Carlo,

My personal take on security and Dropbox.

... I think Dropbox IS a secure place to store your information. The fact
that it automates backup (while automatically encrypting your backup) means
it is a lot more secure than other forms of backup. And automated backups
of important data is really, really useful.

1. For very important data (such as username/password details for your
online banking), you can store your passwords using 1Password, and sync via
Dropbox.  1Password encrypts your data before it goes of your computer, so
even if someone did get hold of your 1Password data file, if you've used a
good password it is still going to be very secure - Dropbox could not
unencrypt it even it they wanted to. They do say that even if they are
asked to pass data over to law enforcement, they will remove their
encryption, but they cannot remove the encryption on your 1Password file
(and they say the don't try to remove any of your encryption anyway).

This article explains more about 1Password encryption:
http://help.agilebits.com/1Password3/cloud_storage_security.html

2. For most other scenarios, Dropbox still provides very secure data
storage. All your data is encrypted by Dropbox (AES-256 bit encryption). So
even if someone hacked Amazon S3 and was able to get your data files, with
a good password, AES 256 is *very* hard to unencrypt (nobody can say
impossible, but this standard is good enough for the US government and
banks).
The Dropbox privacy policy makes clear they can remove the Dropbox
encryption in certain situations (see their Privacy Policy), but they make
clear this is for rare events.

Data is usually at a lot more risk on a Mac than on Dropbox. A Mac can be
physically picked up and taken from your home or office, disks removed,
logins circumvented - if your data is unencrypted, it isn't going to be
hardif someone wants to get at your data.  if it is stored unencrypted.  If
it is stored in encrypted form, them Dropbox makes it doubly secure.

Nobody can guarantee 100% security once data is in electronic form. But
with 1Password and/or Dropbox, I think you have very easy to use tools that
give you good backup and very good security indeed.
