Doug -
Apropos of your *original* point/question....
A Time Machine (unless it is offsite) doesn't solve the offsite
problem.
The overwrite problem doesn't solve *my* main problem which is NOT
catastrophic failure but operator error... perhaps one of the
options you mention in rsync, in fact solves it... though somehow
I suspect it is designed for *competent* people, not the rest of
us.
As for backups of backups, belts AND suspenders? I like the
Masahide (often attributed to his teacher, Basho) quote:
"Barn's burnt down, now I can see the moon"
Of course, don't expect me to be so philosophical next time my
hard drive (or worse, my Time Machine? or my house) burns down...
but it has a nice ring doesn't it? Better than "don't play with
matches!"
I also have to thank our own Morgan Thomas (on Discuss if not
FRIAM) who uses this often as her own tagline. And for good
reason.

It will overwrite files with the same name. You can
set with a parameter whether it will do a mirror-like sync or to
instead leave files that have been deleted on source directory on
the backup directory. To delete extraneous files on the
destination directory use the --del parameter.

No, the odds have
gotten me. I am assuming that rsync overwrites past
history, so it saves less than a time machine. Is that
correct?

1. Is
your 3TB drive off-site? Offsite backup
is the problem to be solved, IMHO.
2. I imagine that the probability that
your 3TB drive will be alive and
functional in a year is less than 99.999999999%
(not that I fully believe Amazon's
claims, but they do monitor their
disks and move the data when the error
rate hits a certain threshold).
3. If my data is off-site, I want
it encrypted. I'm not sure how to do
that with rsync. We do use rsync
nightly, however, to update our CTAN
mirror.

Just

there is a perfectly good way
to use rsync. Here's my
nightly backup script, which

My $.02 on Time
Machine.
I bought a 2TB
time machine about
4? years ago and
set up two MB
Pro's with it.
Other than a
little irritation
from accidental
reboots on the
device (connected
to the same power
strip as my flakey
motorola internet
service, yielding
a reboot via
powerstrip toggle
sometimes), I've
had nothing but
good look.
I've only had one
occasion to do a
full restore in an
emergency and it
worked like a
charm.. I *have*
used it to migrate
between MB Pros
and an iMac about
5 or 6 times in
the same period.
That has worked
flawlessly as
well.
It might be
prudent to back
that up somewhere
offsite, but I'm
just not that
prudent and now am
spoiled to my
regular "backup"
and potential
"restores" being
almost entirely
invisible to me.
I can't tell from
the discussion on
the list how
"transparent" the
true cloud
services are,
unfortunately I'm
pretty sure my
totally lame
internet would
make *restore* a
long and painful
experience.

I have one
data point. One
of our Macs near
Seattle had a
drive fail, so I
had an employee
take it to an
Apple store. The
'genius' was
very happy when
he saw the Time
Machine, and, I
think, nothing
was lost.
About the
depth of cloud
backups: I now
use Arq on the
Mac. The
backups are in
Amazon's S3,
and the
frequency is
settable: I
have one done
every hour.
You set a
limit on how
much space you
want to use --
just as a Time
Machine has a
fixed size --
and once you
hit that
limit, it will
overwrite the
oldest
versions as
necessary.
Also the paid
version of
DropBox keeps
at least some
history. For
saving a Time
Machine
offsite,
Amazons
Glacier
storage is one
cent a
gigabyte per
month, so your
150 gigabytes
would be $18
per year. They
really hit you
with transfer
charges if you
try to read a
large amount
in a short
time, but
since that
presumably
happens only
when your Mac
and your time
machine have
both been
roasted in a
fire, you
probably will
be happy to
pay them.
Unfortunately
150 gigs is
not enough for
most time
machines.
