Which procedure minimizes data loss by copying data to a separate storage medium?

• A. Defragmenting
• B. Backing up
• C. Encrypting
• D. Compressing

Answer: (B)

Backing up is the process of creating copies of important data and storing them on a separate storage medium or location. This provides a recoverable copy if the original data is lost or corrupted due to hardware failure, accidental deletion, malware, or disasters, thereby minimizing data loss. The other options serve different purposes: defragmenting reorganizes data on a disk to improve speed, encrypting protects data from unauthorized access, and compressing reduces file size. None of these create a separate, recoverable copy of your data, so they don’t directly minimize data loss in the way backing up does.
