  • Ola Hallengrens Maintenance Solution now supports mirrored backup

    You probably know that you can mirror a backup to several destinations, assuming you are on a supported edition (Enterprise or Developer). This is not the same as striping; you can compare striping to RAID 0, and mirroring to RAID 1. Ola now supports mirroring in his maintenance solution, found here. A couple of examples: EXECUTE ...

  • How often do you rebuild your heaps?

    Never? You are not alone. None of the maintenance solutions I use includes functionality to rebuild a heap, and that includes Maintanance Plans and Ola Hallengren's maintenance solution. ''So why would you want to rebuild a heap, when it isn't sorted in the first place?'', you ask. The answer is to get rid of Forwarding Pointers, and these can ...

  • October Update to Rules-Driven Maintenance

    Happy Fall! It’s a beautiful October here in Minneapolis / Saint Paul. In preparation for my home town SQL Saturday this weekend, as well as the PASS Summit, I offer an update to the Rules-Driven Maintenance code I originally published back in August 2012. It’s hard to believe this thing is now more than two years old – it’s been an incredible ...

  • Stats on Stats

    I have been working on new features for the Rules-Driven Maintenance Solution, including per-index maintenance preferences and more selective processing for statistics. SQL Server stats is a topic I knew about at a high level, but lately I have had to take a deeper dive into the DMVs and system views and wrap my head around things like ...

  • March Update to Rules-Driven Maintenance

    This month I have a minor update to the Rules-Driven Maintenance code I originally posted back in August 2012. This update has just two enhancements, but they are nice ones, I think: Much improved handling for instances that use database snapshots. Ability to do intra-day differential backups purely by setting maintenance times and limits ...

  • Visualizing Data File Layout II

    Part 2 of a blog series visually demonstrating the layout of objects on data pages in SQL Server Part 1 In Part 1 of this series, I introduced a little demo app that renders the layout of pages in SQL Server files by object. Today I’ll put that app through its paces to show, in vivid color (well, teal, anyway) the destructive power of the famous ...

  • Visualizing Data File Layout I

    Part 1 of a blog series visually demonstrating the layout of objects on data pages in SQL Server Some years ago a gentleman called Danny Gould created a free tool called Internals Viewer for SQL Server. I’m a visual sort of guy, and I always thought it would be fun and educational to make a simple visualizer, like the one he created, in order to ...

  • Update to Rules-Driven Maintenance

    Back in August I posted a first version of a rules-driven solution for backups, index and statistics maintenance and integrity checks. The system in general has been working well, and has saved my team a huge amount of time and effort. We are coming to the anniversary of its use in production soon. Today I offer an update that contains a few ...

  • Backup File Naming Convention

    I have been asked this many times before and again just recently so I figured why not blog about it. None of this information outlined here is rocket science or even new but it is an area that I don’t think people put enough thought into before implementing.  Sure everyone choses some format but it often doesn’t go far enough in my opinion ...
