I do a system backup like this once a week with S3. Documents (such as
PDFs/eBooks I've downloaded, which I don't care about encrypting) get S3
rsync'd every few hours.
I did a talk on this early last year at Surrey LUG, so it's a bit out
of date now:

The problem with Glacier is there's a really big delay before getting
access to the files again. I may not want to download data often, but
when I do, I'd like to be able to do a restore right now.
Currently S3 is costing me a few dollars a month for system backups
(it could be a lot less, if I could be bothered to tidy up old backups),
and Google is costing $20/year for 80GB of photo backups in Picasa.
That's well within what I'm happy to pay, so I don't feel a need to
switch to Glacier, except for use as possibly a secondary backup of
music, video and photos.
