Yes, you can add the Raptor to the backup job, or create a separate job.
That media kit is just that - a CD. It does not include any licensing. You MAY be able to find a tape drive that comes with software that will do the job, but to buy something like Backup Exec with the required licensing will be in the 700 buck range. As I said, backing up a server is never cheap, it's just the way it is. It's just like other utilities - Partition Magic is under $100 for example, but it won't run on a server OS, you need their storage manager software for that, and it's hundreds of dollars.
