Duplicati 2 + OneDrive Business

To be more specific for anyone struggling, @kees-z 's solution worked for me, but the specifics for what I had to enter for the domain-my and name_domain_com fields was a little ambiguous.

If you go to the online OneDrive Business page, then look at the URL, you will see something like

https://domain-my.sharepoint.com/personal/name_domain_ac_uk/_layouts/15/onedrive.aspx

From this, you can see exactly what you need to enter.

(In my case it was ac_uk, not com, because I’m a UK University student)

Additionally, it’s extremely important you ensure the end of the ‘Path on Server’ ends with Documents/FOLDER_NAME, I omitted the Documents directory, but if you miss this out you will find the files will upload without error but disappear to the ether! I just wasted over 24 hours uploading 500GB on a 20Mbps connection only for all the files to be missing because I missed the Documents text. ‘Documents’ is infact the root of your OneDrive.

Hello everyone,
after some time I’ve finally found the lost backups on Sharepoint. Even though I tried to save it directly to the enterprise Sharepoint eg. https://tenant.sharepoint.com/web/our_page/Backup/backup (where Backup is the name of Document library), Duplicati created another folder and structure in
https://tenant-my.sharepoint.com/personal/my_email_adress/_layouts/15/onedrive.aspx?id=%2FShared%20documents&listurl=https%3A%2F%2Ftenant%2Esharepoint%2Ecom%2FShare%20documents.
