Errors OneDrive backup during incremental backup
From yesterday there are some errors during incremental disk backup. Yesterday it was a full incremental backup, today it was a daily incremental backup (attached log file)
After backup fails, I enter Acronis, so I can interact with a backup process via Acronis error message.
Attached find log file, error messages and an old document, explaining how OneDrive default location has been changed in 2019 (!)
Current Acronis Cyber Protect version: Build 39615

Dear friends,
I'm sure you have a lot of work, so week and a half without answer is not too much. I hope there will be answer some time...
The problem with Acronis is that no one can understand all these text lines in the log file when there is some problem during a backup. That's why I have to ask you for the help.
Suggestion: make error messaging simple and clear and there will be much less questions :-)
Regards,
Valery

Valery, the errors are being caused by including your OneDrive folder in this backup and having Files on Demand enabled to mirror those OneDrive files to the cloud.

Thank you, Steve
I have disabled Files on Demand and returned OneDrive to Acronis backup. I will see toady evening, but am sure it will help.
The most funny thing is, I do not use OneDrive at all! Thus, I did not enter settings after it has been installed along with Windows10 20H2 a long time ago and then all works fine. I think Files on Demand parameter has been enabled during one of the last OneDrive automatic updates and then my backup errors began
Have a nice weekend,
Valery

Hi, Steve
Now all is OK, thank you. Problem is closed
Just a couple of suggestions
1. I never understood, why some minor errors during backup must end a whole process. Example - my OneDrive problem. It might be a warning message and backup process might continue.
2. If there will be a real and serious problem during backup, backup process have to be aborted with an error (not warning!) message
3. And a last question. For those, who do not use Acronis MVP Assistant to look into backup results every day, why there is no Windows Notification Messages if Acronis backup finishes with errors?
Thank your very much for your help!

I have solved my issue by removing and then add again the service.
