Backing up is defined as:

Backing up is defined as:

• A. Making copies of data and storing the copies in a different place from where the computer is kept to prevent data loss
• B. Saving data to the same drive
• C. Deleting duplicates
• D. Encrypting data only

Answer: (A)

Backing up means making extra copies of important files and storing them somewhere other than your main computer so you can recover them if something goes wrong, like hardware failure, accidental deletion, or a cyberattack. That exact idea—creating copies and placing them in a different location to prevent data loss—is what backup is all about. Keeping data on the same drive doesn’t protect you if that drive fails, and deleting duplicates or encrypting data by itself doesn’t give you a recoverable copy. In practice, it’s common to follow a rule like: three copies of data, on two different media, with at least one copy kept off-site.
