Testing VE 6.4 on TSM server 6.3.2 Win2K64.  ESX hosts are VSphere 5.

So on the first VE backup we see as expected:

12/10/2012 05:18:22 TSM for Virtual Environments TDP VMware 6.4.0.00
12/10/2012 05:19:01 ANS1711W Incremental backup selected for 'HHHHH', but a 
Full backup has not yet been performed. Performing a Full backup instead.
.
Then we see
.
.
12/10/2012 05:20:14 ANS9384W Unable to get VMware Changed Block Tracking(CBT) 
data for virtual machine 'HHHHH'. Full VM backup continues, and includes both 
used and unused areas of the disk.

The "unable to get VMWare CBT data" is also expected on the first backup.  But 
I thought with VE it was supposed to be smart enough not to include unused 
areas of the disk?

We've checked with show VM all:  CBT is enabled, and subsequent backups are 
true incrementals.
We've also tried blowing the filespace away and starting over with the same VM, 
same results.

The problem is that these are thin-provisioned disks.
When you get this first full including all the unused space, then when you 
restore the VM, it comes back as full sized, no longer thin-provisioned, with 
the possibility of blowing out the datastore and causing a nasty outage.

Anybody got a solution?
