Hi there,

I've read here http://www-01.ibm.com/support/docview.wss?uid=swg21608413 that
TSM for VE is using "content-aware" backup, if CBT is enabled. It also says
that TSM for VE will enable CBT after the first backup.

So I'm wondering if enabling CBT before performing the first backup would
make TSM for VE backup only the used blocks (i.e. used space) and hence
would save space on the storage pool?

Or would TSM for VE still backup the full VMDK, including possible lots of
unused space inside it on the first backup?

Regards,
Michael
