  "summary": "See what tightening your recovery objectives actually costs to build.",
  "description": "Recovery Point Objective (how much data you can afford to lose) and Recovery Time Objective (how long you can afford to be down) directly drive disaster recovery architecture cost, and the relationship is steep, not linear — going from daily backups to near-zero data loss can mean a 5-10x jump in infrastructure spend. This calculator maps common RPO/RTO tiers to a relative cost multiplier against a baseline backup-only DR posture, then applies that multiplier to your baseline monthly DR infrastructure cost, so you can see the cost of each tier before committing to an RPO/RTO target in a DR runbook or contract. It also computes the expected annual loss exposure at your chosen RPO — the amount of data or transaction volume you'd lose in a worst-case failure right before a scheduled backup — which is the number that should actually drive the RPO decision rather than picking a round number.",
  "formula": "DR cost = baseline monthly cost × tier multiplier. Exposure = transaction rate × RPO time window.",

    {
      "q": "How do I pick an RPO/RTO target instead of guessing?",
      "a": "Work backward from business impact: multiply your RPO exposure by revenue or transaction value per unit to get worst-case loss, and compare that to the cost delta between DR tiers from this calculator. If 15 minutes of transaction loss costs less than the jump from pilot-light to warm-standby architecture, backup-and-restore or pilot light is the economically correct choice, not a compromise."
    },
    {
      "q": "What's the practical difference between pilot light and warm standby?",
      "a": "Pilot light keeps only core infrastructure (databases, key config) running in the DR region at minimal scale, requiring you to scale up compute and app tiers during an actual failover, which takes anywhere from 10 minutes to a few hours. Warm standby runs a scaled-down but fully functional copy of the whole stack continuously, cutting failover to minutes but roughly doubling the always-on infrastructure cost versus pilot light."
    },
    {
      "q": "Is multi-region active/active ever worth the cost for a mid-size company?",
      "a": "Usually only when downtime cost per minute (see the incident cost calculator) is high enough that even a 5-10 minute RTO gap represents more money than the ongoing multiplier cost of running active/active. For most mid-size SaaS companies, warm standby is the practical ceiling; active/active is typically reserved for payments, trading, or infrastructure-provider-level businesses."
