PhoenixShield 🔥🛡️

> *"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:**

---

Quick Start

1. Initialize PhoenixShield

```bash

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

```

2. Create Pre-Update Snapshot

```bash

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

```

3. Safe Update with Auto-Recovery

```bash

phoenix-shield update \

--command "npm update" \

--health-check "curl -f http://localhost/health" \

--auto-rollback

```

4. Monitor Post-Update

```bash

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

```

---

Core Features

1. Pre-Flight Checks

Before any update, PhoenixShield verifies:

```bash

phoenix-shield preflight

```

**Checks:**

2. Intelligent Backup

```bash

Full system snapshot

phoenix-shield backup --full

Incremental (only changed files)

phoenix-shield backup --incremental

Config-only backup

phoenix-shield backup --config

```

**Backup includes:**

3. Canary Deployment

Test updates on isolated environment first:

```bash

phoenix-shield canary \

--command "apt upgrade" \

--test-duration 5m \

--test-command "systemctl status nginx"

```

4. Production Update

Execute update with safety net:

```bash

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 |

```bash

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

```bash

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

```bash

#!/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

```bash

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

```bash

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`:

```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

```yaml

GitHub Actions example

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

```bash

Bad

phoenix-shield deploy --command "apt upgrade"

Good

phoenix-shield preflight && \

phoenix-shield deploy --command "apt upgrade"

```

2. Test Rollback Before Production

```bash

phoenix-shield snapshot --name test

phoenix-shield deploy --command "echo test"

phoenix-shield rollback --dry-run # See what would happen

```

3. Monitor Critical Updates

```bash

phoenix-shield deploy --command "major-update.sh"

phoenix-shield monitor --duration 48h # Extended monitoring

```

4. Maintain Backup Hygiene

```bash

Regular cleanup

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

Verify backups

phoenix-shield verify --all

```

---

Troubleshooting

"Preflight check failed"

"Rollback failed"

"Health checks failing"
