Thanks for replying.I actually would like to have the main server locally and the backup server hosted somewhere else with: Amazon, Godaddy, etc...
The cheapest way is to point the hostname to your home IP, and set a very short TTL, say 5 minutes.
Use the minimum your DNS hoster will accept.Then you can switch to your backup in that time frame by altering the A record.
This is trivially automated by running a cron script on the backup server that checks if your home IP is responding, and if not, switches the DNS record to itself.
