I have an RB1000 and RB450G as a hotstandby.
The RB450G has an IP Address in the range allocated which is different to the RB1000. Should the RB1000 fail then the RB450G can take over with the change of a couple IP's. I need to replicate the firewall rules from the 1000 to 450 when ever rules are changed. I will be happy even with a manual export/import. I tried searching the forum/Google for this and never found anything useful. We currently have ver 4.3 on the live units. I know there are newer builds than 4.3, but I can't have a firmware upgrade maintenance for a few weeks.
