Not a bad idea. Personally I have taken to keeping copies of my most critical — and potentially costly — data as well as current project files on encrypted backups in iCloud or Dropbox. In my case that offers the advantages of:
  • Continual instead of periodic backup
  • The data is available to me literally anywhere in the world
  • It keeps the data on my Mac mini, iPhone, and iPad continually synchronized
  • Apple and Dropbox have a far better backup systems for my data than I have.
Of course thoughts of a Thunderbolt RAID 5 array do flick through my mind occasionally. cool

If we knew what it was we were doing, it wouldn't be called research, would it?
