keep gauges values after statsd server restart

Hi, I'm in loved in statsd protocol simplicity. I'm using statsd gauges + graphite + grafana to meter rising values, where I have acces only to delta. But there is a problem for me. When statsd server restarts, i'm loosing gagues values, where I would like to keep them for a long time (month at least). Of course I know that statsd is not dedicated to use in this way, but... Is there a way to preserve gaguses values during statsd server restart?

Best regards!
