How to backup data

Recently I wrote about my experiences of upgrading my computer at home.  Unfortunately I ran into some issues and I had to restore all my data from a backup.  After a few more issues I managed to get all my data back.

I have created a brief presentation outlining how I protect my personal data at home.  In the presentation I describe the tools and procedures I use to protect my personal and working data from hardware failure or loss. This exclusive presentation for Tech Faculty subscribers can be found here..
