It seems that the latest update of Windows 10 is causing problems with the system backup tool called "File History" for some users. In addition to backup issues, several users have also found that the update interrupts webcam operation, interrupts applications, and does not install them in some cases.
For those who do not know, File History is the default backup solution for Windows 10 and allows you to take snapshots of your files and save them on a USB stick or elsewhere on your home network.
File History is a "set-it-and-forget-it backup solution", but as it appears after the update KB4601319 (February 2021 update) does not work.
One user reports that "Backup Options" appears on the screen after a noticeable delay and the process simply fails with the "Your data has not yet backed up" error. When users click "Backup Now", the "Cancel" button appears and the backup function does not work.
Another attempt to run the backup tool fails with the following message:
"We can not copy files to the File History drive. Failed to start backing up user data (Error 80070005) ”.
"I'm been facing exactly the same problem since February 10, 2021. I tried a complete File History reset: deleted configuration files, deleting the backup folder. I changed the destination to another external drive and the problem persists. Removing the KB4601319 update fixed the problem, "says another user.
The good news is that uninstalling update KB4601319 fixes the problem for all affected users.
Microsoft has not yet recognized the error with the File History tool, but confirmed that investigates webcam issues that affect the functionality of Windows Camera and Windows Hello.
