File History Not Backing Up? Fix a Stuck Windows Backup

You plug in your backup drive, expect Windows to quietly protect your files, and then discover File History has not backed up anything for days or weeks. If File History not backing up is the problem you are dealing with, the good news is that it is often caused by a simple disconnect, service issue, or settings glitch rather than lost data.

In this guide, you will learn how to check the most common causes, reconnect the backup drive, and get File History running again without rebuilding your whole backup plan.

Why this happens

File History relies on a few things working together: the backup drive must be available, the File History service must be running, and the folders you want protected must still be included in your Windows libraries or supported locations. If any part of that chain breaks, Windows may stop backing up without making it obvious.

This can happen after a Windows update, a drive letter change, a loose USB connection, an external drive going to sleep, or corruption in the existing File History configuration. Network backup locations can also trigger this issue if the PC cannot see the shared folder when the backup tries to run.

Fix it step by step

1. Confirm the backup drive is connected and visible.
   Open File Explorer and check whether your external drive or network location appears normally. If you use a USB drive, unplug it and reconnect it directly to the computer instead of through a hub if possible. If the drive does not appear, restart the PC and try a different USB port.
2. Make sure the drive letter has not changed.
   File History may fail if Windows assigned a different drive letter than the one it was using before. Press Windows + X, select Disk Management, and confirm the backup drive still has the same letter. If the drive is present but changed, note the new letter and continue to the next steps to reselect it inside File History.
3. Check File History status in Settings or Control Panel.
   In Windows 10, go to Settings > Update & Security > Backup. In Windows 11, search for File History from the Start menu and open it through Control Panel. See whether it says the drive is disconnected, the backup is off, or the last backup date is old. If you see an option to Run now, try it and watch for any error message.
4. Turn File History off, then select the drive again.
   If File History shows the wrong drive or says your drive is unavailable, choose Stop using drive or Turn off, then set it up again with the correct drive. This usually keeps your existing backup data on the external disk, but Windows creates a fresh link to it. Once the drive is selected, click Turn on or Run now.
5. Restart the File History-related services.
   Press Windows + R, type services.msc, and press Enter. Look for File History Service if it appears on your system, and also check services such as Windows Search and Volume Shadow Copy. If any are stopped, right-click and choose Start. If they are running, choose Restart. Then test File History again.
6. Free up space on the backup drive and your system drive.
   File History can stall if the destination drive is nearly full or if Windows does not have enough working room on the main drive. Delete unneeded files from the backup disk only if you are certain they are not part of backups you still need. You can also change the retention setting in File History so old versions are not kept forever.
7. Exclude a problem folder or file type.
   If File History hangs every time it runs, one damaged or very large folder may be causing the issue. Go into File History settings and temporarily exclude folders with huge media archives, active Outlook data files, or unusual synced folders. Run the backup again. If it works, add folders back one at a time to find the trigger.
8. Reset the File History configuration if nothing else works.
   Turn File History off first. Then open File Explorer and browse to %localappdata%\Microsoft\Windows\FileHistory. Rename the Configuration folder to something like Configuration-old instead of deleting it. Turn File History back on and choose your backup drive again. This forces Windows to build a fresh configuration while preserving the old one as a fallback.

If the problem keeps coming back

If File History keeps failing after you reconnect the drive and reset the settings, the issue may be with the external drive itself, unstable USB power, file system errors, or a backup target that disconnects during sleep or startup. At that point, it is smart to test the drive on another PC, run Windows error checking, and consider a second backup method so you are not relying on one copy alone.

Frequently asked questions

Will I lose old backups if I reselect the File History drive?

Usually, no. In many cases, Windows can continue using the existing backup data on that drive after you point File History to it again. Even so, avoid manually deleting backup folders unless you are sure they are no longer needed.

Why does File History say my drive is disconnected when it is plugged in?

This often happens when the drive letter changed, the USB connection is unstable, the drive is slow to wake up, or Windows is looking for a network location that is no longer available. Reselecting the drive and restarting the related services usually helps.

Is File History enough for full backup protection?

File History is useful for keeping versions of personal files, but it is not a complete system image solution. For stronger protection, many people combine File History with cloud storage and a full-disk backup tool so they can recover both documents and the operating system.
