We have an ESXi virtual machine currently being backed up using Veeam B&R 6.5.
The virtual server itself has an ISCSI drive attached (Windows iSCSI Initiator), but it is not included within the backup job (only the C:\ drive included). Can someone please tell me how I can add this iSCSI drive?

Veeam B&R utilizes VMware's backup APIs in order to provide backups of virtual disks. It is not a generalized host backup product, and it cannot take backups of guest-mounted iSCSI volumes.
If you want Veeam to back up this drive, you'll need to attach it as an RDM (Raw Device Mapping) in Virtual mode from the hypervisor side instead of attaching it via the guest iSCSI initiator. Note that you cannot use Virtual mode for a disk used in Microsoft Clustering Services.
