I have been using FBackup for some time to create a daily mirror backup of my user data files without issues.
I recently started getting 4 warnings in my backup log for the Guest account's library files. They are all about the same and read as follows --
Warning: Skipping file C:\Users\Guest\AppData\Roaming\Microsoft\Windows\libraries\Videos.library-ms
Source error (code 5). Access is denied. (C:\Users\Guest\AppData\Roaming\Microsoft\Windows\libraries\Videos.library-ms).
The same happens for the documents, music and pictures libraries. And it happens even though no one is logged in as Guest to cause a denial of access.
Two questions --
1. What changed to cause these new warnings.
2. Why do they continue after deleting and restoring the default libraries for the Guest account?
If there is an solution without excluding similar AppData\Roaming\Microsoft\Windows\libraries files, please let me know.
