SSCP Security Operations and Administration Practice Question
Which backup type copies all data that has changed since the last full backup, regardless of any incremental backups?
⚠ Common exam trap
Test-takers frequently confuse differential backups with incremental backups, but the key differentiator is the reference point: differential backs up all changes since the last full backup, while incremental backs up changes since the last backup of any type.

Correct answer & explanation
✓
Differential backup
A differential backup copies all data that has changed since the last full backup, regardless of any intermediate incremental backups. This means each differential backup grows in size as it accumulates all changes made after the last full backup, making it distinct from incremental backups which only capture changes since the last backup of any type.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Synthetic full backup
Why it's wrong here
Synthetic full combines full and incrementals, but is not the definition above.
- ✗
Full backup
Why it's wrong here
Full backup copies everything, not just changes.
- ✓
Differential backup
Why this is correct
Correct. Differential copies changes since last full backup.
- ✗
Incremental backup
Why it's wrong here
Incremental copies changes since last backup (any type).
