comment Why not simply backup the TrueCrypt container file?
@WadihM. It's not that easy to answer, really. TrueCrypt uses XTS mode for the block ciphers. You see, XTS is pretty much ECB in that each block is independently encrypted (but with some "tweaks"). Patterns of empty space are quite easy to spot with XTS, and with enough backup samples it's possible to detect more patterns. There isn't much public work done on this, so it's hard to say. My original answer still applies; yes, it's possible, but there's nothing tangible yet.. it's only "pre-theoretical".
