Happy New Year! 

The January edition of TechNet Magazine is available on the web now and has the latest installment of my regular SQL Q&A column.

This month's topics are:

  • Using backups for corruption recovery
  • Why snapshot isolation is required when using change tracking, and its performance implications
  • Is DBCC CHECKDB a really comprehensive integrity check?
  • The difference between data file and log file shrinking
