Backup New Added Files From Folder to Tape

Hi all,

I am new to BackupExec 2010 R3!

We have a folder on our server that SQL Server backups there. I need to introduce this folder to BackupExec so it picks up files from that folder to write them on the Tape. But I want each time the agent of Backupexec runs, only write new files found in the folder. Is that possible? or BackupExec will write whole contents of folder to tape each time?

I would be grateful if someone could give a solution.

Many thanks in advance,

Amin
