As I understand it, HFS+ can silently corrupt your data; so, Time Machine could potentially propagate that "corrupt" data all the way through your backup disks (and possibly wipe out older, "correct" data!)

We need integrity checking both at file-system level and at backup-solution level. If I'm not mistaken, with Time Machine on an HFS+ volume, we don't have the former, and the latter is file-based and not block-based (making it not very efficient, space-wise).
