It's really scary how quickly time flies – seems like it was just last week when I last blogged about TechNet Magazine (actually it was a month ago when I blogged about my 2008 Change Tracking article - see here). Anyway, a new issue of TechNet Magazine has just come out and this one has the latest installment of my bi-monthly SQL Q&A column.
This month's topics are:
How row-overflow columns can lead to poor range scan performance, even on completely defragmented indexes.
Combining database mirroring and failover clustering without undesired failover behavior.
Adding differential backups to a full+log backup strategy to lower recovery time.
Memory settings for multi-instance failover clustering
You can get to the column online at http://technet.microsoft.com/en-us/magazine/dd228989.aspx.
PS If you have any ideas for what would make a good SQL Q&A topic, please drop me a line – firstname.lastname@example.org
