Such as "single" as in > one file is really on one disk and thats it. What I'm dreaming for: I have a bundle/cluster of (p.e.) 3 disks. When I remove 1 disk (accidently/planned/because of disk failure) then I'd be very pleased when the contents of the other disks is (mostly) still readable. It's no fun restoring Terabytes ... Yes - I know: that's no backup, that doesn't replace a backup. Viele Gruesse!
