The only difference is that, with RAID, disk failures/ redundancy is handled transparently, and file-servers can be configured to do what you did out of the box (except for the tape backup). Today, the hourly and nightly backups are done so that people can recover from human (mostly their own) mistakes. Also, it is good advice to store your weekly/monthly backups in a different physical location.
