Use the right local data backup solution for your PC or Mac

Backing up your files is essential not only for preserving important photos and documents, but also for having recourse if your computer is ever attacked. On Windows 8 and 10, you can use File History to back up to an external hard drive over USB. In Windows 7, Windows Backup does mostly the same thing. In macOS, the built-in Time Machine is your best bet for local backup.
