Test your backup strategy - pour wine into your computer

Don't try this at home.

I'm sure there is a branch of mathematics or psychology than can adequately explain why disastrous events seem to occur more frequently than you might expect. So - the toast will seemingly always fall buttered side down - into the cat litter tray - and the full glass of wine when knocked will always follow a perfect trajectory towards the laptop and deposit its entire contents into it. 

The latter is really, really vexing. I can tell you. 

So - four weeks later the replacement MacBook Pro arrived and I was wondering how long it would take me to restore all that software and data - some 100 Gb of it. All of it copy protected via various means - dongles - registration codes etc. 

So I switched the new Mac on. After the charming welcome video and choosing a language it said "Got any stuff you want putting on here from another Mac  - or Time Machine backup".
