Backuping up raw device mapped disk attached to a VM client
I need some knowledge: I'm using Netbackup 188.8.131.52 on Windows Server 2008 with a master and 2 media servers that are my VMWare backup hosts. I. - Backing up VM's with attached RDM disk: I've read the VMWare and snapshot client documentation but I'm still a little unclear about how to backup RDM (raw device mapped) disk. From what I read, I have 2 options: 1. - Install Netbackup client within the VM and backup the VM as I would a physical server. (not preferred.) 2. - Create an alternate backup client that has same OS and patch rev (or higher) that has access to the RDM to utilize offhost snapshot backups. My questions are: a. - Why can't I backup the RDM disk with a VMWare policy? b. - Can I backup the OS filesystem with a VMWare policy and the RDM disk with an alternate client so I can utilize offhost snapshots? c. Are there any differences if the RDM disk is physical or virtual?
