Ok here is the situation.
I have an existing Linux box up and running. I cannot do anything to disruptive to it. It runs our mail and connectivity to the world. My question is. Is there a way to make a standby server with all files and everything I need almost like a clone, so that if something happend to server a ...can just plug in server b?
I have checked into rsync ...but from everything I have read about it, it does not like files that are locked or DB files.
Both box's are differnet hardware configs
Also I am open to the possablity of comerical products.
