Creating a backup of your programs and files protects against the unexpected loss of files. Backups can be as easy as making a copy of your most important files and saving them on a flash drive or external hard drive that you store somewhere safe. For more complete protection, you can back up your entire system by creating an image of the hard drive on a separate storage device (usually an external hard drive, network-storage device, or a cloud storage service). Once the image copy has been made, then incremental backups can then be run periodically (usually daily) to ensure that changes to the system are backed up so the backup copy is always up to date.
