SCV, will only provide Crash & VM-Consistent Backup : Crash consistent by taking a snapshot of all the data found on a disk at the exact same time without any awareness about the underneath file-system. VM consistent backups will provide file-consistent backup with the help of "VMware Tools to quiesce the VM file system" here MS VSS come into picture. However, it is still unaware about the Applications(DBs Pending IOs).
To ensure SQL DB is consistent (hosted inside a VM), there must be a application-aware components such as SCSQL (Which coordinates with MS VSS), inorder to pause & and flush the in-transit/pending IOs to the disk, before the application-aware consistent backup is taken.
SnapCenter Plug-in for VMware vSphere, works with SnapCenter Server to support application-based backup and restore operations in VMware environments for SnapCenter application-specific plug-ins. Therefore, plug-ins for respective Applications(Databases) are necessary. The Plug-in for SQL Server automates SQL Server database backup, verification, restore, and clone operations in your SnapCenter environment.
