setup a site mirror

Hello ppl,

since a while I'm thinking on creating a miror for my site , but I don't know exactly what I should do, I have some question for you.

#1 About the nameserver, if I set my primary nameserver ns.host1.com and secondary nameserver ns.host2.com :

when host1.com will be offline (hope never) all the request to my site are sent to secondary nameserver , host2.com ????

if an user is geographic closer to host2.com will be automatcly sent to that miror(host2.com) or will see the site from host1.com ?
geographic closer I mean if the user is from europe,
the mirror is in europe too and the main site is in the USA .

#2 is there some tool to make an automatic update of the mirror, files and database (MySQL) ??? or I should create a script which will compare the directories of the mirror with the main site , and for database the same thing something to compare bouth databses. ???

any help will be apreciated

10x in advance

see ya all

#1) Randomly
#2) Just to name a few: rsync, cvs, and mod_proxy in Apache

As for the ns1 and ns2 where one is offline...

As freebsd said, the server that is used to resolve a request for your domain is chosen randomly. Now, resolvers SHOULD try the next server if the one it chose failed. So, theoretically your domain will continue to resolve just fine if one of the servers is down. However, there have been times in the past where a website domain didn't resolve and I checked out the DNS to see why and found that 2 of 3 dns servers were down for that domain, but I could still resolve with the one remaining - but only "manually".

So I strongly recommend that you do NOT include tricky dns servers as authoritative for domains that are not tolerant to downtime.

#2 -> can you give me more details pls or some documentation about miroring ... I searced the net but i found nothing

Tell us what exact search keyword did you use. Or simple enough, just do it yourself by using the combine search keywords rsync cvs mod_proxy mirroring at google.
