I just want to know when Netbackup SQL agent takes the backup of live database,then it creates asnapshot of database and then take backup of that?

Depends.  Normally it does stream-based backups.  If licensed for Snapshot Client and properly configured then you can do snapshots.

You have asked previously what happens during SQL backup.

@WR:So if not configured for snapshot client ,then how does it takes the backup?

One virtual device is created per backup
stripe. In addition, a VxBSA session is initiated for each stripe. These separate
sessions allow NetBackup to start a backup job for each stream that is generated
from SQL Server.
Where this virtual device is created?On the drive where this database is located?

I don't know details of how Microsoft handles that.  Best to ask on SQL Server forum.
