Backup and Recovery and Failure

“There is not a question of if a hard drive will fail. The question is ‘When?'” — Philadelphia Area Computer Society (PACS)

I was doing really well with my projects on an Ubuntu 18.04 desktop until the system crashed. I think that my version of Ubuntu had some problems with memory management. Of course, any time one open 20 browser tabs, one is going to run out of memory! Power user? or slob? A friend of mine had a similar problem with audio buffer overruns on Ubuntu .

I think that some other operating systems might fail a little more gracefully. At any rate, any time one forcibly shuts down a running computer system there is a possibility of data corruption. We have to be ready for that contingency and ready to restore the hardware and operating system and files of the computer to the state they were in within a reasonable amount of time. That is the Recovery Point Objective and Recovery Time Objective.

I had everything working on this system! And it was my fun task to continue to configure the computer. Now I am starting over again. This is not easy without a “roadmap” of steps to take to recover and build a computer system. That is why I am writing this blog post.

The computer had Samba and GTK+ the graphics toolkit and Wireshark all running and configured. Also the ‘alsa’ sound system was working great! There were however no personal files of any importance to restore. Change “Backup and Recovery” to just “Recovery” please!
