TSM for ve 6.4, tsm server 6.2.5 on RHEL 6.1
Data movers on RHEL 6.1.

Ran our first backup of a production vmware host.
We thin provision our vms.
One is provisioned at around 1 tB.  However, according to our vmware admin, it 
is using only around 238 gB of disk at this time.

When we ran the backup, It appeared to back up the entire 1 tB of something.
The schedule for the backup is below.
Is this a limitation of the product, or simply misconfiguration.
TSM I can deal with, vmware, I know little about.
Any pointers to good reference info would be appreciated.

I have looked in the TSM for ve users's guide, but don't' see anything.
