Backup CCTV Data 9 TB

Hi All,

We have a customer who is having 20 CCTV cameras.
So the daily data generated by the CCTV cameras (.avi file) is 300 GB.
It is storing it in Network Video Recorder right now.
They also have a tape drive which is connected to a server and is stand alone.
So they want us to take backup of this huge data on to a tape drive.
Also they want to compress this data by Backup Exec or any other method if it is possible

Thanks
Saurabh
