Oh that's funny.  Hopefully the folks on the DataSafe side are more
competent.  Not that I would entrust online backups to an opaque
service and proprietary, closed source client software.  Even assuming
there are no bugs and everything that should be encrypted is encrypted
before being sent out, the fact of the matter is one may never know
whether that encrypted data is compromised and if so by whom.  IMO
one should operate on the assumption that the encrypted data *will*
be leaked, and therefore it needs to be extremely strongly encrypted
so that it "cannot" be decrypted using not only today's powerful tools
and techniques, but tomorrow's and far into the future.  In addition to
the potential for compromise there is the reality of backups which are
totally beyond one's control.  One can *never* reliably delete the
data caught up in such a backup.  Such things may not be an issue for
some users, but given there is no going back, all should be very very
thoughtful and carefull when it comes to this sort of thing.

Sure it's free.  They're just giving you $9 off if you opt not to make them
reserve the storage space for you.

You might be a big looser who, say, has eleventy billion terrabytes of
personal storage on your home network.

Not that there's anything wrong with that or that you personally know anyone
even approximating that description.

I saw an ad on TV for a Dell desktop system, and they included as one
of their "features" that it comes with a Free Trial Version of
anti-virus (I forgot which one).
