Does anyone have what they consider to be a good NBU database backup script?

I've tried to write a script to do the following, but have been unsuccessful:

1. Swap in a new DB backup tape daily
2. Protect the OLD DB backup tapes from use
3. Backup the database on demand (whenever the script is run)

Does anyone have a good script for this?
