It is hard to do so with AMQP. If your server with carbon caches dies it will loose all datapoints which was still reside in memory and not yet flushed to disk (on SSD is not that critical - but you can loose 1-2 minutes of datapoints). You can setup cluster with another tier of relays, which will have REPLICATION_FACTOR=2 and will distribute your load across 2 (better 3) backends - but if one of your nodes experienced downtime - you need to proper sync up whisper files across nodes before enabling it - otherwise you will have gap in graphs too.
