The March 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:

  • Distributed transactions and database mirroring – why they don't work together
  • Background processes that can cause I/Os even with no connections to the server
  • How to restore backups from a file containing multiple appended backups
  • The perennial problem of production databases being too large to restore in development
