Sys Admin Disaster Recovery

I have recently been tasked with creating a proposal outlining different disaster recovery options which we can offer to clients.

The more I started to think abut this the more I realised that as a fairly novice sys admin I knew very little of the problems that can occur and the disasters that can happen.

I began to research this. I read a few blogs to begin with. One of the first that I read (http://www.simple-talk.com/sysadmin/general/unteachable-disaster-recovery-techniques/) was quite interesting. It basically outlined that while best practices and knowledge of a system will help, certain aspects of avoiding disasters comes from intuition and experience.

It seems that to quote a comment on another blog, I will need to walk the minefield to gain this experience.

http://forums.theregister.co.uk/forum/2/2011/06/14/sysadmin_it_disasters/. This article outlined the top ten sys admin disasters. What was interesting was reading some of the comments. This has helped me gain a bit of understanding into what can go wrong.

While a lot of the problems were explained by onsite (data centre) hiccups (Plugs being unplugged or emergency cut off switches located next to light switches without a protective cover) a lot of the time it was people not taking care of the backup procedure correctly.
