(DP) support tip: DP vmware backup using transport mode HOTADD

A few things to check when configured to use HOTADD transport mode..

1. HotAdd transport is supported only on a virtual machine backup proxy
   (refer http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1035096)

2. no anti-virus should be running on backup proxy host during the backup

3. automount should also be disabled on windows backup proxy host
