You can not backup running vm virtual machines one a esx box by backing
up the linux side of the esx box.  The only way to backup them up via
netbackup is to purchase a license for each vm virtual machine.  
In your example of "10 linux vm virtual machines and 10 windows vm
virtual machines" you will need 10 linux and 10 windows licenses for
netbackup to back them up.

We have 8 esx servers running here and some I use esxranger to back them
up but most of the virtual machines we want file level restore
capability so we had to purchase the netbackup licenses.

Yes, but...   If you have 10 linux virtuals and 10 windows virtuals
running on a single VMware on linux system, how many NetBackup licenses
do you need?

The prevailing wisdom on the list seems to indicate you need 1 linux
license AND 1 windows license.

To put it more plainly, in the example given, 1 linux license for the
base system is insufficient, and 20 licenses (10 linux and 10 windows)
are not necessary.

If anyone else can corroborate this I'd be glad to hear it.

Austin
