I agree with Mr Maniac, I also backup because in South Africa internet is paid per GB so we have bandwidth capping. So I use this to back up games bought from Steam that I may want to dust off and play again. I even cheated on race 07 because I have a friend who bought a physical copy of Race 07, and used that disk to install initially using my steam key.
I'm still struggling to convince my friend to install it again and play, he won't budge.
Speaking of Blobs, I recently discovered that I have the movie on my external, maybe I'll watch it soon.
