Losing photos, documents, or tax files is one of the most stressful things that can happen to a computer, and it almost always happens at the worst time. The good news is that Windows 11 comes with two free, built-in ways to protect your files, and once you switch them on, they keep working quietly in the background without you having to remember a thing.
In this guide we'll walk you through both methods in plain English: backing up your important folders to OneDrive (Microsoft's cloud), and copying your files to an external drive with a tool called File History. We'll also explain the simple "3-2-1" rule the pros use, and how to get your files back if something ever goes wrong. You don't need to be tech-savvy, and you can always call Browning PC if you'd rather we set it up for you.
Understand the simple 3-2-1 rule
Before you start, here's the idea the pros follow, made simple: keep 3 copies of anything you'd hate to lose, on 2 different kinds of storage, with 1 copy somewhere off-site. In real terms that means your original files on your PC, a copy on an external drive (File History), and a copy in the cloud (OneDrive). The two methods in this guide cover the whole rule together, which is why we recommend doing both.
💡 If you only have time for one thing today, turn on OneDrive first. It needs no extra hardware and protects you even if the whole computer is lost or stolen.
Turn on OneDrive folder backup in Settings
OneDrive automatically copies your most-used folders to the cloud. Open the Start menu, go to Settings, then Accounts, then Windows backup. Next to 'OneDrive folder syncing', select 'Set up syncing' (or 'Manage sync settings' if it's already running). Expand the Folders list and turn the switch On for the folders you want protected, such as Desktop, Documents, Pictures, Videos, and Music, then select Save changes. Your files start copying to the cloud right away.

💡 A free Microsoft account includes 5 GB of cloud storage. If you have lots of photos and videos, you may want a Microsoft 365 plan, which includes much more space.
Check the OneDrive icon to confirm it's syncing
Look in the bottom-right corner of the screen near the clock for the blue OneDrive cloud icon. If you don't see it, click the small upward arrow to show hidden icons. A blue cloud means OneDrive is on; check marks on your files in File Explorer mean they're safely backed up. You can click the cloud, then the gear icon, then Settings, and open the 'Sync and backup' tab to manage which folders are covered.

💡 A green circle with a white check means the file is also saved on your PC; a small cloud means it lives online to save space and downloads when you open it.
Plug in an external drive for File History
OneDrive covers the cloud; File History covers a physical copy you hold in your hand. Plug an external USB hard drive (or a large USB flash drive) into your PC. If Windows asks what you'd like to do with the drive, you can close that pop-up. Make sure the drive has enough space, ideally as large as or larger than the amount of data on your PC.
💡 A dedicated drive used only for backups is best. Don't use it as your everyday drive for moving files around.
Turn on File History
In the Start menu search box, type 'Control Panel' and open it. Choose 'System and Security', then 'File History'. If your external drive isn't already chosen, click 'Select drive' on the left, pick your drive, and click OK. Then click 'Turn on'. File History will make its first copy and then keep updating it automatically.

💡 File History automatically backs up your Documents, Pictures, Videos, Music and Desktop folders. You can leave the drive plugged in so it backs up on its own throughout the day.
Know what each method covers
It helps to know the difference so nothing falls through the cracks. OneDrive protects the folders you turned on (Desktop, Documents, Pictures, Videos, Music) and keeps them safe even if your computer is lost, stolen, or destroyed. File History keeps multiple older versions of your personal files on the external drive, so you can go back in time, but only protects what's on that drive. Neither one backs up installed programs or Windows itself, just your personal files.
💡 Because they cover slightly different things and live in different places, using both gives you the strongest protection with the least effort.
Restore a file you lost or changed by mistake
To get a file back from File History, plug in your backup drive, open File Explorer, and go to the folder the file used to be in. Right-click that folder (or an empty space inside it), choose 'Show more options', then 'Restore previous versions'. Pick the version you want and click the green Restore button. To restore from OneDrive, sign in at onedrive.com or open the OneDrive folder, where you can also recover deleted files from the Recycle Bin for up to 30 days.
File ExplorerRight-click the folderShow more optionsRestore previous versions
💡 Use the arrow next to 'Restore' and choose 'Restore to...' if you want to save the recovered copy somewhere new rather than overwriting the current file.
Make backups a habit you don't have to think about
The best backup is the one that runs by itself. Leave OneDrive turned on so your folders stay synced automatically, and keep your File History drive plugged in (or plug it in once a week) so it keeps a fresh copy. Every few months, open one of your backups and confirm you can actually see and open your files, that quick check is the difference between a backup that works and one you only hoped was working.
💡 Set a recurring phone reminder, like the first of the month, to plug in your drive and glance at your backups. Two minutes now saves a heartbreak later.

Frequently Asked Questions
What's the difference between OneDrive and File History?
OneDrive copies your chosen folders to Microsoft's cloud, so they're safe even if your computer is lost, stolen, or damaged, and you can reach them from any device. File History copies your files to an external drive you keep at home and saves older versions so you can go back in time. They cover slightly different risks, so using both is ideal. Neither backs up your installed programs or Windows itself, only your personal files.
Is backing up my Windows files free?
Yes. Both OneDrive folder backup and File History are built into Windows 11 at no cost. The only optional expenses are an external drive for File History (about $40–$80) and extra OneDrive storage if your 5 GB of free cloud space fills up. For many people the free tools are enough to get protected today.
How much can OneDrive back up for free?
A free Microsoft account includes 5 GB of OneDrive cloud storage, shared across your OneDrive files, Outlook.com attachments, and Microsoft 365 apps. That's plenty for documents but can fill up fast with photos and videos. If you need more room, Microsoft 365 Personal includes 1 TB (1,000 GB) and adds Office apps, Microsoft 365 Basic adds 100 GB, or you can buy additional OneDrive storage on its own.
Do I need to leave my external drive plugged in all the time?
It's the easiest way. If your File History drive stays connected, Windows backs up your files automatically in the background throughout the day. If you'd rather unplug it, just plug it back in at least once a week so it can refresh your backup, and Windows will catch up on anything that changed while it was unplugged.
Can I get back a file I deleted or changed by accident?
Yes. With File History, open the folder the file was in, right-click, choose 'Show more options' then 'Restore previous versions', and pick an earlier copy. With OneDrive, deleted files sit in the online Recycle Bin for up to 30 days, and you can also view earlier versions of a file from the OneDrive website. This is exactly what backups are for, so don't panic if you delete something by mistake.
