Amazon S3 AWS new way to backup

[kramerjm-Re5JQEeQqe8AvxtiuMwx3w at public.gmane.org (James Kramer)]

I have read that it is possible to encrypt and compress the files but I just
made a mental note of the possibility of it and went on.  I should mention
that there is a maximum file size of 5 GB that can be mounted.
