TrueCrypt sounds like a good tool (it's been covered on several 
"Security Now" podcasts, see grc.com), but not a good fit for a backup 
application. The encrypted view of the files will be as a block device 
or big file containing the file system. Any slight change within that 
file system results in a completely different looking blob of binary 
data. Not particularly efficient for backups.

Take a look at the rsynccrypto project.

I use KeyPass (KeyPassX on Linux) - a multi-platform password safe.

Of course it just defers the problem, as you still need to remember a 
master pass phrase, and optionally have a keyfile for KeyPass.
