Sooooo. I'm eventually at the point where I have enough large games in my Steam Library, that I don't want to keep them on my drive at all times, but I don't want to wait hours for them to download whenever I feel like playing them.

The integrated back-up seems slick enough, but I'm wondering whether it would be worth going through Steam's alternate procedure, using 7-zip to compress the game files instead of simply copying them over.

Any experiences you'd like to share?
