Those of us that act as DBAs or sysadmins for database systems know that DR is a point of emphasis for us. We usually spend plenty of time ensuring backups are working and practicing restores. The automated scripts and processes that people use are some of the most popular and discussed topics on SQLServerCentral.
However, we can’t ensure every system is protected at the same level. It’s not cost effective to cluster or build AGs with hot standbys, or even warm standbys, for many databases. Often our organization will ensure some are ready to go and others will have to be dealt with if there are issues.
William Durkin noticed recently that O’Reilly hadn’t prepared well enough for their learning site. They were affected by the fires and power outages in California and since they host some of their systems in an on-premises data center, there were issues. Certainly we might think they hadn’t prepared well for DR, and perhaps this is a fair view of their service, but perhaps they made the decision not to built out an expensive DR environment for a service that can tolerate some downtime.
This week, I wonder how some of you look at the systems you support. Perhaps you are the person that has to make decisions, or perhaps your organization doesn’t fund DR well. I’m wondering, how do you decide which systems don’t get enough DR support?
Certainly there are inexpensive, perhaps crafty ways that some people might plan for DR. I know I’ve cobbled together systems from spare parts to use for testing restores, with the idea that the hardware might need to be an emergency DR server for a single system or two in the event of an incident. If you’ve got ideas on how to be prepared even without organizational support, let us know today.
