./scripts/backup-models.sh

# Verify model checksums
sha256sum models/* > models.checksums

Restore Procedures¶

Database Restore:

cat backup.sql | docker-compose exec -T supabase-db psql -U postgres

# Restore Vector DB
./scripts/restore-qdrant.sh backup_file

Configuration Restore:

# Restore env files
cp .env.backup .env

# Restore configurations
tar -xzf config-backup.tar.gz

System Updates¶

Service Updates¶

Pre-update Checks:

# Check service status
docker-compose ps

# Create backup
./scripts/backup.sh pre-update

Update Process:

# Pull updates
docker-compose pull

# Apply updates
docker-compose up -d

# Verify update
docker-compose ps

Post-update Tasks:

# Check logs for errors
docker-compose logs --tail=100

# Run tests
./scripts/test-services.sh

Security Updates¶

Update Security Rules:

# Update AI Guardian rules
./scripts/update-ai-guardian.sh

# Update firewall rules
./scripts/update-firewall.sh

Apply Security Patches:

# System updates
apt update && apt upgrade -y

# Container updates
docker-compose pull

Performance Optimization¶

Resource Management¶

Monitor Resources:

# Check CPU usage
top -b -n 1

# Check memory
free -h

# Check disk space
df -h

Optimize Storage:

# Clean Docker
docker system prune -a

# Clean old logs
find logs/ -name "*.log" -mtime +30 -delete

Database Optimization¶

Database Maintenance:

# Vacuum database
docker-compose exec supabase-db vacuumdb -U postgres -z

# Analyze tables
docker-compose exec supabase-db analyzedb -U postgres

Index Optimization:

# Reindex database
docker-compose exec supabase-db reindexdb -U postgres

Monitoring Setup¶

System Monitoring¶

Configure Prometheus:

# prometheus/config/monitoring.yml
scrape_configs:
  - job_name: 'system'
    static_configs:
      - targets: ['localhost:9100']

Setup Alerts:

# prometheus/config/alerts.yml
groups:
  - name: system
    rules:
      - alert: HighCPUUsage
        expr: cpu_usage > 80

Log Management¶

Configure Log Rotation:

# Setup logrotate
cat > /etc/logrotate.d/local-ai-cyber-lab << EOF
/var/log/local-ai-cyber-lab/*.log {
    daily
    rotate 7
    compress
}
EOF

Setup Log Aggregation:

# Configure log shipping
./scripts/setup-log-shipping.sh

Emergency Procedures¶

Service Recovery¶

Stop Services:
```
docker-compose down
```
Backup Data:
```
./scripts/emergency-backup.sh
```
Reset State:
```
docker system prune -a
```
Restore Services:
```
docker-compose up -d
```

Data Recovery¶

Identify Issue:

# Check logs
docker-compose logs --tail=1000

# Check disk space
df -h

Restore Data:

# Restore from backup
./scripts/restore.sh latest

# Verify restoration
./scripts/verify-restore.sh
