Hi 

You should backup sql server by netbackup for sql agent.

If you want to backup database files,you can stop sql server first ,then backup all the data files.

[Marianne · Accepted solution]

You need to exclude SQL data file (*.mdf, *.ldf, etc) from MS-Windows backup.

Use NBU agent to backup SQL databases or else SQL built-in backup tool to backup databases to disk which will be included in MS-Windows backup.

[Shoeb_Sayyed]

Dude, Files are in use at the time of backup. stop the db before taking backup, or use NBU agent to take SQL backup.

[R_Sathish_Kumar]

Use Netbackup SQL Agent utility to take Microsoft SQL server databases.

[Michael_G_Ander]

If you do not want use the SQL agent for some reason, set up a maintenance plan in the SQL server to run backup to disk and backup the resulting files with Netbackup.

Cannot recommend it as you get a more complex and probably longer restore/recovery process
