Secondary ISPConfig server

[Captain]

Hello!

I need to know. It is possible to create a second server based on Ubuntu 9.10 with ISPConfig 2 as secondary server with another public IP.
Idea is:
Now I have one web hosting server on Ubuntu 9.10 ISPConfig 2. And I want to create a second server as a recovery or secondary server. For expl. if the first server is down all my clients can use my secondary server.

It is possible to create and how I can to do this?

Big thnks.

It's not that easy because you need a virtual IP that "floats" between the nodes. I think you can do it if you use something like HAProxy: http://www.howtoforge.com/setting-up-a-high-availability-load-balancer-with-haproxy-heartbeat-on-debian-lenny

OK. But how I can clone my web server. For expl. I have ISPConfig with ubuntu 9.10 and I have another server with ubuntu 9.10. And I want to mirror my primary web server with ISPConfig to my secondary. After that I have two servers with the same systems and configurations. How I can to do this? DRBD? But how to correctly clone my server without interraptions and errors, because my primary server have apr. 20 clients.

Thnks!

I'd use rsync and MySQL replication.
