Vault Disaster Recovery Procedures
PenguinMails safeguards all critical secrets inside HashiCorp Vault. This hub summarizes the recovery strategy, highlights recovery objectives, and routes teams to the detailed runbooks that keep secrets reachable when infrastructure fails or attackers strike.
Purpose
Vault protects SSH keys, SMTP credentials, API tokens, and DKIM signing keys. Losing access to those secrets halts VPS management, outbound email, and tenant integrations. These guides ensure recovery teams restore service quickly while containing risk and preserving compliance guarantees.
Recovery Objectives
| Scenario | RTO (hours) | RPO (hours) | Expected Impact |
|---|---|---|---|
| Vault server failure | 0.5 | 0 | Transparent failover inside the HA cluster |
| VPS compromise | 1 | 0 | Contained to affected tenant secrets |
| Vault compromise | 2-4 | 24 | Forced credential rotation platform-wide |
| Complete data center loss | 4-6 | 24 | Global impact until backup restoration completes |
