# IGNY8 Application Packaging & Backup - Setup Complete ✅

## What Was Created

### 1. Packaging Script
**File**: `/data/app/igny8/scripts/package_app.sh`
- ✅ Creates portable application packages
- ✅ Excludes all generated artifacts (node_modules, .venv, dist, logs, etc.)
- ✅ Generates SHA256 checksums for verification
- ✅ Auto-cleans old backups (7+ days)
- ✅ Package size: ~44 MB (compressed from ~56 MB source)

### 2. Automated Backup Tasks
**File**: `/data/app/igny8/backend/igny8_core/tasks/backup.py`
- ✅ `backup.create_daily_app_package` - Daily backup task
- ✅ `backup.cleanup_old_packages` - Weekly cleanup task
- ✅ Full error handling and logging

### 3. Celery Beat Schedule
**File**: `/data/app/igny8/backend/igny8_core/celery.py`
- ✅ Daily backup at 00:00 UTC
- ✅ Weekly cleanup on Mondays at 01:00 UTC

### 4. Documentation
- ✅ `/data/app/igny8/INSTALLATION.md` - Complete installation guide
- ✅ `/data/app/igny8/docs/BACKUP-SYSTEM.md` - Backup system documentation

## First Backup Created

```
📦 Package: /data/backups/igny8/igny8-app-20251210_161527.tar.gz
📏 Size: 44 MB
🔐 SHA256: 5aa8fe458bcb75d1f4a455746a484015a81147bbfa8e8b1285e99195e2deacbd
```

## How It Works

### Automatic Daily Backups (00:00 UTC)
1. Celery Beat triggers `backup.create_daily_app_package` at midnight
2. Task executes `/data/app/igny8/scripts/package_app.sh`
3. Script creates compressed archive with date stamp
4. Package saved to `/data/backups/igny8/`
5. SHA256 checksum file generated
6. Old backups (7+ days) auto-deleted

### What Gets Packaged
**INCLUDED** (~56 MB source):
- `backend/igny8_core/` - All Django code
- `backend/manage.py`, `requirements.txt`
- `frontend/src/`, `public/` - All React code
- `frontend/package.json`, build configs
- `docs/`, `README.md`
- Dockerfiles, docker-compose files

**EXCLUDED** (auto-generated):
- `node_modules/` - NPM dependencies (297 MB)
- `.venv/` - Python virtual environment (140 MB)
- `dist/` - Build outputs
- `*.sql`, `*.sqlite3` - Databases
- `logs/` - Runtime logs
- Cache files, compiled files

### Restoration Process
```bash
# On new server:
1. Extract: tar -xzf igny8-app-YYYYMMDD_HHMMSS.tar.gz
2. Verify: sha256sum -c igny8-app-YYYYMMDD_HHMMSS.tar.gz.sha256
3. Follow INSTALLATION.md to deploy
```

## Testing & Verification

### Manual Test (Already Done ✅)
```bash
/data/app/igny8/scripts/package_app.sh
# Result: Package created successfully at /data/backups/igny8/
```

### Verify Celery Tasks
```bash
# Restart Celery to load new tasks
docker restart igny8_celery_worker igny8_celery_beat

# Check scheduled tasks
docker exec igny8_celery_beat celery -A igny8_core inspect scheduled

# View Beat logs
docker logs igny8_celery_beat

# Manually trigger backup (for testing)
docker exec igny8_celery_worker celery -A igny8_core call backup.create_daily_app_package
```

### Monitor Backups
```bash
# List all backups
ls -lh /data/backups/igny8/

# Check latest backup
ls -lt /data/backups/igny8/ | head -3

# Verify checksum
cd /data/backups/igny8/
sha256sum -c igny8-app-*.tar.gz.sha256
```

## Next Steps

1. **Wait for first automated backup** (will run at 00:00 UTC tonight)
2. **Verify backup runs successfully**:
   ```bash
   # Check tomorrow morning
   ls -lt /data/backups/igny8/
   ```
3. **Optional: Add remote backup** (copy to S3, Google Drive, etc.)

## Retention Policy

- **Packaging script**: Deletes backups > 7 days old
- **Cleanup task**: Deletes backups > 30 days old (weekly check)
- **Result**: 7-30 days of backups retained automatically

## Package Portability

✅ **Portable** - Package contains only source code
✅ **Small** - 44 MB compressed (vs ~500+ MB with dependencies)
✅ **Clean** - No generated files, logs, or secrets
✅ **Verified** - SHA256 checksum ensures integrity
✅ **Self-contained** - Everything needed to rebuild app

## Deployment to New Server

From the package, you get a clean IGNY8 installation:

1. Extract package (44 MB)
2. Install Docker
3. Build images (Docker installs dependencies automatically)
4. Start services
5. Initialize database
6. **Ready to run!**

**Dependencies installed automatically by Docker**:
- Python packages from `requirements.txt`
- Node packages from `package.json`
- PostgreSQL, Redis containers
- All build tools and dependencies

## Summary

✅ **Automated daily backups** at midnight
✅ **Portable packages** - only source code
✅ **Auto-cleanup** - keeps 7-30 days
✅ **Checksum verification** - ensures integrity
✅ **Easy restoration** - extract and deploy
✅ **Documentation** - complete guides created

**Total disk usage for backups**: ~44 MB × 7-30 days = **308 MB - 1.3 GB**

Much better than storing everything (would be 10+ GB with node_modules, venv, etc.)!
