, is this fair?
Now, if NAS is kept only in one SQL server this will become a single point
of failure and if this particular DB fails then radius application cannot
just seemlessly failover to another redundant DB server because NAS table
can exist only on one DB server because of freeradius design/limitation.
How do you propose solving SQL NAS table replication challenge?
I understand that you can tell me keeping NAS info in local flat
file(clients.conf) and do not reply on database.
Then I'll need scripting on every radius server periodically connecting to
DB and generating NAS (clients.conf) on the fly and HUP the radiusd or do
not rely on database and hand edit clients.conf file and rsync it.
But it would be nice to keep NAS information in DB but also have sql
Thanks again for you reply.
