   9 # Explaining this whole thing. The host amy is used by someone else,
  10 # i back it up to my extra big partition on one computer.
  11 # But I also want to restore it and test out the restoration on
  12 # a computer I usually use. For this, I created a separate partition
  13 # that has the amy encryption password, and a separate boot so
  14 # that I could encrypt my own boot partition if I want. Then,
  15 # I backup from this big partition into that partition in order
  16 # to boot and run it.
