I can sign into my OneDrive account with no error yet when the backup runs I get this:
ERROR: Error occurred during backup: The remote server returned an error: (401) Unauthorized.
Please, specify if you can sign in and add files to OneDrive.
If the answer is yes - please send logs to our support for further investigation.
Just an update in case anyone else encounter the same issue:
It is related to API limitations on Onedrive side. Uploads are being throttled due to the amount of data transferred.
What did you have to do to fix this issue?
[reply=“Mike;809”] What kind of files do you fail to upload? The main thing is to consider permissions for the account - check out: https://support.office.com/en-us/article/Permissions-needed-to-upload-files-in-OneDrive-for-Business-c0d770b2-5165-403d-9d58-62946bcf46dd
[reply=“Mike;809”] Since that is API limitation on MS side we currently can suggest modifying certain configuration parameters manually, that can help.
- close the Backup application
- open settings folder: C:\ProgramData\CloudBerryLab\CloudBerry Backup\
- find file enginesettings.list
- edit this file with notepad
- Find the string “10000000”
- change 10000000 to 2000000
- close and save the file
- restart the Backup application
- Reduce number of threads (Tools/Options/Advanced) to 1.
