True or False: An incremental backup always backs up more data than a differential backup.
Understand the Problem
The question asks about the difference between incremental and differential backups, specifically whether an incremental backup always backs up more data than a differential backup. Understanding the definitions of each type of backup is critical to answering this question.
Answer
False
The statement "An incremental backup always backs up more data than a differential backup" is false. Over time, differential backups can become larger than incremental backups because they include all changes since the last full backup, while incremental backups only include changes since the last backup (full or incremental).
Answer for screen readers
The statement "An incremental backup always backs up more data than a differential backup" is false. Over time, differential backups can become larger than incremental backups because they include all changes since the last full backup, while incremental backups only include changes since the last backup (full or incremental).
More Information
Differential backups accumulate changes from the last full backup, so their size grows over time, whereas incremental backups only save changes since the previous backup (either full or incremental).
Tips
A common mistake is assuming incremental backups always back up more data. Remember that differential backups include all changes since the last full backup, which can lead to them growing larger than incremental backups over time.
