0. Write the data on an hard disk (named 0) and calculate multiple hashes for the various fragments of data. The hard disk must contain also a minimal os which is only able to dd partitions and must be connected to a computer

1. Create some type of mechanical which is able to periodically do these tasks:

   - create an hard disk (named n)

   - plug it to the computer above

   - transfer the data from hard disk n-1 to hard disk n

   - check the hashes

   - unplug hard disk n-1

   - reboot the system using the new hard disk

To minimize the failure rate of this environment you should create more computer which check if something is not working
