There is already a similar question(and 2 solid answers), but mine is a little bit different.
Suppose you create a 5-volume archive + 3 recovery volumes(.rev files). This is supposed to reconstruct up to 3 of any of the original volumes. So far, so good.
But it also seems possible to reconstruct any one of the volumes even if you are missing any 2 of the 3 .rev files.
How is that possible?
IOW, how is it that any single one of those .rev files is sufficient to reconstruct any single one of the 5 volumes?
