The Office Backup That Actually Works

The Mantua shop that lost everything

A small repair shop in Mantua called me one Saturday morning last March. Their main office PC — a five-year-old Dell humming under the counter — was running QuickBooks Desktop, the Outlook PST with eight years of customer email, the scanned contracts folder, the photo library of every job they'd done going back to 2017, and the spreadsheet that tracked who owed what. One drive. No backup. Friday afternoon the SSD started clicking. Saturday morning it wouldn't boot.

Eight years of customer records were partially reconstructed from QuickBooks reports printed in 2019. The Outlook PST was gone entirely. The job photo library — about 4,000 pictures of finished work — completely lost. The owner estimates the total cost in lost time, rebuilt records, and irretrievable photos at over $12,000, not counting six weeks of operational chaos. The fix would have been about $20 a month and one Saturday of setup, three years earlier.

What a small business has to back up

Walk through your office in your head. Make the list — most shops are surprised how long it is. QuickBooks files. Outlook PST or M365/Workspace cloud mail. Customer records (CRM or a folder structure). Job photos. Signed contracts. Marketing assets. Browser bookmarks and saved Outlook rules. Software license keys. Custom spreadsheets and Excel templates the bookkeeper made. If your one office PC died tonight, every one of those needs a plan.

3-2-1, the shop version

• Cloud business backup — Backblaze Business, iDrive Business, or Carbonite. Off-site, versioned, ransomware-resistant.
• Local NAS or external drive — Synology NAS or USB drive plugged into the office PC. Fast restore, no internet needed.
• Cold spare drive — lives in the office safe, the owner's truck, or a relative's house. Refreshed monthly. Unplugged otherwise. This is the ransomware insurance policy.

What's in the 27-page PDF

• Backblaze Business Backup — pricing (~$99/year per computer, verify current), what it backs up, what it doesn't, setup in 30 minutes per PC.
• iDrive Business — honest comparison, when it's the right call (servers, multi-device pooled storage, image-level restore).
• Carbonite — why I don't recommend it for new installs in 2026, but what to do if you already have it.
• Bill's pick for a 1-10 person shop (Backblaze + Synology NAS + cold spare), with costs.
• The Synology NAS — why it's the single piece of hardware that levels up a small-shop setup, sizing (DS224+ vs DS923+ vs DS1522+), drive choice (NAS-rated only).
• Time Machine on the office Mac, File History and Macrium for the Windows PC, Synology Active Backup for Business across the whole office.
• The cold-spare external drive — where it lives, what's on it, the monthly refresh schedule.
• QuickBooks specifically — Desktop file backup vs QuickBooks Online backup vs Intuit Data Protect.
• Email archive — why your provider isn't your only copy, the Outlook PST archive, MailStore for serious shops.
• Job photos, contracts, and customer files — the data that's not in QuickBooks but matters as much.
• Ransomware and air-gapped backups — what ransomware can and can't encrypt, and why the cold spare wins.
• The quarterly restore test — actually do it. Four tests in 30 minutes.
• The first hour of a disaster — the call-your-cyber-insurance-carrier-first script.
• Documenting the runbook so somebody else can recover the business if you're unavailable.
• The eight common mistakes Bill sees weekly.
• The morning, weekly, monthly, and quarterly checklists.
• The 90-day backup rollout plan — going from zero to a real plan, in the right order.

Why this is a separate guide from the 3-2-1 household one

I wrote a household backup guide already — different files, different stakes, different tools. A household runs on iCloud and an external SSD. A shop has QuickBooks Desktop, an Outlook PST with customer history, signed contracts, an employee who might leave with a laptop, and the very real ransomware threat that's climbing every year. The cloud-backup product is different (Backblaze Business, not Personal), the local layer is different (a NAS, usually, not just a USB drive), and the daily discipline is different (a morning checklist by the coffee pot, not an annual review). Same rule. Different tools. — Bill
