ISC2 CC Practice Question: Business Continuity, Disaster Recovery, and Incident Response
An organization is choosing a backup strategy to minimize restore time. Which TWO backup types require only the most recent full backup and the latest differential backup to restore?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Full backup
To restore using only the most recent full backup and the latest differential backup, both a full backup and a differential backup are required. The differential backup captures all changes since the last full backup, so restoring the full backup followed by the latest differential provides the complete data. Therefore, the correct answer is full and differential.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Full backup
Why this is correct
A full backup is the base. It must be restored first before applying any differential backup.
- ✗
Synthetic full backup
Why it's wrong here
A synthetic full backup is not a real full backup but a construct; it does not change the backup chain. The restore still requires a full backup and a differential.
- ✗
Incremental backup
Why it's wrong here
Incremental backups require all backups since the last full to restore, not just the latest differential.
- ✗
Reverse incremental backup
Why it's wrong here
Reverse incremental backups create a full backup and then only store deltas; restore requires the full backup and reverse incrementals.
- ✓
Differential backup
Why this is correct
The latest differential backup contains all changes since the last full, so it can be applied directly on top of the full backup.
