Hi everyone,

We are using Networker 7.6.2 to backup our VMware virtual servers using VADP.  
Due to our DR setup, we perform full backups of our VMs every night.  I say 
that because while I was investigating use of space on our VMs (to see of the 
amount of space being backed up could be reduced), I talked with our VMware 
Admin and he told me a lot of our larger volumes of virtual servers are thin 
provisioned.  It was his assumption that these volumes that are thin 
provisioned would only backup what was being "used" rather than the entire 
volume of space of the drives.  What we found was thin provisioned space is 
backed up just like thick provisioned space...the entire volumes are backed up 
regardless of thin or thick provisioning.

Has anyone else seen any information about VADP backups with Networker 7.6.2 
and thin provisioning with VMWare?  If it is in one of the 10 guides I need to 
"RTFM", please tell me which one I need to read and I will gladly do so as I 
have been unable to find it.

Kevin
