Hey guys, I'm thinking about making a redundant fail over cluster of my servers. I was thinking either doing a round robin dns with rsync to duplicate the servers or do something from the linux virtual server site. Anyways, with that in mind. Should I have rsync duplicate the entire drive? (Which I think will take forever) or should I have it sync just certain folders. And if so, which folders are key for ISPConfig to function? Thanks for everything you guys do. It is greatly appreciated.
