Device security basics
- Use a screen lock: PIN, password, fingerprint, or face recognition.
- Keep updates on: security updates matter more than new features.
- Turn on encryption: most modern devices enable this automatically.
- Install apps carefully: fewer apps reduce risk.
Why backups matter
Backups protect against loss, theft, device failure, and ransomware. Without backups, data loss is often permanent.
Common backup options
- Built-in backups: tools included with your operating system
- Cloud backups: services that automatically save data online
- External drives: offline backups stored separately
A simple backup plan
- Choose one automatic backup method.
- Confirm it runs regularly without reminders.
- Check occasionally that files are actually backed up.
- Keep at least one backup separate from your main device.
