How can I mirror two hard drives in two different machines?

Here is my situation,

I am running two identical boxes with the same configuration and
partitions.  I have two nics in each box and I have a cross over cable
between the boxes so that they can talk to each other directly.  These
are mail servers and one is live and the other is backup.  Now the
question.  Two partitions will be constanly be changing, /home and
/var because of the email.  How do I make the primary server write to
both /home and /var on both servers?  I want the data to match on both
servers, in case the primary fails, I can change the IP address of the
backup and continue serving mail.  In essence, how do I mirror these
two partitions to another box?

Thank you

1. How to trigger two programs on two different machines at the same time?

Hi all,

I hope this is a proper ng to pose my question, could you please point
me to a better one if otherwise?

I need to run two different recording systems each residing in a
separate machine: one acquires audio while the other records video.
Obviously, I want the two resulting streams to be as synchronized as
possible, i.e., they should start recording at the same time.

How good do you think it would be to do this over the ethernet network?
Also, could you suggest a way to program a script that would launch the
recording on the second machine at the same time as the one on the first
machine? Any pointer on where to start studying in order to achieve this?

Thanks in advance for any hints you'll give me.
