Exchange 2013 SP1 IP Less DAG (no CNO)

Dear All,

I was referring to this KB - http://www.symantec.com/business/support/index?page=content&id=TECH218366

Which is telling me backup exec will not work if I have Exchange 2013 SP1 with IP Less DAG. This is a big surprise to me because is vendor is telling that new feature is not supported. I could see Symantec gets the product update before the release of it but the backup exec was not update even after few months of Exchange 2013 SP1. 

Does it mean we should stop using backup exec and look for other backup options?

or

Should we expect a hotfix sooner.
