We are seeing "The request uses too many resources." warning on four different SharePoint lists. They warn with the same message on each job run and have not been successfully archived. Our tenant did verify that these are large lists, but did not notice any other commonality.
The warnings appear in the UI as:
[Warning] Processing site https://XXX.sharepoint.com/xxx/xxx finished with warning: Failed to backup list: XXX
XXXX, The request uses too many resources.
and the logs show:
8/28/2018 9:06:49 PM 74 (1580) Server error of type Microsoft.SharePoint.SPException occurred: (-2146232832) The request uses too many resources.

Veeam support (case #03166798) suggested the following:
Unfortunately Office 365 Support is pushing back saying that they can't help with third party applications.I've done some cursory research on this, and it appears to be related to a limitation on the Microsoft side, possibly with two values: "MaxResourcesPerRequest" and "MaxObjectPaths"
My recommendation is that you reach out to Microsoft Support for assistance on troubleshooting things further.
Anyone else seeing this error with large SharePoint lists?
Any suggestions on how to get o365 support to actually check/adjust these settings?
