Question 9 • NC-Foundations of Information Technology
Network backups create copies of data that can be restored if a network or its storage fails, so they help protect against failure. They are commonly scheduled at night, when fewer people are using the network and backups are less likely to disrupt work. Therefore, “Network backups help secure networks against failure” and “Network backups are usually done nightly” are correct; they do take users’ needs into account and are not usually done during the day.
