For VMWAre backup: We have a VSA is the Vcenter too. Transport mode NBD. V10SP12
Regarding ISCSI drive mapped inside VMs, it is not possible to backup this drive (VSA is not aware mount point). So we had to install filesystem agent to backup these drives inside VM. (And no information about this in forums and documentations)
It will possible with V11 with the content awareness ? (Possible Exchange and SQL of course) In pre-requistes V11 installation, it is said the filesystem agent within a VM will be depreciated.
In this case we will have some issues if upgrading ?
Is there other solutions in commvault ? (I am still searching)
