I've just been itching to post this one.
I'm doing a chalk-talk (AKA cabana session, this year AKA Technical Learning Centre session) at TechEd next Wednesday (8.30am 6/14) called 'DBCC CHECKDB: Magic, Monsters, and Myths'. A lot of the material in this will be included in the mega-whitepaper on DBCC I'll be writing over the summer, but it also slices nicely into blog-size posts so I'm going to do a series of them over the next month or two covering everything from today's topic to very deep drilldowns into how specific repairs work. If there's anything specific you'd like to see, let me know.
Billy Connolly (a great Scottish comedian) tells a story from his childhood about his father listening to the radio at breakfast while eating his outmeal, and every so often shouting 'No!!!' at the radio. Eventually the radio had a nice spackling of dried outmeal. I usually read the newsgroups and various MS and non-MS forums every day or so - and if I were to read them at breakfast, my laptop screen would very quickly get a nice spackling too (not of oatmeal though - nasty stuff).
I really despair to see some of the 'advice' that's out there, even though its all well-intentioned. Here are some of the gems related to disaster recovery - and I'll try not to rant.
"Just run REPAIR_ALLOW_DATA_LOSS and you'll be fine..."
"Just rebuild your transaction log using these steps..."
"Just restore your database and carry on..."
"Run CHECKALLOC, then CHECKDB, then CHECKTABLE on all your tables, then..."
"Just flick the power switch on and off a few times on one of the drives..."
These are the worst ones around disaster recovery. I could go on all day about not shrinking database and not blindly rebuilding all indexes every night but it's lunchtime so I won't go there - yet :-)
