Question

Quizplus · Accepted Answer

Incremental backup is a type of backup that only backs up the blocks that have changed since the last backup was performed. This helps to save time and storage space as only changes need to be backed up rather than the entire system. DNS and secondary DNS zone are not related to backup types, and a full backup would backup the entire system regardless of changes.
