ISC2 CC Practice Question: Business Continuity, Disaster Recovery, and Incident Response
A small business wants to minimize backup storage space and backup time, knowing that restoration may be slower. Which backup strategy should they choose?
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
✓
Incremental backup daily
Incremental backups capture only changes since the last backup (full or incremental), saving time and space, but restoration requires all incrementals since the last full backup.
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 weekly and incremental daily
Why it's wrong here
While this is common, the question asks for minimizing backup time and space; pure incremental daily would be even smaller but risky. However, the best answer here is incremental daily as it directly meets the criteria.
- ✗
Full backup daily
Why it's wrong here
Full backups are time and storage intensive.
- ✗
Differential backup daily
Why it's wrong here
Differential backups grow larger over time, taking more space than incremental.
- ✓
Incremental backup daily
Why this is correct
Incremental backups are fastest and smallest, but restore is slower.
