If you're referring to Veeam itself using different DB back-ends in the VBR servers, you can't do that if you're using Veeam Backup Enterprise Manager. All of your VBR servers must be using the SAME database back end as VBEM, you can't mix and match them. Unless that's changed in 12.3.2, but it was that way as soon as they introduced PostgreSQL by default. I bumped into this when I installed a fresh VBR server because I wasn't paying attention on the installer and it chose to use PostgreSQL and I couldn't then add it to my 13 other VBR servers in VBEM due to the database mismatch. Luckily, I hadn't started doing a lot of configuration on it so it was easy to burn it to the ground and re-install, but that's a definite limitation.There are plenty of applications that support choice of database back-ends (including Veeam B&R for the moment). You could have PostgreSQL on Linux and still allow SQL Server on Windows.
