Submission + - How to keep personal data secure? 2

ParanoidGuy writes: I'm facing a small dilemma and I was wondering if the slashdot crowd could offer me some suggestions. Suppose I have a personal database, hosted on a home server, which contains some personal information ranging from passwords to financial data. The question then becomes, how do I keep this data safe? Not be be overly paranoid, but I like that fuzzy feeling that you get from knowing that your data is truly safe.

My drives are already encrypted, as per usual, but I would like to encrypt my data in such a manner that is really is only accessible by me. I could simply run some symmetric encryption on it, but passwords tend to be either too weak, or too hard to remember without writing down somewhere. Also there's the chance that I might forget the password (and/or loose the piece of paper that it is written upon), at which time my data would become inaccessible.

I was then leaning more towards encrypting it with public/private key encryption and storing my private key on a usb stick. This however has a number of other problems, not the least of which is loosing the usb stick, someone copying the key that's on it, the flash drive dying of age...

Another idea builds on the previous one, where I make a backup of all the data with another set of keys and the private key to that is stored in like a bank safe or something, which would accessed in case something happened. (then longevity of the medium that is storing the key might become an issue)

So the question becomes, what is the safest way to keep your data truly secure with an eye to longevity, absolute security (as in, making sure only you have access, even in case something is compromised, if such a thing is possible), redundancy (in case something happens to the original scheme, you can still somehow access the data). Maybe it's a balancing act between security and accessibility, either way, I was wondering what the /. crowd would propose, maybe there are already solutions out there or maybe I'm being overly paranoid, any and all constructive opinions are welcome!
