Mirroring 101 - how can I set up a website mirror?

[coopersita]

Hi all,

I have a friend who has a blog, and some paranoia. He's afraid someone will attack his blog, and wants a mirror so his blog will be up despite that fact.

I've never done anything like that, but if the site is actually attacked, wouldn't the mirror be affected as well? Aren't mirrors more for load and bandwidth management?

Thanks

The answer depends on the complexity of the blog and the depth of his pockets - if you have a constantly-changing database (new articles, comments, etc...) then the challenge is harder than for a static site which can simply be mirrored across multiple servers.
