Hi Simon.
NetBackup for VMware does not backup devices that are accessed via Raw Device Mapping (RDM). Most RDM-based storage is configured in VMware’s “Physical Compatibility Mode”. In this mode there is no way to create a snapshot of an RDM device.
We suggest using a client to backup storage that is configured this way. If the Enterprise Client is used, advanced backup methods (e.g. off-host backups of mirrored storage) can be employed with VM backups and RDM’s.

Subject: [Veritas-bu] Restore of VM that has RDM's - missing after restore
I may have missed something here, but wanted to check...
NBU 7.0.1 and doing full VM Backups, most of which have RDM's
I ran a test today on a VM Guest that has a single 10GB RDM. Performed the VMware Backups (Using the windows-flashbackup policy) and all fine.
Using the BAR Tool, I see the VM Guest which is fine and I am NOT expecting the RDM to be present, so I fully understand this!
But when I restore the VM (Overwrite the existing VM, use the same UUID, power on VM), this works great but the RDM that was mapped is no longer mapped.
Now, I thought that by capturing the VM Guest, it meant that any RDM that was assigned would get re-attached once the VM guest was restored.
Or have I missed the point?
