I am using Duplicati since quite some time now - Great Piece of Software! (actual version 188.8.131.52)
So i thought it would be a good idea to backup to “OneDrive for Business” to have another backup (besides local Backups).
I created a new job:
Server and Port: yyy-my.sharepoint.com
Path on Server: personal/xxx.xxx_xxx_de/Documents/test (/test is a folder i created online, so it really exists)
When i Click on “Check Connection”: check runs with success.
But when i run the job:
For about 30 secs "Verifiying “Backend-Data” is displayed and then an Error:
“Access denied”. You have no permission to access the ressource" (translated from non english version, so Message might sound a little different)
“Microsoft.SharePoint.Client.ServerUnauthorizedAccessException: Zugriff verweigert. Sie haben keine Berechtigung, diesen Vorgang auszuführen oder auf diese Ressource zuzugreifen”
In office-portal i checked if the user has write access: yes he has (he is also the owner)
What goes wrong?
Also, i havent found any FAQ regarding Backups to Onedrivefor Business. Is there any?
(Best thread i found so far is Duplicati 2 + OneDrive Business )
Thanks in advance for any hints or ideas how to troubleshoot further!
