Answer for screen readers
The final answer is that a differential backup covers data that has changed since the last full backup.
More Information
A differential backup is advantageous as it requires less storage space compared to a full backup while still ensuring all data changed since the last full backup is captured.
Tips
Common mistakes include confusing differential backups with incremental backups. Incremental backups only cover data changed since the last backup of any type, not just the last full backup.
