Centralised mysql and rrd via NFS would be easier and lower bandwidth. Observium was originally built with this possibility in mind, though we rarely push it.

Syncing rrds is a terrible idea, look at the size of your rrd folder :)

Well I guess the hard part would be to have a distributed database?

I have no experience in DB-clusters but if you could have a MySQL-server in each region that syncs with each other active/active-style (no idea if that is possible considering the delay)

then it should not be to hard to just have a rsync-job syncing the RRD-folders(does not need to sync every 5min, the data will still be there) and modify the poller-wrapper to instead of launching poller.php instances locally make it launch them on remote servers.

maybe.
