Hello ,
You will need SCV SnapCenter Plug-in for VMware vSphere to be installed to backup your VMs and also the SQL databases on VMDKs and RDMS
With the latest version of the software the VMS are backed up using SCV Plugin and the backups are maintained on the SCV plugin host database(MySQL) and not on Snapcenter server
Use the SnapCenter vSphere web client to perform data protection operations for VMs, VMDKs, and datastores. All backup operations are performed on resource groups, which can contain any combination of one or more VMs and datastores. You can back up on demand or according to a defined protection schedule.

--------------------------------------------------------------------------------------------
SQL databases VMDKS and RDM luns still use SCV to backup data but the backup data is stored on Snapcenter server database (MYSQL)
If your database is stored on virtual machines (VMs), or if you want to protect VMs and datastores, you must deploy the SnapCenter Plug-in for VMware vSphere virtual appliance.
If you are using SnapCenter Server to protect SQL databases that reside on VMware RDM LUNs or VMDKs, you must deploy the SnapCenter Plug-in for VMware vSphere and register the plug-in with SnapCenter. The SnapCenter Plug-in for VMware vSphere documentation has more information.
