Well i'm man enough to admit when he's wrong. It still seems like a vulnerability the more you update that TC volume and sync it to dropbox though. Also who's this Lilith you speak of eRe4s3r

Data is data, even if it's a container. Anything capable of backing up only delta changes in a SQL db should also be able to backup a Truecrypt volume.
Its pretty clear you dont understand how encryption works, and if it did work like you suggest then it would be easily defeated.
Uhm, yeah? No.

The relevant portion:
"Why Dropbox? Good question. Dropbox can synchronize only the changed portions of large files, while Google Drive and SkyDrive can only synchronize entire files (as far as I can tell). This means that, if you have a 2GB TrueCrypt drive and change a small file in it, Dropbox will upload a small portion of the TrueCrypt file, while Google Drive and SkyDrive will re-upload the entire 2GB file. Some other cloud storage services may also offer delta uploads – be sure you choose one that does if you’re using a TrueCrypt volume."

Can services like Dropbox do block-level syncing? For example, if you make a 1GB TrueCrypt volume, and modify 1MB of data inside it, does Dropbox need to send the whole 1GB back to the cloud, or can it just sync the blocks that changed?
If it can't do block level, that kinda kills any ability to do your own encryption, right? Or am I missing a tool that I should know about?

I will never understand why people who are concerned about privacy don't user services like Spideroak instead of Dropbox.

So basically dropbox advises you not to use dropbox if you care about who reads your stuff... that they have data encrypted on their servers is a flat out lie, every single dropbox employee can see and read your files. If they encrypted the data, they can decrypt it.
