How to Back Up Your Computer the Right Way (Step-by-Step)

March 30, 2026  ·  6 min read  ·  By Cincinnati PC Repair LLC

The hard truth about backups

We see it every week at Cincinnati PC Repair: someone comes in with a failed hard drive, a ransomware infection, or a stolen laptop — and everything is gone. Years of photos, important documents, financial records, everything. The conversation that follows is heartbreaking.

The overwhelming majority of people who lose data had no backup. And the overwhelming majority of those people had told themselves they'd set one up 'eventually.'

This guide will show you exactly how to back up your computer the right way — not eventually, but today. It takes less than 30 minutes to set up, and you'll only have to do it once.

The 3-2-1 backup rule

Professional IT departments follow what's called the 3-2-1 rule. It's simple and worth following:

  • 3 copies of your data
  • 2 different types of storage media
  • 1 copy stored offsite (away from your home)

In practical terms for a home user: your original files on your computer + a local external drive backup + a cloud backup. That's it. Let's set up each one.

Step 1: Cloud backup — your most important layer

Cloud backup is the most critical layer because it protects you from physical disasters (fire, flood, theft) and ransomware (which encrypts local backups too). If you only do one thing from this article, do this.

Our recommendation: Backblaze Personal Backup — $99/year for unlimited storage. It runs silently in the background and continuously backs up everything on your computer. If your hard drive dies tomorrow, you restore everything from the cloud.

Setup: Go to backblaze.com → download the app → install it → it starts backing up automatically. That's genuinely all there is to it.

💡 Pro tip: Google Photos (free) is great for photos specifically, but Backblaze backs up everything — documents, music, videos, software files — not just photos.

Step 2: Local external drive backup

A local backup lets you restore files quickly without downloading from the cloud, which can take hours or days for large amounts of data. You'll need an external hard drive — a 1TB drive costs around $50-60 and is more than enough for most people.

Setting up Windows Backup:

  • Plug in your external drive
  • Go to Settings → Update & Security → Backup
  • Click 'Add a drive' and select your external drive
  • Turn on 'Automatically back up my files'
  • Click 'More options' to set how often it backs up (hourly is fine)

Windows will now automatically copy your files to the external drive on your chosen schedule. Leave the drive plugged in and forget about it — Windows handles the rest.

⚠️ Warning: Don't store your external backup drive next to your computer. If someone breaks in and steals your laptop, they'll often take everything on the desk. Keep the backup drive in a drawer or different room.

Step 3: Verify your backups actually work

This is the step everyone skips and then regrets. A backup you've never tested is a backup you can't rely on. Every few months, do a test restore:

  • Pick a random file from your Backblaze or Windows Backup
  • Try to restore it to a different location
  • Confirm it opens correctly

If it works, great. If it doesn't, you've discovered a problem while you still have your original files — not after a disaster when it's too late.

What about OneDrive, Google Drive, or Dropbox?

These are sync services, not backup services. There's a critical difference: if you accidentally delete a file or ransomware encrypts your files, the sync service will faithfully sync those changes to the cloud — deleting or encrypting your cloud copy too.

OneDrive, Dropbox, and Google Drive are great for accessing files across devices. But they're not a substitute for a real backup solution like Backblaze. Use both — they serve different purposes.
