Implement 3-2-1 Backup Strategy
Why
A comprehensive backup system is crucial for protecting your data against loss due to hardware failure, theft, ransomware, or disasters. The 3-2-1 backup strategy ensures you have multiple copies of your data in different locations, significantly reducing the risk of total data loss.
Action
Understand the 3-2-1 backup rule:
- 3 copies of your data (1 primary + 2 backups)
- 2 different storage media types
- 1 copy stored off-site
Choose your backup solutions:
- Primary backup (local):
- External hard drive or Network Attached Storage (NAS)
- Secondary backup (local, different type):
- Another external drive or a set of high-capacity USB drives
- Off-site backup (cloud):
- Dedicated backup services: Backblaze, iDrive, Carbonite
- Or use existing cloud storage: iCloud, OneDrive, Google Drive, Dropbox
- Primary backup (local):
Set up automatic local backups:
- Windows: Enable File History (Settings > Update & Security > Backup)
- macOS: Enable Time Machine (System Preferences > Time Machine)
- Connect an external drive and leave it plugged in for automatic daily backups
- Alternative: Use a Network Attached Storage (NAS) for wireless backups
Set up cloud backup:
- Choose between dedicated backup service or cloud storage
- Install the application and sign in
- Select folders to backup (Documents, Desktop, Photos, etc.)
- Enable automatic sync/backup
- Verify encryption is enabled
Test your backups:
- Monthly: Restore a few random files to verify they work
- Annually: Perform a full restore test to a spare device
Secure your backups:
- Encrypt local backup drives using BitLocker (Windows) or FileVault (Mac)
- Use strong, unique passwords for cloud services
- Enable two-factor authentication on all cloud accounts
Create a backup schedule:
- Continuous/Daily: Automatic cloud backups
- Daily: Local backups (if drive stays connected)
- Weekly: Full local backup if you disconnect drives
- Annually: Archive important data to a separate drive stored off-site
Document your backup system:
- List what’s backed up and where
- Store recovery instructions in your password manager
- Include encryption passwords and recovery keys
Remember
Regularly review and update your backup strategy. As your data changes, ensure your backup system still covers all crucial information.
