Script to Run a Full Backup of a Specific Server to a Specific Tape.

I need help creating a script that will allow me to run a onetime Full Backup of a Specific Server to a Specific Tape.

Server Name = "DIGITAL1"

Tape ID = "DIG001L4"

Platform = "Solaris"

Policy Domain Name = "Solaris"

It is possible I may need to use multiple tapes.

I want this Backup to be an Archive Copy so I could always restore back to this data after however many years.
