For sure.  But I don't have anyone pushing 10 GB nightly :-)  It's just that
people were telling me to go buy a hard drive for 150 MB/day, and I wanted to
point out that for many people that's ridiculous.

I trust Amazon more than a HD.  You're free not to, but I've seen more HDs fail
than I have Amazons.

Which, if you multiply it out, is more than $3.

(2 minutes * $20/hour * ~20 days/month) / (60 minutes/hour) = $13.33

Uploading to a remote server is more automated (client doesn't even have to
*think* about it), and for low amounts of data, is cheaper.

For the record, JungleDisk uses AES-256.  My bigger worry with one client is
that they refuse to use good passwords, despite my best advice.

Oh, and I bet if I pointed out to them that the NSA might be able to get at
their data, they'd tell me "If the NSA wants it they can have it!"

It's mostly sales/accounting data.  They probably wouldn't even care if their
competitors got it. :-)

If off-net is a concern, then don't use Amazon.  It's not a concern for me or
any of my clients.
