WordPress MU

I have a installation running on the following configuration

WP-MU installed onto a VPS server running CentOS
Nightly dumps of the Database to the File system
Nightly backups of the file system including all system configuration files mu files and blog dirs. to Jungle disk.

At the moment if one of my clients manages to wipe out his blog I am looking at doing a total recovery of my backed up MU to a secondary location so that I can do an export of the clients single blog. is there a plugin out there that can be scheduled to run the export function tin the Tools menu and either place it in the file system somewhere or email it.

Any suggestions or Ideas would be greatly appreciated

You've already got the entire database, just grab his blog-specific tables from the dump and restore them to your live db.

The internal export is actually a bit more intensive. why fire up WP just to do more backups?
