ITPEC IP April 2021 Question 22
ITPEC IP April 2021 — Question 22 of 100
Restoration to Tuesday closing requires Sunday's full backup followed by Monday's and Tuesday's incremental backups. The full backup establishes the complete base. Monday's incremental contains changes since Sunday, and Tuesday's contains only changes since Monday, so both increments must be applied in chronological order.
Answer (a)
Why not others:
- Tuesday's incremental does not contain Monday's changes
- incremental files alone lack the full base data
- omitting either the full backup or Monday's increment leaves the restored state incomplete
Key rule: Restore an incremental-backup chain using the last full backup plus every subsequent increment through the target time.
