You should either:
- replicate the packets at radius level, and have each radius write (both
packets that it received directly and the forward packets) to its own db. OR
- use active-active db replication (e.g. galera)

Depends on your need. robust-proxy-accounting should work, but on some
setup it might end up filling the disk (e.g. when bad home server rejects
Personally I prefer rlm_replicate, which is very fast but might lose some
accounting packets due to it's send-and-forget menchanism (I'm fine with
