[cobalt-users] Redundancy with two RaQs

["multivex" <multivex@xxxxxxxxxxxxxxx>]

As my web hosting business is growing, I am loosing sleep thinking in a
preventive setting to prevent downtime for the case of a crash in my RAQ
hard disk.

I understand that the RAQ domain and IP address is used as the first DNS
server for virtual sites.
So I point all domains in the server to this DNS,and it works fine

The problem is that I have the second DNS in the same RAQ, so if this device
crashes, I will have to face inmediate downtime for all the domains
contained in this server.

I am planning to co-locate a second RAQ with a different provider, in order
to have redundancy.

I will have four IPs in each RAQ,

So far so good. From here on, I am totally confused so I ask your kind help
to enlighten me::

Can somebody be so kind to explain how should I set the DNS servers for a
given domain so that the first DNS is in the first RAQ and the second DNS in
the second RAQ?

Where do I put the virtual site content for this domain? RAQ1? RAQ2? or BOTH
RAQs?
What happens with email? How does the RAQ2 gets content in the case of a
crash of RAQ1?
