In simple terms, NetBackup says to SQL server - give me some bits! It's up to SQL server to provide the right bits in the correct order. NetBackup server functions as a scheduler (when to run) and media manager (where to put the bits).

Please answer these questions:
Using which backup method?
What have you tried so far to find this answer?
If using the NBU agent - have you tried reading through chapter 1 of the NBU for SQL manual?
(I know that you have this manual because you posted questions before).
If you did, you would see this topic in the manual:
How does NetBackup for SQL Server back up a database?

SQL agent method.
I have read the manual.But it is not clear.
My doubt:When the SQL is not going down,then how the backup is consistent?

Please tell us what EXACTLY do you NOT understand about the second paragraph under this topic in the manual:
How does NetBackup for SQL Server back up a database?
If you don't understand the parts happening inside SQL, best to speak to your DBA.
Or just accept that the agent 'knows what to do'!

Lets break that up into small pieces:
When a backup script is executed, NetBackup for SQL Server does the following:
- generates an SQL backup statement,
- logs into SQL Server, and
- delivers the SQL statement to SQL Server through ODBC.
- Next, the database agent connects to SQL Server through one or more VDI objects.
- 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.
