When you think it won't happen to you, it happens. I was just talking to my boss about backups and how important they are. Guess what, I didn't had a recent backup when my HDD died last week. I couldn't gather the data in it, had to send them to them "recovery experts" since the contents of the HDD is irrecognizable, with a bunch of meanless dates (like 01-01-1915) and filenames as [~´rgcs~er´t~saér, and of course, wouldn't boot to Windows.
If you have work done, and you praise for your data, backup... I feel like a dumbass now, but I had to expose it somehow.
Now the good thing is, I HAVE a backup of NR sources, and it's intact and recent, I'm just using a really low end computer right now, that got windows 98 and 64MB of RAM, using internet explorer 4. Isn't it beautiful? No work until I get my data back, and my new HD and system build (it was about time).
