WordPress MU

I'm new to wordpress mu and already in need of a backup solution.. It seems these blogs are more prone to 'attention' than some of the other lesser known systems.

I'm looking for a way to replicate the wordpress MU setup onto another server (from another host company) so that I can have an active domain monitoring dns service switch over to the backup should the primary one stop responding.

Can you point me to a good resource guide on how to get this done, and the best way to do it given the single-database structure of wordpress mu. On a side note, I've noticed that wpmu seems to be locking files (ex .htaccess) so I hope that all of the flat files can be moved by simple rsync/sftp..

Suggestions? Ideas? How do you backup?

I would setup RoboCopy to run for the file migration and then you should be able to automate database sync with tools specific to that.

I would not recommend trying to tie the replication into the site as this creates a vulnerability in your process.

In point, I'd do it all serverside with triggers, checks and stops.
