need advice on sync between computers
i have a computer at work running debian that acts as a server and more.
we have a backup computer too. Now, its really bad for our server to go down for more than an hour or so, so i was wondering...
is there a way to set up the back-up computer to have a copy of all the info on the main box (mysql database, server-stuff, etc...)
i could even write something maybe in python (the only one i am comfortable with right now) to keep them going.
is there a way, since both are on the same network, for one box to know if the other has dropped off line so it can take over as the server (means changing its internal ip address so it can get past the router, etc.)
any advice or apps out there that you know of for this kind of thing would really be a pointer for me, i am kinda new at this.
