not mandatory but always recommended! It will update without erasing anything, but if you have any disturbance in the update (power outage....some type of hiccup) you could potentially lose everything!
It is really recommended to have a time machine disk always running!

I have a dedicated bay in my Mac Pro for time machine...it can be a life saver! I had an issue with my Boot Camp partition and in order to resolve it I had to reinstall everything, including Mac. I had that time machine partition....so from the time I inserted the disk to the time I was back to normal it took about 45 mins. Most of that time being install time...not setting anything up. Windows side of course took much longer, since there is no backup system in place.
1. If you have anything important on there you have to be backing up anyway. Your hard drive could ie at any time, your computer could be stolen, your battery could burst into flames.
2. Shutting down your computer in the middle of an OS install is a horrible idea. At 4 minutes left in a major OS install do you think shutting it down at that point is going to stop it from deleting your data if it was going to? It is finishing up by that point any damage would already have been done. Luckily Lion should not have deleted any of your files... hope it starts back up ok and you don't lose anything now.

I think the question contains the answer.
If you're not already backing up ever x minutes, than you've already consciously or unconsciously accepted that your data could be lost at any time - including while updating operating systems. So for you, the answer is no. Eventually, something terrible will happen, and the answer will be yes.

Not mandatory, but only prudent. Unfortunately, shutting down your Mac at four minutes minus Installation completion may have left your system corrupted or otherwise incomplete.
I'd recommend crossing your fingers, logging back in and if everything starts up- back up only your data (being *really* careful to copy everything you care about here. There may be stuff in places you haven't even realized) and perform a Clean Install at this point.
