I've been digging for the answer to this for a little bit now. If I back up a VM that has a LUN attached via iSCSI will the LUN also be backed up? It is mounted inside server 2012 as the "D:" drive. Thanks!
I am using VDP.
No it will not. VDP or any other backup tool you use to backup VMs (using the VMware API) will backup only the vmdk disks.
Best Regards
Completely agreed. It will not.
