Use Cases

• Backup and migrate images from cloud providers to local storage
• Aggregate images from multiple services
• Automate scheduled backups (cron jobs, CI/CD)
• Archive management for organized local image storage
• Disaster recovery: maintain offline copies

Examples:

host-image-backup backup all --output ~/PhotoBackup
hib backup all --output ~/PhotoBackup

# Scheduled backup (cron)
0 2 * * * /usr/local/bin/host-image-backup backup all --output /backup/images --limit 100
0 2 * * * /usr/local/bin/hib backup all --output /backup/images --limit 100

# Migration between providers
host-image-backup backup start old-provider --output ./migration-temp
hib backup start old-provider --output ./migration-temp

---

Troubleshooting

Authentication errors:

• Check credentials and config file format
• Verify token expiration and permissions
• Test providers: host-image-backup provider test <provider>

Network issues:

• Check internet connection
• Increase timeout in config
• Use --verbose for details
• Check provider service status

File system errors:

• Ensure output directory exists and is writable

mkdir -p ~/backup && chmod 755 ~/backup
chmod 600 ~/.config/host-image-backup/config.yaml

Rate limiting:

• Lower max_concurrent_downloads
• Add delays between requests
• Use --limit to control download volume

Debugging:

host-image-backup provider test oss --verbose
hib provider test oss --verbose
host-image-backup provider info github
hib provider info github
host-image-backup backup start imgur --verbose --limit 5
hib backup start imgur --verbose --limit 5

Log analysis:

tail -f logs/host_image_backup_*.log
grep -i error logs/host_image_backup_*.log
grep -E "(Successfully|Failed)" logs/host_image_backup_*.log

---

Security

• Never commit credentials to version control
• Use environment variables for sensitive data
• Set restrictive permissions on config files:

chmod 600 ~/.config/host-image-backup/config.yaml

Environment variable example:

export OSS_ACCESS_KEY_ID="your_key"
export OSS_ACCESS_KEY_SECRET="your_secret"
export GITHUB_TOKEN="ghp_your_token"

Reference in config:

providers:
  oss:
    access_key_id: "${OSS_ACCESS_KEY_ID}"
    access_key_secret: "${OSS_ACCESS_KEY_SECRET}"

• Use HTTPS endpoints
• Consider VPN/private networks for sensitive data

Add new providers:

1. Create provider class in src/host_image_backup/providers/
2. Implement required methods from BaseProvider
3. Add config class in src/host_image_backup/config/config_models.py
4. Update provider registry in src/host_image_backup/providers/provider_manager.py
5. Add tests
6. Update documentation
