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...)
