However, I have setup multiple redundant location separated geographically. I setup IPSEC VPN between firewalls to make the AD sync its DB and also use MS Sync Toy to copy other apps data from PR Server to DR Server, script for X server. So when the PR is hit by a missile, hopefully I wasn't there, I can just make the SLAVE DNS in DR as MASTER and change the record to point to DR and voila it's up.

For server with big DB, need an off-site backup to send to remote site or better yet (if you can afford) get a higher bandwidth pipe between sites to sync DB.
