This issue has been addressed with a Hotfix
GRT backup's don't seems to discover extended partitions on VM's(though it seems to backup it internally in the .vmdk file). It used to work and then suddenly stopped working. Is critical for us to get it resovled asap. Thanks.
If you have not yet, I would suggest calling in and opening up a case so that we can make sure to get you the fix for the issue as soon as it's released, if not before. The hotfix we just released (162830), did help out a few customers that I have talked with about the issue but not all of them.
Note: we are still looking into the issue, so there is no ETA for delivery at this time

Thanks Ben. Initial quick testing reveals that the hotfix fixes the issue. I will report back if further intensive testing reveals otherwise.
