Backing up files helps you prevent the loss of important documents, applications, and other software.
You should back up important documents every day by copying the files to another disk (such as a floppy or Zip disk, a shared disk on a network, or an external hard disk).
You should also use a backup application to automatically back up the entire contents of your hard disk.
