Disaster Recovery Plan Example Small Business

Standard Operating Procedure: Disaster Recovery Plan (DRP)

1. Document Control Block

---

2. Executive Summary & Purpose

This document establishes the recovery protocols for critical business operations following a catastrophic failure. The purpose is to minimize Recovery Time Objective (RTO) and Recovery Point Objective (RPO), ensuring operational continuity with minimal data loss. This plan is designed for a lean, small-business architecture.

3. Scope & Prerequisites

Scope

• Covers cloud-based SaaS, local workstations, and primary data storage.
• Excludes physical facility rebuilding; focuses on digital restoration.

Prerequisites

• Off-site Backups: Immutable cloud storage (e.g., AWS S3 with Object Lock or Backblaze B2).
• Identity Management: Federated access to credentials (e.g., LastPass/1Password Team Vaults).
• Inventory: Hard-copy or offline digital export of asset serials and software licenses.
• PPE: Hardware repair kits (non-conductive tools, antistatic mats).

5. Step-by-Step Procedure

Phase I: Detection & Assessment

• Declare a Disaster: Verify service disruption exceeds the defined RTO (e.g., > 1 hour).
• Notify stakeholders via out-of-band communication (e.g., Signal, WhatsApp).
• Isolate compromised systems to prevent data leakage or propagation.

Phase II: Recovery Execution

• Infrastructure: Provision clean-room cloud instances or standby hardware.
• Identity: Rotate all administrative credentials stored in the Vault.
• Data Restoration: Initiate restore from last verified immutable backup (target RPO: < 24 hours).
• Verification: Perform checksum validation on restored databases.

Phase III: Resumption & Normalization

• Execute smoke tests on mission-critical applications.
• Re-route DNS and traffic to restored infrastructure.
• Update status pages/communication channels for clients.

6. Quality Assurance & Pro-Tips

Best Practices

• Immutable Backups: Always utilize "write-once-read-many" (WORM) storage to defeat ransomware.
• The 3-2-1 Rule: 3 copies of data, 2 different media, 1 off-site.
• Documentation: Maintain a physical "Black Book" containing recovery keys and emergency contacts.

Common Pitfalls

• Credential Lockout: Failure to maintain off-site access to password vaults.
• Forgotten Dependencies: Failing to document integration API keys for secondary services.

Metric Thresholds

• Target RTO: < 4 hours for mission-critical services.
• Target RPO: < 24 hours of data loss.

7. Frequently Asked Questions (FAQ)

Q: If my password vault is cloud-based, how do I access it during a total outage?

• A: Maintain a printed "Break-Glass" recovery key in a physical safe. Access the vault via a secondary device (mobile) not on the affected network.

Q: Should I pay the ransom if hit by ransomware?

• A: No. Paying does not guarantee data recovery and incentivizes further attacks. Trigger the "Clean Room" restore process immediately.

Q: How do I know if my backup is actually valid?

• A: Implement automated "Restore Drills." If you haven't tested the restore, the backup does not exist.
