Tower of Hanoi Schedule: the Strategy of Data Backup RotationTower of Hanoi backup strategy, named after the classical Tower of Hanoi puzzle (which consists from moving eight disks between the three spines, with no larger disk put over a smaller in a single spine), is a method originally used for backup tape rotation, but now it is a much more common backup method.

Any equal quantum of time can serve as a base instead of a “day”, e.g., a minute, a 10-minute interval, a Sunday or a three-month period. Here, the term “day” is only for illustrating the basic principle. Note: As compared to Grandfather-father-son rotation schedule, this one can employ more backup media sets and save a deeper backup history. This backup rotation schedule requires only five backup media sets to perform daily backups during a month, for instance. ![]() Recommended Solution![]() Version 8.4.6, built on April 25, 2023. 116 MB Handy Backup StandardThe simplest Standard edition for home users fully supports all components needed for the Tower of Hanoi backup strategy, allowing saving data to three or more storage sites. Implementing the Tower of Hanoi Backup Method in Handy BackupTo create an automatic implementation for the Tower of Hanoi backup strategy, you must make some backup tasks in a New Task Wizard, with each of these tasks copying the same dataset. Here we are providing an instruction for the “four-tower” set. Please follow the next necessary operations:
Note: For all tasks of the Tower of Hanoi backup rotation scheme, always mark the “Use advanced mode” option on Step 1. Without this option, you cannot get access to some principal features! ![]()
![]()
![]()
![]()
![]() These are all the operations to set up a Tower of Hanoi backup system in Handy Backup! You can select any preferred scheduling period instead of days, and you can add any depth to this algorithm by using powers of two for an initial interval between tasks and the doubles for this interval for repeat. How the Tower of Hanoi Backup Strategy WorksEach additional backup media set added to the rotation doubles the deepness of backup history. The program uses it only when the previous sets are not in use. Thus, the later a backup media set is added to the history, the older files it stores and the less time a program will use it. Caveat! The Tower of Hanoi backup schedule enables one to have a deep backup history, but does not allow storing many recent backup copies, as a daily backup is erased in two days, for example.
