Situation: I have updated Windows 10 from 1709 to 1803

With Windows 10 1709:  Acronis 2018 works perfectly.

With Windows 10 1803 there were problems: Acronis 2018 / W10 1803 will not make backup of OneDrive local folders and files. I get error messages and may stop backing up OneDrive.

 All other drives, folders and files were backed up OK.

What have I done:

  • Ensured that I, System and Administrator have access to all my local folders, subfolders and files in OneDrive.
  • That these folders are always available, and fully updated on my PC
  • Downloaded the latest Acronis, 11530
  • Uninstalled the old version??
  • Rebooted PC, and installed the new version of Acronis.

With Windowes 10 1803 and Acronis 2018, 11530: Still the same problem.

Can anyone suggest what I can do?

I don't think that a fall-back to 1709 will result in something different than that Acronis works OK again.

Chris, there have been several recent forum topics in this area, though this is not an issue that I have seen myself or encountered with my own OneDrive backups with the same system levels for the OS and ATI 2018.

See forum topics:

ATI Won't Backup OneDrive Folders to Cloud after Windows 10 April Update

Backup of OneDrive Folders Fails

Backup won't start - folder may be blocked by another app

I would recommend opening a Support Case direct with Acronis for this issue so that they can investigate this issue for you and other users.

I am getting a slightly different message (folder does not exist or is corrupt - suggest running disk scan), and the backup aborts.

I am having the same issue after upgrading to Windows 10 1803.  The error says: "Failed to back up file or folder F:\Onedrive': It may be blocked by another application", see attached image.   I closed all office applications and windows explorer but always get this error.  Any idea on what the conflict is?

Have a look at the last post in this thread - the solution there may work for you.
