    You cannot perform a VMware type backup with RDM. 

    This is a VMware limitation. You will see in VMware GUI that the snapshot is disabled.

    The only way to backup a VM with RDM is to install NBU client and backup with relevant OS or DB policy.

Hi Rahul, 

yes if it is a VM, restore always happen through ETHERNET. you cannot setup SAN client for a VM unless if you have vHBA but this is not bestpractice

But when backup happens through SAN ? why it cannot be vice-versa. I always thought Backup and Restore follows the same flow ? 

Say i am using VADP to backup my VMDK disk and snapshot is taken at vserver level and data is sent to Media server through FC but when i restore why is it not flowing backup using FC ?

Thanks, 

Nayab

Hi 

What restore are you trying to do ? is your media server is appliance or Windows server  ?

if you restoring VM using applaince it will restore via FC, if its windows you must bring the LUN online in device management.

GRT restores for VM always restore via LAN.
