As I listen to/read what is put by the various experts on here, I already have a back up of the important stuff. More than 1.
The e- mail back up is an interesting point. Every now and then I master it, and know what to do. Six months later when I ask myself how to do it, I have forgotten. Back to Google. As I know that I am weak on technology, (Sociology doesn't require any science at all, just an ability to argue) - I then decided to send myself a letter with my "know how" in it.
Er, you might spot the weakness in that plan..........
