I am trying to set up my Nonprofit Office 365 with Duplicati in OMV where backup from my Odroid goes to Sharepoint. At first, I chose Sharepoint (not v2) and entered my credentials and the site and everything, and the test connection went fine. But there were errors when backing up. Someone in a forum suggested migrating to Sharepoint v2. But I can’t get that to work either. There is a bug where my old username and password are in the destination url, so I copied it, edited out the username and password (and left the oauth) and imported it back in. I’m still getting “Failed to connect: No site ID was provided.” I tried deleting the whole backup and starting over, but no dice.
In “Destination path,” I have tried mysite.sharepoint.com/test/ as well as mysite.sharepoint.com/test and https://mysite.sharepoint.com/test/ and https://mysite.sharepoint.com/test and just /test/ and /test and test. Nothing I put in there will work!
--site-id (String) ID of the SharePoint site to store data in. This parameter is required when using the relative document library path (without specifying the SharePoint site’s web address). This ID can be looked up by querying in the Microsoft Graph Explorer. When the SharePoint site’s full web address is provided, it is looked up automatically.
Then in Duplicati, for Destination path, I just put a name for a folder that I want all my backup to go into, and added my AuthID. Under Advanced Options, I chose site-id, and pasted the site ID that I had copied from the Graph Explorer.
