As you may know, I've been teaching the SQL Server portion of the SharePoint MCM since it started. The old database maintenance whitepaper for SharePoint 2007 had all kinds of things wrong with it and the publishing of the updated whitepaper for SharePoint 2010 was eagerly awaited by the community. Unfortunately it too had a bunch of problems so I offered to get involved and comprehensively review and rewrite it, and did so just before the summer.

It's finally been republished with all my revisions and you can download it from: http://technet.microsoft.com/en-us/library/cc262731.aspx

Enjoy!
