Database Backup & Restore Strategy — Tested Restores or It Didn't Happen

By DevOps Engineer•August 31, 2026•5 min read

Define RPO/RTO first

Recovery Point Objective (how much data loss is tolerable) and Recovery Time Objective (how long downtime lasts) decide everything: snapshot frequency, replica topology, and whether point-in-time recovery justifies its cost. Write both down with stakeholder sign-off.

The 3-2-1 baseline

Three copies, two media types, one off-site/off-region. For MongoDB Atlas: continuous cloud backups plus periodic export snapshots to independent storage. Automated, monitored, alerted — silent backup failures are the classic horror story.

The fire drill

Quarterly: restore to an isolated environment, verify app boot and data sanity, time the whole exercise. Untested backups are Schrödinger's backups. Document the runbook from the drill, not from theory — theory omits the IAM permission that blocks step four.
