I've just unticked the top three though. All I want to save are the two folders below them. I assume that unticking the top three won't matter?
One other thing. This is something that happens with my Intenso external hard drive anyhow. If you want to replace an old folder saved on it with an updated file (same file name) saved on the desktop, you FIRST have to delete the old version of the folder from there (the Intenso external drive). Then you copy and past into it the update taken from the desktop. If you leave the old version on Intenso, you can't replace it with an updated version from desktop. (You might think you have, but when you check, the old version is still there on Intenso.) Not sure if this is going to be a problem with this automatic update and backup facility we're talking of.
