# QR Code Manager - Backup System
The QR Code Manager includes a comprehensive backup system to protect your data and ensure business continuity. This document explains how to use the backup features effectively.
## 📋 Overview
The backup system provides three types of backups:
- **Data Backup** 📄: QR codes, link pages, and short URLs (recommended for regular backups)
- **Config Backup** ⚙️: Configuration files and environment settings
- **Full Backup** 📦: Complete application backup including all files
## 🛠️ Backup Methods
### 1. Web Interface (Recommended)
Access the backup management interface through the main dashboard:
1. Login to your QR Code Manager
2. Click the "🛡️ Backup" button in the top-right corner
3. Use the web interface to create, download, and manage backups
**Features:**
- Visual backup status dashboard
- One-click backup creation
- Direct backup downloads
- Backup history and file sizes
### 2. Python Script
Use the dedicated backup script for command-line operations:
```bash
# Data backup (default)
python3 backup.py
# Specific backup types
python3 backup.py --data-only
python3 backup.py --config
python3 backup.py --full
# List available backups
python3 backup.py --list
# Restore from backup
python3 backup.py --restore backup_file.tar.gz
# Automated backup (for cron)
python3 backup.py --auto
# Cleanup old backups
python3 backup.py --cleanup 10
```
### 3. Docker Script
For Docker deployments, use the Docker-specific backup script:
```bash
# Make script executable
chmod +x docker_backup.sh
# Data backup
./docker_backup.sh backup-data
# Full backup
./docker_backup.sh backup-full
# List backups
./docker_backup.sh list
# Restore from backup
./docker_backup.sh restore backup_file.tar.gz
# Cleanup old backups
./docker_backup.sh cleanup 5
# Set up automated backups
./docker_backup.sh schedule
```
## ⏰ Automated Backups
### Using Cron (Linux/macOS)
1. Set up automated backups:
```bash
./docker_backup.sh schedule
```
2. Or manually add to crontab (`crontab -e`):
```bash
# Daily data backup at 2 AM
0 2 * * * /path/to/qr-code_manager/docker_backup.sh backup-data >> /path/to/backup.log 2>&1
# Weekly full backup on Sundays at 3 AM
0 3 * * 0 /path/to/qr-code_manager/docker_backup.sh backup-full >> /path/to/backup.log 2>&1
```
### Using Python Auto Mode
The Python script includes an intelligent auto mode:
```bash
# Add to cron for smart automated backups
0 2 * * * cd /path/to/qr-code_manager && python3 backup.py --auto >> backup.log 2>&1
```
**Auto mode behavior:**
- Daily: Data backup
- Monday: Data + Config backup
- 1st of month: Data + Config + Full backup
- Automatic cleanup of old backups
## 📁 Backup Storage
### Default Location
All backups are stored in the `backups/` directory within your QR Code Manager installation.
### Backup Files
- **Data backups**: `qr_data_backup_YYYYMMDD_HHMMSS.tar.gz`
- **Config backups**: `qr_config_backup_YYYYMMDD_HHMMSS.tar.gz`
- **Full backups**: `qr_full_backup_YYYYMMDD_HHMMSS.tar.gz`
### Metadata Files
Each backup includes a JSON metadata file with:
- Backup type and timestamp
- Application version
- File list and sizes
- Backup method used
## 🔄 Restore Process
### Web Interface Restore
Currently, the web interface provides backup download. For restoration:
1. Download the desired backup file
2. Use command-line restore methods below
### Command Line Restore
```bash
# Python script restore
python3 backup.py --restore backup_file.tar.gz
# Docker script restore
./docker_backup.sh restore backup_file.tar.gz
```
### Manual Restore
1. Stop the application:
```bash
docker compose down
```
2. Backup current data (safety):
```bash
mv data data.backup.$(date +%Y%m%d_%H%M%S)
```
3. Extract backup:
```bash
tar xzf backup_file.tar.gz
```
4. Restart application:
```bash
docker compose up -d
```
## 🔐 Security Considerations
### Backup Content
- **Data backups** contain QR codes, links, and URLs (may include sensitive information)
- **Config backups** contain environment variables and settings (may include passwords)
- **Full backups** contain entire application including source code
### Best Practices
1. **Encrypt backups** for off-site storage
2. **Secure backup storage** with appropriate access controls
3. **Regular backup testing** to ensure restoration works
4. **Monitor backup logs** for failures
5. **Rotate backup files** to manage storage space
### Encryption Example
```bash
# Encrypt backup for storage
gpg --symmetric --cipher-algo AES256 backup_file.tar.gz
# Decrypt when needed
gpg backup_file.tar.gz.gpg
```
## 📊 Monitoring
### Backup Status
Monitor backup health through:
1. **Web Interface**: Real-time status dashboard
2. **Log Files**: `backup.log` for automated backups
3. **API Endpoints**: `/api/backup/status` for integration
### Key Metrics
- Total number of backups
- Last backup timestamp
- Data directory size
- Total backup storage used
- Backup success/failure rates
## 🚨 Disaster Recovery
### Complete System Failure
1. **Prepare new environment**:
```bash
git clone <your-repo>
cd qr-code_manager
```
2. **Restore from full backup**:
```bash
./docker_backup.sh restore qr_full_backup_latest.tar.gz
```
3. **Verify configuration**:
- Check environment variables
- Update domain settings if needed
- Test database connections
4. **Start services**:
```bash
docker compose up -d
```
### Data Corruption
1. **Stop services**:
```bash
docker compose down
```
2. **Restore data only**:
```bash
./docker_backup.sh restore qr_data_backup_latest.tar.gz
```
3. **Restart services**:
```bash
docker compose up -d
```
## 🔧 Troubleshooting
### Common Issues
**Permission Errors:**
```bash
chmod +x backup.py docker_backup.sh
```
**Docker Not Found:**
```bash
# Check Docker installation
docker --version
docker compose version
```
**Backup Script Fails:**
```bash
# Check Python dependencies
python3 -c "import tarfile, json, pathlib"
# Check disk space
df -h
```
**Large Backup Files:**
Consider data cleanup before backup:
```bash
python3 clean_data.py
```
### Getting Help
1. Check the application logs: `docker compose logs`
2. Review backup logs: `tail -f backup.log`
3. Test backup creation manually
4. Verify file permissions and disk space
## 📈 Best Practices
### Backup Strategy
- **Daily**: Data backups (automated)
- **Weekly**: Config backups
- **Monthly**: Full backups
- **Before updates**: Create full backup
### Storage Management
- Keep last 15 daily backups
- Keep last 8 weekly backups
- Keep last 12 monthly backups
- Archive yearly backups off-site
### Testing
- Monthly restore tests
- Document restore procedures
- Train team on backup/restore process
- Test disaster recovery scenarios
---
**💡 Remember**: The best backup is one that has been tested! Regularly verify your backups can be restored successfully.

```bash
# Daily backup at 2 AM
0 2 * * * cd /opt/qr-code_manager && ./docker_backup.sh
# Weekly cleanup (remove backups older than 7 days)
0 3 * * 0 cd /opt/qr-code_manager && curl -X POST http://localhost:8066/api/backup/cleanup
```
### Docker Compose Automation
```yaml
# Optional: Backup service with automated scheduling
services:
backup-scheduler:
image: alpine:latest
command: >
sh -c "
apk add --no-cache curl &&
while true; do
sleep 86400;
curl -X POST http://qr-manager:5000/api/backup/create;
done
"
depends_on:
- qr-manager
```
## Security Considerations
### Access Control
- Backup operations require user authentication
- API endpoints validate user permissions
- Backup files are stored with restricted permissions
### Data Protection
- Backups contain sensitive application data
- Store backup files in secure locations
- Consider encryption for long-term storage
- Implement retention policies for compliance
### Network Security
- API endpoints use HTTPS in production
- Validate all input parameters
- Implement rate limiting for backup operations
## Troubleshooting
### Common Issues
#### "Backup creation failed"
- **Cause**: Insufficient disk space or permissions
- **Solution**: Check available space and file permissions
- **Command**: `df -h && ls -la backups/`
#### "Cannot delete backup file"
- **Cause**: File in use or permission denied
- **Solution**: Ensure file is not being accessed
- **Command**: `lsof | grep backup`
#### "Docker backup script not found"
- **Cause**: Script not executable or missing
- **Solution**: Check file exists and permissions
- **Command**: `chmod +x docker_backup.sh`
### Error Codes
| Code | Description | Action |
|------|-------------|---------|
| 200 | Success | Operation completed |
| 400 | Bad Request | Check request parameters |
| 404 | Not Found | Backup file doesn't exist |
| 500 | Server Error | Check logs and permissions |
### Debugging
Enable debug logging:
```bash
export FLASK_ENV=development
export FLASK_DEBUG=1
```
Check container logs:
```bash
docker compose logs qr-manager
```
## Performance Optimization
### Backup Size Optimization
- Implement incremental backups for large datasets
- Compress QR code images efficiently
- Exclude temporary files from backups
### Speed Improvements
- Use parallel compression for large backups
