vmware esxi - Veeam backup iSCSI drive - Server Fault
https://serverfault.com/questions/455918Veeam 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.
