Microsoft SQL backup for Backup Exec 2012

Hi All,

    I am new to backup Exec 2012. I am trying to take the Microsoft SQL Backup with different options available with respect to consistency check(full checkup including index, excluding index, and physical media).

 Can anyone guide me about the steps to how to proceed with each options in SQL. Also should i need to install any agent in order to take backup.

Thanks in advance.
