Protect your important files by setting up automatic backups on your Windows computer using built-in backup tools.

Step 1. Set up OneDrive cloud backup
Open Settings, click "Accounts," then "Windows backup." Toggle on Desktop, Documents, and Pictures to back up these folders to OneDrive automatically. You get 5 GB free with your Microsoft account.
Step 2. Connect an external drive
Plug a USB external hard drive into your computer. This drive will store local backup copies of your files using File History.
Step 3. Enable File History
Go to Settings then System then Storage then Advanced storage settings then Backup options. Click "Add a drive" and select your external hard drive. File History will begin backing up your files.
Step 4. Customize backup frequency
Click "More options" under File History settings. Set how often backups run (every hour is recommended) and how long old versions are kept (at least 3 months). You can also choose which folders to include.
Step 5. Test restoring a file
Open File Explorer, navigate to any folder, click the "Home" tab, and click "History." Browse through saved versions of your files to confirm the backup is working. Select a file and click the green restore button to bring it back.
Step 6. Check backups monthly
Once a month, open your backup settings and verify that backups are running. If using an external drive, make sure it is still connected and has available storage space.
Backing up your computer means creating copies of your important files so you can recover them if something goes wrong — whether your hard drive fails, your computer gets a virus, or you accidentally delete something important. Windows has built-in backup tools that make this process straightforward once you set them up.
Windows 11 offers two main backup approaches: OneDrive cloud backup and File History (for backing up to an external drive). Using both together gives you the strongest protection.
For cloud backup with OneDrive, open Settings, click "Accounts," then "Windows backup." Here you will see options to back up your folders (Desktop, Documents, and Pictures) to OneDrive. Toggle on the folders you want to back up. Files in these folders will automatically sync to the cloud, meaning they are saved online in your Microsoft account. You get 5 GB of free OneDrive storage. If you need more, Microsoft 365 subscriptions include 1 TB of OneDrive storage.
For local backup with File History, you need an external hard drive or USB drive. Plug in your external drive, then open Settings and go to "System" then "Storage" then "Advanced storage settings" then "Backup options." Under "Back up using File History," click "Add a drive" and select your external drive. Once set up, File History automatically saves copies of your files at regular intervals.
You can customize how often File History runs and how long it keeps old copies. Click "More options" under File History to adjust these settings. Backing up every hour and keeping saved versions for at least 3 months is a good balance between protection and storage use.
To restore files from a File History backup, open File Explorer, navigate to the folder where the file was, click the "Home" tab, and click "History." You can browse through previous versions of your files and restore the one you need.
The most important rule of backups: they only protect you if they are running. Check your backup settings once a month to make sure everything is still working. If you use an external drive for File History, keep it plugged in or plug it in regularly so backups can run.
