Backups aren’t “nice to have”. They’re what turns a disaster (ransomware, theft, hardware failure, accidental deletion) into a manageable inconvenience. This guide covers the simplest, most reliable approach we recommend to clients across New Zealand.

What should you back up?

  • Business: shared files, accounting data, customer records, email/mailboxes, Microsoft 365/Google Workspace data, line-of-business apps.
  • Home: photos/videos, device backups, important documents, password manager vaults, email.

The 3-2-1 rule (the simplest reliable strategy)

Use the 3-2-1 approach:

  • 3 copies of your data (the original + 2 backups)
  • 2 different storage types (e.g., external drive + cloud)
  • 1 off-site (cloud or stored away from the device/location)

Cloud backup vs sync (important difference)

Services like OneDrive/Google Drive are great, but they’re primarily sync. If a ransomware attack encrypts files or someone deletes a folder, sync can replicate the damage. A true backup includes version history, retention, and ideally an immutable or isolated copy.

A practical setup (home + small business)

  1. Local backup to an external SSD/HDD (automated daily).
  2. Cloud backup with versioning and retention (automated).
  3. Quarterly restore test to confirm it actually works.

Ransomware protection tips

  • Enable MFA on email and cloud accounts.
  • Use a password manager and unique passwords.
  • Separate admin accounts from daily-use accounts.
  • Keep one backup copy “offline” (not always connected).
