I have a small internal web server that I want to mirror for backup reasons. I would like to have it such that if one computer goes down the other will take it's place seamlessly.
In other words:
As "raid 1" is to drives...
$solution is to websites.
I am looking for a raid 1 type solution for websites (if it even exists).
I know I have a few tools such as rsync and MySql slave master database redundancy, but it seems there are still a lot of holes in the process such as keeping each distribution instance equally up to date.
I am also looking to do this with free software. The server is CentOS4.
I am sure others have run into this and would appreciate any input.
