It does if you're using a separate disk. :-) It doesn't, of course, cover the

why there's no support for multiple, redundant backup disks.

On OS X, TIme
Machine is fantastic. It's actually brilliantly simple; it just makes hard links to
the files for each iteration (except the modified ones, which it copies) so that you have
a working image for each backup that is indistinguishable from a non-incremental backup
(and the hard links only take up the space of an inode each). It's so simple that
I'm surprised I'd never seen it anywhere else.

Hmm, but it doesn't save your ass on harddisk failures. :-|
It is still a nice feature.
