CompTIA Server+ SK0-005 Practice Question
During a recent review of the nightly backup jobs, a systems administrator notices that the job scheduled for Saturday night takes substantially longer to complete than the jobs run Monday through Friday. After examining the configuration, the administrator confirms that Saturday's job is configured as a full backup, while the weekday jobs are incremental. Which of the following best explains why the Saturday job has the longest backup window?
The backup engine must merge every previous incremental set to produce a single recovery image.
The full backup uses block-level replication, which increases CPU contention more than file-level copying.
Open files on the server are locked, forcing the backup to wait for maintenance mode.
The job must read and copy the entire protected data set, causing the largest data transfer and storage consumption.
