File History Backup in Windows 10: How to Set It Up

Updated 6 November 2026 · Standard formula, shown below

File History is the built-in backup tool in Windows 10 that automatically saves copies of your personal files (Documents, Pictures, Music, Videos, and Desktop) to an external drive or network location. You can set it up in a few minutes, and it lets you restore previous versions of files after accidental deletion, corruption, or ransomware attacks. This article explains every way to create and manage a File History backup, including setup steps, choosing a drive, changing backup frequency, and troubleshooting common issues.

What File History Does and How It Works

File History continuously monitors your libraries, desktop, contacts, and favorites folders. When enabled, it takes a snapshot of changes every hour (default) and saves them to a dedicated backup drive. It keeps multiple versions of each file, so you can go back to any point in time. The tool uses the NTFS change journal to detect modifications, so it only copies changed files, not entire libraries each time. It also recognizes when a file is renamed or moved and updates the backup accordingly, which many third-party tools fail to do.

File History is not a full system image backup. It does not back up installed programs, Windows settings, or the operating system itself. For a complete disaster recovery plan, you should also create a system image or use a third-party imaging tool. File History is designed for personal data only, and it works best when the backup drive is always connected, either via USB or network.

How to Turn On File History (First-Time Setup)

The quickest way to enable File History is through the Settings app, but the classic Control Panel method offers more options. Both are covered below.

Method 1: Using Windows Settings

Open Settings (Win + I) and go to Update & Security > Backup.
Under Back up using File History, click Add a drive.
Choose an external drive or network location from the list. Windows will automatically start backing up your files.
To change settings, click More options under the backup toggle.

Method 2: Using Control Panel

Open Control Panel (search for it in the Start menu).
Click File History (if you don’t see it, change the view to Large Icons).
Click Turn on in the left pane. If a drive is not connected, you’ll see a message; connect one and click Turn on again.

Both methods achieve the same result. The Control Panel gives you a clearer view of the backup drive and the option to exclude folders immediately.

Choosing a Backup Drive: External, USB, or Network

File History requires a drive that is separate from your system drive. You can use:

External USB drive – The most common choice. Plug it in, and Windows will list it as an available drive. If the drive is larger than your data, you can keep it plugged in permanently.
Network drive (NAS or shared folder) – Useful for multiple PCs or if you want backups off-site. In Control Panel, click Select drive and then Add network location. You’ll need the folder path (e.g., \\NAS\Backup) and credentials.
Second internal drive – If you have a desktop with an extra hard drive, you can use it, but it must be a separate physical disk, not a partition of the same drive.

Windows will not let you use the same drive that contains your user folders. It also warns if the drive is too small. A good rule of thumb is to have at least 1.5 times the size of your data, but more is better if you want to keep months of versions.

Configuring File History Settings (Frequency, Retention, and Folders)

After enabling File History, you can fine-tune how it works. In Settings > Update & Security > Backup > More options, you can:

Back up my files – Choose how often snapshots are taken. Options range from every 10 minutes to daily. The default is every hour.
Keep my backups – Set how long versions are kept: until space is needed, 1 month, 3 months, 6 months, 1 year, 2 years, or forever. The default is “Forever,� which can fill a drive quickly.
Back up these folders – Add or remove folders. By default, it includes all libraries (Documents, Pictures, Music, Videos) plus Desktop and Contacts. You can add any folder on your PC, but note that File History only backs up folders in your user profile by default; adding a folder outside that requires it to be in a library or you must add it manually.
Exclude these folders – Prevent certain folders from being backed up. For example, you might exclude a Downloads folder to save space.

In the Control Panel, you can also click Advanced settings to change the same options, plus set the offline cache size (for laptops that are sometimes disconnected from the network).

How to Restore Files from File History

Restoring is just as important as backing up. There are two main ways:

Restore from the File History window

Open File History in Control Panel.
Click Restore personal files on the left.
Browse through the folders and versions using the arrows at the bottom. You’ll see a timeline of snapshots.
Select the file(s) or folders you want, then click the green Restore button.
If you want to restore to a different location, right-click the restore button and choose Restore to.

Restore from File Explorer

Navigate to the folder that originally contained the file.
Right-click the folder (or the file if it still exists) and select Properties.
Go to the Previous Versions tab. You’ll see a list of available versions from File History.
Select a version and click Restore (overwrites current) or Open to view it first.

This method is handy when you know exactly which file you need and want to compare versions.

Common Problems and How to Fix Them

File History is generally reliable, but a few issues are common:

“File History is turned off� after reboot – This often happens if the backup drive is disconnected or the service didn’t start. Check that the drive is connected and go to Control Panel > File History > Turn on. Also, ensure the File History Service is set to Automatic in Services.msc.
Backup drive is full – File History will stop backing up. Clean up old versions by going to Advanced settings > Clean up versions, or change the retention policy to “Until space is needed.�
Network drive not showing – Make sure the network location is accessible and you have write permissions. In Control Panel, click Select drive > Add network location and enter the UNC path (e.g., \\Server\Share).
Files are not being backed up – Check if the folders are included in the backup list. Also, File History does not back up files that are open in exclusive use by another program; close the file and run a manual backup (click Run now in Control Panel).
Error 0x80070005 (Access Denied) – This can occur if the backup drive is formatted with FAT32 or exFAT. Reformat the drive to NTFS (backup data first) to fix it.

File History vs. Other Backup Options in Windows 10

Windows 10 offers several backup tools, and it’s important to know the difference:

File History – Best for personal files. Automatic, versioned, easy to restore. Not a full system backup.
Backup and Restore (Windows 7) – This legacy tool creates system images and file backups. It can be used alongside File History, but it’s not as flexible for versioning.
System Image Backup – A full snapshot of the entire OS drive. Useful for disaster recovery, but it’s a single point-in-time copy, not continuous.
OneDrive – Cloud storage that syncs your files. It’s not a true backup because deletions sync too, but it offers version history and ransomware protection. You can use both OneDrive and File History for redundancy.

For most users, File History plus a system image (created occasionally) is a solid combination. For business-critical data, consider a third-party backup solution with off-site storage.

Frequently Asked Questions

Does File History back up the entire system?

No. File History only backs up files in your user libraries, desktop, contacts, and any folders you explicitly add. It does not back up installed programs, Windows settings, or system files. For a full system backup, use the System Image tool or a third-party imaging program.

Can I use a network drive for File History?

Yes. In Control Panel, click Select drive > Add network location, then enter the path to a shared folder. The network drive must be accessible when you turn on File History, and you’ll need write permissions. Note that the backup may be slower over Wi-Fi.

How much space does File History need?

It depends on the size of your data and how long you keep versions. A good starting point is 1.5 to 2 times the size of your backed-up folders. If you keep backups “Forever,� the drive will eventually fill up. You can monitor usage in the File History window.

Can I back up to the same drive as my Windows installation?

No. Windows prevents you from using the system drive (the one with Windows installed) as the File History destination. You must use a separate physical drive, whether internal or external. This is to protect against drive failure.

What happens if I delete a file after File History was running?

You can still restore it. Open File History and click Restore personal files. Navigate to the folder where the file used to be, select the version from before deletion, and restore it. The file will reappear in its original location.

Does File History work with OneDrive files?

Yes, but with a caveat. If you use OneDrive with “Files On-Demand,� the actual file content may not be on your PC. File History will back up the placeholder, not the full content. To back up the full file, you need to make it “Always keep on this device� or use OneDrive’s own version history.
