That's not true. Dropbox uses librsync so small changes of big files yields small diffs, thus TrueCrypt volumes work just fine with Dropbox.

- missing_cipher 13y agoSpeaking out of ignorance here: But aren't TrueCrypt volumes completely changed when you add/remove something? I'm thinking similarly to a hash: The slightest modification changes it completely.
- throwit1979 13y agoIf that were the case, then terabyte-scale volumes would be prohibitively useless - and I know plenty of people with media volumes in TC.
- mkl 13y agoThat's not how it works - it would be inefficient to the point of uselessness to rewrite the entire file constantly, and my 100GB TrueCrypt volume is fast to save to.
- sigil 13y agoBut aren't TrueCrypt volumes completely changed when you add/remove something? No, the crypto in TrueCrypt doesn't amplify the number of changed blocks. But it does disperse the changed blocks throughout the encrypted image, and this does result in higher bandwidth used during the sync (at least with DropBox).
