Diskless vm option enabled in policy vmware tab advance option

Hi All,

My backups are failing with below error and I found link on google : http://www.symantec.com/connect/forums/cannot-snapshot-sles-11-sp2-netbackup-7601

I enable diskless vm option in policy vmware tab in advance option and backup working properly. I want to know is this solution is right.
