Backups & Device Updates
Updates fix security holes. Backups protect you if something goes wrong (lost device, ransomware, accidental deletion).
Why updates matter
Simple truth
Most successful hacks use old known vulnerabilities that updates already fixed.
Update habits
- Turn on automatic updates where possible
- Update browsers, apps, and operating system
- Restart your device when updates require it
Backups (your recovery plan)
Good backup approach
- Use cloud backup (Google Drive, OneDrive, iCloud) for key files
- Keep an external drive backup for important data
- Test restore occasionally (make sure it actually works)
Ransomware protection
If you have a backup, ransomware loses power over you. You can wipe and restore instead of paying.
Key takeaways
- Updates close security holes
- Backups protect you from loss and ransomware
- Automatic updates + cloud backup = strong baseline security
