Question 7

What is the fundamental difference between full and differential backups?

Accepted Answer

Full backup copies all data, while differential backup only copies data that has changed since the last full backup

Answer

Full backup copies all data, while differential backup only copies data that has changed since the last incremental backup

Answer

Differential backup copies all data, while full backup only copies data that has changed since the last incremental backup

Answer

Full backup only copies changed data, while differential backup copies all data

Question 8

What is a key difference between traditional data backup and cloud-based data backup?
