ISPconfig on Debian Squeeze (Debian 6.0) with mirror server in different location

[Julian]

Hi
I want to install two servers like in this howto:
http://www.howtoforge.com/installing...th-ispconfig-3

only using ISPconfig on Debian Squeeze (Debian 6.0) with mirror server in different location.

My question is how can I do it so if the power goes down in one location to have the second server up in the second location.

Thank you very much.

PS: From I read on the forums that the GlusterFS its not so good. Do you think that its the best for what I need?

If the servers are in different locations, then you should consider to use unison instead of glusterfs to sync the directories.

Thank you Till for your answer, what about high availability when a server goes down?
Because I don't want to become another "Single Point Of Failure", I want to provide high-availability for the servers,
with the servers in different location with different ISP

You can write multiple dns records with different costs like:

mail.example.com 10
mail2.example.com 20

so if mail.example.com is not responding it takes the secound best choice.

On that server I have web, mail, dns, mysql! Not only the mail!
Something like heartbeat its not posibile?

You could look into pfSense and try to do the guide but for multisite configuration in some way:
