feat(6): phase 6 plan 02 - operational runbook and documentation

- Created OPERATIONAL_RUNBOOK.md: comprehensive step-by-step procedures for both Docker and Standalone deployment modes covering deployment, daily ops, troubleshooting, backup/restore, disaster recovery, scaling, and updates - Created HEALTH_MONITORING_CHECKLIST.md: daily/weekly/monthly health check procedures with alert thresholds and quick troubleshooting reference - Created DISASTER_RECOVERY_PLAN.md: detailed procedures for 6 failure scenarios (database corruption, hardware failure, data center failure, app crash, disk full, network isolation) with RTO/RPO targets - Created CONFIGURATION_REFERENCE.md: complete documentation of all inventory.env parameters for both deployment modes with common scenarios and troubleshooting - Created EMERGENCY_PROCEDURES.md: quick-reference incident response playbook with 7 critical scenarios, decision tree, escalation path, and printable cheat sheet - Created scripts/backup.sh: automated backup script supporting both Docker and Standalone with integrity verification and retention management - Created scripts/restore.sh: restore script with triple confirmation, safety backups, and validation tests for both deployment modes - Created config/backup-cron.sh: installer for daily/weekly automated backup cron jobs (2 AM daily, 3 AM Sunday) All documentation covers dual-deployment modes with shared configuration files. Documentation is operator-ready with copy-paste commands and clear expected outputs.

+# Configuration Reference
+
+**Purpose**: Document all configuration parameters for both Docker and Standalone deployment modes.  
+**Shared Config**: inventory.env (used by both modes)  
+**Last Updated**: 2026-04-22
+
+---
+
+## Overview
+
+Both Docker and Standalone deployment modes use the same `inventory.env` configuration file. All parameters are documented here with defaults, ranges, and examples.
+
+---
+
+## inventory.env Parameters
+
+### Network & Server Configuration
+
+```bash
+# Backend API server port (Docker exposed on this port)
+BACKEND_PORT=8000
+# Default: 8000
+# Range: 1024-65535
+# Common: 8000, 8080, 5000
+
+# Frontend server port
+FRONTEND_PORT=3000
+# Default: 3000
+# Range: 1024-65535
+# Common: 3000, 3001, 8888
+
+# Host binding (0.0.0.0 = all interfaces, 127.0.0.1 = localhost only)
+BACKEND_HOST=0.0.0.0
+FRONTEND_HOST=0.0.0.0
+# Use 127.0.0.1 for development only, 0.0.0.0 for production
+
+# External server address (for CORS and frontend API calls)
+SERVER_URL=http://localhost:8000
+# Example for production: http://inventory.example.com:8000
+# Or with HTTPS: https://inventory.example.com
+```
+
+### Security & Authentication
+
+```bash
+# JWT secret key for API authentication (generate with: openssl rand -hex 32)
+JWT_SECRET_KEY=your-generated-hex-string-here
+# Min length: 32 characters
+# IMPORTANT: Change this in production
+# Generation: openssl rand -hex 32
+
+# Algorithm for JWT signing
+JWT_ALGORITHM=HS256
+# Default: HS256
+# Options: HS256, HS384, HS512
+
+# LDAP server configuration (optional, for enterprise auth)
+LDAP_SERVER=ldap.example.com
+LDAP_PORT=389
+LDAP_BIND_DN=cn=admin,dc=example,dc=com
+LDAP_BASE_DN=ou=users,dc=example,dc=com
+LDAP_USE_SSL=false
+# Set to empty/false to disable LDAP (use local auth only)
+
+# Password hashing iterations (PBKDF2)
+PASSWORD_HASH_ITERATIONS=100000
+# Default: 100000
+# Higher = more secure but slower
+```
+
+### Database Configuration
+
+```bash
+# Database file location
+DATABASE_URL=sqlite:///./data/inventory.db
+# For Docker: Use /app/data/inventory.db inside container
+# For Standalone: Use ./data/inventory.db
+
+# Database connection pool size
+DB_POOL_SIZE=10
+# Default: 10
+# Increase for 10+ concurrent users
+# Docker: Keep <20 due to SQLite single-writer
+# Standalone: Keep <15
+
+# Database WAL mode (write-ahead logging, improves concurrency)
+DATABASE_JOURNAL_MODE=WAL
+# Default: WAL
+# Options: WAL, DELETE
+# WAL = better concurrency, more disk space
+# DELETE = less disk, slower writes
+```
+
+### AI Provider Configuration
+
+```bash
+# Primary AI provider (gemini or claude)
+PRIMARY_AI_PROVIDER=gemini
+# Options: gemini, claude
+# Default: gemini (more cost-effective)
+
+# Google Gemini API key (for label extraction)
+GEMINI_API_KEY=your-api-key-here
+# Get from: https://aistudio.google.com/app/apikeys
+# Leave empty to disable Gemini
+
+# Anthropic Claude API key (for label extraction)
+CLAUDE_API_KEY=your-api-key-here
+# Get from: https://console.anthropic.com/
+# Leave empty to disable Claude
+
+# AI model selection
+GEMINI_MODEL=gemini-2.0-flash
+CLAUDE_MODEL=claude-3-5-sonnet-20241022
+# Use latest stable versions available
+
+# AI image processing mode (box or standard)

+```
+
+---
+
+## Docker-Specific Configuration
+
+### docker-compose.yml
+
+These are handled by the deployment but documented for reference:
+
+```yaml
+# Backend service
+backend:
+  environment:
+    - DATABASE_URL=sqlite:////app/data/inventory.db
+    - LOG_FILE=/app/logs/backend.log
+    - PYTHONUNBUFFERED=1
+  ports:
+    - "${BACKEND_PORT}:8000"
+  volumes:
+    - ./data:/app/data
+    - ./config:/app/config
+    - ./logs:/app/logs
+
+# Frontend service
+frontend:
+  environment:
+    - NEXT_PUBLIC_API_URL=http://localhost:${BACKEND_PORT}
+  ports:
+    - "${FRONTEND_PORT}:3000"
+
+# Proxy service (Caddy)
+proxy:
+  ports:
+    - "8909:8909"  # HTTPS proxy
+  volumes:
+    - ./data/caddy_data:/data
+    - ./data/caddy_config:/config
+```
+
+---
+
+## Standalone-Specific Configuration
+
+### Environment Variables for start_server.sh
+
+The script reads from `inventory.env` and sets up:
+
+```bash
+# Python environment
+PYTHONUNBUFFERED=1  # Direct logging output
+PYTHONPATH=./backend
+
+# Node environment
+NODE_ENV=production
+
+# Paths
+BACKEND_DIR=./backend
+FRONTEND_DIR=./frontend
+DATA_DIR=./data
+LOGS_DIR=./logs
+```
+
+---
+
+## Configuration Validation
+
+### Pre-Deployment Checks
+
+Run these to validate configuration before starting services:
+
+```bash
+# Docker mode
+./deploy.sh validate
+
+# Standalone mode
+python3 backend/config_manager.py --validate
+
+# Manual checks
+[ -f inventory.env ] && echo "✓ inventory.env exists"
+[ -d data ] && echo "✓ data directory exists"
+[ -d logs ] && echo "✓ logs directory exists"
+openssl rand -hex 32 > /dev/null && echo "✓ OpenSSL available"
+```
+
+---
+
+## Common Configuration Scenarios
+
+### Scenario 1: Local Development
+
+```bash
+BACKEND_PORT=8000
+FRONTEND_PORT=3000
+BACKEND_HOST=127.0.0.1
+JWT_SECRET_KEY=dev-key-not-for-production
+LOG_LEVEL=DEBUG
+ENVIRONMENT=development
+ENABLE_AI_EXTRACTION=false  # Save API costs
+```
+
+### Scenario 2: Single-Server Production
+
+```bash
+BACKEND_PORT=8000
+FRONTEND_PORT=3000
+BACKEND_HOST=0.0.0.0
+SERVER_URL=https://inventory.example.com
+JWT_SECRET_KEY=<generate-with-openssl>
+LOG_LEVEL=INFO
+ENVIRONMENT=production
+PRIMARY_AI_PROVIDER=gemini
+GEMINI_API_KEY=<your-api-key>
+```
+
+### Scenario 3: High Concurrency (Standalone)
+
+```bash
+DB_POOL_SIZE=15
+WORKERS=8  # (2 x CPUs) + 1
+REQUEST_TIMEOUT=45
+DATABASE_TIMEOUT=15
+LOG_LEVEL=WARNING  # Reduce I/O for performance
+```
+
+### Scenario 4: LDAP Enterprise Auth
+
+```bash
+LDAP_SERVER=ldap.company.com
+LDAP_PORT=389
+LDAP_BIND_DN=cn=admin,dc=company,dc=com
+LDAP_BASE_DN=ou=people,dc=company,dc=com
+LDAP_USE_SSL=true
+# Users login with their LDAP credentials
+```
+
+---
+
+## Troubleshooting Configuration Issues
+
+### Port Already in Use
+
+```bash
+# Find process using port
+lsof -i :8000
+netstat -tuln | grep 8000
+
+# Solution: Change BACKEND_PORT or kill process
+```
+
+### JWT Secret Not Set
+
+```bash
+# Generate new secret
+openssl rand -hex 32
+
+# Add to inventory.env
+echo "JWT_SECRET_KEY=$(openssl rand -hex 32)" >> inventory.env
+```
+
+### Database Connection Error
+
+```bash
+# Check database file exists
+ls -la data/inventory.db
+
+# Check permissions
+chmod 644 data/inventory.db
+
+# Reset if corrupted
+rm data/inventory.db
+# (Backup will be restored on next startup)
+```
+
+### LDAP Authentication Failing
+
+```bash
+# Test LDAP connection
+ldapsearch -x -H ldap://ldap.company.com:389 -D "cn=admin,dc=company,dc=com"
+
+# Check configuration matches LDAP schema
+# May need to adjust LDAP_BASE_DN or LDAP_BIND_DN
+```
+
+---
+
+## Environment Variable Precedence
+
+Configuration is loaded in this order:
+
+1. Defaults (hardcoded in code)
+2. `inventory.env` file
+3. OS environment variables (override)
+4. Command-line arguments (highest priority)
+
+Example override:
+```bash
+BACKEND_PORT=9000 ./deploy.sh production
+```
+
+---
+
+## Security Best Practices
+
+- [ ] Generate unique JWT_SECRET_KEY for each environment
+- [ ] Never commit `inventory.env` to git (add to `.gitignore`)
+- [ ] Use HTTPS in production (configure reverse proxy)
+- [ ] Rotate LDAP passwords quarterly
+- [ ] Limit ALLOWED_ORIGINS to known domains
+- [ ] Use strong JWT_ALGORITHM (HS256 minimum)
+- [ ] Monitor LOG_LEVEL in production (avoid DEBUG)

+# Deployment Quick Start Guide
+
+## Overview
+
+This guide covers two deployment methods for TFM aInventory:
+1. **Docker Mode** - Full containerized deployment using Docker Compose
+2. **Standalone Mode** - Direct server startup without Docker
+
+Both modes use the same configuration files and can be switched between freely.
+
+---
+
+## Prerequisites
+
+### Minimum Requirements
+- Ubuntu 22.04 LTS or similar Linux distro
+- 2GB RAM
+- 10GB free disk space
+
+### For Docker Mode
+- Docker 24.0+ (`docker --version`)
+- Docker Compose 2.0+ (`docker-compose --version`)
+
+### For Standalone Mode
+- Python 3.12+ (`python3 --version`)
+- Node.js 20+ (`node --version`)
+- npm 10+ (`npm --version`)
+
+---
+
+## Quick Start (Docker Mode)
+
+### Step 1: Prepare Environment
+```bash
+git clone <repository-url> tfm-inventory
+cd tfm-inventory
+cp inventory.env.template inventory.env
+
+# Edit inventory.env to customize ports and settings
+nano inventory.env
+```
+
+### Step 2: Generate Secure Secret
+```bash
+# Generate a 32-byte hex string for JWT_SECRET_KEY
+openssl rand -hex 32
+
+# Copy the output and paste it into inventory.env as JWT_SECRET_KEY value
+```
+
+### Step 3: Deploy with Docker
+```bash
+chmod +x deploy.sh
+./deploy.sh production
+```
+
+The script will:
+- Validate prerequisites (Docker, disk space, ports)
+- Build Docker images
+- Create necessary data directories
+- Start all services in background
+- Wait for health checks (max 60 seconds)
+- Display access URLs and next steps
+
+### Step 4: Verify Access
+Open your browser:
+- **Frontend**: http://localhost:3000
+- **Backend API Docs**: http://localhost:8000/docs
+- **HTTPS (Secure)**: https://localhost:8919
+
+---
+
+## Quick Start (Standalone Mode)
+
+### Step 1: Prepare Environment
+```bash
+cd tfm-inventory
+cp inventory.env.template inventory.env
+
+# Edit configuration as needed
+nano inventory.env
+```
+
+### Step 2: Install Dependencies
+```bash
+# Backend dependencies
+cd backend
+pip install -r requirements.txt
+cd ..
+
+# Frontend dependencies
+cd frontend
+npm ci
+npm run build
+cd ..
+```
+
+### Step 3: Start Servers
+```bash
+chmod +x start_server.sh
+./start_server.sh
+```
+
+The script will:
+- Check prerequisites (Python, Node.js, ports)
+- Create data directories
+- Install missing dependencies
+- Initialize database if needed
+- Start backend API server
+- Start frontend web server
+
+### Step 4: Access the Application
+- **Frontend**: http://localhost:3000
+- **Backend API**: http://localhost:8000
+- **API Documentation**: http://localhost:8000/docs
+
+---
+
+## Configuration
+
+### Key Settings in inventory.env
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `BACKEND_PORT` | 8000 | Backend API port |
+| `FRONTEND_PORT` | 3000 | Frontend web server port |
+| `JWT_SECRET_KEY` | - | **REQUIRED**: Generate with `openssl rand -hex 32` |
+| `LOG_LEVEL` | INFO | Log verbosity: DEBUG, INFO, WARNING, ERROR |
+| `DATA_DIR` | ./data | Data files location (database, certs, etc.) |
+| `LOGS_DIR` | ./logs | Log files location |
+| `AI_PROVIDER` | - | Optional: gemini, claude (if API keys provided) |
+| `LDAP_SERVER` | - | Optional: LDAP server for authentication |
+
+### First-Time Setup
+
+On first deployment:
+1. Database is automatically initialized
+2. Caddy HTTPS certificates are generated (may show browser warning on first access)
+3. Default admin user may be created (check logs)
+
+---
+
+## Switching Between Modes
+
+### Docker to Standalone
+```bash
+# Stop Docker services
+docker-compose down
+
+# Start standalone services
+./start_server.sh
+```
+
+### Standalone to Docker
+```bash
+# Stop standalone processes (Ctrl+C or kill PID)
+# Then start Docker
+./deploy.sh production
+```
+
+Both modes read the same `inventory.env`, so configuration is preserved.
+
+---
+
+## Common Tasks
+
+### View Logs
+
+**Docker Mode:**
+```bash
+# All services
+docker-compose logs -f
+
+# Specific service
+docker-compose logs -f backend
+docker-compose logs -f frontend
+```
+
+**Standalone Mode:**
+```bash
+# Backend
+tail -f logs/backend.log
+
+# Frontend
+tail -f logs/frontend.log
+```
+
+### Stop Services
+
+**Docker Mode:**
+```bash
+docker-compose down
+```
+
+**Standalone Mode:**
+```bash
+# Press Ctrl+C in the terminal where start_server.sh is running
+# Or find and kill the processes
+ps aux | grep -E "uvicorn|node.*server"
+kill <PID>
+```
+
+### Change Ports
+
+1. Edit `inventory.env`
+2. Change `BACKEND_PORT` and/or `FRONTEND_PORT`
+3. Redeploy:
+   - Docker: `./deploy.sh production`
+   - Standalone: `./start_server.sh`
+
+### Check Health Status
+
+**Docker Mode:**
+```bash
+docker-compose ps
+# All services should show "healthy" status
+
+# Or call health endpoint
+curl http://localhost:8000/health
+```
+
+**Standalone Mode:**
+```bash
+curl http://localhost:8000/health
+curl http://localhost:3000/
+```
+
+---
+
+## Troubleshooting
+
+### Port Already in Use
+**Error**: `Port XXXX already in use`
+
+**Solution**:
+1. Find what's using the port: `lsof -i :XXXX` or `netstat -tuln | grep XXXX`
+2. Stop the application: `kill <PID>`
+3. Or change the port in `inventory.env`
+
+### Health Check Timeout
+**Error**: `Services did not become healthy within timeout`
+
+**Solution**:
+1. Check logs: `docker-compose logs` (Docker) or `tail -f logs/*.log` (Standalone)
+2. Common causes:
+   - Insufficient disk space
+   - Database initialization slow on first run
+   - Port still in use by old process
+3. Retry: `./deploy.sh production` (Docker) or restart (Standalone)
+
+### Database Locked
+**Error**: `database is locked`
+
+**Solution**:
+```bash
+# Docker: Restart backend
+docker-compose restart backend
+
+# Standalone: Kill and restart
+kill <backend-pid>
+./start_server.sh
+```
+
+### HTTPS Certificate Warning
+**Issue**: Browser shows certificate warning on first access
+
+**Explanation**: Caddy generates self-signed certificates for local HTTPS. This is normal and secure.
+
+**Solution**: Click "Advanced" and "Proceed Anyway" (Chrome) or similar button. The warning will not reappear once the certificate is accepted.
+
+### Can't Access Frontend/Backend
+**Error**: Connection refused or timeout
+
+**Debugging**:
+```bash
+# Check if service is running
+docker-compose ps  # Docker
+ps aux | grep -E "uvicorn|node"  # Standalone
+
+# Check if port is listening
+netstat -tuln | grep -E "8000|3000"
+
+# Test direct connection
+curl http://localhost:8000/health
+curl http://localhost:3000/
+```
+
+---
+
+## Performance & Scaling
+
+### Single-Instance System
+This deployment is optimized for single-instance operation:
+- Database: SQLite (embedded)
+- Storage: Local filesystem
+- Capacity: ~5 concurrent users, ~10K items
+
+### Monitoring Performance
+```bash
+# Check process resource usage (Docker)
+docker stats
+
+# Check logs for slow queries
+docker-compose logs backend | grep "duration"
+```
+
+### Backup & Recovery
+See `docs/BACKUP_RUNBOOK.md` for detailed backup procedures.
+
+---
+
+## Production Deployment
+
+### Before Going Live
+1. [ ] Change `JWT_SECRET_KEY` to a secure value
+2. [ ] Update `ALLOWED_ORIGINS` to match your domain
+3. [ ] Set `LOG_LEVEL=WARNING` to reduce log volume
+4. [ ] Test the application thoroughly
+5. [ ] Set up automated backups
+6. [ ] Configure firewall to expose only required ports (3000, 8000, 443)
+7. [ ] Review `inventory.env` for all sensitive values
+
+### Production Checklist
+```bash
+# Pre-deployment validation
+bash .env.validation.sh
+
+# Deploy
+./deploy.sh production
+
+# Verify all services
+docker-compose ps
+curl https://your-domain:8919/  # HTTPS frontend
+
+# Monitor logs
+docker-compose logs -f
+```
+
+### Ongoing Maintenance
+- Monitor logs daily
+- Check health status weekly
+- Perform backups daily/weekly per your retention policy
+- Review resource usage monthly
+
+---
+
+## Support & Logs
+
+### Enable Debug Logging
+Edit `inventory.env`:
+```bash
+LOG_LEVEL=DEBUG
+```
+
+Then redeploy or restart services.
+
+### Collect Diagnostic Information
+```bash
+# Docker
+docker-compose logs --tail=200 > diagnostics.log
+docker-compose ps >> diagnostics.log
+docker stats --no-stream >> diagnostics.log
+
+# Standalone
+tail -100 logs/*.log > diagnostics.log
+ps aux | grep -E "uvicorn|node" >> diagnostics.log
+```
+
+---

+# Disaster Recovery Plan
+
+**Objective**: Restore production service within 10 minutes and zero data loss.  
+**Status**: Active  
+**Last Tested**: [Date]  
+**Next Review**: 2026-05-22
+
+---
+
+## Overview
+
+This document outlines procedures for recovering from various failure scenarios. The system uses automated daily backups with a 1-day RPO (Recovery Point Objective) and aims for <10 minute RTO (Recovery Time Objective).
+
+---
+
+## Scenarios & Recovery Procedures
+
+### Scenario 1: Database Corrupted
+
+**Detection**:
+- Integrity check fails: `PRAGMA integrity_check;`
+- Data unexpectedly missing
+- Queries returning errors
+
+**Recovery Steps (Docker)**:
+```bash
+# 1. Verify corruption
+docker-compose exec backend sqlite3 /app/data/inventory.db "PRAGMA integrity_check;"
+
+# 2. Stop services
+docker-compose down
+
+# 3. Restore from backup
+./scripts/restore.sh backups/latest.tar.gz --validate
+
+# 4. Verify data integrity
+docker-compose exec backend sqlite3 /app/data/inventory.db "SELECT COUNT(*) FROM items;"
+```
+
+**Recovery Steps (Standalone)**:
+```bash
+# 1. Verify corruption
+sqlite3 data/inventory.db "PRAGMA integrity_check;"
+
+# 2. Stop services
+pkill -f uvicorn
+pkill -f "next start"
+
+# 3. Restore from backup
+./scripts/restore.sh backups/latest.tar.gz
+
+# 4. Start services
+./start_server.sh
+
+# 5. Verify
+sqlite3 data/inventory.db "SELECT COUNT(*) FROM items;"
+```
+
+**RTO**: <10 minutes  
+**RPO**: 1 day  
+**Notify Users**: If data loss within last 24 hours
+
+---
+
+### Scenario 2: Complete Hardware Failure
+
+**Detection**:
+- Server doesn't boot
+- Server not reachable on network
+- Docker daemon won't start
+
+**Recovery Steps**:
+```bash
+# 1. Provision new Ubuntu 22.04 LTS server
+#    Same specs as original (2GB+ RAM, 10GB+ disk)
+
+# 2. Clone repository
+git clone <repo_url> /opt/tfm-inventory
+cd /opt/tfm-inventory
+
+# 3. Copy backup from offsite storage
+#    (Assuming you have offsite backup copy)
+cp /path/to/offsite/backup-latest.tar.gz ./backups/
+
+# 4. Restore
+./scripts/restore.sh backups/backup-latest.tar.gz --validate
+
+# 5. Update DNS/load balancer to new IP
+
+# 6. Verify services
+curl http://localhost:8000/health
+curl http://localhost:3000
+```
+
+**RTO**: <30 minutes (depends on provisioning speed)  
+**RPO**: 1 day  
+**Estimated Cost**: New hardware provisioning
+
+---
+
+### Scenario 3: Data Center Failure
+
+**Detection**:
+- Entire data center unreachable
+- Multiple systems down simultaneously
+- Network infrastructure down
+
+**Recovery Steps**:
+```bash
+# 1. Activate secondary site (if available)
+#    or failover to cloud provider
+
+# 2. Provision new infrastructure
+#    Clone repository on new infrastructure
+
+# 3. Restore latest backup
+git clone <repo> /opt/tfm-inventory
+cd /opt/tfm-inventory
+./scripts/restore.sh /offsite/backup-latest.tar.gz --validate
+
+# 4. Update DNS to new location
+#    (Allow 5-15 min for DNS propagation)
+
+# 5. Notify users
+#    "Service restored; data loss = last 1 day"
+```
+
+**RTO**: 30-60 minutes (depends on secondary readiness)  
+**RPO**: 1 day  
+**Prevention**: Maintain offsite backup copy at minimum
+
+---
+
+### Scenario 4: Application Crash / Memory Leak
+
+**Detection**:
+- Backend crashes and won't restart
+- Frontend crashes
+- Memory continuously growing
+
+**Recovery Steps**:
+```bash
+# Docker mode:
+docker-compose logs backend | tail -100
+
+# If memory leak:
+docker-compose restart backend
+
+# If crash persists:
+git log --oneline | head -10
+git revert <commit-hash>
+./deploy.sh production
+
+# Standalone mode:
+tail -100 logs/backend.log
+
+pkill -9 -f uvicorn
+./start_server.sh
+
+# If crash persists:
+git revert <problematic-commit>
+./start_server.sh
+```
+
+**RTO**: <5 minutes (restart)  
+**RPO**: 0 (no data loss, running services)
+
+---
+
+### Scenario 5: Disk Full
+
+**Detection**:
+- `df -h` shows 100% usage
+- Write operations failing
+- Backup script failing
+
+**Recovery Steps**:
+```bash
+# 1. Identify large directories
+du -sh /* | sort -rh | head -10
+
+# 2. Clean old backups
+find backups/ -name "*.tar.gz" -mtime +7 -delete
+
+# 3. Clear logs if very large
+find logs/ -name "*.log" -mtime +30 -delete
+
+# 4. Extend disk volume
+#    (Depends on cloud provider or physical hardware)
+
+# 5. Verify
+df -h
+```
+
+**RTO**: <15 minutes  
+**RPO**: 0 (no data loss)
+
+---
+
+### Scenario 6: Network Isolation / CORS Issues
+
+**Detection**:
+- Frontend can't reach backend API
+- CORS errors in browser console
+- API reachable locally but not from network
+
+**Recovery Steps**:
+```bash
+# 1. Check network connectivity
+ping <backend-ip>
+curl -v http://backend-ip:8000/health
+
+# 2. Check CORS configuration
+docker-compose exec backend python -c "
+from backend.config import ALLOWED_ORIGINS
+print(ALLOWED_ORIGINS)
+"
+
+# 3. Update CORS if needed
+# Edit inventory.env:
+# EXTRA_ALLOWED_ORIGINS=<your-ip>
+
+# 4. Restart backend
+docker-compose restart backend
+
+# 5. Verify
+curl http://localhost:8000/health
+```
+
+**RTO**: <5 minutes  
+**RPO**: 0
+
+---
+
+## Regular Testing
+
+### Monthly Backup Test
+
+Run on **staging environment** (not production):
+
+```bash
+# 1. List available backups
+ls -lh backups/
+
+# 2. Restore latest
+./scripts/restore.sh backups/latest.tar.gz --validate
+
+# 3. Verify checklist
+- [ ] Restore completes without errors
+- [ ] All services start correctly
+- [ ] Database passes integrity check
+- [ ] Item count matches expectation (e.g., 10K+ items)
+- [ ] API responds at /health
+- [ ] Frontend loads without errors
+- [ ] Can login with test account
+```
+
+### Quarterly Full Failover Drill
+
+Once per quarter, perform complete failover simulation:
+
+```bash
+# 1. Provision staging server with identical specs
+# 2. Restore production backup
+# 3. Run health checklist
+# 4. Simulate 5 concurrent users (if load testing available)
+# 5. Document any issues
+# 6. Update this plan based on findings
+```
+
+### Annual Disaster Recovery Exercise
+
+Once per year:
+- Simulate data center failure
+- Activate secondary site (if exists)
+- Full restore on new infrastructure
+- Involve all ops team members
+- Document timeline and issues
+- Update RTO/RPO estimates
+
+---
+
+## Prevention & Mitigation
+
+| Layer | Prevention | Implementation |
+|-------|-----------|-----------------|
+| **Backup** | Daily automated | Cron jobs, 30-day rotation |
+| **Offsite Backup** | Weekly copy to cloud | S3/GCS bucket, encrypted |
+| **Monitoring** | Alert on issues | CPU >70%, disk >80%, API down |
+| **Redundancy** | Secondary instance | v3 feature (not in v2 scope) |
+| **Testing** | Monthly restore drill | Staging environment |
+| **Documentation** | Up-to-date runbooks | Review quarterly |
+
+---
+
+## Offsite Backup Setup (Recommended)
+
+To prevent total data loss in case of hardware failure:
+
+```bash
+# Weekly copy to cloud storage (add to cron)
+0 4 * * 0 cd /opt/tfm-inventory && \
+  gsutil -m cp backups/inventory-*.tar.gz \
+  gs://your-backup-bucket/tfm-inventory/ || \
+  aws s3 sync backups/ s3://your-bucket/tfm-inventory/
+
+# Or to another server
+0 4 * * 0 cd /opt/tfm-inventory && \
+  rsync -avz backups/ backup-server:/backups/tfm-inventory/
+```
+
+---
+
+## Communication Plan
+
+### During Incident
+
+1. **Immediate** (notify immediately):
+   - CEO / Project Lead
+   - Affected users
+   - Operations team
+
+2. **Message Template**:
+   ```
+   Service Status: [DEGRADED|DOWN]
+   Impact: Inventory system unavailable
+   ETA: <estimated recovery time>
+   Action: We are restoring from backup
+   ```
+
+3. **Updates**: Every 5 minutes or when status changes
+
+### After Recovery
+
+1. **Post-incident Review**: Within 48 hours
+   - What failed?
+   - Why did it fail?
+   - How do we prevent it?
+   - Update this plan
+
+2. **Root Cause Analysis**: Within 1 week
+3. **Implement Fixes**: Within 2 weeks
+
+---
+
+## Success Criteria
+
+For recovery to be considered successful:
+
+- [ ] Restore completes in <10 minutes (target)
+- [ ] Zero data loss (max 1 day RPO acceptable)
+- [ ] All services healthy post-restore
+- [ ] Users can login and access inventory
+- [ ] API responds at /health with 200 OK
+- [ ] Database integrity verified
+- [ ] Audit logs preserved (immutable)
+- [ ] Monthly test succeeds 100%

+# Emergency Procedures
+
+**Purpose**: Quick reference for critical incident response.  
+**Audience**: On-call operations team  
+**Response Time Goal**: <5 minutes to action, <10 minutes to recovery
+
+---
+
+## Quick Response Matrix
+
+| Issue | Detection | Immediate Action | Recovery Time |
+|-------|-----------|------------------|-----------------|
+| **Service Down** | Ping fails / curl fails | Restart service | 2-3 min |
+| **API Unresponsive** | /health returns error | Restart backend | 3-5 min |
+| **Database Locked** | "Database is locked" error | Restart backend | 3-5 min |
+| **High Memory** | `docker stats` >80% | Kill & restart | 5 min |
+| **Disk Full** | `df -h` >90% | Clean backups | 5 min |
+| **Data Corruption** | Integrity check fails | Restore backup | 8-10 min |
+
+---
+
+## Emergency Response Playbook
+
+### INCIDENT 1: Service Down (10 min recovery target)
+
+**Detection**: `curl http://localhost:8000/health` returns nothing or "connection refused"
+
+**Immediate (30 seconds)**:
+```bash
+# Check service status
+docker-compose ps  # Docker mode
+ps aux | grep uvicorn  # Standalone mode
+
+# Check if port is actually in use
+netstat -tuln | grep 8000
+```
+
+**Diagnosis (1 minute)**:
+```bash
+# Docker mode
+docker-compose logs backend | tail -50
+
+# Standalone mode
+tail -50 logs/backend.log
+```
+
+**Recovery (Docker, <3 minutes)**:
+```bash
+# Option 1: Restart service
+docker-compose restart backend
+
+# Option 2: Full restart (if restart fails)
+docker-compose down
+docker-compose up -d
+
+# Option 3: Emergency (hard reset)
+docker-compose down
+rm -f data/inventory.db-*  # Remove lock files
+docker-compose up -d
+```
+
+**Recovery (Standalone, <3 minutes)**:
+```bash
+# Kill process
+pkill -9 -f uvicorn
+
+# Wait for port to release
+sleep 3
+
+# Restart service
+cd backend && source venv/bin/activate && \
+  uvicorn main:app --host 0.0.0.0 --port 8000 &
+```
+
+**Verification**:
+```bash
+curl -v http://localhost:8000/health
+# Expected: HTTP 200 OK, response time <100ms
+```
+
+**Escalate if**: Still not responsive after 5 minutes → Check logs → Call developer support
+
+---
+
+### INCIDENT 2: Database Locked (5 min recovery target)
+
+**Detection**: Requests returning "database is locked" errors
+
+**Immediate (30 seconds)**:
+```bash
+# Docker mode
+docker-compose logs backend | grep -i "locked" | tail -10
+
+# Standalone mode
+tail -20 logs/backend.log | grep -i "locked"
+```
+
+**Recovery**:
+```bash
+# Docker mode
+docker-compose restart backend
+
+# Standalone mode
+pkill -9 -f uvicorn
+sleep 2
+./start_server.sh
+```
+
+**Verify**:
+```bash
+curl http://localhost:8000/health
+# Should respond with 200 OK
+```
+
+**If still failing**: Restore from backup → See INCIDENT 5
+
+---
+
+### INCIDENT 3: High CPU/Memory (5 min recovery target)
+
+**Detection**: `docker stats` shows >70% CPU or >500MB RAM for backend
+
+**Immediate (30 seconds)**:
+```bash
+# Check resource usage
+docker stats --no-stream  # Docker
+ps aux | grep uvicorn  # Standalone
+
+# Kill slow query (if identifiable)
+docker-compose logs backend | grep "slow" | tail -5
+```
+
+**Recovery**:
+```bash
+# Option 1: Restart service
+docker-compose restart backend  # Docker
+pkill -f uvicorn  # Standalone
+
+# Option 2: Limit resources (Docker only)
+# Edit docker-compose.yml:
+# backend:
+#   mem_limit: 1g
+
+# Option 3: Investigate slow queries
+docker-compose exec backend python -c "
+import backend.models
+from backend.db import SessionLocal
+db = SessionLocal()
+# Run diagnostic queries
+"
+```
+
+**Monitor**: Watch for 10 minutes after restart to ensure stable
+
+---
+
+### INCIDENT 4: Disk Full (5 min recovery target)
+
+**Detection**: `df -h` shows 90%+ usage, write operations failing
+
+**Immediate (1 minute)**:
+```bash
+# Check disk usage
+du -sh /* | sort -rh | head -10
+
+# Identify largest items
+du -sh data/ backups/ logs/
+```
+
+**Recovery (order of priority)**:
+```bash
+# 1. Delete old backups (usually >90% of disk)
+find backups/ -name "inventory-*.tar.gz" -mtime +7 -delete
+# Safe: Backups older than 7 days
+# Aggressive: -mtime +3 (3 days)
+
+# 2. Compress old logs
+gzip logs/*.log.* 2>/dev/null || true
+find logs/ -name "*.gz" -mtime +30 -delete
+
+# 3. Vacuum database (if >500MB)
+sqlite3 data/inventory.db "VACUUM;"
+
+# 4. Delete oldest backups if still full
+find backups/ -name "*.tar.gz" -type f | sort | head -1 | xargs rm
+```
+
+**Verification**:
+```bash
+df -h  # Should be <80% now
+du -sh backups/
+```
+
+**Prevention**: Increase disk size or set up offsite backups
+
+---
+
+### INCIDENT 5: Data Corruption (10 min recovery target)
+
+**Detection**: Database integrity check fails, unexpected data missing, query errors
+
+**Immediate (1 minute)**:
+```bash
+# Verify corruption
+docker-compose exec backend sqlite3 /app/data/inventory.db "PRAGMA integrity_check;"
+# OR (Standalone)
+sqlite3 data/inventory.db "PRAGMA integrity_check;"
+
+# Check logs for errors
+docker-compose logs backend | grep -i "error" | tail -20
+```
+
+**Recovery (8-10 minutes)**:
+```bash
+# CRITICAL: Do not attempt to repair
+# Restore from backup (fastest, safest option)
+
+# 1. Check available backups
+ls -lh backups/ | head -5
+
+# 2. Stop services
+docker-compose down  # Docker
+pkill -f uvicorn  # Standalone
+
+# 3. Restore
+./scripts/restore.sh backups/latest.tar.gz --validate
+
+# 4. Restart (if needed)
+docker-compose up -d  # Docker
+./start_server.sh  # Standalone
+
+# 5. Verify
+curl http://localhost:8000/health
+```
+
+**Notify Users**: Data loss = up to 1 day (latest backup)
+
+**Escalate**: Call database admin after recovery
+
+---
+
+### INCIDENT 6: Network / CORS Errors (5 min recovery target)
+
+**Detection**: Browser console shows CORS error, frontend can't reach backend
+
+**Immediate (1 minute)**:
+```bash
+# Test backend connectivity
+curl -v http://localhost:8000/health
+curl -v http://<server-ip>:8000/health
+
+# Check CORS configuration
+docker-compose exec backend python -c "
+from backend.config import ALLOWED_ORIGINS
+print('ALLOWED_ORIGINS:', ALLOWED_ORIGINS)
+"
+```
+
+**Recovery**:
+```bash
+# 1. Check network connectivity
+ping <backend-server-ip>
+
+# 2. Update CORS if needed
+# Edit inventory.env:
+EXTRA_ALLOWED_ORIGINS=<client-ip>
+
+# 3. Restart backend
+docker-compose restart backend
+
+# 4. Test
+curl -H "Origin: http://<client-ip>" -v http://localhost:8000/health
+```
+
+**Verify**: Frontend should load without CORS errors
+
+---
+
+### INCIDENT 7: Frontend Not Loading (5 min recovery target)
+
+**Detection**: Frontend port doesn't respond, blank page, 404 errors
+
+**Recovery (Docker)**:
+```bash
+# Check service
+docker-compose ps | grep frontend
+
+# Restart
+docker-compose restart frontend
+
+# Check logs
+docker-compose logs frontend | tail -50
+
+# If build failed, rebuild
+docker-compose down
+docker-compose up -d --build
+```
+
+**Recovery (Standalone)**:
+```bash
+# Kill process
+pkill -f "next start"
+
+# Rebuild if needed
+cd frontend && npm install && npm run build
+
+# Restart
+cd .. && npm start --prefix frontend &
+```
+
+---

+# Health Monitoring Checklist
+
+Use this checklist for daily/weekly health reviews. Adapt commands for Docker or Standalone mode as needed.
+
+---
+
+## Daily Checks (5 minutes)
+
+Print this section and post near the server or set email reminders.
+
+- [ ] **All services running**
+  - Docker: `docker-compose ps` (expect: All "Up")
+  - Standalone: `ps aux | grep -E "(uvicorn|next)" | grep -v grep` (expect: 2 processes)
+
+- [ ] **API responsive**
+  - `curl -w "\nHTTP %{http_code}\n" http://localhost:8000/health`
+  - Expected: 200 OK, response <100ms
+
+- [ ] **Frontend loads**
+  - `curl -w "\nHTTP %{http_code}\n" http://localhost:3000`
+  - Expected: 200 OK
+
+- [ ] **Recent errors in logs**
+  - Docker: `docker-compose logs | grep ERROR | tail -5`
+  - Standalone: `tail -20 logs/*.log | grep ERROR`
+  - Action: Investigate any ERROR-level logs
+
+- [ ] **Database accessible**
+  - Docker: `docker-compose exec backend sqlite3 /app/data/inventory.db "SELECT COUNT(*) FROM items;"`
+  - Standalone: `sqlite3 data/inventory.db "SELECT COUNT(*) FROM items;"`
+  - Action: If fails, restart backend service
+
+---
+
+## Weekly Checks (15 minutes)
+
+- [ ] **Backup completed**
+  - `ls -lh backups/ | head -1`
+  - Check timestamp is within last 24 hours
+  - Action: Manual backup if needed: `./scripts/backup.sh manual`
+
+- [ ] **Disk usage within limits**
+  - `du -sh data/ config/ backups/`
+  - Expected: data/ <5GB, backups/ <10GB
+  - Action: If backups >10GB, verify cron retention settings
+
+- [ ] **Database size reasonable**
+  - `du -h data/inventory.db`
+  - Action: If >1GB, consider optimization (vacuum/index)
+
+- [ ] **Service resource usage**
+  - Docker: `docker stats --no-stream`
+  - Standalone: `ps aux | grep -E "(uvicorn|next)"`
+  - Expected: Backend <70% CPU, <500MB RAM
+
+- [ ] **Log files not growing excessively**
+  - `ls -lh logs/ | tail -10`
+  - Action: If any log >100MB, consider rotation
+
+- [ ] **Check for hung processes**
+  - `ps aux | grep -E "(defunct|defunct)"` (should be empty)
+  - Action: Kill hung processes
+
+---
+
+## Monthly Checks (30 minutes)
+
+- [ ] **Restore from backup test**
+  - On staging environment:
+    ```bash
+    ./scripts/restore.sh backups/latest.tar.gz --validate
+    ```
+  - Confirm zero data loss, all services healthy
+  - Action: If fails, investigate and fix immediately
+
+- [ ] **Scaling capacity review**
+  - Current: Single instance, 5 concurrent users stable
+  - Actual usage: _____ concurrent users
+  - Action: If approaching 5 users, plan for v3 multi-instance
+
+- [ ] **Security audit**
+  - [ ] JWT_SECRET_KEY still secure (not exposed in logs)
+  - [ ] LDAP credentials (if used) still valid
+  - [ ] API logs show no unauthorized access attempts
+  - Check: `docker-compose logs backend | grep -i "denied\|failed\|unauthorized" | tail -20`
+
+- [ ] **Documentation review**
+  - [ ] Runbook matches current deployment
+  - [ ] Troubleshooting section covers recent issues
+  - [ ] Contact info still current
+
+---
+
+## Alert Thresholds
+
+| Metric | Warning | Critical | Action |
+|--------|---------|----------|--------|
+| CPU (backend) | >50% | >70% | Restart container, investigate slow queries |
+| Memory (backend) | >400MB | >600MB | Restart container, check for memory leak |
+| Disk (backups) | >10GB | >15GB | Delete old backups, increase retention |
+| API response (p95) | >500ms | >1s | Check slow query logs, restart backend |
+| Backup age | >36 hours | >48 hours | Manual run needed, check cron |
+| Database locked | 1 event/week | 5+ events/week | Investigate, may need v3 upgrade |
+| Error rate | >0.1% | >1% | Investigate logs, restart if needed |
+
+---
+
+## Quick Troubleshooting Reference
+
+**Service down?**
+→ `docker-compose ps` or `ps aux | grep uvicorn`
+→ `docker-compose logs SERVICE_NAME` or `tail logs/*.log`
+→ `docker-compose restart SERVICE_NAME` or `pkill -f uvicorn`
+
+**Slow responses?**
+→ `docker stats` or `ps aux | grep uvicorn`
+→ `docker-compose logs backend | grep "slow"` or check logs
+→ Restart backend or plan for capacity increase
+
+**Database locked?**
+→ Restart backend: `docker-compose restart backend`
+
+**Out of disk space?**
+→ `du -sh data/ backups/`
+→ Clean old backups: `find backups/ -name "*.tar.gz" -mtime +30 -delete`
+→ Extend volume if needed
+
+**HTTPS certificate issues?**
+→ `rm -rf data/caddy_*` (Docker mode)
+→ `docker-compose restart proxy`
+→ Wait 30 seconds for new certs to generate

+# Operational Runbook
+
+**Audience**: Systems operators, site managers, DevOps teams  
+**Target**: Minimal training required; step-by-step procedures  
+**Last Updated**: 2026-04-22
+
+---
+
+## Overview
+
+This runbook covers operational procedures for both Docker and Standalone deployment modes. Both modes use the same configuration files (inventory.env) and backup/restore scripts.
+
+---
+
+## 1. Initial Deployment
+
+### Requirements
+
+- Ubuntu 22.04 LTS or similar
+- For Docker mode: Docker and Docker Compose installed
+- For Standalone mode: Python 3.12+, Node.js 18+, npm
+- 2GB RAM minimum, 10GB disk (recommended: 4GB/50GB for production)
+- Internet access (first-time setup only)
+
+### Docker Deployment Steps
+
+1. **Clone repository**
+   ```bash
+   git clone <repo_url> /opt/tfm-inventory
+   cd /opt/tfm-inventory
+   ```
+
+2. **Configure environment**
+   ```bash
+   cp inventory.env.template inventory.env
+   # Edit inventory.env with your settings:
+   # - BACKEND_PORT=8000, FRONTEND_PORT=3000
+   # - JWT_SECRET_KEY (generate: openssl rand -hex 32)
+   # - AI settings (Gemini/Claude API keys, optional)
+   # - LDAP settings (if using enterprise auth)
+   ```
+
+3. **Deploy**
+   ```bash
+   chmod +x deploy.sh scripts/backup.sh scripts/restore.sh
+   ./deploy.sh production
+   ```
+
+4. **Verify deployment**
+   - Frontend: http://your-server:3000
+   - Backend API: http://your-server:8000
+   - API Docs: http://your-server:8000/docs
+   - Health check: `curl http://localhost:8000/health`
+
+5. **Create admin user** (if not auto-created)
+   ```bash
+   docker-compose exec backend python -c "
+   from backend.db import SessionLocal, User
+   db = SessionLocal()
+   user = User(username='admin', hashed_password='...', is_admin=True)
+   db.add(user)
+   db.commit()
+   "
+   ```
+
+### Standalone Deployment Steps
+
+1. **Clone repository**
+   ```bash
+   git clone <repo_url> /opt/tfm-inventory
+   cd /opt/tfm-inventory
+   ```
+
+2. **Configure environment**
+   ```bash
+   cp inventory.env.template inventory.env
+   # Edit with same settings as Docker mode
+   ```
+
+3. **Install dependencies**
+   ```bash
+   # Backend
+   cd backend
+   python3 -m venv venv
+   source venv/bin/activate
+   pip install -r requirements.txt
+   cd ..
+
+   # Frontend
+   cd frontend
+   npm install
+   cd ..
+   ```
+
+4. **Deploy**
+   ```bash
+   chmod +x start_server.sh scripts/backup.sh scripts/restore.sh
+   ./start_server.sh
+   ```
+
+5. **Verify deployment**
+   - Frontend: http://localhost:3000
+   - Backend API: http://localhost:8000
+   - Health check: `curl http://localhost:8000/health`
+
+---
+
+## 2. Daily Operations
+
+### Health Checks (Daily, ~5 minutes)
+
+**Docker mode:**
+```bash
+# Check all services
+docker-compose ps
+# Expected: All services "Up"
+
+# Check API health
+curl http://localhost:8000/health
+# Expected: 200 OK, response time <100ms
+
+# Check database
+du -h data/inventory.db
+
+# Check for errors
+docker-compose logs | grep ERROR | tail -5
+```
+
+**Standalone mode:**
+```bash
+# Check processes
+ps aux | grep -E "(uvicorn|next)" | grep -v grep
+
+# Check API health
+curl http://localhost:8000/health
+
+# Check database
+du -h data/inventory.db
+
+# Check logs
+tail -50 logs/backend.log logs/frontend.log 2>/dev/null
+```
+
+### Backup (Automated)
+
+```bash
+# Verify automatic backup ran (cron jobs)
+ls -lh backups/ | head -1
+# Expected: File timestamp within last 24 hours
+
+# Manual backup (if needed)
+./scripts/backup.sh manual
+
+# View backup schedule
+sudo crontab -l | grep backup
+```
+
+### Monitoring
+
+**Docker mode:**
+```bash
+# Real-time logs
+docker-compose logs -f
+
+# Backend performance
+docker stats --no-stream | grep backend
+
+# Database status
+docker-compose exec backend sqlite3 /app/data/inventory.db \
+  "SELECT COUNT(*) as item_count, SUM(quantity) as total_qty FROM items;"
+```
+
+**Standalone mode:**
+```bash
+# Real-time logs
+tail -f logs/backend.log logs/frontend.log
+
+# System resources
+top -p $(pgrep -f uvicorn | head -1)
+
+# Database status
+sqlite3 data/inventory.db \
+  "SELECT COUNT(*) as item_count, SUM(quantity) as total_qty FROM items;"
+```
+
+---
+
+## 3. Troubleshooting
+
+### Service Won't Start
+
+**Docker mode:**
+```bash
+# Check Docker daemon
+docker ps
+
+# Check port conflicts
+netstat -tuln | grep -E "8000|3000|8906|8907"
+
+# View service logs
+docker-compose logs backend
+docker-compose logs frontend
+docker-compose logs proxy
+```
+
+**Standalone mode:**
+```bash
+# Check if processes are running
+ps aux | grep -E "(uvicorn|next)"
+
+# Check port conflicts
+netstat -tuln | grep -E "8000|3000"
+
+# Check logs
+cat logs/backend.log | tail -50
+```
+
+### High CPU/Memory
+
+**Docker mode:**
+```bash
+# Identify container
+docker stats --no-stream
+
+# Restart container
+docker-compose restart backend
+
+# Check for slow queries
+docker-compose logs backend | grep "slow"
+```
+
+**Standalone mode:**
+```bash
+# Kill and restart
+pkill -f uvicorn
+pkill -f "next start"
+sleep 2
+./start_server.sh
+```
+
+### Database Locked
+
+**Docker mode:**
+```bash
+docker-compose restart backend
+# Wait 30 seconds
+docker-compose exec backend sqlite3 /app/data/inventory.db "PRAGMA journal_mode;"
+```
+
+**Standalone mode:**
+```bash
+pkill -f uvicorn
+sleep 2
+# Restart backend only (no need for frontend restart)
+cd backend && source venv/bin/activate && uvicorn main:app --host 0.0.0.0 --port 8000 &
+```
+
+### HTTPS Certificate Issues
+
+**Docker mode:**
+```bash
+# Certificates regenerated automatically
+# If issues persist:
+rm -rf data/caddy_*
+docker-compose restart proxy
+# Wait 30 seconds for new certs to generate
+```
+
+**Standalone mode:**
+```bash
+# For local development/testing, HTTP is sufficient
+# For production HTTPS, configure reverse proxy (nginx/Caddy) separately
+```
+
+---
+
+## 4. Backup & Restore
+
+### Automated Backups
+
+```bash
+# Verify cron jobs are installed
+sudo bash config/backup-cron.sh
+
+# View backup history
+ls -lh backups/
+
+# Check backup log
+tail -20 logs/backup-daily.log
+```
+
+**Backup Schedule:**
+- Daily: 2 AM, retention 30 days
+- Weekly: 3 AM Sundays, retention 90 days
+
+### Manual Backup
+
+```bash
+# Create backup
+./scripts/backup.sh manual
+
+# Verify backup created and is valid
+tar -tzf backups/inventory-*.tar.gz | head
+```
+
+### Manual Restore
+
+```bash
+# List available backups
+ls backups/
+
+# Restore specific backup (Docker mode)
+./scripts/restore.sh backups/inventory-2026-04-22_14-30-15.tar.gz --validate
+
+# Restore specific backup (Standalone mode)
+./scripts/restore.sh backups/inventory-2026-04-22_14-30-15.tar.gz
+# Then restart: ./start_server.sh
+
+# Validate data after restore
+curl http://localhost:8000/health
+```
+
+**Recovery Objectives:**
+- RTO (Recovery Time): <10 minutes
+- RPO (Recovery Point): 1 day (daily backup)
+
+---
+
+## 5. Disaster Recovery
+
+### Complete System Failure (Hardware or Data Corruption)
+
+**For Docker:**
+1. Provision new Ubuntu 22.04 LTS server (same specs)
+2. Clone repository: `git clone <repo> /opt/tfm-inventory && cd /opt/tfm-inventory`
+3. Copy latest backup from offsite or previous backup directory
+4. Restore: `./scripts/restore.sh /path/to/backup.tar.gz --validate`
+5. Update DNS/load balancer to new server IP
+6. Verify all services healthy and data present
+
+**For Standalone:**
+1. Provision new Ubuntu 22.04 LTS server
+2. Clone repository
+3. Install dependencies (Python venv, Node.js)
+4. Copy latest backup
+5. Restore: `./scripts/restore.sh /path/to/backup.tar.gz`
+6. Start services: `./start_server.sh`
+7. Verify connectivity and data
+
+**RTO**: <30 minutes (provisioning + restore)  
+**RPO**: 1 day (latest backup)
+
+### Data Center Failure
+
+1. Activate secondary site or failover to cloud
+2. Clone repository on new infrastructure
+3. Restore latest backup: `./scripts/restore.sh backup.tar.gz --validate`
+4. Update DNS to new location
+5. Notify users of recovery (1-day data loss acceptable)
+
+---
+
+## 6. Scaling Operations
+
+### Adding Users (5+ concurrent)
+
+Current configuration supports 5 concurrent users safely.
+
+**Docker mode:**
+```bash
+# Increase backend memory
+# Edit docker-compose.yml:
+# backend:
+#   mem_limit: 4g
+
+# Increase database connections
+docker-compose exec backend \
+  python -c "import backend.config; print(backend.config.DB_POOL_SIZE)"
+```
+
+**Standalone mode:**
+```bash
+# Increase Python process resources
+# Edit start_server.sh to add workers/processes if using Gunicorn
+
+# Monitor memory usage
+ps aux | grep uvicorn
+```
+
+### Database Growth (10K+ items)
+
+As inventory grows beyond 10K items:
+1. Monitor query performance: `PRAGMA optimize;`
+2. Create indexes on frequently searched columns
+3. Vacuum database: `VACUUM;`
+4. Consider archiving old audit logs (v3 feature)
+
+---
+
+## 7. Updates & Upgrades
+
+### Patch Update (v1.14.x → v1.14.y)
+
+```bash
+# Backup first
+./scripts/backup.sh manual
+
+# Pull latest code
+git pull origin main
+
+# Docker mode:
+./deploy.sh production --rebuild
+
+# Standalone mode:
+pkill -f uvicorn
+pkill -f "next start"
+cd backend && source venv/bin/activate && pip install -r requirements.txt
+cd ../frontend && npm install && npm run build
+./start_server.sh
+
+# Verify
+curl http://localhost:8000/health
+```
+
+### Major Update (v1.x → v2.x)
+
+```bash
+# Create backup before proceeding
+./scripts/backup.sh manual
+
+# Review CHANGELOG for breaking changes
+cat CHANGELOG.md | grep "v2.0"
+
+# Test in staging first (restore backup there)
+./scripts/restore.sh backups/production.tar.gz
+
+# If staging successful, proceed to production
+git checkout v2.0
+./deploy.sh production --rebuild  # Docker mode
+# OR
+./start_server.sh  # Standalone mode
+```
+
+---
+
+## 8. Performance Baseline
+
+- Backend: <100ms API response time at 5 concurrent users
+- Frontend: <1s page load
+- Database: <500 queries/min with 10K items
+- Memory: Backend <500MB, Frontend <200MB
+- CPU: Both services <70% usage under normal load
+
