OneDrive / Sharepoint - Bad performance

[opetit]

Hi,

I am testing Veeam Office 365.
We have 1Gb fiber and do peering directly with Microsoft (we are an operator).
The backup of a mailbox is done at 10MB / s and the bottleneck is the source (rather correct)
The backup of a OneDrive or a Sharepoint site is done below 300 KB / s and the bottleneck is the target...

The repository is the same for the 2 jobs (so I don't really understand the bottleneck)

I added 10 backup accounts for Sharepoint. No difference...

Are there any other limitations?

My support case number is 04358818.

Regards,

Hi opetit and welcome to the Community!

Additional accounts help to release throttling impact on backup performance, which would have been seen as a source bottleneck. They cannot speed up writing the data to the repository.
In terms of saving the data to a repository database there're no limitations that might affect the rates.
