The 3-2-1 Backup Rule, Actually Explained (With Tampa Examples)

3 copies, 2 media, 1 off-site — what each part really means and the two setups that cover small offices and teams.

  1. 1. Count your real copies (most people have one)

    List where your photos and documents exist: PC counts as one. A plugged-in external drive attacked by the same ransomware or surge counts as zero additional protection. Cloud sync counts only if versioning is on.

  2. 2. Build the small-business setup: PC + cloud + annual archive

    Automated cloud backup (Backblaze/iCloud/OneDrive class) plus a yearly external drive stored elsewhere (safe deposit, a colleague off-site). That rotation survives office fire, flood, and theft — Tampa's actual threat list.

  3. 3. Build the office setup: local speed + cloud safety

    NAS or server backup for fast restores plus encrypted cloud replication for disasters. Test one file restore monthly — the businesses that test are the ones that survive.

The 3-2-1 Backup Rule, Actually Explained (With Tampa Examples) — When to Call a Pro

  • You're starting from zero copies of anything important — triage and build urgently.
  • Business retention or compliance rules dictate what 'backup' must legally mean.
  • Last storm proved the plan fictional — rebuild it before the next cone of uncertainty.

Guide FAQ

No — RAID survives drive failure only. Accidental deletion, ransomware, fire, and theft all laugh at RAID. It's uptime, not backup.
