Copy directly from Explorer to OneDrive online, no local copy.

[Carl-Fredrik Persson]

Hello,
I have 500GB of data on an external disc  ( X:\ ), Now I want to create another backup and copy this data from Explorer / Onedrive client to OneDrive online 

How do I do this without first getting a local copy under c: \ ... user \ ...? I dont want that!! 

I have marked the folder as online only but it will not work until all data is copied and I can only update the folder to online only.

My local hard drive currently has 30GB of free.

Probably overkill, it's an IT tool but I think it would do the trick, it's the SharePoint Migration Tool, certainly worth looking at for that volume of data anyway. It supports OneDrive for Business as a destination, just point it to the local folder you want to migrate. Where this may fall down though is it recommends 150 GB+ free disk space, unfortunately! You could try doing it in batches and see if that is plausible though someone else may have a better idea.
