I already got the point about TrueCrypt being open source and not going out of business, and it's well taken. However, if you aren't going to slow down and figure out what I'm asking, then how can I trust that you fully understand what you're preaching?

My point above about TrueCrypt is that you still have to store your data on an external database system. (We are talking about external backup over the Internet, not local backup.) That external database system can go out of business, just like Carbonite (or similar) can go out of business. However, if you're running Carbonite (or similar) you have a monthly bill. So, you're forced to keep track if and when Carbonite went out of business, and you can adapt in a timely manner.

In contrast, with the database where you store your TrueCrypt files, it's quite likely a person won't check the database but twice a year. So, although your TrueCrypt would be fully capable of decrypting your files, there may not be any files to decrypt. Unlikely? Well, we are talking about unlikely scenarios after all.

QUESTIONS:

Can you sync with TrudCrypt? I need to sync about 80 GB of data. In other words, I need it to update only the changed files. I like the idea of TrueCrypt, but if I can't sync, then I can't use.

What is a reliable external database for storing your TrueCrypt files? I need to store externally over the Internet. I'm NOT talking about local storage, and I'm NOT talking about saving to an external hard drive and physically taking it to an external location.
