A public-health reporting system requires an RTO measured in hours and an RPO measured in minutes. Leadership currently funds only nightly backups with restore from scratch. Which direction should the architect recommend?

Short Explanation
Nightly backups are a cold attic—fine if you can wait a day, rough if you need hours and near-fresh data. Pilot light keeps a small warm core ready so you are not rebuilding from zero. Match the DR pattern to the numbers, not the other way around.
Full Explanation
Disaster recovery strategy selection is driven by RPO and RTO. Backup-and-restore alone often cannot meet minute-level RPO and hour-level RTO because restore and rebuild take too long and last backups may be stale. A warmer pattern such as pilot light maintains core components ready to scale, reducing recovery time while keeping continuous or frequent replication for data. Weekly tape or single-Region backup-only designs do not satisfy those objectives.
