Yes, but Time machine is still a local backup device... which few will
ever... despite good intentions ... remove from the premises.
When so many's essential biz is being done and stored on computer, not
having fail-safe backup is nonsensical. Determining the security of the
backup by the brand of backup drive that is sitting next to your
computer completely misses the point.
It's like going sailing over the Atlantic ocean with emergency flares
but without a life raft/ enough life rafts. Any backup, such as Time
Machine which occurs only locally, just ignores such real perils as
theft, lightning strike, fire, flood, earthquake and operator error.
Such short sighted backup solutions aren't really solutions at all ...
just falsely self-comforting hooey ... as so many on the Titanic paid
the ultimate price to learn.
Institutions are increasingly using incremental backup to drive
solutions similar in technique to the Time Machine but they are doing so
not only with redundant RAID backup drives but they locate the backup
drives remotely and those two aspects are the two most important aspects
of the setup.
Online backup may not be cheap enough for some yet (although S3 seems
pretty reasonable to me...) but my bet is it is the future of backup for
everyone but the largest institutions
I would be interested to know if anyone has experience with any other
than S3 ?

The nice thing about using a hard drive as backup media is that
incremental backups are consolidated (by copying new/newer files) into a
directory tree that is current and complete. Copying can be with or
without "replicating deletions" so that old stuff can be preserved in the
backup. The backup can be readily tested, since the files appear on an
ordinary hard drive. And it is quick to find and restore a single file or
two.
I'm looking forward to seeing how Apple's TimeMachine changes my backup
routine.
