SQL Database wont backup

Hi Community,

I am trying to backup an sql databse on windows 7 client from windows server 2016 master. When I run the job manually I get 2 jobs on activity monitor as shown below:

On Sql client agent I see following output:

INF - BACKUP STARTED USING
Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (X64)

This is my script file:

OPERATION BACKUP
DATABASE "myTestDB"
SQLHOST "client server"
NBSERVER "master server"
MAXTRANSFERSIZE 6
BLOCKSIZE 7
NUMBUFS 2
ENDOPER TRUE
VDITIMEOUTSECONDS 900

I have created following log folders:

On client: bpcd and dbclient
On master: bprd (restart NetBackup Request service after creating log folder)
On media server: bpbrm and bptm

and my media server properties looks like this:

 After changing timeouts and adding VDITIMEOUTSECONDS 900 I have also restarted media, master and client services. 

Can anyone please help me figure out what's going on here? Stuck on this since long time. I am able to do backup of files from the same client only sql isn't working.

thanks!
