LessThanDot Outage – Aug 22, 2013 to Sept 4, 2013

Over the past couple weeks you may have noticed that LessThanDot was completely down. I know we did. We’re working on solutions to our missing DR plan and shoring up some holes we found in our infrastructure (we had backups, they were just a little, er,…


SQL Server and High Availability

Realistically, 100% is unachievable given the nature of computing. There are needs for a SQL Server and Windows Server to be rebooted at least once a year. This is to allow for updates on both SQL Server and Windows to be maintained. So the ranking method we use for measuring high availability is the “nines” scale. The five nines is a goal that most database administrators and teams set for their standards. The five nines level is a height of availability that is truly an achievement and one to be proud of.


SQL University – Recess time!

The recess bell just rang for SQL University HA / DR classrooms. While all of the SQL kiddies are running around the playground and playing with the things they have learned over this semester, the chalkboard is going to get a workout so when they get back, they can take the notes they slacked on earlier.


Log Shipping for cheap DR

Welcome to day three of HA and DR week of SQL University. Today we are going to look at cheap DR. Yes, setting up DR can be inexpensive. The best part of this strategy is it comes along with most of the editions of SQL Server. The method is Log Shipping. Log shipping (LS) has a bad name in the Disaster / Recovery (DR) world. There are concerns with the ability to fail back to primary sites in the case of disasters, and LS is often thought of as a maintenance intense setup along with file mess. Today’s class will go over some methods to handle these and other concerns, along with the simplicity of configuring and monitoring LS in SQL Server 2008 (R2).


The SQL Server backup – foundation of any Disaster / Recovery

Welcome to our second class of HA and DR week of SQL University. Today we are going to focus on the concept, “Backups are for sissies!” OK, we’re really going to look at backup and restore for Disaster / Recovery (DR) and how being a sissy and always backing up our databases and testing out restores is a proven strategy for DR. When all else fails and the walls are falling down on the database servers, backups will be your life preserver. Backups are the foundation for Disaster and Recovery (DR). Backups can also save you when high Availability (HA) completely fails you. Let’s get started!
