What is a backup strategy and its test frequency?

• A. Regular backups (full/diff/incremental); test restoration periodically to verify data integrity and recovery ability.
• B. Backups should be performed only on a yearly basis.
• C. Backups are unnecessary if the system is replicating live data.
• D. Backups should run randomly without a schedule.

Answer: (A)

Backups need a real plan: regularly capturing data with different backup types and routinely verifying you can actually restore from them. A proper strategy uses full backups to snapshot everything, with differential backups to record changes since the last full, and incremental backups to capture changes since the last backup. Equally important is testing restoration on a schedule to confirm data integrity and that recovery procedures work, so you’re not surprised during a real incident. Without periodic tests, you might discover backups are corrupted, incomplete, or unusable when you need them. Yearly backups are far too infrequent, relying on live replication isn’t a substitute for backups, and running backups randomly without a schedule fails to provide reliable protection or predictable recovery.
