Re: How the SQL Server World Lives



fixed

Jim,

I think you've got it backward...

I don't believe it even possible for a SAVE to damage an object. But a
damaged object is often detected during the SAVE operation.

The question of if a damaged object is considered a corrupted file then
yes, I have seen it. Usually it's as the result of a Save/Restore
operation that failed, but it does happen.

A recent article, "My SQL Server Database is Corrupt - Now What?!", had
some
interesting statements from the author:



. I was asked how often corruption really occurs in the real
world.
My answer was, "hundreds to thousands of times every week across the
world,
in the tens of millions of SQL Server databases.".

. Every single week I receive multiple emails asking for some
advice
about corruption recovery. When I'm teaching about corruption in our High
Availability and Disaster Recovery Immersion Event, I always tell the
class
that I expect every DBA to see database corruption at some point during
their career.

. I'll end by saying this: if you think that corruption won't
happen
to you at some point in your career, I think you'll be surprised. Be
prepared!



I'm curious.. How many of you have seen corruption on our platform? In
25+
years on S/38, AS/400, and IBM-i, I have NEVER had an issue with corrupt
files/tables. In 1 year of SQL Server at my former employer, I saw it
happen at least 3 times. I was shocked but the Microsoft bigots in the
company just shook it off as status quo.



Here's the article but you have to be a member to read it.
