How much data you can afford to lose. Example: RPO 5 minutes = backups/logs at least every 5 minutes.

Why backups are a different thing, how RPO and RTO drive every decision, point-in-time recovery, the 3-2-1 rule, the four DR strategies, and why an untested backup is only a hope.In System Design Case Studies 2
