Dear Daniël, I am behind the keyboard since 1974 and can assure you that ANY methode you choose or how much money you would spend for it to keep backups safe will eventually explode in your face. My advise which I can give to RIPE is as follows: NEVER, EVER run a primary DB (DNS/rDNS) server out in the open. Always run a primary DNS server on private IP's, use NAT translation towards selected public secondary DNS server which do the actual advertising for you. NEVER, EVER trust one single OS to run DNS. If you use the method above, it is possible to pick up the zones on different platforms. (Even mainframes like IBM/TPF could be included also) Bind/SQL DB: reconstruct your DB from source files every 24 hours. Bring the original down for 1 second and swap the names of the live DB with the rebuilded DB. This methode comes directly from airlines which evidently run the biggest DB's worldwide... You could even run integrity checks before you publish the new DB. Hope it helps...
