Question:

A site follows grandfather-father-son rotation: a full backup every Sunday and incremental backups Monday through Saturday. To restore the system state as of Wednesday evening, which backup sets are required? / साइट grandfather-father-son रोटेशन अपनाती है: हर रविवार पूर्ण बैकअप और सोम-शनि वृद्धिशील बैकअप। बुधवार शाम की स्थिति बहाल करने के लिए कौन-से बैकअप सेट चाहिए?

1.
Wednesday's incremental backup alone
2.
All incrementals from Monday to Saturday plus the previous month's full backup
3.
Sunday's full backup plus the Monday, Tuesday and Wednesday incremental backups
4.
Sunday's full backup plus only Wednesday's incremental backup

Correct Answer: Sunday's full backup plus the Monday, Tuesday and Wednesday incremental backups

Each incremental holds only changes since the previous backup, so the full plus every incremental in the chain up to Wednesday is needed to replay the week. / हर incremental सिर्फ पिछले बैकअप के बाद के बदलाव रखता है, इसलिए पूर्ण बैकअप के साथ बुधवार तक की पूरी शृंखला चाहिए। Option (d) is the trap — it confuses incremental with differential backups.
