- "Hello! I'm having problems with File History backups; I experienced the same problem with my Surface Pro 3 as well. A year later, it appears that the problem has not been resolved. I only discovered today that not all of my files are being backed up, despite the fact that I've put them in the "Back up these folders" list.
Is there a method to resolve this? Backups are really important to me, and doing them manually is honestly not the best option for me; it's time-consuming and cumbersome. I'm used to using Time Machine on Mac OSX, and backups have been my main concern since switching to Windows." - from Microsoft Community
Have you ever had the same problem with the Windows 10 backup not backing up all source files or not working at all? Actually, Backup and Restore and File History are two built-in backup programs for Windows computers. According to customer comments, both solutions have the issue of Windows backup not backing up all files.
Don't be concerned if you find yourself in the same circumstance. This article will walk you through the exact reasons why the backup files are missing, as well as how to remedy it step by step. Furthermore, to avoid making the same mistake or if you don't want to try the remedies one by one, we will provide a superior alternative, EaseUS Todo Backup, to make the backup procedure much easier.
File History was first introduced in Windows 8 build, and is also available on Windows 8.1, Windows 10, and Windows 11. It has the feature to automatically backup your files, including Document files, photos, videos, music, and desktop files, to the external hard drive or network locations.
When you have trouble with File History not backing up all files, it may be caused by the following factors:
- The source file is corrupted or destroyed;
- The files name contain special symbols;
- The files are under a deep directory structure;
- Your files are encrypted and protected;
- File History application error;
- The backup target locations are running out of storage.
We have given several solutions based on the causes, and we hope they will properly resolve the issue.
Fix 1. Delete Previous Backups and Enable File History Again
If the backup missing files issue is caused by a File History application error, you can turn it off, and then enable it to try the file backup task again. By doing so, the File History will be force refreshed. If it doesn't work, you may need to delete the previous backups and try another time.
Fix 2. Check and Modify File Names or Directory Structure
These file names containing unusual symbols are not recognized by File History. Check to see if the ignored file name contains any special characters. If so, modify and eliminate them.
Another explanation could be that you saved the file in a deep directory structure, resulting in a failed backup. In this situation, remove it from the original path and reorder it.
Fix 3. Run SFC to Repair the Corrupted Files
SFC (System File Checker) is a useful program for automatically locating corrupted or damaged files and replacing them with intact ones. If the backup ignores some files, it is possible that these files are corrupted.
Step 1. Enter Command Prompt in the search bar, and open it Run as administrator.
Step 2. Type the command scf /scannow, and click Enter.
Step 3. It will detect the destroyed files, and repair them automatically.
Fix 4. Decrypted Encrypted Files
File History can't back up files that are EFS encrypted. If you receive an error notice such as "File history has found files that are encrypted with Encrypting File System" or something similar, please check to see if your files or folders have been encrypted. If so, you may need to decrypt them before backing them up.
Fix 5. Check Backup Target Location Storage Space
Most users will disregard the target location storage space and will rarely check it. Your file cannot be successfully backed up if it is too large. In this case, you should prepare a new hard drive or delete unnecessary files. You can check and deal with your hard drives with Windows Disk Management.
Backup and Restore (Windows 7) is another commonly used Windows built-in backup program. Available on Windows 7/10/11, it allows users to create a system image and backup specific files and folders. However, it doesn't work as smoothly as imagined every time. It is said that many users have gotten notices, saying "The backup did not complete successfully", or "The last backup did not complete successfully" on Windows 10.
The Windows backup didn't complete successfully may be caused by many reasons. Here are some possible ones:
- File corruption or damage;
- Insufficient hard drive space;
- Unstable connection;
- Malware or virus attack.
Now, follow the methods below to fix the issue.
Fix 1. Perform SFC to Check the Files
Running System File Checker (SFC) can assist in identifying and repairing these files. SFC may be executed by opening Command Prompt as an administrator and typing "sfc /scannow" and clicking Enter. It is possible that the process will take some time, and the computer will need to be rebooted afterwards.
Fix 2. Check Hard Drive space
You should check their hard drive space and ensure there is enough to complete the backup. If the hard drive is full, users can free up space by deleting unnecessary files or transferring them to an external drive.
Fix 3. Check the Connection
Check the connecting cable and ensure it is correctly attached when backing up to an external hard disk. Users can also try a different cable or USB port to see if it helps.
Fix 4. Scan and Delete malware and Virus
Malware and viruses can disrupt the backup process. Run a comprehensive system scan and remove any malware or viruses found.
Windows 10 includes built-in antivirus protection in the form of Windows Security, which can be reached by typing "Windows Security" into the search bar and then opening the app. Users can then choose "Virus & threat protection" and "Scan options" to perform a comprehensive scan.
