Contingency plans

It recently struck me that my computer is host to years' worth of documents, emails, programs that I've written etc. that are irreplaceable. If my flat were to go up in flames, I'd lose the lot. This bothers me.

I bought a 4G USB memory stick (I'm loath to call it a "flash drive" because there's of course no "drive" in it; no mechanism, no moving parts) to use as a portable backup. 4G of space isn't enough to back up thalassa in entirety, of course; but it can easily hold all my personal files and the system configuration. I've put it on my keyring. My keys go everywhere with me, clipped to a belt loop.

It's not inconceivable that I might lose my keys. If that were to happen, anyone who were to find them would have access to my memory stick. I don't particularly want my personal files to be readable by any random person, so the backup is encrypted. The memory stick contains a huge file, which is a FAT32 filesystem encrypted using the Twofish algorithm with a 256-bit key (a passphrase, hashed using SHA-256). The encrypted filesystem is easily accessible using Linux's cryptographic subsystem. I've also put a copy of FreeOTFE on the memory stick, so I can get to my files using any random Windows machine in an emergency. (Gotta test that at work next week; the FreeOTFE documentation says that it's compatible with Linux's dm-crypt, but I need to make sure...)
