Explanation

The renice command changes the scheduling priority of a running process. By using renice -n 15, the administrator lowers the priority of the backup process, making it less CPU-intensive and reducing its impact on other system services. A positive niceness value (e.g., 15) lowers the priority, allowing other processes to receive more CPU time.
