I have already setup my C:\Users folder as Back up option on my Surface Pro running Windows 10 Fall Creators Update. The “Automatically back up my files” has been enabled in Settings app. However, when I try to restore the necessary files, some hidden folders like AppData are missing by File History. I do that manually and still could not archive the whole user account with all files to an external drive. How can I resolve the problem?
You might have set the user library as the location to backup, while reassigned the location of such library. The File History will not backup those folders and bypass them. I enable the hidden feature in File Explorer and notice that some reparse points are inside. Here are the method to get rid of that.
* From your desktop, type File History in Search box or Start menu, and select the top one from results.
* Click on the Advanced Settings, and scroll down to the bottom to view the Events logs of File History. On my Surface Pro, it displays the “Directory C:\Users\username\SendTo was not backed up because it is a reparse point”. I remove it and the issue is fixed.
* If you want to find out all reparse point, open the command prompt (Admin), use CD command to navigate to that parent folder, and execute the
dir /a to get the list.
The entries with “junction” cause the problem. The work around is to remove this reparse point from the library, and the backup wizard will work normally with everything.
Another method is to right-click on the library with a Reparse point, and select properties to get the actual location. Then moved files to a new physical disk and partition, and add them to File History. If the backup process fails with 0×81000037 error, open its folder’s Properties, and run the “Disk Cleanup”.
