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?

I am not paranoid, the odds /are/ out to get you.

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 curious why you Mac guys are buying backup systems,
when there is a perfectly good way to use rsync. Here's my
nightly backup script, which currently sends my nightly
incrementals to a cheap 3TB USB3 external drive:
#!/bin/bash
# Just in case they are not mounted
/bin/mount /mnt/3TB >&/dev/null
/bin/mount /mnt/Movies >&/dev/null
/bin/mount /mnt/Video >&/dev/null

echo "Starting /home/roberts backup" >>/home/roberts/backup2.log

/usr/bin/rsync -vurltD
--exclude-from=/home/roberts/.rsync/exclude /home/roberts
/mnt/3TB >>/home/roberts/backup2.log 2>&1
echo "Completed /home/roberts backup"

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.

So has anyone successfully restored an entire system
from the Cloud (or a Time Machine come to think of
it)? How easy was it? Any statistics on success rate?
