Gnu wget can be used for mirroring web sites. It's not the fanciest, but
the price is right (free :-). Have a look at

I look forward to reading your summary, because I want to do the same
thing myself. I've found 1 possible solution, but I haven't played with it
yet. (mirrors themselves)

Hi Micah
This is quite a good one, as there are a number of ways this is done (complete or
sort of!).
First:
Two workstations as first, but each poles for the other one, and
should the other one die, the second server reboots, 'faking' the first
server, (this has complications when you have routers that hold
the MAC address for long amounts of time (normally configurable).
Because the MAC address will not match the IP address. Information on
the web site is backed up nightly to the second web server.
Second:
Two workstations running alongside each other, with their own names
and IP addresses, with a DNS round robin for both hosts. I.e. the
DNS entry www.domain has two CNAMES of www1.domain and www2.domain.
If you upload a file to one web-site, then you upload it to the other
at the same time. If one of the web servers goes down, at least you
have half a service.
Third and best:
Two workstations, with Fibre Channel connections to a central storage
array, where all software (web and applications) are run from. Veritas
software installed on both servers, and configure the veritas software
to provide polling of processes, if one process on one host fails, the
process starts up on the other host. BUT COSTLY!
I have opted for the second, as I have datafeeds going directly to the
web servers updating them every few seconds.
