Why each option
The Tower of Hanoi is a tape backup rotation scheme that staggers backup sets across multiple tapes using a logarithmic pattern to maximize media coverage and recovery options.
High RPM drives are a performance specification for spinning hard disks and have no association with backup rotation schemes.
The Tower of Hanoi is a well-established tape backup rotation strategy that uses a mathematical sequence to determine which tape is used for each backup cycle. It minimizes the number of tapes needed while maximizing the range of recovery points available. This scheme is specific to sequential media like tape, not disk-based storage.
External storage is a broad category of storage attachment and does not describe any specific backup rotation methodology.
RAID is a disk redundancy and performance technology that operates in real time and does not involve scheduled backup rotation schemes like Tower of Hanoi.
