I have a few named vhosts on my apache2 debian server and I want to have a mirror server that can pickup as soon as the first server goes down. We can assume I have total control over both servers and /www data on both servers is regularly and incrementally synchronized using rsync.
I can see ways of doing it at the DNS level, but I'd like to have a community input on that. Are there any solutions for achieving this out there already?
Thanks
