A company uses 'Incremental' backups daily and a 'Full' backup on Sundays. If the system crashes on Thursday, what is required to restore the data?

Answer options:

Only the Wednesday Incremental backup.

The Sunday Full backup plus the Wednesday Incremental backup.

The Sunday Full backup plus Monday, Tuesday, and Wednesday Incremental backups.

The Sunday Full backup plus the Wednesday Differential backup.

How to approach this question

Understand the chain rule for Incremental backups.

Full Answer

C.The Sunday Full backup plus Monday, Tuesday, and Wednesday Incremental backups.✓ Correct

The Sunday Full backup plus Monday, Tuesday, and Wednesday Incremental backups.

Incremental backups save data changed since the last backup (whether full or incremental). Restoration requires the last full backup and ALL subsequent incremental backups in order.

Common mistakes

Confusing Incremental (needs chain) with Differential (needs only last full + last differential).
