"Like the Phoenix, your system rises from its own backup"

Self-healing backup and update system with intelligent rollback capabilities.

Why PhoenixShield?

Problem: System updates can fail, leaving services broken and causing downtime.

Solution: PhoenixShield provides a complete safety net with automatic rollback when things go wrong.

Benefits:

• 🔄 Automatic Recovery - Self-heals when updates fail
• 🧪 Canary Testing - Test updates before production
• 📊 Health Monitoring - 24h post-update monitoring
• ⚡ Smart Rollback - Only revert changed components
• 🛡️ Zero-Downtime - Graceful degradation when possible

---

Quick Start

1. Initialize PhoenixShield

phoenix-shield init --project myapp --backup-dir /var/backups

2. Create Pre-Update Snapshot

phoenix-shield snapshot --name "pre-update-$(date +%Y%m%d)"

3. Safe Update with Auto-Recovery

phoenix-shield update \
  --command "npm update" \
  --health-check "curl -f http://localhost/health" \
  --auto-rollback

4. Monitor Post-Update

phoenix-shield monitor --duration 24h --interval 5m

---

Core Features

1. Pre-Flight Checks

Before any update, PhoenixShield verifies:

phoenix-shield preflight

Checks:

• ✅ Disk space available
• ✅ No critical processes running
• ✅ Backup storage accessible
• ✅ Network connectivity
• ✅ Service health baseline

2. Intelligent Backup

# Full system snapshot
phoenix-shield backup --full

# Incremental (only changed files)
phoenix-shield backup --incremental

# Config-only backup
phoenix-shield backup --config

Backup includes:

• Configuration files
• Database dumps
• System state
• Process list
• Network connections
• Health metrics baseline

3. Canary Deployment

Test updates on isolated environment first:

phoenix-shield canary \
  --command "apt upgrade" \
  --test-duration 5m \
  --test-command "systemctl status nginx"

4. Production Update

Execute update with safety net:

phoenix-shield deploy \
  --command "npm install -g openclaw@latest" \
  --health-checks "openclaw --version" \
  --health-checks "openclaw health" \
  --rollback-on-failure

5. Post-Update Monitoring

Automatic monitoring stages:

| Timeframe | Checks |

|-----------|--------|

| 0-5 min | Critical services running |

| 5-30 min | All services responding |

| 30-120 min | Integration tests |

| 2-24h | Stability monitoring |

phoenix-shield monitor --start

6. Smart Rollback

When update fails, PhoenixShield:

1. Attempts soft recovery - Restart services
2. Config rollback - Revert configuration
3. Package rollback - Downgrade packages
4. Full restore - Complete system restore
5. Emergency mode - Minimal services, notify admin

# Manual rollback
phoenix-shield rollback --to-snapshot "pre-update-20260205"

# Check what would be rolled back (dry run)
phoenix-shield rollback --dry-run

---

Workflow Examples

Safe OpenClaw Update

#!/bin/bash
# Update OpenClaw with PhoenixShield protection

phoenix-shield preflight || exit 1

phoenix-shield snapshot --name "openclaw-$(date +%Y%m%d)"

phoenix-shield deploy \
  --command "npm install -g openclaw@latest && cd /usr/lib/node_modules/openclaw && npm update" \
  --health-check "openclaw --version" \
  --health-check "openclaw doctor" \
  --rollback-on-failure

phoenix-shield monitor --duration 2h

Ubuntu Server Update

phoenix-shield deploy \
  --command "apt update && apt upgrade -y" \
  --health-check "systemctl status nginx" \
  --health-check "systemctl status mysql" \
  --pre-hook "/root/notify-start.sh" \
  --post-hook "/root/notify-complete.sh" \
  --auto-rollback

Multi-Server Update

# Update multiple servers with PhoenixShield
SERVERS="server1 server2 server3"

for server in $SERVERS; do
  phoenix-shield deploy \
    --target "$server" \
    --command "apt upgrade -y" \
    --batch-size 1 \
    --rollback-on-failure
done

---

Configuration

Create phoenix-shield.yaml:

project: my-production-app
backup:
  directory: /var/backups/phoenix
  retention: 10  # Keep last 10 backups
  compression: gzip

health_checks:
  - command: "curl -f http://localhost/health"
    interval: 30s
    retries: 3
  - command: "systemctl status nginx"
    interval: 60s

monitoring:
  enabled: true
  duration: 24h
  intervals:
    critical: 1m    # 0-5 min
    normal: 5m      # 5-30 min
    extended: 30m   # 30-120 min
    stability: 2h   # 2-24h

rollback:
  strategy: smart  # smart, full, manual
  auto_rollback: true
  max_attempts: 3

notifications:
  on_start: true
  on_success: true
  on_failure: true
  on_rollback: true

Integration with CI/CD

# GitHub Actions example
- name: Safe Deployment
  run: |
    phoenix-shield preflight
    phoenix-shield snapshot --name "deploy-$GITHUB_SHA"
    phoenix-shield deploy \
      --command "./deploy.sh" \
      --health-check "curl -f http://localhost/ready" \
      --auto-rollback

---

Best Practices

1. Always Use Preflight

# Bad
phoenix-shield deploy --command "apt upgrade"

# Good
phoenix-shield preflight && \
phoenix-shield deploy --command "apt upgrade"

2. Test Rollback Before Production

phoenix-shield snapshot --name test
phoenix-shield deploy --command "echo test"
phoenix-shield rollback --dry-run  # See what would happen

3. Monitor Critical Updates

phoenix-shield deploy --command "major-update.sh"
phoenix-shield monitor --duration 48h  # Extended monitoring

4. Maintain Backup Hygiene

# Regular cleanup
phoenix-shield cleanup --keep-last 10 --older-than 30d

# Verify backups
phoenix-shield verify --all

---

Troubleshooting

"Preflight check failed"

• Check disk space: df -h
• Verify backup location exists
• Ensure no critical processes running

"Rollback failed"

• Check backup integrity: phoenix-shield verify
• Manual restore from: /var/backups/phoenix/
• Contact admin for emergency recovery

"Health checks failing"

• Extend monitoring: phoenix-shield monitor --duration 48h
• Check service logs: journalctl -u myservice
• Consider partial rollback: phoenix-shield rollback --config-only
