I’ve noticed that if I start with a small backup set, that I don’t get this error. If I grow the size of the backup set by adding files/folders into the configuration, then I don’t get this error. However if I add too many files, or too much data to the backup set then I start getting this error again.
I’m not clear on whether the problem comes when I add too many files, or too much in terms of the volume of data, or if its time elapsed sending the data to OneDrive, but I felt it important to post my findings.
So I think i’ll be able to grow to the full size of the data that I need backed up, but its a problem that I have to manually grow the backup set (200 Gig in chunks is likely to be a lot of chunks!)
Please let me know if there is any other information you would like me to test for, or logs I can post.

As i wrote, i am trying to upload 16GB of several folders. I tested same way - manually increased backup set by adding folders- only difference to **greg.ewing** is that it collapsed everytime. I tested changed order of uploaded folder, still same.
On Onedrive Bussines in company it works nice, also tested with recovery from backup.
Just onedrive personal it doesnt work as expected

I started looking into this yesterday, but didn’t have a comment until today’s similar ending. I suggest:

OneDrive also has a somewhat short timeout of 100 seconds, and I wonder if the work link runs faster.
[–http-operation-timeout](https://duplicati.readthedocs.io/en/latest/06-advanced-options/#http-operation-timeout) can increase it, if that turns out to be the problem (the logs above may reveal).

So I gave it a few months and I tried this again and it has been working flawlessly for the past couple of weeks.
I’m mystified as to what changed, I’m only sorry that I didn’t see the reply above until now as I may have been able to provide some interesting diagnostics.
