Installed Windows 10 Fall Creators Update - Now Local OneDrive Folder won't backup

I installed the Windows 10 Fall Creators Update yesterday on my computer. Backups are working on all folders apart from my Local OneDrive folder which contains only locally sync’d files.

The error is: Warnings: [ Failed to process path: C:\Users\Name\Documents\OneDrive\ => I/O error occurred.]

Duplicati is running as a service under Windows 10 v16299

Am running Duplicati -

I appreciate that this problem has been caused by the new version of OneDrive but if there is a workaround I’d love to hear about it.

It sounds like this is the same issue reported here:

I came here looking for info on this.

I use OneDrive with a paid 365 family subscription, and rely on it heavily. Since the Windows 10 update, I’ve been getting a LOT of failed backups, all with the same “I/O error” for all OneDrive locations.

Is there any kind of work-around we could try?

Had the same Issue. OneDrive Folder was not backed up.
After turning on the “expert option” Symlink-policy the backup works fine

Did you set the --symlink-policy parameter to store, ignore, or follow?

Just tried this with it set to Follow. All working correctly again

Thanks for the info.

I flagged your post as the fix, please let me know if that is incorrect.

Yes, that’s correct.
