So, once I upgraded to a newer operating system, I never fully switched my external backups of my computer to that operating system. Bottom line is this: I want to do a complete backup of my computer, minus the music, to my external hard drives BUT I want to save the documents, music, pictures, and movies i have saved on my externals since not all that data is on my computer. What's the best way to do this? Attached is a screen grab of what my external looks like now. Should I just copy over the entire computer EXCEPT for documents, music, movies, and photos, leaving those things checked off in the list of what I'm copying (I use Carbon Copy Cloner)?
