What happens if your computer crashes?
Some people will even say:
What happens WHEN your computer crashes?
Because it's really a question of luck and time.
My luck run out at very bad timing. I was spending some time with my family in Portugal (my country of birth) and was not expecting that my computer would let me down.
The good news was that I have a good backup of my data (thanks to Time Machine and an external drive).
The bad news was that the external drive with the backup was in Phoenix, AZ and I was in Portugal, Europe.
Here are some of the lessons I learned from this experience.
