As far as I can tell from my own usage, the only portion that is uploaded is the changed portion. I have a 1GB container currently synced and when I change files in that container, I can assure you that it doesn't upload 1GB of information. It appears to only transfer the delta.
- jodrellblank 16y agoOne of the properties of a good hash algorithm is that a small change in the input makes a big change in the output, and one of the properties of a good encryption algorithm is that the output looks random. I don't know how the two are supposed to combine, but the prediction is that for a truecrypt disk image, any change in the contents produces a very different disk image all over - so transferring "the delta" is still a much larger amount than you'd expect. Although, if this were the case it would also have to rewrite the disk image a lot and that might be quite bad for just local use.
