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
