I just don't get it. Maybe I just don't know enough about it, but I tried backing up my MacBook a couple times and I started thinking...this sucks for backing up and archiving. If I'm looking for a certain picture in iPhoto, I would have to go through back up after backup just to find it. Wouldn't it be easier to drag and drop into a certain folder and save that externally to a hard drive? Or is backing up with time machine primarily used for apps and app data? I'm...confused. I need to be enlightened! What is time machine good for? Why is using it better than simply dragging and dropping stuff into folders?
