Backing Up a Windows PC —
No Jargon

One copy is a coin flip

Hard drives don't warn you before they fail — they work fine on Tuesday and won't start on Wednesday, same as any aging machine. The difference is that a furnace doesn't take forty years of photographs with it. Backup just means keeping a second copy of the things you'd cry over losing, in a second place. That's the whole idea — everything else is details.

The good news: Windows already includes several free backup tools, and protecting against every common disaster — a dead drive, a deleted folder, theft, even ransomware — costs about the price of a tank of gas and one afternoon of setup. The catch is that nobody explains which tool does what. OneDrive alone is only half an answer, and the app named "Windows Backup" doesn't do what its name suggests. This guide untangles all of it, calmly, one step at a time.

What actually needs backing up (a shorter list than you think)

• Photos and videos — the Pictures folder, plus the strays parked on the Desktop and in Downloads.
• Documents — letters, recipes, tax files, anything you typed or scanned.
• NOT Windows itself, and not your programs — those can always be reinstalled. Spend your care on the things that can't be re-downloaded.
• Email, if it's Gmail or Outlook.com, already lives on the mail company's servers — signing in on any computer brings it back.

The simplest real backup — do this today

1. Buy one portable hard drive: 2 terabytes, Western Digital, Seagate, or Toshiba — about $60–$75 as of mid-2026. Skip the upsells.
2. Plug it into a USB port and open File Explorer (the yellow folder on your taskbar).
3. Click This PC — the drive shows up with a letter like (D:). Open it and make a new folder named today's date.
4. Open Documents, press Ctrl+A, then Ctrl+C. Open your backup folder and press Ctrl+V. Repeat for Pictures and Desktop.
5. When it finishes, open a few photos from the drive to prove they're really there. That's a genuine backup — as of today.

Turn on File History so it happens automatically

1. Hand-copying protects you as of the day you did it. File History is the same chore done for you, every hour, forever.
2. With the drive plugged in, click Start, type file history, and press Enter — it lives in the Control Panel, and it still works fine on Windows 11 as of mid-2026.
3. Click Turn on. The first backup starts by itself and covers Documents, Pictures, Music, Videos, and Desktop.
4. It even keeps old versions — ruin a document on Thursday and Tuesday's copy is still on the shelf. Click Restore personal files to reach back.
5. Leave the drive plugged in; that's how the hourly copies happen.

What OneDrive really protects — and what it quietly doesn't

• OneDrive copies the folders it's syncing to Microsoft's computers — so a fire, flood, or stolen laptop can't take your files. That part is genuinely great.
• But OneDrive is a mirror, not a vault: delete a file on your computer and it disappears from the cloud too, gone for good after about 30 days in its recycle bin.
• The free plan is 5 GB — a few hundred photos fills it. More room runs about $2/month for 100 GB, or about $10/month for 1 TB with Microsoft 365, as of mid-2026.
• A full OneDrive quietly stops protecting new files. Check the storage meter at onedrive.com now and then — by typing the address yourself, never from an email link.
• Confused about those little cloud icons and where files really live? My OneDrive Confusion guide is the companion to this one.

The app named "Windows Backup" — useful, but not what it sounds like

• Click Start and type windows backup — the app saves your settings, Wi-Fi networks, list of installed apps, and Start menu layout to your Microsoft account, and switches on OneDrive syncing for your folders.
• On a new or reset PC, sign in with the same Microsoft account and Windows offers to restore it all — settings return and your apps come back as pins to reinstall. Lovely on new-computer day.
• What it is not: a full copy of your computer, or the tool for getting back a file you deleted yesterday — that's File History or the OneDrive recycle bin.
• Turn it on anyway. It's free insurance for the day this computer gets replaced.

Drive plus cloud: why you want both

No single tool wins every disaster. The cloud copy survives the house fire; the File History drive survives the deleted folder you don't notice for two months and the ransomware that locks your files. Together they satisfy the professionals' 3-2-1 rule — three copies, two kinds of storage, one kept somewhere else — without you ever having to think about it. My 3-2-1 Backup Plan guide goes deeper if you want it. And test the whole thing twice a year: open File History, restore one file, open a few photos at onedrive.com. A backup you've never tested is a hope, not a plan.

Why I wrote this

The saddest house calls I make are the ones where the computer is fixable but the files aren't — a lifetime of photos on one worn-out drive, no second copy anywhere. And almost as common: folks who believed OneDrive had them covered, right up until a deleted folder vanished from both places. None of it takes expensive software or expertise to prevent — one $60 drive and the free tools already in Windows, set up once. So I wrote the guide I wish came in the box, in plain English, printable so you can keep it next to the computer. — Bill
