Tristen from Cincinnati, OH

Tristen wants to know how to backup his computer so that he has a copy locally. Leo says in the old days, we would divide backup into online, nearline, and offline backups. Online backup would be a hard drive connected to the computer that is synchronizing with data directories. So he'd have a copy on the computer and on the external drive. Nearline backup would be if the drive were put up on a shelf, and disconnected from the computer. Offline backup would be off in the cloud or at a different location entirely. It's best to use all three methods and keep multiple copies.
