Hello @IT Admin Thank you for reaching out to us on Microsoft Q&A platform. Happy to help!
Short answer: Azure backup doesn't support backup of OneDrive and SharePoint directly. Here is a feedback item - https://feedback.azure.com/d365community/search/153aa817-0725-ec11-b6e6-000d3a4f0858?q=onedrive you can up-vote with your requirement to relay the same to the product group.
However, you can back up a SharePoint farm to Azure with MABS - https://video2.skills-academy.com/en-us/azure/backup/backup-azure-backup-sharepoint-mabs#:~:text=Restore%20SharePoint%20Database%20from%20Azure%201%20To%20recover,Recatalog%20status%20window%20opens.After%20cataloging%20is...%20See%20More.
Not sure, what type of backup you are using. Appreciate if you could share more details about the backup service you are using.
FYI: The list of services that you can back up using the Azure Backup service.
On-premises - Back up files, folders, system state using the Microsoft Azure Recovery Services (MARS) agent. Or use the DPM or Azure Backup Server (MABS) agent to protect on-premises VMs (Hyper-V and VMWare) and other on-premises workloads
Azure VMs - Back up entire Windows/Linux VMs (using backup extensions) or back up files, folders, and system state using the MARS agent.
Azure Files shares - Back up Azure File shares to a storage account
SQL Server in Azure VMs - Back up SQL Server databases running on Azure VMs
SAP HANA databases in Azure VMs - Backup SAP HANA databases running on Azure VMs
