Hi, Peviha
Not a freak. But perhaps more tech-savvy than the average user and more aware of privacy issues, etc..
In my case, I only have a desktop computer and I'm not interested in spending money on additional hard drives (or flash drives or whatever) to back up email or documents, etc. But I certainly do understand why others would want to do so.
In the particular case of email, I do have some emails that are very important to me (like irreplaceable ones from a friend who suddenly passed away last year), so I simply save them at several good, reputable email providers (Runbox, EuMX,
FastMail) as well as on my computer (in Outlook 2007).
I am not overly concerned about removing emails from servers to keep the gov't from seeing them. I figure, with gov't snooping being what it apparently is these days, there is as much a chance that they can (or will soon be able to) intercept the emails in transit at least as easily as trying to get them -- legally or otherwise -- while resting on a provider's servers.
But if I
were concerned enough to maintain strict privacy as much as I could, I would undoubtedly go your route: download them locally to an email client, remove them from the servers, and make multiple back ups on external media (and keep those multiple copies in different locations).
