server fallback
two servers, server1 running plesk and all the domains/webhosting and server2 being the backup for it, when server1 is down server2 has to take over everything.
I was thinking on making a script which makes a backup every 24 hours or less (depends on this customer), if server1 is down server2 will take over the ip and everything should be running nice, with content which is at most 24 hours old.
But I thought that maybe a loadbalancer (either hardware or software) would be good for this two, can somebody explain me if this would work and if the content on both servers will be the same using a load balancer.
And in the end, if a load balancer would work, what do you guys advise me to do? get a hardware load balancer (and which one) or create a software load balancer (with software like www.linuxvirtualserver.org or something like that)
BTW, the customer only wants this, the netwerk is already redunant (we're connected with 5 connections, 4 transit, spread over two routers) and locate two servers at two different locations isn't an option
