It is good to know that the system that I am using is fairly secure
because it is working really well using EC2 compared to using s3sync
and s3fs to backup to  S3. The back up using EC2 ran flawlessly.  I
can make timed snapshots of my EC2 volume to S3 whenever I want.  When
I used s3sync and s3fs schemes with S3, I was constantly having
problems with broken links and data was not synced properly.  In my
opinion, the EC2 method is the best way to go.  EC2 cost $0.10 per
hour to run so it is expensive if you keep it running continuously but
very inexpensive if you boot it up, backup your data, and then
shutdown.  What I like most about using EC2 is that I understand how
it works.  I never understood how S3 works and so I needed to rely on
the s3sync and s3fs to work properly.  Once I clean up my script and
assure that it is working without incident, I will work on all the
suggestions posted to this tread.  Thanks for the advice
