DPM 2025 failing with SharePoint Subscription Edition

I recently upgraded from SharePoint 2019 to Subscription Edition.  I was able to back SP 2019, but not the new version.  It gives errors such as the following:

Retry the operation. If backup is failing for a SQL instance or Sharepoint Farm, make sure SQL OLEDB driver version 19.3.3 or higher is installed on protected computer.

I have tried both 9.3.5 and 9.4.1 of the OLE DB drivers without success, on both the SharePoint and SQL servers.  In the past, I only installed this driver on the SQL server.  I believe there may be some incompatibility with OLE DB 9.4.1 as with it installed the non-farm related databases also fail intermittently with this message, but not with the 9.3.5 driver.   I'm using SQL Server 2022.  Both DPMRA and SYSTEM have sysadmin roles on the SQL server.

Anyone having this type of problem?

    Hi,

    OLEDB Driver 19.4.1 on SQL- DPM and WFE Server work fine to protect Sharepoint SE Farms.

      Maybe for you, but not for me.  It also fails for non-farm SQL databases as well.  I've had a support case open on this for about 5 months now to no avail.
