What is the main purpose of system backup?

The main purpose of system backup is to prevent data loss. A system backup involves creating copies of data and system configurations that can be restored in case of unexpected events, such as hardware failures, accidental deletions, malicious attacks, or natural disasters. By having up-to-date backups, users and organizations can ensure continuity and recover critical data, minimizing potential downtime and the adverse impacts of data loss.

While options like increasing processing speed, upgrading functionality, and facilitating software installation are important aspects of system management, they do not directly relate to the primary objective of backups. Backups are specifically designed to safeguard against data loss by providing a recovery point for restoring information when needed.
