Common Questions

Q: How often are backups taken

A: Hourly for database (1-hour RPO), daily for configs/IaC. Monthly restore tests verify backups work.

Q: How long does recovery take

A: Depends on scenario. Pod restart: 2-3 min. Database recovery: 15-60 min. Full cluster: 2-4 hours.

Q: How much data can we lose

A: Maximum 1 hour (RPO = 1 hour). Worst case: lose transactions from last hour.

Q: Are backups encrypted

A: Yes. All backups use AES-256 encryption at rest. Stored in S3 with separate access keys.

Q: How do we know backups work

A: Monthly restore tests. We download a backup, restore to test database, and verify data integrity.

Q: What if the backup location fails

A: We have secondary backups in different region. Plus monthly archive copies to cold storage.

Q: Who runs the disaster recovery

A: Incident Commander (assigned during incident) directs response. Team follows procedures in runbooks.

Q: When is the next DR drill

A: Quarterly on last Friday of each quarter at 02:00 UTC. See Business Continuity Plan § Test Schedule.

Support & Escalation

If You Find an Issue

  1. Document the problem

    • What happened?
    • When did it happen?
    • How did you find it?

  2. Check the runbooks

    • Is it covered in procedures?
    • Try recommended solution

  3. Escalate if needed

    • Ask in #incident-critical
    • Page on-call engineer for critical issues

  4. Update documentation

    • If procedure unclear, suggest improvement
    • Submit PR to update runbooks
