I wish btrfs wouldn't use the old school micro-managing storage terminology (or only as aliases) and instead let you set the goals. What people really mean is that they want their data to survive the failure of N drives - exactly how that is done doesn't matter. It would also be nice to be settable as an xattr on files and directories.
