      Relying on physically moving a disk isn't a good backup/recovery
      strategy.  Disks are the least reliable single component in a
      modern computer.  You should figure out the best file system for
      your application, and separately figure out a recovery strategy,
      one that can survive the failure of *any* component in your
      system, including the disk itself.

    
    This is why I use a RAID array of 10 disks. So there is no single
    point of failure. What else could I do? (Yes, I can make regular
    backups, but that is not the same. I can still loose data...)
