TMG Backup Procedure

Hi Mates,

I am new to use Symantec Nebackup 7.5 product. I made some policies of taking backup of vmware virtual machines. All backup of VM's running perfectly except from the TMG running application. Is something wrong i do to take the backup of TMG or i must allow some ports on TMG to take the backup. Both NB server and TMG server are accessible to each others.

The error i got is VSS service, but when i looking of it, it's running perfectly. Any help related to TMG backup taken would be very helpful for me.

Regards,

Mohsin
