HT1427: Mac Basics: Time Machine backs up your Mac

Learn about Mac Basics: Time Machine backs up your Mac

HT1427 I have a brother who is paranoid. He is starting to use an external hard drive to back up his information on his Mac. He says he is afraid that this might erase information from his computer hard drive. What can I tell him to allay his fears?

I told him "The information only goes in one direction: from your computer on to the external hard drive. Like water coming out of a faucet. It doesn't go back in." But that's not very technical. I need a technical answer to satisfy his worried mind!  Thanks!
