Create Incident Recovery Plan

# Create Incident Recovery Plan

Act as an Engineering Manager creating an incident recovery plan.

## Recovery Plan Context
- **System**: [System/service name]
- **Criticality**: [Critical/High/Medium/Low]
- **Recovery Time Objective (RTO)**: [Target recovery time]
- **Recovery Point Objective (RPO)**: [Acceptable data loss window]

## Recovery Procedures

### 1. Pre-Incident Preparation

**Backup Strategy**:
- [ ] Database backups: [Frequency, retention]
- [ ] Configuration backups: [Frequency, retention]
- [ ] Code backups: [Version control, release tags]
- [ ] Backup verification: [How to verify backups]

**Disaster Recovery Infrastructure**:
- [ ] Secondary region/environment: [Location]
- [ ] Failover capabilities: [Active-passive/Active-active]
- [ ] Standby resources: [Resources available]
- [ ] DNS failover: [Configured/Load balancer]

**Documentation**:
- [ ] System architecture documented
- [ ] Dependencies mapped
- [ ] Recovery procedures documented
- [ ] Contact lists maintained

### 2. Recovery Decision Tree

**Scenario: Service Down**
- [ ] Check health endpoints
- [ ] Verify infrastructure status
- [ ] Review recent deployments
- [ ] Check logs for errors
- [ ] Option A: Rollback deployment
- [ ] Option B: Restart services
- [ ] Option C: Scale up resources
- [ ] Option D: Failover to secondary region

**Scenario: Data Corruption**
- [ ] Identify corrupted data
- [ ] Assess scope of corruption
- [ ] Option A: Restore from backup (if data loss acceptable)
- [ ] Option B: Repair corrupted data (if possible)
- [ ] Option C: Rebuild from source (if available)

**Scenario: Security Breach**
- [ ] Isolate affected systems
- [ ] Preserve evidence
- [ ] Notify security team
- [ ] Assess data exposure
- [ ] Restore from clean backup
- [ ] Deploy security patches

### 3. Rollback Procedures

**Deployment Rollback**:
- [ ] Identify deployment version
- [ ] Verify previous stable version
- [ ] Execute rollback: [Step-by-step commands]
- [ ] Verify rollback success
- [ ] Monitor system health
- [ ] Notify stakeholders

**Database Rollback**:
- [ ] Stop database writes
- [ ] Identify restore point
- [ ] Restore from backup: [Commands]
- [ ] Verify data integrity
- [ ] Resume database operations
- [ ] Monitor for issues

**Configuration Rollback**:
- [ ] Identify configuration change
- [ ] Restore previous configuration
- [ ] Restart affected services
- [ ] Verify configuration applied
- [ ] Monitor system behavior

### 4. Failover Procedures

**Active-Passive Failover**:
- [ ] Verify secondary region health
- [ ] Stop primary region traffic
- [ ] Update DNS/load balancer
- [ ] Verify failover success
- [ ] Monitor secondary region
- [ ] Document failover event

**Active-Active Failover**:
- [ ] Identify failing region
- [ ] Drain traffic from failing region
- [ ] Redirect traffic to healthy region
- [ ] Monitor traffic distribution
- [ ] Verify service continuity

**Database Failover**:
- [ ] Identify primary database failure
- [ ] Promote secondary database
- [ ] Update connection strings
- [ ] Verify database connectivity
- [ ] Monitor replication lag

### 5. Data Recovery Procedures

**Database Recovery**:
- [ ] Identify data loss/corruption
- [ ] Stop data writes
- [ ] Select restore point (within RPO)
- [ ] Restore database: [Commands]
- [ ] Verify data integrity
- [ ] Resume operations

**File System Recovery**:
- [ ] Identify lost/corrupted files
- [ ] Restore from backup: [Commands]
- [ ] Verify file integrity
- [ ] Restore permissions
- [ ] Resume file operations

**Application State Recovery**:
- [ ] Identify lost state
- [ ] Restore from checkpoint/backup
- [ ] Replay logs if available
- [ ] Verify state consistency
- [ ] Resume application operations

### 6. Service Restoration Workflow

**Step 1: Assess Impact**
- [ ] What services are affected?
- [ ] How many users impacted?
- [ ] What functionality is broken?
- [ ] What data is at risk?

**Step 2: Choose Recovery Strategy**
- [ ] Quick fix/workaround available?
- [ ] Rollback possible?
- [ ] Failover needed?
- [ ] Full restoration required?

**Step 3: Execute Recovery**
- [ ] Execute recovery procedures
- [ ] Monitor recovery progress
- [ ] Verify recovery success
- [ ] Document actions taken

**Step 4: Validate Recovery**
- [ ] Test critical functionality
- [ ] Verify data integrity
- [ ] Monitor error rates
- [ ] Confirm user impact resolved

**Step 5: Post-Recovery**
- [ ] Update status page
- [ ] Notify stakeholders
- [ ] Schedule post-incident review
- [ ] Update documentation

### 7. Recovery Testing

**Test Scenarios**:
- [ ] Database failure recovery
- [ ] Deployment rollback
- [ ] Region failover
- [ ] Data corruption recovery
- [ ] Security incident recovery

**Testing Schedule**:
- [ ] Quarterly: [Full disaster recovery test]
- [ ] Monthly: [Component recovery tests]
- [ ] Weekly: [Backup verification]

**Test Documentation**:
- [ ] Test results recorded
- [ ] Recovery time measured
- [ ] Issues documented
- [ ] Improvements identified

**Automation Scripts**:
- [ ] Rollback script: [Location]
- [ ] Failover script: [Location]
- [ ] Database restore script: [Location]
- [ ] Health check script: [Location]

**Monitoring Tools**:
- [ ] [Tool] - [Purpose]
