Higher frequency snapshots/replication

[dniq]

I'd like to make the delay between the data being updated on the "Master" server and it being replicated over to the Replicas as short as reasonably possible. Ideally it'd be "instantaneous", but since FreeNAS doesn't seem to support real-time replication - 5 minute intervals would be OK. The GUI only allows to set the shortest interval to 15 minutes. Is there a way to change this interval from console somehow? Doesn't look like it's in root's crontab...

Would really appreciate any help on this!

Thanks!
