ITPEC FE Morning October 2020 Question 57
ITPEC FE Morning October 2020 — Question 57 of 80
When data is distributed across multiple files, backup should occur after all related update processes are completed to capture a consistent state.
- •This ensures the backup reflects a consistent snapshot — no partial or mid-transaction data
Why not others:
- (a) — ties full backup specifically to "the day operations commence" and limits subsequent backups to frequently updated data only; too narrow and not a general backup principle
- (c) — deleting both original and backup copies of low-use data defeats the purpose of backup (data preservation)
- (d) — overwriting on the same media risks losing both original and backup if the media fails; backups should use separate media
Key rule: Backup must capture a consistent state — wait until all related updates finish before backing up.
